Evaluation of augmented alveolar bone with vertical alveolar distraction osteogenesis and implant installation

Abstract

Introduction:The purpose of this study was to evaluate the clinical result of vertical alveolar distraction, especially the distracted alveolar bone and installed implants. Materials and Methods: Twenty-one patients who have been received the vertical alveolar distraction and implant installation on 22 areas (3 maxilla and 19 mandible) using intraoral alveolar distraction device were examined. After consolidation period of 3-4 months, distraction devices were removed and 91 implants were installed in the distracted alveolar bone. The distracted bone and implants were evaluated clinically and radiographically. Results: Mean height of distracted alveolar bone was 7.5±3.2 mm (range: 2.5-15.0 mm). Mean follow-up period after completion of the distraction was 3.1 years (range: 1.4-11.5 years). Mean resorption of distracted alveolar bone was 1.6±1.8 mm. The success and survival rates of implants was 95.3% and 100%, respectively.. Conclusion:Results of this study indicate that vertical alveolar distraction procedure is a useful and stable method for alveolar ridge augmentation and implantation.

Vertical Ridge Gain with Various Bone Augmentation Techniques: A Systematic Review and Meta‐Analysis

“…In DO, both hard and soft tissues are augmented, and a transport segment is mobilized in a similar manner as for interpositional bone grafting, simultaneously preserving attachment to the crestal and lingual tissues . The distractor is fixed to the transported and basal bone segments with an approximately 1 to 2 mm gap between the 2 segments.…”

Efficacy of Alveolar Vertical Distraction Osteogenesis and Autogenous Bone Grafting for Dental Implants: Systematic Review and Meta-Analysis

“…Alveolar distraction osteogenesis has been used to correct vertical deficits of alveolar ridges before implant placement since the 1990s. [12][13][14] The most favorable advantages of alveolar distraction osteogenesis are the simultaneous increase of soft tissue and, as a result, greater amounts of vertical augmentation than bone grafting. 15,16 However, many complications have been reported, although distractor devices and techniques have been developed continuously.…”
