目的探讨上颌窦牙体种植的临床效果。方法 2010年3月至2013年4月于许昌市京州口腔行上颌窦牙体种植的患者180例为研究对象,植入种植体197枚。按照上颌窦底与牙槽嵴顶的距离分为观察组和对照组,观察两组患者上颌窦提升情况。结果观察组101例行闭合式上颌窦提升术,成功植入种植钉113枚,上颌窦底高度平均提升(3.71±0.46)mm;对照组79例行开放式上颌窦提升术,成功植入种植钉84枚,上颌窦底高度提升(4.89±0.15)mm。全部种植体周围未见阴影,骨结合良好,无明显骨吸收。结论上颌窦内种植修复需要严格掌握上颌窦提升术的适应证,根据术前测量结果选择合适的术式,术中操作仔细轻柔,提高种植的成功率。
Objective To investigate the clinical effect of maxillary sinus implant. Methods From March 2010 to April 2013, 180 patients with oral maxillary sinus implant in Jingzhou, Xuchang were enrolled and 197 implants were implanted. The maxillary sinus and alveolar ridge were divided into observation group and control group according to the distance between maxillary sinus and maxillary sinus. Results In the observation group, 101 cases underwent closed maxillary sinus lift, 113 implanted implants were successfully implanted, and the height of the maxillary sinus was elevated by (3.71 ± 0.46) mm on average. In the control group, 79 patients underwent open maxillary sinus augmentation and successful implants There were 84 nails and the height of the maxillary sinus increased (4.89 ± 0.15) mm. All implants around the shadow, good bone union, no significant bone resorption. Conclusion The implant in maxillary sinus need strict indications of maxillary sinus lift. According to the results of preoperative measurement, the appropriate surgical procedure is selected. The operation is gentle and gentle, and the success rate of implantation is improved.
