Comparison of implant placement and loading protocols for single anterior maxillary implants: A systematic review and network meta-analysis. J Prosthet Dent 2024:S0022-3913(24)00412-8. [PMID: 39054170 DOI: 10.1016/j.prosdent.2024.05.033] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2024] [Revised: 05/31/2024] [Accepted: 05/31/2024] [Indexed: 07/27/2024]
Abstract
STATEMENT OF PROBLEM With increasing esthetic needs, patients prefer missing anterior teeth to be restored as soon as possible, but how the timing of implantation and prosthetic loading influences peri-implant tissue and the esthetic results remains unclear. PURPOSE The purpose of this systematic review and network meta-analysis of randomized controlled trials was to investigate and rank the hard-tissue and soft-tissue outcomes, esthetics, and patient satisfaction of single maxillary implant placement and loading protocols. MATERIAL AND METHODS A systematic search was conducted to identify studies with at least a 1-year follow-up that compared different implant placement and loading protocols and reported on survival, marginal bone loss (MBL), soft tissue, and esthetics. A random effects model and a Bayesian approach were applied to compare protocols by using mean differences (MD) with 95% credible intervals (CrI) and surface under the cumulative ranking curve (SUCRA) values. RESULTS A total of 43 articles were included, with a follow-up of 1 to 5 years. All protocols had high survival rates and no significant differences for 1-year or 2-year MBL. Immediate placement with immediate loading ranked first in pink and white esthetic scores and satisfaction and was statistically significantly better than immediate placement with delayed loading or late placement protocols in pink esthetic scores, where its advantage over late placement with late loading was also clinically relevant [MD: -1.74, CrI: -2.34 to -1.15]. CONCLUSIONS Immediate implantation with immediate loading showed a considerable esthetic advantage over later rehabilitation, whereas only a slight difference in MBL resulted from different protocols.

Abstract
Background Presently, modern regenerative and surgical techniques for immediate implant placement in prepared sockets with soft tissue grafts and bone substitutes have helped eliminate concerns about bone deficiency. This also allowed the placement of dental implants based on prosthodontic needs. Aim The present study aimed to comparatively assess dental implant healing following immediate implant placement with or without bone graft and dental implant healing after delayed implant placement with or without bone graft. Methods The study included 120 study subjects that were divided into two groups. Group I for immediate implant placement with or without bone graft (n=60) and Group II for delayed implant placement with or without bone graft (n=60). These two groups were further divided into subgroups. Group I subjects were further divided into two subgroups, where Group A (n=30) subjects underwent immediate implant placement with bone graft and Group B (n=30) subjects were given immediate implant placement without bone graft. Group II participants were further divided into two subgroups, where Group C (n=30) subjects underwent delayed implant placement with bone graft and Group D (n=30) subjects underwent delayed implant placement without bone graft. In the two groups, crestal bone levels were compared radiographically preoperatively and postoperatively at the immediate postoperative time, three months, and six months. Results More reduction in the crestal bone level was seen in the immediate implant placement group at three and six months postoperatively compared to the delayed implant placement group. A non-significant reduction in crestal bone levels was seen in the immediate implant placement with bone graft group with p>0.05 at three and six months compared to immediate implant placement without bone graft. Similar, non-significant crestal bone loss was seen in the delayed implant placement with bone graft group at three and six months compared to delayed implant placement with bone graft. Conclusions This study concluded that healing of crestal bone in the delayed implant placement group with or without bone graft is better in comparison to the immediate implant placement group with or without bone graft.

JOURNAL OF ADVANCED PERIODONTOLOGY & IMPLANT DENTISTRY 2024; 16:15-21. [PMID: 39027205 PMCID: PMC11252158 DOI: 10.34172/japid.2024.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 03/09/2024] [Indexed: 07/20/2024]
Abstract
Background This research aimed to evaluate the clinical characteristics of pain and wound healing and serological inflammatory markers after full-mouth implantation in one session compared to several sessions. Methods A single-masked clinical trial was conducted on 20 patients (n=10) receiving full-mouth implants. Patients were randomly divided into two groups. The first group was operated under general anesthesia in one session and the second group in multi-sessions. Inflammation level was evaluated through white blood cell (WBC) and serum C-reactive protein (CRP) before and after surgery by a blood test. Pain and early wound healing (EHS) assessment was conducted after surgery with VAS and EHS indicators, respectively. Serological and clinical parameters were compared by repeated-measures ANOVA and Sidak and Man-Whitney U tests, respectively, using SPSS 20. Results The CRP level 48 hours postoperatively was not different in the two groups; however, seven days after treatment, it was higher in the multi-session group than in the single-session approach. The WBC was not different between the two groups at evaluated intervals. Serum levels of WBC and CRP increased 48 hours postoperatively and decreased seven days later. EHS showed no difference between the two groups at the three investigated intervals. The amount of VAS 24 and 48 hours and 7 days postoperatively was higher in multi-session surgery than in the one-session approach. In both groups, VAS was not different at 24 and 48 hours postoperatively and decreased over seven days. Conclusion Full-mouth implant surgery under general anesthesia in one session caused less inflammation and pain postoperatively while presenting the same wound-healing process as the multi-session surgery.

