应用三维预成型钛网在上颌前牙区骨增量疗效的临床研究

目的:分析三维预成型钛网在上颌前牙区水平骨增量并同期种植手术的临床疗效。方法:筛选2016~2018年行上颌前牙延期种植的35名患者,根据植骨方式的不同分为2组:三维预成型钛网组和传统引导骨再生(GBR)组,共植入45枚种植体。在不同阶段利用锥形束CT(CBCT)对植骨术区牙槽骨量进行测量,同时评估牙龈组织美学和种植体周健康指数等。结果:比较2组间植骨术后(T1)至种植修复完成半年(T3)的牙槽骨吸收量(L3),三维预成型钛网组的L3(0.98±0.08)mm少于传统GBR组(1.51±0.14)mm。同时,三维预成型钛网组的红色美学评分为(10.50±0.27),高于传统GBR组得分(9.45±0.19)。两组种植体T3期的探诊深度、牙龈指数、菌斑指数均无统计学差异。结论:采用三维预成型钛网辅助上颌前牙骨量不足的种植修复中,可获得稳定的水平骨增量和更好的红色美学效果。

Effect of Three-dimensional Pre-formed Titanium Mesh in Maxillary Anterior Region

Objective:To analyze the clinical effects of simultaneous implantation with three-dimensional pre-formed titanium mesh in the maxillary anterior region.Methods:Thirty-five patients who received delayed maxillary anterior teeth implantation from 2016 to 2018 were divided into two groups according to the types of bone grafting:three-dimensional pre-formed titanium mesh group and traditional GBR group,with a total of 45 implants.CBCT was used to measure the changes of alveolar bone volume in the bone grafting area at different stages.The gingival tissue esthetics and implant health index were also evaluated and analyzed.Results:Comparing the difference of alveolar bone absorption(L)of two groups between bone grafting procedure(T)and definitive restoration(T),the three-dimensional titanium mesh group was less than(0.98±0.08 mm)L in the traditional GBR group(1.51±0.14 mm).The pink esthetic score(PES)of three-dimensional titanium mesh group(10.50±0.27)was higher than that of the traditional GBR group(9.45±0.19).The probing depth(PD),the gingival index(GI),and the plaque index(PLI)of the two groups in T showed no statistical difference.Conclusion:Three-dimensional pre-formed titanium mesh can provide more stable horizontal bone augmentation and better aesthetic effect for implant restoration in anterior maxilla.
