The aim of this study is to evaluate the efficacy of the application of allogenous bone at the maxillomandibular reconstructions for future rehabilitation with dental implants. The patients were submitted to reconstruction of maxilla, using allogeneic bone grafts, in 3 different techniques: onlay grafts for lateral ridge augmentation, onlay and particulate bone for sinus lift grafting, and particulate alone for sinus lift grafts. Clinical and radiographic control was done at the postoperative phase for at least 8 months, until the patient could be submitted to the installation of dental implants. The results showed success in the majority of the cases, and dental implants could be installed. This can be considered an excellent alternative when compared with the use of autogenous grafts; because handling is easier, there is a great amount of material available and a possibility of using local anesthesia, and consequently there is a reduction of patient morbidity.
本研究的目的是评估在颌骨重建中应用异体骨以利于未来进行牙种植修复的疗效。患者接受上颌骨重建,采用同种异体骨移植,有3种不同技术:用于侧方牙槽嵴增高的贴附式移植、用于上颌窦提升移植的贴附式和颗粒状骨移植、以及仅用于上颌窦提升移植的颗粒状骨移植。术后阶段进行临床和影像学检查,至少持续8个月,直至患者能够接受牙种植体植入。结果显示大多数病例取得成功,且能够植入牙种植体。与使用自体移植骨相比,这可被视为一种极佳的替代方法;因为操作更简便,有大量可用材料,并且有可能使用局部麻醉,从而降低了患者的发病率。
