[PMID: 38360396 DOI: 10.1016/j.jdent.2024.104883] [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: 12/12/2023] [Revised: 02/05/2024] [Accepted: 02/06/2024] [Indexed: 02/17/2024] Open
Abstract
OBJECTIVES Recent literature suggests that the use of electronic cigarette (e-cigarette) is a substantial contributing factor to the unsuccessful outcomes of dental implant procedures. Our aim was to systematically review the effect of e-cigarette use on clinical (PI, PD, BOP), radiographic (bone loss), and immunologic (IL-1β) peri‑implant parameters. DATA Main search terms used in combination: electronic cigarette, peri‑implantitis, vaping. SOURCES An electronic search was undertaken for MEDLINE, EMBASE, COCHRANE, and SCOPUS databases between 2017 and 2023. STUDY SELECTION The study protocol was developed according to PRISMA guidelines, and the focus question was formulated according to the PICO strategy. No restriction was accepted regarding language or year to avoid selection bias; the initial database search yielded 49 publications. Following the selection process, only seven studies met the inclusion criteria. Seven studies were statistically analyzed via MedCalc program. A pooled effect was deemed statistically significant if the p-value was less than 0.05. CONCLUSION Electronic cigarettes cause an increase in probing depth, bone loss, and the level of IL-1β, one of the bone destruction mediators in the tissues around the implant, and a decrease in bleeding on probing. CLINICAL SIGNIFICANCE E-cigarette is a potential risk factor for the healing process and the results of implant treatment, similar to cigarettes. Performing clinical research to evaluate the e-cigarette effect on peri‑implantitis in an age and gender-match population is needed.

Abstract
OBJECTIVES To analyze the effect of COVID-19 on early implant failures and identify potential risk factors for early implant failure, concerning patient- and implant-related factors. MATERIALS AND METHODS This retrospective study is based on 1228 patients who received 4841 implants between March 11, 2020, and April 01, 2022, at Erciyes University Faculty of Dentistry. COVID-19, age and gender of patients, smoking, diabetes, irradiation, chemotherapy, osteoporosis, the implant system, location, and characteristics of implants were recorded. At the implant level, univariate and multivariate generalized estimating equation (GEE) logistic regression was used to examine the effect of explanatory variables on early implant failure. RESULTS The early implant failure rate was 3.1% at the implant level and 10.4% at the patient level. Smokers showed a significantly higher incidence of early implant failures compared to nonsmokers. (odds ratio (OR; 95% CI): 2.140 (1.438-3.184); p < 0.001). Short implants (≤8 mm) had a higher risk of early implant failure than long implants (≥12 mm) (OR (95% CI): 2.089 (1.290-3.382); p = 0.003). CONCLUSIONS COVID-19 had no significant effect on early implant failure. Smoking and short implants were associated with a higher risk for early implant failures.

Abstract
OBJECTIVE The success of dental implants is determined by the osteointegration process. Many studies state that smoking cigarettes can inhibit osseointegration, but the inhibition mechanism is still unclear.The aim of this study was to identify and analyze the effect of nicotine on the inhibition of dental implant osseointegration through the expression of nicotinic acetylcholine receptor (nAChR), nuclear factor of activated T cells cytoplasmic 1 (NFATc1), osteoclast, and osteoblast numbers. MATERIALS AND METHODS This study is an experimental study of 16 New Zealand rabbits, randomized across two groups. Group 1 (eight rabbits) was a control group, and group 2 (eight rabbits) was a treatment group. The treatment group was given 2.5 mg/kg body weight/day of nicotine by injection 1 week before placement of the implant until the end of research. Observations were made in the first and the eighth week by measuring the number of osteoblast and osteoclast by immunohistology test and the expression of nAChR and NFATc1 by immunohistochemistry test. STATISTICAL ANALYSIS Data was analyzed using a one-way analysis of variance and Student's t-test. A p-value of < 0.05 was considered statistically significant. RESULTS Significant differences were found between the control and treatment groups (p < 0.05). Results showed that nicotine increases the expression of nAChR and decreases the number of osteoblasts and the expression of BMP2 and osteocalcin. CONCLUSION Nicotine inhibits the osseointegration of dental implants by increasing nAChR, NFATc1, osteoclast numbers, and decreasing osteoblast numbers.