Impact of immediate interim restoration on peri-implant tissues around immediately placed single dental implants in the esthetic region: A systematic review and meta-analysis. J Prosthet Dent 2024:S0022-3913(24)00045-3. [PMID: 38355364 DOI: 10.1016/j.prosdent.2024.01.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 01/10/2024] [Accepted: 01/12/2024] [Indexed: 02/16/2024]
Abstract
STATEMENT OF PROBLEM Immediate implant placement with an immediate interim restoration is a well-established protocol. Nevertheless, a consensus regarding the impact of immediate interim restoration on peri-implant tissues around single dental implants is lacking. PURPOSE The purpose of this systematic review and meta-analysis was to address the research question: "Does the placement of an immediate interim restoration influence the mid-facial mucosal (MFM) marginal and interdental papilla (IDP) levels around single dental implants placed in the anterior esthetic region by using an immediate implant placement protocol?" MATERIAL AND METHODS A comprehensive literature search was made in the Medline/PubMed, Scopus, Cochrane, and Science Direct electronic databases for articles published in English evaluating the impact of immediate interim restoration on peri-implant tissues around single dental implants in the anterior esthetic region. The primary outcomes assessed were changes in the MFM marginal and IDP levels. Additional outcomes were marginal bone (MB) loss, esthetic outcomes involving the pink and white esthetic scores (PES and WES), implant survival rates, and patient reported outcome measures (PROMs). The risk of bias assessment was performed by using the RoB 2 tool for randomized trials and the Newcastle-Ottawa scale for nonrandomized studies. Meta-analysis was performed by using random and fixed effects model (α=.05) in the RevMan software program. RESULTS Sixteen studies were included that analyzed 836 single dental implants involving 823 patients. The meta-analysis showed no significant differences in implants with and without interim restoration in terms of MFM marginal level (MD=0.01; 95% CI=-1.23 to 1.25; P=.98), mesial IDP level (MD=0.12; 95% CI=-0.23 to 0.47; P=.50), distal IDP level (MD=0.20; 95% CI=-0.40 to 0.79; P=.52), and MB loss (MD=0.01; 95% CI=-0.42 to 0.43; P=.97). The systematic analysis for survival rates determined no notable difference in implants with or without an interim restoration. However, the esthetic outcomes and PROMs substantially improved with immediate interim restorations. The RoB 2 tool showed a moderate to low risk of bias, and the Newcastle-Ottawa scale indicated high-quality studies. CONCLUSIONS After a 12-month follow-up, immediate interim restoration had no significant impact on peri-implant soft (MFM marginal and IDP levels) and hard tissues (MB loss) around immediately placed single dental implants. Nevertheless, additional well-designed and well-implemented clinical trials with long-term follow-up periods are needed to provide more precise evidence-based recommendations.

Heterogeneity of outcomes in randomized controlled trials on implant prosthodontic therapy is hindering comparative effectiveness research: meta-research study. BMC Oral Health 2023; 23:908. [PMID: 37993826 PMCID: PMC10666438 DOI: 10.1186/s12903-023-03658-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 11/12/2023] [Indexed: 11/24/2023] Open
Abstract
BACKGROUND Consistency in outcomes across clinical trials allows for comparing and combining results from different studies. A core outcome set (COS), representing a minimally agreed standardized group of outcomes that should be monitored and measured through research in a specific field of medicine, is not yet available for trials in implant prosthodontic (dental implant) therapy. This meta-research study aimed to analyze outcomes used in clinical trials on implant prosthodontic therapy. METHODS We searched the Cochrane Oral Health Group (COHG) register to identify systematic reviews of interventions in implant prosthodontic therapy published by October 2023. From the randomized controlled trials (RCTs) included in the relevant reviews, we extracted data on the characteristics of the included trials and the outcomes used. We categorized outcomes into domains. RESULTS From 182 systematic reviews in the COHG register, we included 11 systematic reviews on dental implant therapy. The reviews included 117 unique RCTs with 4725 participants, published from 1995 to 2020, which analyzed 74 different outcomes. Using different definitions, implant failure was analyzed in 73 RCTs. Seventeen RCTs did not define implant failure. Failure was most often (30 RCTs) followed up for one year. Only one RCT assessed implant failure after five years. Trials used 17 definitions of implant failure, while 17 trials did not report on the criteria of implant failure. Complications were analyzed in 48 RCTs, although they were not clearly defined in 12 RCTs. Failure of prosthodontic supra-structure was analyzed in 74 RCTs, with definitions of failure and criteria not clearly defined in 44 RCTs. Trials considered adverse events, peri-implant tissue health, patient attitudes, and other outcomes, including cost, aesthetics, or procedure duration. These outcomes were often different between trials. Twenty-six outcomes were used only once per study. CONCLUSIONS Clinical trials in implant prosthodontics used different outcomes, different definitions of outcomes and used different times to monitor them. Standardization of outcomes is necessary to allow comparability and evidence synthesis about the effectiveness of implant prosthodontic therapy.

