手術シミュレーションを用いて歯槽骨延長術を行った歯科インプラント治療の一例

Abstract

Alveolar bone loss requires alveolar ridge augmentation for implant treatment. Alveolar distraction osteogenesis has been used for the patients who require major alveolar ridge augmentation as a beneficial surgical procedure, because this procedure has little limitation on the distraction and allows expansion of the soft tissue at one time. However, this procedure has several disadvantages which include difficulty in adjusting the extension direction and a risk of infection due to the exposure of the bone extender. In this study, we report that we decided the treatment strategy using surgical simulation based on an actual model and that we performed implant treatment after alveolar distraction osteogenesis, producing a good outcome. A 59-year-old man had jaw bone atrophy and a mandibular 4-｜-3 defect due to a traffic accident. Since vertical and horizontal bone atrophy was pronounced, we planned alveolar distraction osteogenesis as a surgical procedure for alveolar ridge augmentation. We performed alveolar distraction osteogenesis using surgical simulation. After alveolar distraction osteogenesis, we placed implants and performed occlusal reconstruction, finally producing a good outcome. Alveolar distraction osteogenesis using surgical simulation is an excellent surgical procedure for alveolar ridge augmentation, because it is highly reproducible and expected to produce functionally an cosmetically good outcomes.