Abstract
OBJECTIVE The aim of this study was to systematically analyze the influence of smoking on the incidence of peri-implantitis. MATERIALS AND METHODS The search was performed in the National Library of Medicine (MEDLINE-PubMed), SCOPUS, EMBASE, and ISI Web of Science databases (finished on November 30, 2022). Systematic review and meta-analysis were conducted according to PRISMA statement. Prospective cohort studies that evaluate the incidence of peri-implantitis in smokers and non-smokers were included. Two authors independently searched for eligible studies, screened titles, and abstracts, did the full-text analysis, extracted data, and performed the risk-of-bias assessment. The results were summarized through random-effects meta-analyses. The GRADE method was used to determine the certainty of evidence. RESULTS A total of 7 studies with 702 patients and 1959 implants were included for analysis. The meta-analysis revealed a significant difference between smokers and non-smokers for the risk of peri-implantitis in the implant-based (p < .0001) and patient-based analysis (p = .003). A strong association between smoking and the risk for peri-implantitis was verified at the implant level (RR: 2.04, 95% CI: 1.46-1.85) and the patient level (RR: 2.79, 95% CI: 1.42-5.50). CONCLUSIONS Moderate certainty evidence suggests that smoking is associated with peri-implantitis compared to non-smoking at the patient and implant levels.

Acta Biomater 2022; 154:302-311. [PMID: 36306984 DOI: 10.1016/j.actbio.2022.10.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Revised: 09/21/2022] [Accepted: 10/19/2022] [Indexed: 01/24/2023]
Abstract
Dental implant stability is greatly affected by the mechanical properties of the bone-implant interface (BII), and it is key to long-term successful osseointegration. Implant stability is often evaluated using the Resonant Frequency Analysis (RFA) method, and also by the quality of this interface, namely the bone-implant contact (BIC). True to this day, there is a scarcity of models tying BIC, RFA and a spatially and mechanically evolving BII. In this paper, based on the contact/distance osteogenesis concept, a novel numerical spatio-temporal model of the implant, surrounding bone and evolving interface, was developed to assess the evolution of the interfacial stresses on the one hand and the corresponding resonant frequencies on the other. We postulate that, since the BIC percentage reaches saturation over a very short time, long before densification of the interface, it becomes irrelevant as to load transmission between the implant and the bone due to the existence of an open gap. Gap closure is the factor that provides continuity between the implant and the surrounding bone. The results of the calculated RFA evolution match and provide an explanation for the multiple clinical observations of a sharp initial decline in RFA, followed by a gradual increase and plateau formation. STATEMENT OF SIGNIFICANCE: A novel three-dimensional numerical model of an evolving bone-dental implant interface (BII) is presented. The spatio-temporal evolution of the bone-implant contact (BIC) and the BII, based on contact/distance (CO/DO) osteogenesis, is modeled. A central outcome is that, until BII maturation into a solid continuous bone (no open gap between CO-DO fronts), the bone-implant load transfer is hampered, irrespective of the BIC. The resonant frequencies' evolution of the jawbone-BII-implant is calculated to reproduce the well-established implant stability analysis based on the Resonant Frequency Analysis. The results resemble those reported clinically, and here too, the determinant transition occurs only after interfacial gap closure. Those results should motivate clinicians to re-consider structural continuity of the BII rather than the BIC only.

Abstract
We aimed to examine the implant stability quotient (ISQ), alveolar bone level measurements (ABL), and bone alkaline phosphatase (BALP) in peri-implant crevicular fluid (PICF) around implants in smokers and non-smokers before loading in 3 months. 44 dental implants were placed into smoker and non-smoker patients equally. ISQ was measured at baseline and 3 months after surgery. The levels of PICF BALP and alveolar bone were measured. ISQ values significantly increased in smokers and non-smokers in the 3rd month (p < 0.05). ABL measurements were lower at 3 months compared to baseline in both groups (p < 0.05). Although ISQ and ABL values were higher in non-smokers than smokers at 3 months, the difference between the groups did not show any statistical significance. The PICF BALP levels in the 3rd month changed in both groups. But, these differences were insignificant. Although some of the measurements presented differences between the groups during the assessment periods, they were not indicative of the hazardous effects of smoking on bone healing around implants after surgery till functional loading in 3 months. However, smoking is an important factor to be considered for osseo-integration outcomes. Further studies are needed to clarify the influence of smoking on osseo-integration.