Abstract
OBJECTIVES The aim of this study was to review available evidence for Type 1A (immediate implant placement and immediate loading) of single tooth replacement in the maxillary esthetic zone. MATERIALS AND METHODS An electronic search was conducted utilizing the databases of MEDLINE, Embase, and Cochrane to identify publications reporting on the outcomes of Type 1A for single tooth replacement in the maxillary esthetic zone. The success and survival rates of the included articles were reported, which were further categorized according to the clinical criteria reported in Type 1A. Mean survival rates were univariately compared between risk groups and additionally between studies published before and since 2012 using bias-corrected and study size-weighed bootstrap tests. A study time-correcting meta-analysis was then performed to obtain an overall effect for the study pool. RESULTS A total of 3118 publications were identified in the search, with a total of 68 articles included. A mean number of implants per study were 37.2 and mean follow-up was 2.8 years. All the included studies utilizing Type 1A report highly selective inclusion and exclusion criteria. Univariate risk group comparison determined that studies before 2012 report a significantly lower mean survival rate (difference of -1.9 percentage points [PP], 95% CI: [-0.3, -4.0], p = .02), facial gap dimension had an impact on survival rates (+3.1 PP [0.2, 5.3] for width >2 mm, p = .04), as well as presence of endodontic infection (+2.6 PP [0.9, 5.1], p = .004). CONCLUSIONS Type 1A has a high survival rate in studies reporting strict patient and site selection criteria. Further research is required to assess esthetic and functional success with Type 1A treatments.

Abstract
Background The decision-making of the most appropriate provisional restoration option in single-tooth implant practice is complex under multi-criteria conditions. The aim of our study is to conduct a case study on the determination of the appropriate provisional treatment option to be used in a single-tooth dental implant interim period after placement with the help of an entropy-based additive ratio assessment. Methodology Eight important criteria for fulfilling this purpose have been extracted from the literature search: "esthetic potential," "patient comfort," "treatment time," "laboratory cost," "occlusal clearance," "ease of removal," "durability," and "ease of modification." Provisional treatment alternatives are "removable partial denture," "vacuum-formed appliances," "bonded extracted tooth or denture," "metal or fiber-reinforced resin-bonded fixed partial denture," "wire-retained resin-bonded fixed partial denture," "acrylic resin provisional fixed partial denture," and "implant-supported fixed provisional restoration." It has been examined which of these alternatives is most appropriate in terms of both reported specifications and artificially generated dominance scenarios. The scenarios employed are S0 (criteria are equal-weighted), S1 (the criterion is tri-fold dominant), and S2 (the criterion is two-fold dominant). Results "Patient comfort" was the most important criterion (wj = 0.19). The remaining criteria were ranked as "modifications," "treatment time," "durability," "esthetic potential," "laboratory cost," "occlusal clearance," and "ease of removal." The "implant-supported fixed provisional restoration" treatment option had the maximum degree of utility in the S0 (Ki = 0.782) and S2 (Ki = 0.80) categories. If "treatment time" or "occlusal clearance" is the dominant variable, "vacuum-formed appliances" had the highest degree of utility (Ki = 0.69) in S1. Conclusions According to the rankings and scenarios created utilizing entropy-based additive ratio assessment methods, the "implant-supported fixed provisional restoration" is the appropriate provisional option for a single-tooth implant treatment. If "treatment time" or "occlusal clearance" is an absolute criterion, the "vacuum-formed provisional appliance" will replace the appropriate option.

Abstract
This study evaluated the two-year clinical outcomes of 3.1 mm diameter dental implants, immediately provisionalized and later restored using same-day dentistry, in 10 patients receiving 11 narrow-diameter (3.1 mm) single implants. Each implant was placed and immediately restored with a provisional crown after placement. At least 2 months after placement, the implant was restored with a prefabricated titanium abutment and an all-ceramic crown using a same-day dentistry protocol. Clinical outcomes, including apical bone loss, probing depths, gingival index, and surgical and prosthetic complications, were documented. There was no implant failure over the course of two years. No surgical complications were reported. Two cases lost provisional crowns. One crown needed to be remade due to esthetic concern. The cumulative two-year survival rate of the implants was 100%. Implant bone loss after two years of functional loading was −0.56 ± 0.54 mm and −0.32 ± 0.68 mm for mesial and distal crestal bone, respectively. Two prosthetic complications included recementation of a crown and remaking of a crown. This exploratory study suggests that immediate provisionalization and a same-day restorative dentistry digital workflow protocol for narrow-diameter implants appear to be predictable clinical procedures with no reported surgical complications and minimal prosthetic complications.

Abstract
Customized healing abutments have been introduced in clinical practice along with implant surgery to preserve or create natural-appearing hard and soft tissue around the implant. This provides the benefits of reducing the overall treatment time by eliminating the second stage and reducing the elapsed time of the fabrication of the final prostheses. This article aims to review the types and properties of materials used for the fabrication of customized healing abutments and their clinical applications. Articles published in English on customized healing abutments were searched in Google Scholar, PubMed/MEDLINE, ScienceDirect, and the Scopus databases up to August 2022. The relevant articles were selected and included in this literature review. Customized healing abutments can be fabricated from materials available for dental implants, including PEEK, PMMA, zirconia, resin composite, and titanium. All the materials can be used following both immediate and delayed implant placement. Each material provides different mechanical and biological properties that influence the peri-implant tissues. In conclusion, the studies have demonstrated promising outcomes for all the materials. However, further investigation comparing the effects of each material on peri-implant soft and hard tissues is required.

