摘要: 目的: 观察种植体倾斜植入在上颌后牙区垂直骨量不足患者中的应用效果。方法: 选取2016年1月—2018年6月上颌后牙区剩余骨高度<6 mm行种植修复的患者。其中,行种植体倾斜植入(倾斜角度为25°~35°)患者28例(共植入种植体40颗),为A组;经牙槽嵴顶上颌窦底提升术患者23例(共植入种植体34颗),为B组。利用Kaplan-Meier生存分析法评估种植修复后种植体存留率;术前、术后拍摄曲面体层片或锥形束CT(CBCT),通过图像分析测量软件测量种植体周边缘骨量。采用SPSS 24.0软件包进行数据分析。术后随访3年,检查并记录种植术后基台松动、修复体松动、崩瓷或缺损、食物嵌塞等并发症。结果: 所有种植体观察最长3年,最短1年,A组累积存留率为100%;B组累积存留率为97.06%(1颗种植体修复前脱落),差异无统计学意义(P>0.05);A、B 2组种植体周边缘骨平均吸收高度无统计学差异(P>0.05);随访期间,A组仅有3例患者出现水平食物嵌塞,1例出现中央螺丝松动,B组未见明显并发症。结论: 对于部分上颌后牙区垂直骨量不足患者,种植体倾斜植入在本研究观察期内获得了良好的临床效果。

Abstract: PURPOSE: To observe the clinical effect of tilted dental implants in patients with insufficient vertical bone mass in maxillary posterior region. METHODS: From January 2016 to June 2018,patients who were implanted and restored with residual bone height <6 mm in the maxillary posterior region were selected. Among them, 28 patients with titled implant (titled angle of 25°-35°) (40 implants) were recruited into group A; while 23 patients with transalveolar crest sinus floor elevation (34 implants) were recruited into group B. Kaplan-Meier survival analysis was used to evaluate the implant survival rate after implant restoration. Panoramic X-ray or cone-beam CT (CBCT) was taken pre- and post-operatively, and the average peripheral marginal bone resorption height of the implant was measured by image analysis and measurement software (Digimizer, Belgium). The data were analyzed with SPSS 24.0 software package. The follow-up period was 3 years after surgery, complications such as loose abutment, loosening of the restoration, collapse of porcelain or defect, food impaction were recorded after implantation. RESULTS: All implants were observed for a maximum of 3 years and a minimum of 1 year. The cumulative survival rate of group A was 100%, the cumulative survival rate of group B was 97.06% (one implant was detached before restoration), and there was no significant difference between group A and group B (P>0.05). There was no significant difference in the average marginal bone resorption height between group A and B (P>0.05). During the follow-up period, only three patients in group A developed horizontal food impaction, one patient had loose central screws, and no significant complications occurred in group B. CONCLUSIONS: For some patients with insufficient bone mass in maxillary posterior region, tilted implant placement has good clinical effect during the observation period of this study.