Abstract
PURPOSE This study aimed to evaluate the effectiveness of the partial split-flap technique with a K-incision on vertical guided bone regeneration (vGBR) and to retrospectively analyze the clinical and radiographic outcomes of dental implantation using this approach. METHODS In total, 78 patients who received 104 dental implants with vGBR, categorized as (1) pre-GBR and post-implantation and (2) simultaneous GBR and implantation, were enrolled. Data analysis was based on periapical radiographs, clinical photos, and dental records. The 2-sample t-test was used to compare the 2 surgical procedures. RESULTS The baseline vertical bone level, augmented bone height (ABH), and treatment duration were significantly higher in the pre-GBR procedure group. The survival rates of the implants were 96.1% and 94.8% in implant- and patient-based analyses, respectively. In Cox regression analysis, high rates of implant failure were found in the presence of ABH of ≥4 mm, smoking, and diabetes. CONCLUSIONS Within the limitations of this retrospective study, the partial split-flap technique using a K-incision for vGBR showed stable clinical outcomes and favorable dental implant survival.

Abstract
Background: Smoking tobacco significantly affects the biology of periodontal tissues and contributes to the increased risk of peri-implant diseases. The aim of the study was to investigate whether smoking cigarettes affects the primary and secondary stability of maxillary dental implants, inserted into fresh sockets immediately after extraction. Methods: The study was conducted on 164 patients between the ages of 27–71 years old. 67 individuals smoked more than 20 cigarettes daily and 97 were non-smokers. 190 immediate implants were inserted in the maxilla. Immediate implantations were performed with simultaneous augmentation of the socket with xenogenic bone grafting material. In the posterior region, implants were inserted into the palatal alveolus. The stability of the implants was measured using Insertion Torque Value (ITV) and two types of devices: Periotest (PT) and Osstell (ISQ). Marginal bone loss was evaluated on cone beam computed tomography scans. Results: In an aesthetic area, the PT values at 6 months post-implantation were higher for smokers than non-smokers (p < 0.05), respectively. The ISQ values were significantly lower in smokers compared to non-smokers at 6 months post-implantation (p = 0.0226), respectively. In the posterior region PT values were higher in smokers both on the day of implantation (p = 0.0179), 6 months after surgery (p = 0.0003) as well as 24 months after surgery (p < 0.0001), as compared to non-smokers, respectively. Smokers revealed lower ISQ values than non-smokers (p = 0.0047) on the day of implantation, as well as 6 months after implantation (p = 0.0002), respectively. There were no significant differences in marginal bone loss after 18 months of loading between smokers and non-smokers in the aesthetic, as well as posterior regions (p > 0.05). ITV measurements were lower in smokers than non-smokers in the aesthetic (16.3 vs. 17.5 Ncm) and posterior area (16.8 vs. 17.9 Ncm). Conclusions: This study indicate that smoking cigarettes has a negative effect on the stability of immediate implants in the maxilla. Primary stability of immediate implants may be lower in the posterior area of the maxilla in smokers when compared to non-smokers, which may eliminate smokers from immediate implants in this region. Secondary stability of immediate implants may be lower in both the aesthetic and posterior areas in smokers compared to non-smokers, which may encourage the postponement of final crowns delivery at 6 months post op and the extension of the occlusaly temporary crowns use in some smoker cases.