Abstract
PURPOSE The aim of this prospective cohort study was to assess the facial-palatal ridge dimensional changes that occurred at 8-10 months following flapless dual-zone (DZ) immediate implant placement and socket-shield (SS) immediate placement in the maxilla. MATERIALS AND METHODS A total of 19 patients who received 20 implants were included, with 10 implants (MegaGen AnyRidge) placed for each treatment, DZ and SS. Cast models were made at 8-10 months after implant placement to assess the dimensional ridge changes by measuring the facial-palatal ridge width on implant sites (T) at six designated points starting from the gingival margin (0, 1, 2, 3, 5 and 7) and comparing it with the corresponding measurement on the contralateral tooth site (C). RESULTS All 20 implants demonstrated successful osseointegration at 8-10 months follow-up (survival rate 100%). Two out of ten cases of SS group presented with minor manageable complications of external shield exposure. DZ group showed an average of 0.3 mm facial-palatal ridge width reduction, while SS group revealed a mean gain in ridge width of approximately 0.2 mm at 8-10 months follow-up. CONCLUSION When comparing between two treatments, there was a significant difference in ridge width change at 8-10 months following implant placement, indicating better preservation of the ridge contour for socket shield technique.

Abstract
This article describes a case with a full digital procedure to prefabricate an implant-supported interim restoration based on the preoperative digital implant planning. A fully guided surgical template is designed and printed, and then an interim restoration is fabricated based on the planned implant position through a dental computer-aided design (CAD) software. Once the implant was placed at the predetermined position through the fully guided surgical guide, the prefabricated interim restoration could be inserted immediately after the surgery, which can guide the healing of the soft tissue and enhance the esthetic outcomes. This novel technique eliminates the conventional impression making to insert an implant-supported interim restoration immediately after the implant placement surgery, which can guide the healing of the soft tissue, minimize the chairside time and optimize the clinical workflow.

Abstract
AIM This study aims to compare three different drilling techniques for implant site preparation to enhance the primary stability of the early loaded single implant in the posterior maxilla. MATERIALS AND METHODS A total of 36 dental implants were used in this study for the replacement of a missing single tooth or more in the maxillary posterior region with an early loaded dental implant. The patients were randomly divided into three groups. In group I, the drilling was performed using an undersized drilling technique, in group II, the drilling was performed using bone expanders, and in group III, the drilling was performed using the osseodensification (OD) technique. Patients were evaluated clinically and radiographically at regular time intervals immediately, 4 weeks, 6 months, 1 year, 2 years, and 3 years after surgery. All clinical and radiographic parameters were subjected to statistical analysis. RESULTS All implants in group I were stable and successful, while 11 from 12 implants survived in both groups II and III. There was no significant difference in peri-implant soft tissue health and marginal bone loss (MBL) throughout the whole study period between the three groups, while there was a significant difference in implant stability and insertion torque between groups I, II, and III at the time of implant placement. CONCLUSION Preparing the implant bed using the undersized drilling technique with drills with similar geometry to the implant being inserted provides high implant primary stability without the need for additional instruments or cost. CLINICAL SIGNIFICANCE Dental implants can be early loaded in the posterior maxilla by using an undersized drilling technique, as it improves primary stability.

Abstract
PURPOSE Implant-supported prosthetic rehabilitation in the resorbed maxilla is a great challenge. The aim of this study was to determine the survival rate of conventional anterior implants placed in combination with zygomatic implants according to the Brånemark technique, and to identify risk factors for implant failure. METHODS We collected data retrospectively from 72 consecutive patients who received treatment from 1998 to 2018 at our center, according to Brånemark's original technique. Kaplan-Meier analysis was conducted to assess survival rate, and a survival regression model was used with the patient as the random factor, applying the Weibull distribution. RESULTS A total of 236 maxillary anterior implants were included, with a mean follow-up of 12.1 years. Kaplan-Meier analysis showed overall cumulative survival rates of 95.3% at 1 year, 94.8% at 2 years, 93.0% at 5 years, 90.5% at 10 years, 81.6% at 15 years, and 67.7% at 20 years. Survival regression showed an association between bruxism and implant failure as well as implants bearing an overdenture. Implants with length ≤ 10 mm had a significantly lower survival time. No significant association was found between the number of anterior implants and survival rate. CONCLUSIONS We found acceptable long-term anterior conventional implant survival. Significant risk factors for failure were bruxism, overdentures, and implants shorter than 10 mm.

Abstract
This study examined the success rates of single immediate implants and their associated biological, hardware and aesthetic complications. Using a developed search strategy, randomized controlled trials (RCTs) on single-unit immediate implants with at least six human participants, a minimum follow-up time of 12 months and published between January 1999 and January 2021 were identified. Data was extracted independently using pre-designed data extraction forms. Information on success rates and associated biological, hardware and aesthetic complications were obtained and assessed. Out of 191 potentially eligible studies, 26 RCTs assessing 1270 patients with a total of 1326 single implants were included and further evaluated. In this review, success rate was reported to be 96.7–100% over a total of 9 studies. However, there was a lack of consensus on a universal success criterion between authors emphasizing the need for agreement. The average follow up was 29 months and most reported complications were aesthetic (63 cases, 4.7%), whilst there were relatively fewer biological, (20 cases, 1.5%), and hardware complications (24 cases, 1.8%). Success rate is an uncommon clinical outcome with 9 out of 26 of the selected RCTs reporting it. In these studies, single immediate implants showed a high success rate with low numbers of biological and hardware complications, and high patient satisfaction with aesthetics were reported in the short-term follow-up of one year.

