上颌后牙缺失会严重影响咀嚼功能,不利于患者正常的饮食,还会影响美观。当前,修复缺失牙的有效途径是人工种植牙。然而上颌后牙缺失后,会因上颌窦气化、后牙牙槽嵴萎缩、骨质疏松等因素影响,使得垂直骨量不够,进行牙齿种植时,人工种植牙难以常规植入固定[1]。上颌窦提升术是一种改善上颌窦底垂直骨量的方法,能有效解决人工种植体难植入的问题,临床潜在价值巨大。现就上颌窦提升术在口腔种植修复中的临床应用效果进行观察,现报道如下。
The loss of the maxillary posterior teeth can seriously affect the masticatory function, is not conducive to the normal diet, but also affect the appearance. At present, an effective way to repair missing teeth is artificial implant. However, the loss of maxillary posterior teeth, due to maxillary sinus gasification, atrophy of the alveolar ridge of the posterior teeth, osteoporosis and other factors, making the vertical bone is not enough for dental planting, artificial implants are difficult to conventional implantation and fixation [1]. Maxillary sinus ascending is a method to improve the vertical bone mass at the maxillary sinus floor, which can effectively solve the problem of difficult implantation of artificial implants. The clinical potential value is huge. Now on the maxillary sinus lift in the oral implant repair clinical effect observed, are reported below.
