摘要： 本文介绍1例上颌窦底自行成骨病例 ,患者拔除左上颌第一前磨牙后拟行种植手术,术前CBCT提示拔牙窝密度较低,与上颌窦底相近,术中见拔牙窝创口愈合不佳,彻底搔刮拔牙窝内肉芽后植入骨填充替代材料和可吸收性胶原膜,牙龈严密缝合。术后6个月重新拍摄CBCT显示,上颌窦底黏膜下方出现新生的骨组织,自行成骨高度约为3.7 mm, 种植区骨量高度由6 mm左右增高至10 mm左右。

Abstract: This article reports a case of spontaneous bone formation on the maxillary sinus floor. This patient was scheduled to undergo dental implant surgery after extraction of maxillary left first premolar. The preoperative CBCT showed that bone density of extraction socket was low and the bottom of extraction socket was close to maxillary sinus floor. After tooth extraction and cleaning of granulation tissue, the socket was filled with bone graft material and covered with resorbable collagen membrane, and gingival flap was tightly sutured. Six months later, CBCT showed that new bone formed under the membrane of maxillary sinus floor. The vertical bone height was increased from approximately 6 mm to 10 mm.