Abstract
The concept of immediate tooth replacement therapy (ITRT) in the esthetic zone has become a viable treatment modality and widely accepted in clinical practice. However, achieving adequate primary stability that enables immediate provisional restoration and desirable space for bone-grafting with conventional tapered body implant designs is challenging. The macro-hybrid implant design with a prosthetic angle correction and body-shift feature in a singular form provides not only greater primary stability of a wider diameter implant but also circumferential gap distance both facially and interproximally preserve the labial bone plate and interdental attachment apparatus of the adjacent natural teeth thereby maintaining the interdental papilla. The present clinical series exemplifies the clinical advantages of this inverted body-shift implant design in ITRT in various clinical scenarios in (1) single tooth replacement in a Type 1 intact socket with a thin periodontal phenotype, (2) single tooth replacement in a Type 2 socket with a dentoalveolar dehiscence of the labial bone plate, and (3) multiple adjacent teeth replacement of two maxillary central incisor. CLINICAL SIGNIFICANCE: The macro-hybrid design implant with a prosthetic angle correction and body-shift feature in a singular form provides greater midfacial gap distance as well as tooth-to-implant distance to preserve the interdental attachment of the adjacent natural teeth thereby leaving the interdental papilla undisturbed, without sacrificing higher primary stability afforded by larger diameter implants.

Abstract
OBJECTIVE The purpose of this study was assessment of the changes in soft and hard tissues in the esthetic zone of maxilla following immediate implant placement (IIP) with and without the socket shield technique (SST) and placement of implants 4 months following socket preservation (DIP) in terms of alterations in crestal bone thickness (CBT) and soft tissue changes evaluated by means of pink esthetic scores (PES) following placement of implants in the esthetic zone of maxilla. MATERIALS AND METHODS In the maxillary esthetic region, 75 dental implants were placed totally, with 25 implants each in the SST, IIP, and DIP groups. All participants were subjected to undergo CBCT for assessing the variations in thickness of crestal aspect of facial/buccal/labial alveolar bone (CBT). PES and PROMS (patient-related outcome measures) were assessed using VAS for pain threshold and esthetic satisfaction following implant placement and after 6th post-operative month. RESULTS The mean reduction in CBT showed a statistically significant difference between and within the groups, in comparison to IIP and DIP groups, which demonstrated an average reduction in CBT 0.4 ± 0.1 and 0.2 ± 0.1 at 6 months following implant placement, respectively. The SST group showed a significantly lesser reduction in CBT of 0.05 ± 0.02. However, the mean difference in PES within and among the groups showed no significant difference statistically at P < 0.05. On comparison of individual scores of PES between the groups, the results showed significant difference statistically at P < 0.001. CONCLUSION The SST group demonstrated minimal reduction in CBT and a superior PES at the end of 6 months compared with the IIP and DIP groups.

Abstract
OBJECTIVES To address the following question: "Is the timing of implant placement and/or loading influencing the esthetic outcomes of implant-supported single crowns?" MATERIAL AND METHODS A literature screening was performed in four electronic databases until June 2020. Randomized controlled clinical trials with a minimum of 10 patients and 1 year of follow-up and reporting on dimensional changes of the peri-implant mucosa (midfacial recession, papilla level) and esthetic indexes were included. Cochrane Risk of Bias Tool was used, and comparable trials were subjected to meta-analyses. RESULTS Out of 8549 articles, 72 full-text articles were assessed for eligibility and 18 were included. Nine trials evaluated the timing of implant placement, and nine trials evaluated the timing of loading. The included trials comparing immediate implant placement to delayed implant placement evaluating the midfacial recession reported heterogeneous findings. No differences were found at 1 and 2-years, when comparing midfacial recession and papilla level between immediate and early implant placement. In immediate and delayed implant placement, when comparing conventional and immediate loading, the midfacial mucosal margin change was not statistically significant at the 1-year follow-up. When evaluating the timing of implant placement and/or loading the included trials found no differences in the Pink Esthetic score, White Esthetic score, and Papilla Index between groups. CONCLUSIONS Both immediate and early implant placement protocols presented stable treatment results in terms of esthetic outcomes at the 1-, 2-, and 10-years follow-up. Loading protocols did not seem to influence esthetic outcomes in short- and medium-term follow-ups.