Abstract
BACKGROUND What impact does tobacco smoking have on photodynamic therapy (PDT) outcome is still unknown. The aim of the present clinical trial was to evaluate the clinical, radiographic, and biological bone markers after provision of PDT in cigarette, e-cigarette, and never-smokers with peri-implantitis (PI) at 6 months post treatment. MATERIALS AND METHODS Twenty-five healthy patients with PI were divided into three groups: Group I: cigarette smokers; Group II: e-cigarettes users; Group III: never-smokers. Full-mouth mechanical debridement with adjunctive methylene blue-mediated PDT was performed. Clinical recordings included peri-implant plaque index (Pi), bleeding on probing (BOP) and probing depth (PD). Peri-implant sulcular fluid was collected for the assessment of biological bone biomarkers including receptor activator of nuclear factor-ligand (RANK-L) and osteoprotegrin (OPG). All assessments were performed at baseline, 3 months and 6 months. P-value of <0.05 was considered significant. RESULTS BOP in Group II and III significantly reduced at 3 months (p < 0.05). Group I showed significant reduction only at 6 months (p < 0.05). Mean PD showed no statistically significant difference between the groups at any time-point. Inter-group comparison showed Group III demonstrating statistically significantly reduced mean RANK-L levels at both 3 and 6 months (p < 0.05). A slight increase in the OPG levels were observed at 3 months and followed by a slight decrease at 6 months for all the study groups when compared with baseline values, however, these values did not show statistical significance (p > 0.05). CONCLUSION Adjunctive PDT helped in reducing the clinical peri-implant inflammation. However, no significant change was observed for biological bone biomarkers among tobacco smokers.

Abstract
Object. The article presents an assessment of the effect of smoking on factors of non-specific resistance of oral mucosa by the reaction of adsorption of microorganisms by epithelial cells.
Purpose. is to detect and evaluate changes in non-specific oral mucosa resistance in smoking patients.
Methodology. A clinical examination of the oral cavity 120 volunteers (58 women and 62 men) aged 18 to 44 years (average age: 22, 50 ± 2.59) was conducted. Three groups 2 participants have been formed: the main group (75 people) ― smokers and the comparison group (45 people) - non-smoking volunteers.
The material taken twice: in smokers - before and 15 minutes after smoking, in non-smokers (for reliability) ― initially and after 15 minutes. A sterile instrument used to cut epithelium off the mucosa portion of the inner surface of the cheek, transfer it to a slide, dry, stain and microscopy the preparations. The integrity of the epithelial cell structure, their size, the intensity of the core staining and the cytoplasm evaluated. Depending on the number of microorganisms adsorbed on their surface, the viewed epithelial cells divided into 4 categories.
Results. A change in the adsorption response of microorganisms by epithelial cells indicates a negative influence of tobacco on the oral mucosa.
Conclusions. Smoking negatively affects the state of local immunity ― non-specific resistance of oral mucosa. Changes in the adsorption response of microorganisms by oral mucosa epithelial cells can be used in the diagnosis and prevention of diseases of oral organs arising from smoking.

Abstract
Subject. Tobacco smoking is a common bad habit in the world. The problem of smoking affects not only social, but also medical, including dental, aspects. The irritating effect of nicotine on the oral mucosa and salivary glands leads to the development of stomatitis, xerostomia and halitosis. Prevention of diseases of the oral cavity of smokers has its own characteristics in connection with changes in plaque and oral fluid. The article presents the experience of rapid diagnostics of the negative effects of smoking as a controlled process in the practice of a dentist.
The aim is to evaluate the effectiveness of rapid diagnosis in chronic smokers based on a statistical analysis of the type of microcrystallization of mixed saliva (CC).
Methodology. A clinical examination of the oral cavity of 120 volunteers (58 women and 62 men) aged 18 to 44 years (average age — 22.50 ± 2.59 years) was conducted. The main group of smokers included 75 people, the comparison group (non-smoking volunteers) — 45. SS sampling and statistical analysis of microcrystallization types in smokers and non-smokers were performed twice: before and 15 minutes after smoking.
Results. The appearance of pathological morphotypes of microcrystallization SS indicates the negative effect of tobacco smoking on oral fluid. Data were obtained on the deterioration of the function of saliva in smokers, which creates the conditions for enhancing pathological processes in the oral cavity.
Conclusions. Smoking negatively affects the morphological picture — the microcrystalline structure of the SS. Structural changes in crystallized SS can serve as diagnostic signs of diseases and can be used in the diagnosis and prevention of diseases of the oral organs during smoking.

