目前,口腔种植修复技术日益成熟,成功率可达95%以上,已成为牙缺失的主要修复方式~([1])。对于上颌第二磨牙游离缺失、伴或不伴上颌第一磨牙缺失的患者,上颌后牙区窦嵴距不足是影响该区种植修复效果的主要因素。临床常采用上颌窦提升术来解决窦嵴距高度不足的难题。但部分患者上颌窦区存在病变或结构异常,无法进行上颌窦提升术,另外一些患者则过度在意上颌窦提升术所造成的创伤,而拒绝行种植修
At present, oral implant repair technology is increasingly mature, the success rate of up to 95%, has become the main repair of dental loss ~ ([1]). For patients with maxillary second molars free missing, with or without maxillary first molar missing, the maxillary posterior dentate sinus gap is the main factor affecting the effect of implant rehabilitation. Clinical often use maxillary sinus lift to solve the problem of sinus ridge height. However, some patients with pathological or structural abnormalities in the maxillary sinus area, can not be maxillary sinus lift, while others are overly concerned with maxillary sinus surgery caused by trauma, and refused to plant prosthesis
