目的
这项研究评估了狗狭窄牙槽骨脊的水平牵张，以及在巩固期间植入到牵张部位的种植体实现骨整合的可能性。
材料和方法
实验中使用了6只体重约9至10公斤的比格犬。拔除下颌前磨牙12周后，使用最初设计的延长器进行水平牙槽骨牵张。牵张完成12天后，在牵张部位植入螺纹型种植体。
结果
种植体植入12周后，薄板层骨从运输段水平上升至种植体表面。植入24周后，种植体完全植入成熟的板层骨中，可见与种植体表面的直接骨接触。
讨论
在狭窄的牙槽骨模型上，使用延长器成功地完成了水平牙槽骨牵张。即使在固定期间种植体被放置在分散的部位，骨整合也是成功的。
结论
在犬类中，水平牙槽骨牵张在狭窄的牙槽骨中植入种植体是一种有益的技术。
PURPOSE
This study evaluated horizontal distraction of the narrow alveolar ridge in dogs and the possibility of achieving osseointegration of implants placed into the distracted site during a consolidation period.
MATERIALS AND METHODS
Six beagle dogs weighing approximately 9 to 10 kg were used in this experiment. Twelve weeks after extraction of the mandibular premolars, horizontal alveolar ridge distraction was performed using an originally designed lengthening apparatus. Twelve days after the completion of distraction, screw-type implants were placed into the distracted site.
RESULTS
Twelve weeks after the placement of implants, thin lamellar bone rose horizontally from the transport segment toward the surface of the implant. Twenty-four weeks after their placement, the implants were fully embedded in mature lamellar bone, and direct bone contact with the implant surface could be seen.
DISCUSSION
Horizontal alveolar ridge distraction was performed successfully by using a lengthening apparatus in the narrow alveolar models. Osseointegration was achieved even though the implants were placed into the distracted site during the consolidation period.
CONCLUSION
Horizontal alveolar ridge distraction can be a beneficial technique in the placement of implants In the narrow alveolar ridge in the dog population.