Abstract
INTRODUCTION Periodontal disease and oral cancer are common health hazards. Epidemiological investigations show that smoking, periodontal disease and oral cancer are closely related. Tobacco is one of the major risk factors for periodontitis and oral cancer. METHODS A systematic literature review was performed. To identify relevant studies, the following online databases were searched using specific keywords: PubMed, Web of Science and CNKI. RESULTS Tobacco not only possesses an addictive effect, but it aggravates periodontal disease by promoting the invasion of pathogenic bacteria, inhibiting autoimmune defense, aggravating the inflammatory reaction, and aggravating the loss of alveolar bone. According to current evidence, tobacco significantly aggravates the development and progression of periodontal disease and oral cancer, and periodontal disease may be related to the prevalence of oral cancer. CONCLUSIONS Clinicians should strongly recommend that smokers undertake a strategy to stop smoking to avoid the exacerbation of nicotine-related periodontal disease and to reduce the incidence of oral cancer.

Cigarette Smoke Extract Exposure: Effects on the Interactions between Titanium Surface and Osteoblasts. BIOMED RESEARCH INTERNATIONAL 2019; 2019:8759568. [PMID: 31143776 PMCID: PMC6501272 DOI: 10.1155/2019/8759568] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Revised: 03/22/2019] [Accepted: 04/08/2019] [Indexed: 11/18/2022]
Abstract
The aim of this study was to explore the changes in the characteristics of titanium surface and the osteoblast-titanium interactions under cigarette smoke extract (CSE) exposure. In this study, CSE was used to simulate the oral liquid environment around the implant under cigarette smoke exposure. Titanium samples were immersed in CSE to explore the changes in the characteristics of titanium surface. The physical properties of titanium surface were measured, including surface micromorphology, surface elemental composition, roughness, and surface hydrophilicity. MC3T3-E1 cells were cultured on the titanium surface in vitro under different concentrations of CSE exposure, and cell adhesion, cell proliferation, and osteogenic differentiation were observed. The surface micromorphology and elemental composition of titanium surface changed under CSE exposure. No obvious changes were found in the surface roughness and the hydrophilicity of titanium samples. Moreover, the results of in vitro study showed that CSE exposure downregulated the cell spreading, proliferation, and osteogenic differentiation of MC3T3-E1 cells on the titanium surface. It could be speculated that some carbon-containing compounds from CSE adsorbed on the titanium surface and the osteoblast-titanium interactions were influenced under CSE exposure. It is hoped that these results could provide valuable information for further studies on smoking-mediated inhibition of implants osseointegration.

Akram Z, Javed F, Vohra F. Effect of waterpipe smoking on peri-implant health: A systematic review and meta-analysis. ACTA ACUST UNITED AC 2019; 10:e12403. [PMID: 30834712 DOI: 10.1111/jicd.12403] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2018] [Revised: 12/15/2018] [Accepted: 12/20/2018] [Indexed: 01/11/2023]
Abstract
The aim of the present review was to evaluate the effect of waterpipe smoking (WS) on clinical peri-implant inflammatory parameters compared to non-smokers (NS) with dental implants. Literature searches were performed using bibliographic databases up to May 2018. Primary outcomes included peri-implant bone loss (PIBL), while secondary outcomes were probing depth (PD), plaque index, and bleeding on probing. Relative risk (RR) and 95% confidence intervals (CI) for each PIBL and PD were estimated by a random-effect model. Four retrospective case-control studies were included in the qualitative and quantitative syntheses. All of the included studies showed statistically-significantly worse peri-implant outcomes in WS compared to NS. Considering the effects of WS on peri-implant parameters, significant heterogeneity for PIBL (Q-value = 34.21, P < 0.0001, I2 = 94.16%) and PD (Q-value = 51.97, P < 0.0001, I2 = 96.15%) was observed between both groups. The overall RR for PIBL (RR = 3.32, 95% CI = 1.01-3.97, P = 0.001) and PD (RR = 3.40, 95% CI = 1.91-7.17, P = 0.001) were significant between WS and NS groups. WS has detrimental effect on peri-implant health. Clinicians should instruct and advise patients about poor prognosis and peri-implant diseases caused by WS.

