영문 초록

The aim of this study was to show the feasibility and potential advantages of using the new intraoral distraction device for alveolar ridge augmentation. Four adult mongrel dogs were used. We designed intraoral distraction device for augmentation of vertical height of the edentulous ridge. The left upper and lower premolars and first molars were extracted and an alveoloplasty was performed to simulate an atrophic ridge. After 12 weeks of healing, an osteotomy was made and the intraoral distraction device was applied in order to distract alveolar segment upward. A permucosal pin was exposed intraorally. Latency period was allowed for 7 days before distraction began. The distraction device was activated with a rate of 1.0 ㎜/day for 9 days. At 2 weeks after completion of the distraction, the device was removed. At 8 weeks after distraction, the animals were sacrificed. Clinical, radiographic, and histologic examinations were performed. Macroscopically, no significant abnormalities such as infection were occurred in the distracted area. The average distracted distance was 7.6±1.4 ㎜ and new bone was formed in the distracted gap in all animals. Bone remodeling without crestal bone resorption was observed in the distracted area. In several animals, fibrous tissue was present in the buccal cortical bone area. These results suggest that the intraoral distraction device may have the potential for use in augmentation of the atrophic edentulous ridge.