Abstract
INTRODUCTION Although retrospective analysis has shown immediate placement of implants (IIP) in the maxillary esthetic zone showing promising outcomes compared to delayed placement of implants following socket preservation (DIP), a direct comparison in a prospective, well-designed randomized fashion with adequate power analysis between the two implant placement protocols is still lacking. This study is aimed at radiographically evaluating the effect of IIP after extraction as compared to implant placed in preserved sockets 4 months following extraction (DIP) in terms of changes in buccal plate thickness(CBT) after 6 months of healing and evaluation of pink esthetic score (PES) for assessment of soft tissue changes and patient-related outcome measures (PROMs) using visual analogue scale (VAS). MATERIALS AND METHODS 25 implants were placed immediately following extraction in the IIP group, and 25 implants were placed four months following socket preservation with demineralized bovine bone mineral (DBBM) and advanced platelet-rich fibrin (A-PRF) in the DIP group, control group, in the maxillary esthetic region. CBCT was taken preoperatively and 6 months postoperatively to assess the dimensional changes in the buccal bone plates(CBT). PES and PROMs for pain threshold and patient satisfaction using VAS were evaluated at the time of implant placement and 6 months postoperatively. RESULTS Significant differences in mean reduction in buccal plate thickness (CBT) were found in the test group (IIP) 0.2 ± 0.02 compared to the control group (DIP) which showed a mean reduction in CBT of 0.4 ± 0.1 (p < 0.001) at the end of 6 months. Although there was no statistically significant difference in PES between the groups, there was a significant difference between the groups when individual values of PES were compared at p < 0.001. CONCLUSION The IIP group showed lesser reduction in CBT and a better PES which is an important clinical information which could be translated clinically in situations where implant placement is planned in the maxillary esthetic region. This trial is registered with CTRI/2019/06/019723.

Abstract
OBJECTIVES Comparing PES/WES scores, modified success rate, survival, success, buccal bone thickness and patient-reported outcomes of immediate dental implants placed in fresh alveolar sockets using a flap or a minimal split-thickness envelope flap (MSTEF). MATERIALS AND METHODS Implants following random assignment into a flap or MSTEF group were placed immediately in anterior and premolar areas. Guided bone regeneration and autogenous connective tissue graft were used in all cases. A temporary prosthesis was provided followed by the final prosthesis at 16-18 weeks. Success and survival rates together with radiographic buccal bone thickness and patient satisfaction were evaluated at 12-month post-loading. The aesthetic outcome was evaluated through the Pink (PES) and White (WES) Aesthetic Score by 8 blind clinicians of different training background and incorporated in modified success criteria. RESULTS 28 implants were placed on 28 patients. No statistically significant differences were noted in PES (10.54 control versus 10.80 test), WES scores (6.97 control versus 6.95 test) or success criteria including aesthetic parameters (modified success criteria) for the different specialty groups (Range 69%-92%). In addition, no statistically significant differences were noted in survival (100%), success (100%), buccal wall thickness between control (0.72 ± 0.22) and test group (0.92 ± 0.31) and patients' reported outcomes. CONCLUSIONS Immediate dental implant treatment with flap/ MSTEF provided similar mean PES/WES scores, modified success rate, survival, mean buccal bone levels and patients' satisfaction. However, aesthetic failures were common in both groups.

Abstract
AIM The aim of this systematic review was to evaluate the efficacy of immediate implant placement (IIP) compared to implants placed after alveolar ridge preservation (ARP) in terms of clinical, esthetic, and patient-reported outcomes. METHODS A manual and electronic search (National Library of Medicine) was performed for controlled clinical trials, with at least 12 months of follow-up. Primary outcome variable was implant survival and secondary outcomes were marginal bone level (MBL) (change), pink esthetic score (PES), mid-facial mucosal level (change), papilla index score, complications, and patient-reported outcomes. RESULTS A total of 10 publications were included (7 randomized clinical trials and 3 controlled clinical trials). The results from the meta-analyses showed that survival rate was significantly lower in the IIP group compared to ARP group [RR = 0.33; 95% CI (0.14; 0.78); p = 0.01]. No significant differences between the two groups were observed regarding radiographic MBL, PES scores, or mid-facial mucosal level (p > 0.05). CONCLUSION The results from this systematic review and meta-analysis showed that IIP had lower survival rates and similar esthetic results when compared to ARP. CLINICAL RELEVANCE Clinicians should weigh the benefits and disadvantages of each intervention to select the optimal timing of implant placement.

Abstract
OBJECTIVES To assess the effect of connective tissue graft (CTG) in terms of vertical mid-facial soft tissue change when applied at the buccal aspect following single immediate implant placement (IIP). MATERIALS AND METHODS Two independent reviewers conducted an electronic literature search in PubMed, Web of Science, EMBASE and Cochrane databases as well as a manual search to identify eligible clinical studies up to January 2020. Randomized controlled trials (RCTs) and non-randomized controlled studies (NRSs) comparing IIP with CTG and without CTG over a mean follow-up of at least 12 months were included for a qualitative analysis. Meta-analyses were performed on data provided by RCTs. RESULTS Out of 1814 records, 5 RCTs and 3 NRSs reported on 409 (IIP + CTG: 246, IIP: 163) immediately installed implants with a mean follow-up ranging from 12 to 108 months. Only 1 RCT showed low risk of bias. Meta-analysis revealed a significant difference in terms of vertical mid-facial soft tissue change between IIP + CTG and IIP pointing to 0.41 mm (95% CI [0.21; 0.61], p < .001) in favour of soft tissue grafting. This outcome was clinically relevant since the risk for ≥1 mm asymmetry in mid-facial vertical soft tissue level was 12 times (RR 12.10, 95% CI [2.57; 56.91], p = .002) lower following IIP + CTG. Soft tissue grafting also resulted in a trend towards less bleeding on probing (MD 17%, 95% CI [-35%; 1%], p = .06). Meta-analyses did not reveal significant differences in terms of pink aesthetic score, marginal bone level change and probing depth. Results were inconclusive for horizontal mid-facial soft tissue change and papilla height change. Based on GRADE guidelines, a moderate recommendation for the use of a CTG following IIP can be made. CONCLUSION CTG contributes to mid-facial soft tissue stability following IIP. Therefore, CTG should be considered when elevated risk for mid-facial recession is expected in the aesthetic zone (thin gingival biotype, <0.5 mm buccal bone thickness).

