目的评价简化上颌窦内提升牙种植术的临床效果。方法因上颌磨牙缺失行种植修复的患者60例,根据上颌窦底距牙槽嵴顶之间的垂直距离分为两组:实验组(A组)31例,上颌窦底到牙槽嵴顶的垂直距离3.8-7.8mm,应用简化内提升的手术方法共计植入38枚长度为8mm的较短种植体,均未使用上颌窦冲顶器及骨粉;对照组(B组)29例,上颌窦底到牙槽嵴顶的垂直距离12.8-14.0mm,常规方法植入35枚长度均为10mm的种植体。随访9-24个月,比较两组种植牙成功率。结果 A组和B组种植牙成功率相仿(97.37%vs.97.14%)(P>0.05)。结论严格掌握适应证,上颌后牙区牙缺失采用简化内提升牙种植术临床效果可靠。
Objective To evaluate the clinical effect of simplified maxillary sinus ascending dental implants. Methods Sixty patients undergoing maxillary molar restoration were divided into two groups according to the vertical distance between maxillary sinus and alveolar crest: 31 cases in experimental group (group A), the maxillary sinus to alveolar crest Vertical distance of 3.8-7.8mm, the use of simplified surgical methods to enhance the total implantation of 38 shorter implant length of 8mm, were not used maxillary sinus top and bone meal; control group (B group) 29 cases of maxillary sinus floor The vertical distance to the crest of the alveolar ridge was 12.8-14.0 mm. 35 implants of 10 mm in length were implanted routinely. The patients were followed up for 9-24 months. The success rate of dental implants in both groups was compared. Results The success rates of implanting teeth in group A and group B were similar (97.37% vs.97.14%) (P> 0.05). Conclusion Strict indications, the maxillary posterior teeth of the missing teeth using simple and effective dental implant surgery to improve the clinical effect.
