The Influence of Immediately Loaded Basal Implant Treatment on Patient Satisfaction

Esthetic Rehabilitation of a Young Patient With Immediately Loaded Single-Piece Basal Implants Following a Trauma Involving the Anterior Maxilla: Case Report With Five-Year Follow-Up

Traumatic injuries to the anterior maxilla usually lead to loss of teeth by means of avulsion or extraction due to fracture. Rehabilitation of such a clinical scenario is complex as it involves various anatomic and esthetic challenges. Single-piece basal implants have been widely used in the rehabilitation of resorbed ridges because they gain adequate anchorage from the basal cortical bone, allowing immediate temporization or loading. However, the use of basal implants in the anterior esthetic zone is not much documented. This case report with a five-year follow-up period describes the rehabilitation of lost teeth in the anterior esthetic zone of the anterior maxilla caused due to trauma following a train accident using single-piece axial basal implants with immediate temporization.

Does the Protrusion of Corticobasal Implants in the Maxillary Sinuses Affect Sinus Health? A Retrospective Study

AIM

The aim of this retrospective study is to investigate the effect of corticobasal implant penetration in the nasal and maxillary sinuses on sinus health and implant survival rate in cases of severely atrophid ridges.

MATERIALS AND METHODS

This retrospective study was conducted on thirty patients with 172 implants who underwent corticobasal implant treatment between 2014 and 2018. Implants were divided into two groups according to the penetration depths (Group A, <4 mm; Group B, 4 mm). Inclusion criteria for the study included: (A) patients with severe maxillary ridge resorption with an immediately loaded corticobasal implant-supported prosthesis that showed implant protrusion inside the maxillary sinus on cone-beam computed tomography (CBCT); and (B) patients with a preoperative and postoperative follow-up CBCT scan using the same standard technique and machine. (C) Patients without any history of sinusitis before implant insertion patients who fulfilled the inclusion criteria were recalled for follow-up. The presence of sinus complications was clinically assessed according to the clinical practice guidelines for adult sinusitis of the American Academy of Otolaryngology-Head and Neck Surgery and Radiologically using CBCT. Moreover, patient satisfaction was evaluated using yes-or-no questions. The result was statistically analyzed using Fisher's Exact test.

RESULTS

Despite the differences in implant penetration depths, no clinical signs of sinusitis were evident in any patient. One patient presented with transient epistaxis after the surgery, and 2 patients with nine implants revealed nonsignificant thickening of the sinus membrane radiologically (p = 0.055). All implants showed optimum bone-implant contact with a 100% survival rate. A significant relationship was reported between the thickness of the membrane and the patient's gender, hypertension, and smoking habits. (p = 0.001*, p = 0.002*, and p = 0.034*, respectively).

CONCLUSION

Penetration of corticobasal implants in the maxillary sinus did not compromise the health of the maxillary sinus or implant survival rate.

CLINICAL SIGNIFICANCE

Limited posterior maxillary bony support and maxillary sinus pneumatization present challenges in implant dentistry and increase the possibility of implant protrusion inside the maxillary and nasal cavities. Hence, studying the effect of this protrusion on the maxillary sinuses' health and implant survival is highly significant.

Single Tooth Replacement Using Immediately Loaded Basal Implant-Supported Fixed Prosthesis in a Hyperdense Lesion: A Case Report

Osseous modifications in the periapical areas are related to chronic endodontic infections. Often, teeth with periapical infections and hopeless prognosis are removed and replaced with dental implants. In this clinical report, a patient with a radiopaque lesion on the root apex of the mandibular right first molar root is presented. Bone- and tissue-borne lesions were the differential diagnoses for the radiopaque mass. Based on the clinical and radiological characteristics, condensing osteitis (CO) was the final diagnosis of osseous growth (bone density and trabeculation of the bone). Under local anesthesia, tooth 46 was atraumatically extracted, and the immediate basal implant was placed. This case report investigated the effectiveness and safety of dental implantation in the vicinity of hyperdense lesions.

Solid PRF Serves as Basis for Guided Open Wound Healing of the Ridge after Tooth Extraction by Accelerating the Wound Healing Time Course-A Prospective Parallel Arm Randomized Controlled Single Blind Trial

Systematic evaluations regarding the influence of PRF in ridge sealing are still lacking. To the best of our knowledge, this is the first systemic randomized, controlled, clinical approach dealing with the potential of a systematic applied solid PRF on soft tissue socket healing of molar and premolar extraction sockets with evaluation for up to 90 days. Qualitative and quantitative image analysis showed that PRF contributed to a significantly faster ridge sealing, within the period of 7-10 days in both tooth types. This led to a visibly less contraction at the PRF-treated group sites at day 90. Patients' pain perception demonstrated no statistic significance between both groups (PRF vs. natural healing), but the patients in PRF group seemed to have had less pain throughout the observational period. It becomes evident that PRF is able to serve as a promotor of the secondary wound healing cascade. The guiding capacity of PRF accelerating the process of open ridge healing makes it possible to act as a natural growth factor drug delivery system, providing a more predictable guided open wound healing of the ridge with less contraction of the soft tissue, the latter being a key factor for the subsequent successful dental implantation and oral rehabilitation.

Rehabilitation of Patients with Compromised Ridge Support Using Immediately Loaded Corticobasal Implant-supported Prostheses: A Prospective Observational Study

AIM

The aim of this prospective study is to evaluate the treatment outcomes and patient satisfaction following the use of fixed immediately loaded corticobasal implant-supported prostheses.

