This study aimed to clinically and radiographically evaluate the results of guided bone regeneration (GBR) using three-dimensional preformed titanium mesh (3-D-PFTM) for non-contained horizontal defects in 100 consecutive cases. This study involved 100 patients (129 implants) with peri-implant non-contained horizontal defects. The patients were divided into three groups: 3-D-PFTM alone (Group 1), 3-D-PFTM plus cross-linked collagen membrane (Group 2), and 3-D-PFTM plus non-cross-linked collagen membrane (Group 3). Each implant was evaluated radiographically using CBCT at baseline and 6 months postoperatively. At the platform level, the mean horizontal hard tissue gain of all the sites was 3.1 ± 1.3 mm at 6 months postoperatively. The mean rate of mesh exposure was 11.8% in Group 1, 4.2% in Group 2, and 5.0% in Group 3. The mean hard tissue gain rate was 71.0 ± 23.0% in group 1, 84.2 ± 21.5% in group 2, and 84.0 ± 22.9% in group 3. Groups 2 and 3 showed significantly higher hard tissue gain rates than group 1. However, there was no significant difference between the rates in groups 2 and 3. Within the limitations of this study, 3-D-PFTM should be considered as a valuable option for GBR for peri-implant non-contained horizontal defects. The use of an additional resorbable collagen membrane provides additional advantages.

三维预成形钛网对100例连续性种植体周围非均质水平缺损影响的回顾性分析

这项研究旨在临床和放射学上评估连续100例使用三维预制钛网(3-D-PFTM)进行的非骨性水平缺损的引导骨再生(GBR)的结果。这项研究涉及100例(129颗种植体)患有种植体周围无水平缺陷的患者。将患者分为三组:单独使用3-D-PFTM(组1),使用3-D-PFTM加交联的胶原膜(组2)和使用3-D-PFTM加非交联的胶原膜(组2)。第3组)。在基线和术后6个月使用CBCT对每个植入物进行X线摄影评估。在平台水平,术后6个月所有部位的平均水平硬组织增厚为3.1±1.3 mm。组1的平均网孔暴露率为11.8%,组2为4.2%,组3为5.0%。第1组的硬组织平均增加率为71.0±23.0%,第2组为84.2±21.5%,第3组为84.0±22.9%。第2和第3组的硬组织获得率明显高于第1组。在第2组和第3组之间的比率没有显着差异。在本研究的局限范围内,应将3-D-PFTM作为GBR的有价值的选择,以用于种植体周围非封闭性水平缺损。使用附加的可吸收胶原膜提供了附加的优点。3-D-PFTM应该被认为是GBR的宝贵选择,可用于种植体周围未包含的水平缺损。使用附加的可吸收胶原膜提供了附加的优点。3-D-PFTM应该被认为是GBR对于种植体周围非封闭性水平缺损的宝贵选择。使用附加的可吸收胶原膜具有其他优点。