Abstract
The aim of the study was determination of the effectiveness of peri-implantation zone tissues control by means of cytomorphometry in cellular imprints obtained from the area of dental implantation on a model applying a comparison of the state of the tissues of the peri-implantation zone of smokers and non-smokers. MATERIAL AND METHODS: Cytomorphometry was used for tissue monitoring in implant-adjacent areas by the Index of Destruction (ID) and the Inflammatory-Destructive Index (IDI) in the group of smoking patients: 6 females and 9 males (41 implant) and in the group of non-smoking patients: 13 females and 14 males (97 implants). Follow-up terms in both groups from the moment of gingival former or provisional crown placement comprised 1, 5, 15, 25, 30, 60, 120, 180, 240, 720 days. Significant increase of ID within 25-120 days was revealed in smokers. The study of Inflammation-Distraction Indices revealed a statistically significant increase in the values in group of smokers at 5 to 60 days. The results of using of cytomorphometric method allow conclude that smoking is a pathogenic factor that exerts its influence through initiation and sustentation of an inflammatory process in the tissues adjacent to dental implants.

[PMID: 30209875 DOI: 10.1111/cid.12664] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2018] [Revised: 07/13/2018] [Accepted: 07/21/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND To date, there has been no study identified that assessed peri-implant parameters and local levels of proinflammatory cytokines between waterpipe smokers (WS) and electronic cigarette users (VS). To evaluate the true effect of the risk indicator (WS and VS), a positive control (cigarette smokers [CS]) was added in the study design. PURPOSE To compare clinical and radiographic peri-implant parameters and proinflammatory cytokine profile in the peri-implant sulcular fluid (PISF) among CS, WS, VS, and nonsmokers (NS). MATERIALS AND METHODS Forty CS, WS, VS, and NS were included. Details regarding demographics, duration of implants, and habits were recorded. Clinical examination for periodontal and peri-implant plaque index (PI), bleeding on probing (BOP), and probing depth (PD ≥ 4 mm) were assessed. Radiographic bone loss (RBL) was assessed using digital periapical radiographs and viewed on a calibrated computer screen using an image analyzer. Levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL)-6, and IL-1β in PISF were evaluated using enzyme-linked immunosorbent assay. RESULTS Mean peri-implant PI (P < .05), PD ≥ 4 mm (P < .05), and total RBL (P < .01) was significantly higher among CS, WS, and VS compared with NS. Statistical differences in BOP were observed in NS (P < .01) compared to CS, WS, and VS. CS and WS showed significantly higher PD ≥ 4 mm and RBL compared with VS (P < .05). Levels of TNF-α, IL-6, and IL-1β were significantly higher in CS, WS, and VS compared to NS. There were no statistical differences in the mean levels of all proinflammatory cytokines among individuals in CS and WS. CONCLUSION Tobacco smoking is associated with poor peri-implant health. The effect of waterpipe smoking was of largely the same extent as that of cigarette smoking. Higher levels of inflammatory cytokines in tobacco smokers may propose increased peri-implant inflammatory process which could play a principal role in the progression of peri-implant tissue damage.

