This study investigated the use of distraction osteogenesis for alveolar ridge augmentation.
Four dogs each had two superior and two inferior implants placed horizontally into an edentulous mandibular quadrant and, after integration, a distraction device was applied. An osteotomy was made to allow the ridge to be distracted vertically. After 10 mm vertical distraction, the device was stabilized.
The vertical augmentation averaged 8.85 +/- 1.05 mm after 10 weeks of healing. Serial sections showed that bone had formed between the distracted segments, creating an augmented ridge.
Distraction osteogenesis has the potential for use in augmentation of the alveolar ridge.
本研究调查了牵张成骨术在牙槽嵴增高术中的应用。
4只犬在下颌无牙象限水平植入2颗上颌种植体和2颗下颌种植体，种植体植入并整合后，应用牵张装置。进行截骨术以使牙槽嵴能够垂直牵张。垂直牵张10毫米后，使装置稳定。
愈合10周后，垂直增高平均为8.85±1.05毫米。连续切片显示，在牵张节段之间形成了骨组织，形成了增高的牙槽嵴。
牵张成骨术有用于牙槽嵴增高的潜力。
