摘要: 目的 本回顾性研究以钛钉为参考平面,比较钛网联合帐篷螺钉技术与自体骨移植在前牙区牙槽嵴水平向骨增量的效果。方法 研究纳入16例(共23个测量位点)前牙区牙槽嵴水平向骨量严重不足的患者。分别采用钛网联合帐篷螺钉技术与自体骨移植进行牙槽嵴水平向骨增量。收集骨增量后即刻及6个月的CBCT数据,以钛螺钉为参考面分别在牙槽嵴顶(crestal width,CW)、中段(midway width,MW)、基底(basal width,BW)3个平面进行骨宽度的测量,同时对骨增量面积进行重建对比,并对钛网是否暴露进行了评价。结果 钛网联合帐篷螺钉技术与自体骨移植在CW、MW、BW 3个测量平面的骨增量宽度及吸收率基本相同,差别无统计学意义;两组获得的骨增量面积和吸收率基本相同,无统计学差异。然而,钛网暴露组在3个测量平面的宽度吸收均显著高于钛网未暴露组。薄龈生物型是钛网暴露的主要因素,后期钛网暴露经一定的抗感染治疗后也可达到临床可接受的骨增量效果。结论 钛网联合帐篷螺钉技术与自体骨块移植都可获得临床可接受的骨增量效果。不过,如果钛网暴露,其骨吸收将显著增加。

Abstract: Objective The aim of this retrospective study was to evaluate the horizontal bone gain at the different levels of alveolar bone using a titanium screw as a reference plane by titanium mesh with tent screw and autologous bone grafting. Methods Sixteen patients and 23 measured points were enrolled in this study. CBCT data immediately and 6 months after bone grafting were measured at crestal (CW), midway (MW), and basal (BW) levels and reconstructed for area measurement using a titanium screw as the reference plane. The exposure of titanium mesh or not had been evaluated. Results There were no statistical differences between the titanium mesh and onlay grafting, and measured levels at CW, MW, and BW, the exposed titanium mesh and not exposed one. The width absorption ratio of titanium mesh and onlay grafting group or at CW, MW, and BW were almost the same. The area of bone gained and absorption ratio were almost the same without statistical differences. However, the width absorption ratio of the exposed titanium mesh at CW, MW, and BW was significantly higher than the not exposed one. Thin biotype was a main factor in the exposure of titanium mesh. The exposed titanium mesh at the late phase can also achieve clinically accepted bone gain after certain anti-inflammatory treatments. Conclusion Ti-mesh with tenting screw technique and autologous bone graft can achieve clinically acceptable bone augmentation effect. However, the absorption ratio significantly increased if exposed.