Abstract
Tobacco smokers have slowed bone growth and regeneration and more frequent implant failures than non-smokers, but the effect of cigarette smoking on the host response to bone-dwelling biomaterials is poorly understood. Macrophages and mesenchymal stem cells (MSCs) are essential in the healing response after implant placement. This study examined the effects of an experimental model of cigarette smoke exposure using cigarette smoke extract (CSE) on bone architecture in vivo and differentiation and inflammatory cytokine production on clinically relevant microstructured surfaces in vitro. CSE was prepared by bubbling mainstream smoke from one research cigarette (3R4F) in 1 mL phosphate-buffered saline. For in vivo studies, bone morphometry was examined in femurs isolated from mice injected with diluted CSE for 25 days. For in vitro studies, osteogenic markers and interleukins were measured in human MSCs and murine macrophages cultured on rough or rough-hydrophilic titanium (Ti) surfaces in culture media ± CSE for seven days. In vivo, CSE exposure decreased in bone area, volume, and interconnectivity in a dose-dependent manner. In vitro, macrophages exposed to CSE increased production of pro-inflammatory cytokines, abolishing the increase in anti-inflammatory cytokines typically seen on rough-hydrophilic surfaces. MSCs exposed to CSE had lower mRNA expression of osteoblast differentiation markers, increased levels of pro-inflammatory mRNA, and reduced production of osteogenic proteins. Our results demonstrate that CSE decreases osteogenic differentiation and anti-inflammatory interleukin production while increasing pro-inflammatory interleukin production in macrophages and MSCs, suggesting that compounds in CSE strongly affect stem cell differentiation and may compromise bone formation following biomaterial placement. STATEMENT OF SIGNIFICANCE The study of implantable materials' interaction with biological systems occurs nearly exclusively in healthy cell and animal models. However, 15% of the US population smokes cigarettes, which is known to modulate immune response and tissue regeneration. To explore this interaction, we created a method of capturing smoke compounds as CSE for in vivo and in vitro use. We found chronic injection into mice produced an osteoporotic, pro-inflammatory phenotype similar to direct smoke models. Furthermore, CSE attenuated osteogenic differentiation and promoted a pro-inflammatory profile in MSCs and macrophages, respectively, when cultured on titanium surfaces. These results demonstrate that this CSE model may be useful for predicting how chronic tobacco exposure may adversely affect the outcome of biomedical implants in pre-clinical models.

Abstract
This systematic review explored associations between smoking and health outcomes involving the musculoskeletal system. AMSTAR criteria were followed. A comprehensive search of PubMed, Web of Science, and Science Direct returned 243 articles meeting inclusion criteria. A majority of studies found smoking has negative effects on the musculoskeletal system. In research on bones, smoking was associated with lower BMD, increased fracture risk, periodontitis, alveolar bone loss, and dental implant failure. In research on joints, smoking was associated with increased joint disease activity, poor functional outcomes, and poor therapeutic response. There was also evidence of adverse effects on muscles, tendons, cartilage, and ligaments. There were few studies on the musculoskeletal health outcomes of secondhand smoke, smoking cessation, or other modes of smoking, such as waterpipes or electronic cigarettes. This review found evidence that suggests tobacco smoking has negative effects on the health outcomes of the musculoskeletal system. There is a need for further research to understand mechanisms of action for the effects of smoking on the musculoskeletal system and to increase awareness of healthcare providers and community members of the adverse effects of smoking on the musculoskeletal system.

Abstract
The aim of this study was to compare the 5-year outcome of full-arch mandibular fixed prosthetic rehabilitation using the All-on-4 concept in smoking and nonsmoking patients. This retrospective cohort study included 200 patients (n = 100 smokers, n = 100 nonsmokers), 119 women and 81 men, with an average age of 53.7 years, rehabilitated in immediate function with 800 implants. Implant cumulative survival rate estimation (Kaplan-Meier with log-rank test) and marginal bone resorption (MBR) at 5 years (Mann-Whitney test) were compared between both groups. Multivariable analysis was used to investigate potential risk indicators for MBR ≥ 2.8 mm at 5 years. Nine patients (4.5%) were lost to follow-up. Four patients lost eight implants, specifically one nonsmoking patient (n = 1 implant) and three smoking patients (n = 7 implants), resulting in a cumulative survival rate estimation of 99.0% and 96.9% for nonsmokers and smokers, respectively (P = 0.296). The average (standard deviation) MBR at 5 years was 1.68 mm (0.76 mm) and 1.98 mm (1.02 mm) for nonsmokers and smokers, respectively (P = 0.045). Smoking (odds ratio = 2.92) was the only risk indicator significantly associated with MBR ≥ 2.8 mm in multivariable analysis. Smoking should not be an absolute contraindication for rehabilitation of the edentulous mandible through the All-on-4 concept; however, smoking habits were significantly associated with MBR ≥ 2.8 mm.

