上颌后牙区解剖结构的特殊性导致了上颌后牙缺失后垂直骨量丧失严重,限制了上颌后牙区口腔种植的适应证,增加了种植手术的风险,成为临床上种植义齿修复的主要障碍.上颌窦提升术可以改善萎缩性上颌骨的牙槽嵴高度,而植骨材料的应用可充分解决上颌后部种植骨量不足的问题.本文介绍了上颌窦提升术中,骨替代材料的研究应用情况.%Ridge resorption is the consequence of tooth loss. When the residual bone volume is too diminished and direct replacement of the missing tooth with a dental implant is unsuitable, it may be necessary to augment the deficient ridge prior to dental implant placement. Various reconstructive materials to augment the alveolar bone ridge for osteointegrated dental implants are widely used. Non-vascularized bone, allogenic bone, and artificial bone substitutes are used in sinus lift to segment the sinus floor. This paper describes the recent advances of bone substitute materials in maxillary sinus lift surgery.