Abstract
This clinical report describes a staged approach using a removable partial denture (RPD) and a transitional implant-supported overdenture as interim prostheses in treating a failing anterior dentition with posterior implant-supported fixed dental prostheses (FPD), until the time a full-arch fixed implant-supported prosthesis may be inserted. The RPD replaced the anterior teeth following their extraction and during implant osseointegration. The implant-supported overdenture rehabilitated the arch during the fabrication phase of the definitive restoration.

Abstract
INTRODUCTION There are mixed results regarding the aesthetic advantage of immediate provisionalization of dental implants. Therefore, this study aimed to compare facial mucosal level of single immediately placed implants with and without immediate provisionalization. METHODS Single implants were immediately placed to replace a hopeless maxillary anterior or premolar tooth in 40 subjects. Each implant was randomly assigned to receive a non-occluding temporary crown or a healing abutment after implant placement. At 4 months, these implants were permanently restored and followed up for 12 months. Clinical and radiographic parameters were measured and compared. RESULTS The implant survival rate at 12 months in the test and control group was 90% and 100%, respectively. Mid-facial mucosal marginal level and papilla height changes were minimal within groups, and no significant differences were found between the two groups. The amount of marginal bone remodelling was modest, with no significant difference between the two groups. Radiographic bone changes were not statistically different between the groups, except for the vertical crestal bone resorption. CONCLUSION Immediate implant placement with or without provisionalization can achieve stable vertical soft tissue level for 12 months as compared to pre-extraction level. However, immediate provisionalization was not able to improve the aesthetic outcome further.

Abstract
PURPOSE To measure dimensional changes of the periimplant soft tissue profile after removal of a single implant fixed interim restorations using digital impression procedures. MATERIALS AND METHODS Ten participants presenting with single implant-supported fixed interim restorations (ISFIRs) on the maxillary esthetic zone. A 2-step silicone impression was made of the maxillary arch with the ISFIRs. The experimental procedure was obtained by making digital impressions of the gingival contours immediately after ISFIR removal. The control procedure was formed by fabricating definitive casts from the conventional impression using the ISFIRs as a customized impression transfer and making digital impressions of these definitive casts. Both images of paired groups were digitally overlapped on the computer, and their profiles were measured at the coronal, midlevel gingiva in the buccolingual and mesiodistal width. RESULTS Statistically significant differences between the ISFIR emergence profile width and the unsupported soft tissue profile width were observed at the midlevel gingiva in the buccolingual dimension (1.35 mm) and at the coronal (0.51 mm) and midlevel gingiva (1.29 mm) in the mesiodistal dimension. CONCLUSIONS A digital impression, as used in this pilot study, does not capture accurately the desired soft tissue dimensions immediately after removal of the ISFIR.

Abstract
Since the introduction of immediate implant placements, the buccal bony wall has been a major consideration for success due to its correlation with soft tissue contour and color. This report presents the stability of the buccal wall thickness of an immediately placed implant at the anterior maxilla over 10 years. Although the width of the buccal wall decreased at the 2-year post-op follow-up, it remained stable afterward according to cone beam computerized tomography (CBCT) scans. Hence, this report suggests that ensuring adequate bony wall thickness with bone augmentation and fixture position may promise the longevity of the buccal bony wall and surrounding soft tissue in an immediate implant placement.

Abstract
The aim of this systematic review and meta-analysis was to compare the survival rate of the implants and the peri-implant tissue changes associated with implants inserted in fresh extraction sockets and those inserted in healed sockets. This review has been registered at PROSPERO under the number CRD42016043309. A systematic search was conducted by two reviewers independently in the databases PubMed/MEDLINE, Embase, and the Cochrane Library using different search terms; articles published until November 2016 were searched for. The searches identified 30 eligible studies. A total of 3,049 implants were installed in a total of 1,435 patients with a mean age of 46.68 years and a minimum of 6 months of follow-up. The survival rate of delayed implants (98.38%) was significantly greater than immediate implants (95.21%) (p=.001). For the marginal bone loss (p=.32), implant stability quotients values (p=.44), and pocket probing depth (p=.94) there was no significant difference between the analysed groups. The immediate implants placed in fresh sockets should be performed with caution because of the significantly lower survival rates than delayed implants inserted in healed sockets.