Abstract
The direct attachment of the osseointegrated prosthesis to the skeleton avoids the inherent problems of socket suspension. It also permits physiological weight bearing, improved range of motion in the proximal joint, and osseoperceptive sensor feedback, enabling better control of the artificial limb by amputees. This article describes the osseointegration program in Sweden based on the use of bone-anchored prostheses for transfemoral amputation rehabilitation. The authors discuss in detail the patient-centered evaluation, surgical technique, and postoperative rehabilitation protocol. The outcomes of a prospective study of transfemoral amputees using the bone-anchored prostheses are presented. [Orthopedics. 2018; 41(2):75-80.].

Abstract
Implant-supported overdentures are becoming the treatment of choice for the completely edentulous mandible. They significantly improve the quality of life in edentulous patients. For this review article, the literature was searched to identify pertinent studies. No meta-analysis was conducted because of high heterogeneity within the literature. Accordingly, in this review article, the author provides an update on implant-supported mandible overdentures with regard to the number of implants, type of loading, stress-strain distribution, mode of implant-to-denture attachment, occlusal considerations and complications.

Abstract
OBJECTIVE To investigate the outcomes of implant therapy in partially dentate patients treated for aggressive periodontitis (GAgP) in comparison to periodontally healthy (HP) and patients treated for chronic periodontitis (CP) utilizing radiographic and clinical parameters. MATERIAL AND METHODS An electronic search of databases, supplemented by hand searching, was conducted to identify relevant clinical studies. Sequential screenings at the title, abstract and full-text levels were performed independently and in duplicate. A random effects meta-analysis was conducted and bias corrected bootstrap 95 % confidence intervals were estimated for group comparisons. RESULTS The search strategy revealed a total of 899 results. After title screening, abstract scanning, and full-text reading, seven articles fulfilled the inclusion criteria. The 3-year survival rate for CP and HP patients was 100 % while in GAgP subjects, the respective value was 97.98 %; this difference being statistically significant. The 3-year mean marginal bone loss (MBL) was 1.07 mm for the GAgP group, 0.47 mm for the CP group, and 0.69 mm for the HP group. A significant difference between the GAgP and CP groups was identified (p < 0.05). The weighted mean differences of MBL concerning the above groups were also calculated and examined for statistical significance in both 1 and 3 years. CONCLUSIONS The 3-year survival rate and peri-implant marginal bone loss was found statistically significantly lower in GAgP subjects (SR 97.98 % vs 100 %) in comparison to HP and CP individuals. CLINICAL RELEVANCE The outcome of implant therapy in terms of survival rate and marginal bone loss is considered very important for the clinician in decision making when placing implants in patients with a history of aggressive periodontitis.

Abstract
OBJECTIVES The objectives of this study were to identify risk factors associated with the premature cover screw exposure (pCSE) at dental implants and to evaluate the influence of a pCSE on peri-implant marginal bone level (MBL) change compared to non-exposed implants. MATERIALS AND METHODS Retrospective data assessment from 165 patients (mean age = 54.0 ± 14.4 years) who received 395 submerged implants included demographic, health-related, and therapeutic variables which were analyzed for their respective impact. MBL change was detected at digital radiographs obtained from first- and second-stage surgeries. RESULTS pCSE were detected in 43 patients (26.1%) and 53 implants (13.4%). An increased frequency of exposure was significantly associated with (I) male gender (p = 0.012) at patient level and (II) the posterior region of the jaws (p = 0.005), implant systems with platform-matching cover screws, and a vertical distance of ≥0.5 mm between bone crest and the implant platform (both p < 0.001) at implant level. The decrease in mesial, distal, and total MBL differed significantly (mean total = 0.8 ± 0.7 vs. 0.3 ± 0.5; mean mesial = 0.8 ± 0.8 vs. 0.3 ± 0.6; mean distal = 0.8 ± 0.8 vs. 0.3 ± 0.6 mm; p < 0.001) between non-exposed and pCSE implants. CONCLUSIONS Male patients, implants with platform-matched cover screws, or when placed supracrestally or in posterior sites revealed significantly more pCSE, resulting in significantly decreased peri-implant MBL compared with non-exposed implants. CLINICAL RELEVANCE Patients with an enhanced risk of pCSE should follow frequent regular recalls during the healing period to enable for early diagnosis and intervention.
