PURPOSE
The purpose of this retrospective study was to evaluate crestal stability of alveolar augmentation using an interpositional bone graft for dental implant restorations.
PATIENTS AND METHODS
Eight patients with 10 graft sites were followed from 1 to 4 years with panographic evaluation to determine if dimension changes of the alveolar graft sites had occurred.
RESULTS
Ten graft sites showed stability and maintenance of alveolar form and osseointegration of restored dental implants. Very little loss of crestal height was observed; 20 of 22 implants placed remained stable at follow-up.
CONCLUSION
The interpositional alveolar bone graft appears to be a viable alternative to block grafting or guided bone regeneration.
目的
本回顾性研究的目的是评估使用植入性骨移植进行牙种植修复时牙槽嵴增高的稳定性。
患者与方法
对8例患者的10个移植部位进行了1至4年的随访，通过全景X线评估来确定牙槽嵴移植部位是否发生尺寸变化。
结果
10个移植部位显示出牙槽嵴形态的稳定性及维持情况，以及修复牙种植体的骨整合。观察到嵴顶高度仅有极小的丢失；22颗植入的种植体中有20颗在随访时保持稳定。
结论
植入性牙槽骨移植似乎是块状骨移植或引导骨再生的一种可行替代方法。
