Aim:To compare and evaluate the treatment outcome and postoperative complications in mandibular fractures using 2- and 3-dimensional miniplates.Materials and Methods:This study consisted of a sample of 28 patients (40 fracture sites) divided randomly but equally (single-blind control trial study) into two groups. Each group contains 14 patients (20 similar fracture sites in each group). Group 1 was treated with open reduction and internal fixation using 3-dimensional (3-D) miniplates. Group II was treated using 2-dimensional (2-D) 2-mm miniplates.Results:Out of 14 patients treated by conventional 2-mm miniplates, 2 patients developed occlusal discrepancy, another 2 had postoperative mobility at fracture site, and 1 developed plate failure and subsequent infection, which was treated by removal of the plate under antibiotic coverage. One patient treated by 3-dimensional plates had tooth damage.Statistical Analysis:Chi-square test.Conclusion:The results of this study suggested that the treatment of mandibular fractures (symphysis, parasymphysis, and angle) with 3-dimensional plates provided 3-dimensional stability and carried low morbidity and infection rates. The only probable limitations of 3-dimensional plates were excessive implant material due to the extra vertical bars incorporated for countering the torque forces.

One stage lateral sinus lift procedure with alloplastic bone graft material in combination with 2 stage implant placement has a predictable outcome in patients with severe resorption of posterior maxilla.

Aims and objectives:To reduce the prolonged waiting period post tooth extraction for rehabilitation with implants. This study was carried out to determine the outcome of implants placed into fresh extraction sockets with the simultaneous use of particulate bone graft. Patient response to rehabilitation with immediate placement single tooth implants was monitored clinically and radiographically. Materials and methods:Among seven patients, with the average age of 28 years were treated for single tooth replacement in fresh extraction sockets in the esthetic zone by means of 2 stage immediate placement of implant. Bioactive glass particulate bone graft was used as bone graft material. Reason for teeth loss was caries, trauma and internal resorption. All patients were followed clinically and radiographically for 1 year after loading of implant.Results: Follow-up was done after stage I surgery (placement of implant) for pain, soft tissue dehiscence, inflammation, altered sensation at site of implant placement monthly for 4 to 6 months. After giving final prosthesis, patients were evaluated for bleeding index (Muhlemann and Son), plaque index (Turesky-GilmoreGlickman) gingival index (Loe and Silness), marginal bone loss (parallel cone technique using IOPA) with follow-up at 6th and 12th months. All the implants were osseointegrated at the time of abutment placement. Radiographic examination showed only slight marginal bone around the implants. Conclusion:Hence, implants can be placed successfully in fresh extraction socket using bioactive glass (perioglass) particulate bone graft material to fill gap between implant and bone through a submerged (2 stage) surgical technique.

Aims and Objectives: To evaluate the efficacy, clinical acceptability, and patient response to rehabilitation of single edentulous spaces with restorations over screw retained mini dental implants. Materials and Methods: This study consisted of seven patients (four female and three male). Single-stage, 2.4 mm diameter and 10 and 13 mm long, screw form with integrated abutment, self-tapping, threaded, acid-etched and sandblasted, pure titanium mini dental implants were placed in 10 single, narrow, edentulous spaces (<6 mm bucco-lingually) in the anterior region of the jaw (four in the maxilla and three in the mandible). Results: Post-operative evaluation of mini dental implant was done 12 months of implant loading. Following clinical and radiographic parameters were evaluated: Gingival status (Gingival index), probing depth (By William's periodontal probe), stability (periotest), patient compliance, prosthesis loosening and fracture, and marginal bone loss (using Intra-oral periapical radiograph, orthopantomograph) Conclusion: Single-tooth mini-implant restorations demonstrated a rate of success similar to those reported by previous studies for standard single-tooth implant restoration. Therefore, a mini-implant may represent a valid treatment alternative when space problems do not permit the use of standard wide-diameter implants. However, more long-term studies are needed to determine the long term success rate of this self-tapping mini implant design.
