萎缩的牙槽嵴对于种植牙而言是一个不利的因素,在植入种植体之前牙槽骨嵴增量手术能够使骨的体积增加。在上颌前牙区,牙槽嵴增量不仅有利于后期种植体的植入而且可以获得更好美学效果。本文详述用钛网结合异体骨移植和人骨形成蛋白治疗上前牙区部分牙缺失部位的颊舌向骨缺损。通过这种方法可获得一定的骨增量,8个月后植入种植体,在植入种植体后4个月行二期手术和临时修复,4个月后进行永久修复,追踪时间为2年。
Atrophic alveolar ridge is an unfavorable factor for dental implants, and alveolar ridge crest surgery can increase the volume of the bone before implants. In the maxillary anterior region, alveolar crest augmentation is not only conducive to the implantation of late implants but also can get better aesthetics. This article details the use of titanium mesh combined with allogeneic bone graft and human bone morphogenetic protein in the treatment of anterior teeth area missing parts of the bucco-buccal and lingual bone defects. A certain amount of bone augmentation was obtained in this way. Implants were implanted after 8 months. Secondary surgery and temporary repairs were performed 4 months after implants. Permanent repairs were performed 4 months later. The follow-up time was 2 year.
