Clinicoradiographic Evaluation of Long-term Efficacy and Risk Factors Associated with Dental Implants used for Full Mouth Rehabilitation.

Background: Despite various complications and failure factors, newer implants are designed that allow placement in sub-optimal conditions to allow the operator to place implants at sites with low bone quality. These newer designs also allow improved stability with higher survival rates in the short term. Aims: The present study was undertaken to evaluate long-term efficacy and risk factors associated with dental implant placement for full mouth rehabilitation. Materials and Methods: In 24 subjects, 438 implants were placed. The data collected were surgical and were retrospectively analyzed. The data collected included medical history, local, patient satisfaction, marginal bone loss, and systemic risk factors affecting implant survival. Outcome variables assessed were peri-implantitis, implant success, and survival at the follow-up visit. The data were expressed in terms of percentage and number, and the results were derived. Results: Peri-implantitis was seen in 31.05% (n = 136) of implants. 76.02% (n = 333) of implants were considered successful at recall. Concerning survival, compromised and satisfactory survival was shown by 10.04% (n = 44) and 2.96% (n = 13) of implants, respectively. 10.95% (n = 48) of implants were considered as failures. Conclusion: The present study concludes that good, long-term survival rates are associated with full mouth rehabilitation using dental implants.

Clinical Assessment of the Bone Width Following Lateral Ridge Expansion in Augmentation of Narrow Alveolar Ridges for Placing Immediate Dental Implants.

Background: Less residual alveolar bone at extraction site at esthetic and functional tooth position is the main limitation in placing a dental implant, especially at long-span edentulous ridges. This needs ridge augmentation. Aims: To assess bone width gain and implant stability following narrow ridge augmentation using the vertical ridge split technique. Materials and Methods: In 22 subjects within the age group of 20-60 years and the mean age of 38.46 years. The vertical ridge split technique was done in all subjects for horizontal ridge augmentation. Paraesthesia, pain/discomfort, mobility, and radiographic crestal bone width were assessed 6 months postoperatively. The data were described as mean and standard deviation along with number and percentage. Paired t-test was also used keeping the level of significance at P < 0.05. Results: Implant stability was seen in 86.36% (n = 19) study subjects and were not stable in 13.63% (n = 3) subjects. Bone width preoperatively was in the range of 3.1-4.4 mm with the mean value of 3.64 ± 0.41. Postoperatively, the bone width increased and was in the range of 5.2-6.3 mm with the mean value of 5.62 ± 0.45 mm. This increase postoperatively was statistically significant with a P value of <0.001. Conclusion: The present study concludes that acceptable success results are seen using the ridge split technique with simultaneous dental implants placement in both atrophic maxilla and mandible.

Benign fibrous histiocytoma of the maxilla: A rare case report and literature review.

Benign fibrous histiocytoma (FH) is a benign soft-tissue tumor that can present as a fibrous tissue mass anywhere in the body. The involvement of the paranasal sinuses is extremely rare, and very few cases have been reported in literature till date. We here report a case of benign FH localized in the maxillary sinus. The clinical and histological features of the lesion are discussed with a brief literature review of this pathology in the paranasal sinuses.

Comparative evaluation of efficacy of three treatment modalities - tetracycline fibers, scaling and root planing, and combination therapy: A clinical study.

BACKGROUND: Tetracycline is one of the primary antibiotics prescribed for antimicrobial therapy in periodontics. It has a broad spectrum of activity being effective against most bacteria as well as spirochetes. Due to limitations of systemic drug therapy, recent formulations of the drug for local administration in the subgingival area have been introduced, including collagen fibers impregnated with tetracycline. AIMS AND OBJECTIVE: To compare the effectiveness of tetracycline fibers alone or in combination with scaling and root planing (SRP) on clinical parameters in chronic periodontitis patients. MATERIALS AND METHODS: A total of twenty patients comprising of both sexes in the age group of 35-60 years with chronic periodontitis were selected. Split-mouth design was used, and three teeth from each patient with periodontal pocket measuring > 5 mm were selected which were treated with different treatment modality. They were randomly divided into site A (SRP), site B (tetracycline fibers only), and site C (combination therapy). Clinical parameters of plaque index (PI), gingival index (GI), pocket probing depth, and clinical attachment level (CAL) were recorded at 0, 30, and 45 days. The data obtained was compiled and put to statistical analysis. RESULTS: All the three groups showed improvement in PI, GI, probing pocket depth, and CAL. Results of the study showed greater improvements in clinical parameters in Group C compared to Group A and Group B. CONCLUSION: The results indicate that the adjunctive use of tetracycline fibers with SRP is a clinically effective and simple nonsurgical treatment method to improve periodontal health.

Clinical evaluation of hydroxyapatite and ß-tricalcium phosphate composite graft in the treatment of intrabony periodontal defect: A clinico-radiographic study.

BACKGROUND AND OBJECTIVE: Hydroxyapatite (HA) and ß-tricalcium phosphate (ß-TCP) grafts have shown to be effective in promoting the clinical signs of periodontal regeneration in intrabony defects. The aim of our study was to clinically and radiographically evaluate the efficacy of HA and ß-TCP composite bone graft material in the treatment of intrabony three-wall defect. MATERIALS AND METHODS: Twenty patients participated in this study. Interproximal bony defects were surgically treated with a combination of HA-ßTCP (biphasic calcium phosphate). Changes in clinical parameters such as gingival status, probing pocket depth, clinical attachment, and radiographic estimation of the amount of bone fill were evaluated after 6 months postoperatively. STATISTICAL ANALYSIS USED: Student's "t" test. RESULTS: This treatment modality resulted in significant pocket depth reduction and clinical attachment gain which were observed to be 2.938 mm (47.04%) and 3.188 mm (29.09%), respectively. The defect fill as seen radiographically was 3.204 mm (63.195%). All the differences were highly significant and in favor of postoperative group. CONCLUSION: The results of this study suggest that HA-ßTCP (biphasic calcium phosphate) provides an added regenerative effect in promoting the clinical resolution of intrabony three-wall defects in patients with periodontitis.

Angiofibroma on cheek mucosa: a rare entity and its management with laser.

A rare presentation of an angiofibroma in the oral cavity is reported, which was treated with a diode laser. The benefits of laser treatment include bloodless procedure with instant precise coagulation of vessels. Although rare and unusual, it is suggested that angiofibroma should be included as one of the differential diagnoses of soft tissue swellings in the oral cavity.