MATERIALS AND METHODS

One hundred and seventy-four corticobasal implants (basal cortical screw, BCS implant design) were inserted in 20 consecutive patients with compromised ridge support. Implant survival and success were assessed using the James-Misch implant health quality scale and the Albrektsson criteria for implant success. The peri-implant health was evaluated at 1 week and 3, 6, 9, 12, and 18 months postoperatively. Moreover, the radiographic and prosthetic parameters and patient satisfaction were assessed.

RESULTS

The implants showed optimum implant health and a 100% survival rate with none (0%) of the implants failing, mobile, lost, or fractured. Using Wilcoxon signed-rank test, significant decreases in both the modified gingival indexes and the probable pocket depth (PPD) and slight significant increases in the plaque index (PI) at 3, 9, 12, and 18 months and a nonsignificant increase at 6-month follow-up were reported with a range of 0-1. The calculus index (CI) was zero at all follow-up visits. Radiographic evaluations revealed increases in the bone-to-implant contact. Evaluation of the prostheses showed some treatable complications, and all the patients were satisfied.

CONCLUSION

The use of corticobasal implant-supported prosthesis meets the patient's demand for an immediate, fixed treatment modality, with high survival and success rates, optimum peri-implant soft tissue health, and high reported satisfaction.

CLINICAL SIGNIFICANCE

Corticobasal implants can improve the patient's esthetic, phonetic, mastication, and quality of life with the advantage of eliminating the need of bone grafting procedures.

Efficacy of platelet-rich fibrin in promoting the healing of extraction sockets: a systematic review

PURPOSE

To address the focused question: in patients with freshly extracted teeth, what is the efficacy of platelet-rich fibrin (PRF) in the prevention of pain and the regeneration of soft tissue and bone compared to the respective control without PRF treatment?

METHODS

After an electronic data search in PubMed database, the Web of Knowledge of Thomson Reuters and hand search in the relevant journals, a total of 20 randomized and/or controlled studies were included.

RESULTS

66.6% of the studies showed that PRF significantly reduced the postoperative pain, especially in the first 1-3 days after tooth extraction. Soft tissue healing was significantly improved in the group of PRF compared to the spontaneous wound healing after 1 week (75% of the evaluated studies). Dimensional bone loss was significantly lower in the PRF group compared to the spontaneous wound healing after 8-15 weeks but not after 6 months. Socket fill was in 85% of the studies significantly higher in the PRF group compared to the spontaneous wound healing.

CONCLUSIONS

Based on the analyzed studies, PRF is most effective in the early healing period of 2-3 months after tooth extraction. A longer healing period may not provide any benefits. The currently available data do not allow any statement regarding the long-term implant success in sockets treated with PRF or its combination with biomaterials. Due to the heterogeneity of the evaluated data no meta-analysis was performed.

Immediate rehabilitation of a rheumatoid arthritis patient with single-piece implants

INTRODUCTION AND IMPORTANCE

The aim of this article is to report the long-term outcome of full mouth rehabilitation with single piece, smooth surface implants following immediate loading protocol on a patient suffering with RA and severe unilateral condylar resorption.

CASE PRESENTATION

Here, we present a challenging case of a patient suffering from Rheumatoid Arthritis who was stabilized and completed successfully with a 4 year follow-up period. Prosthetic management optimized the inter-occlusal relationship to maintain both function and esthetic integrity. Single piece implants are designed to engage and take support from the cortical bone low in metabolic activities thus promoting the force transmission through apical threads that are engaged in the cortical bone.

DISCUSSION

Rheumatoid Arthritis [RA] is an auto-immune inflammatory condition in which the inflamed and hypertrophic synovial membrane grows into the articulation surfaces. The Temporomandibular Joints [TM] are frequently involved in rheumatoid arthritis. According to the literature on RA, due to frequent periodontitis, decreased salivary secretion, medication, as well as decrease in bone regenerative potential, RA is often considered as a relative contraindication in the use of implants. Atrophic jaws and cases with comorbidities like osteoporosis, diabetes, rheumatoid arthritis, periodontally infected cases are restored with high success by single piece smooth surface.

CONCLUSION

To the best of our knowledge, this may be the first case of immediate functional loading by bi-cortical single piece implants.

Immediate Prosthetic Rehabilitation of Marginal Mandibulectomy Post Radiation Case by Single-Piece Implant - A Case Report

Prosthetic rehabilitation post resection and radiotherapy demand a thorough understanding of the biomechanics of the jaw, its associated structures, and their post radiation changes at the bone level. Restoring lost structures can often pose a challenge, especially with regard to the dentition. Due to inadequate hard- and soft-tissue structures as well as their demand for “biologic osseointegration,” it is difficult to conduct immediate loading as a treatment option on conventional implants. Alternatives are today available. Since piece smooth surface cortical implants transmit occlusal forces at cortical bone/buttress by engaging them, with or without reliance on the alveolar bone, it can be considered as an option. Here, we report a case of immediate loading with single-piece smooth surface implants in a male patient who had undergone a marginal mandibulectomy 3 years back for the removal of an oral squamous cell carcinoma of the retromolar trigone area that was closed by an anastomosed radial forearm flap, followed by radiation therapy. The dentition was restored successfully using a single piece smooth surface cortically anchored implant and reported favorable success and survival rate with high patient acceptance. Single piece corticobasal implant technology is one of the most predictable methods for the functional and sociopsychological correction, with minimal invasive immediate functional loading protocol restoring function and post resection surgical deformation of the jaw, thus improving lifestyle and survival.