Abstract
The development of clinical implant dentistry was intensively affected by dental implant design improvement and innovation, which brought about new concept, even milestone-like changes of clinical protocol. The current improvements of dental implant design and their clinical importance could be highlighted as followings: 1) The implant apical design influences the implant preliminary stability in immediate implant. The apical 3-5 mm design of implant makes implant stable in immediate implant, because this part would be screwed into alveolar bone through fresh socket, the other part of implant could not be tightly screwed in the socket because of smaller implant diameter. Implant apical form, screw design, self-taping of apical part would be essential for immediate implant. 2) The enough preliminary stability of implant makes immediate prosthesis possible. When osseointegration does not occur, the implant stability comes from a mechanical anchorage, which depends on implant form, screw thread and self-taping design. 3) Implant neck design may have influence for soft tissue recession in esthetic zone. The implant with large shoulder would not be selected for the esthetic area. The platform design may be more favorable in the area. 4) The connection design between implant and abutment is thought a very important structure in implant long-term stability. Moose taper and "tube in tube" were well documented structure design in 20-year clinical practice in Peking University. 5) In last 15 years, the plenty studies showed the platform design of implant had positive influence in implant marginal bone level. Whatever in single implant restoration or multi-implant prosthesis. 6) The digital technology makes clinical work more precise and high-tech. This would be a trend in implant dentistry. New generation of chair-side digital computer-aided design/computer-aided manufacturing makes immediate prosthesis without conventional impression possible. 7) New abutment design have changed clinical protocol greatly. The All-on-four concept and Weldone concept benefit both from the abutment innovation, which were large angulated abutment and special welding abutment materials.

PURPOSE The aim of this study was to evaluate the possible factors that influenced the periimplant soft tissue changes around single implants-abutments with laser-microtextured surface (LMS) in the esthetic zone. MATERIALS AND METHODS Thirty-nine units, formed by implant-abutment with LMS were studied. Variables possibly associated with the periimplant soft tissue changes were obtained from clinical measurements (plaque [present/absent], periimplant biotype [thin/thick], and probing depth); intrasurgical measurements (vertical height in millimeters of the keratinized gingiva in the vestibular part of the implant site vestibular keratinized gingiva [VKG], implant vestibular crestal exposition, vestibular crestal level, and vestibular bone width); cast models (implant position [buccal/palatal], implant abutments angle); periapical radiographs (distance from the contact point to the interproximal bone crest of the adjacent tooth [CP-BC], distance from the contact point to the implant platform [CP-P], distance from the contact point to the first bone to implant contact [CP-IB]); and digital clinical photographs. Fisher exact test was used to determine the influence of each factor on the papilla level and on the facial marginal mucosal level. RESULTS The papillae level at the implant sites was significantly associated with the distance from the contact point to the alveolar bone crest, whereas no association was found with other variables. Periimplant biotype, differences in the VKG, CP-BC, and CP-IB were found associated with the different facial marginal mucosal level groups. CONCLUSIONS This study showed that the papilla level at single-tooth implants-abutments with LMS in the anterior maxilla was mainly influenced by the interproximal bone crest level of the adjacent tooth, whereas the marginal mucosal level was affected by periimplant biotype, facial bone crest level, and crestal implant exposition.

Abstract
INTRODUCTION Ever since its introduction in 1977, a minimum of few months of period is required for osseointegration to take place after dental implant surgery. With the passage of time and advancements in the fields of dental implant, this healing period is getting smaller and smaller. Immediate loading of dental implants is becoming a very popular procedure in the recent time. Hence, we retrospectively analyzed the various risk factors for the failure of delayed and immediate loaded dental implants. MATERIALS AND METHODS In the present study, retrospective analysis of all the patients was done who underwent dental implant surgeries either by immediate loading procedure or by delayed loading procedures. All the patients were divided broadly into two groups with one group containing patients in which delayed loaded dental implants were placed while other consisted of patients in whom immediate loaded dental implants were placed. All the patients in whom follow-up records were missing and who had past medical history of any systemic diseases were excluded from the present study. Evaluation of associated possible risk factors was done by classifying the predictable factors as primary and secondary factors. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Kaplan-Meier survival analyses and chi-square test were used for assessment of level of significance. RESULTS In delayed and immediate group of dental implants, mean age of the patients was 54.2 and 54.8 years respectively. Statistically significant results were obtained while comparing the clinical parameters of the dental implants in both the groups while demographic parameters showed nonsignificant correlation. CONCLUSION Significant higher risk of dental implant failure is associated with immediate loaded dental implants. Tobacco smoking, shorter implant size, and other risk factors play a significant role in predicting the success and failure of dental implants. CLINICAL SIGNIFICANCE Delayed loaded dental implant placement should be preferred as they are associated with decreased risk of implant failure.

Abstract
Objectives. The aim of the study was to evaluate and compare crestal bone loss of single-maxillary immediate postextractive implants and immediate nonfunctional loading (INFL) during 72 months of follow-up. Material and Methods. Two single titanium implants (Certain Prevail, Biomet 3I, USA) were placed in two patients using INFL technique. Implant stability and crestal bone level were measured on periapical radiographs at 1, 3, and 6 months after surgery. Results. All osseointegrated implants were clinically successful after 6 years of functional loading. Conclusion. Within the limit of the present case report, the paper supports the concept that INFL of single dental implant can be a successful treatment procedure.
