To evaluate horizontal bone gain and implant survival and complication rates in patients treated with titanium meshes placed simultaneously with dental implants and fixed over them. Twenty-five patients treated with 40 implants and simultaneous guided bone regeneration with titanium meshes (i-Gen®, MegaGen, Gyeongbuk, Republic of Korea) were selected for inclusion in the present retrospective multicenter study. Primary outcomes were horizontal bone gain and implant survival; secondary outcomes were biological and prosthetic complications. After the removal of titanium meshes, the CBCT evaluation revealed a mean horizontal bone gain of 3.67 mm (±0.89). The most frequent complications were mild postoperative edema (12/25 patients: 48%) and discomfort after surgery (10/25 patients: 40%); these complications were resolved within one week. Titanium mesh exposure occurred in 6 patients (6/25 : 24%): one of these suffered partial loss of the graft and another experienced complete graft loss and implant failure. An implant survival rate of 97.5% (implant-based) and a peri-implant marginal bone loss of 0.43 mm (±0.15) were recorded after 1 year. . The horizontal ridge reconstruction with titanium meshes placed simultaneously with dental implants achieved predictable satisfactory results. Prospective randomized controlled trials on a larger sample of patients are required to validate these positive outcomes.
评估在与牙种植体同时植入并固定于其上的钛网治疗的患者中水平骨增量、种植体存活率及并发症发生率。本回顾性多中心研究纳入了25例接受40颗种植体治疗并同时使用钛网进行引导骨再生（i-Gen®，韩国庆尚北道密阳市美格真公司）的患者。主要结局为水平骨增量和种植体存活率；次要结局为生物学和修复并发症。去除钛网后，CBCT评估显示平均水平骨增量为3.67毫米（±0.89）。最常见的并发症为术后轻度水肿（12/25例患者：48%）和术后不适（10/25例患者：40%）；这些并发症在一周内得到缓解。6例患者（6/25：24%）出现钛网暴露：其中1例患者移植骨部分丢失，另1例患者移植骨完全丢失且种植体失败。1年后记录的种植体存活率为97.5%（基于种植体），种植体周围边缘骨吸收为0.43毫米（±0.15）。与牙种植体同时植入钛网进行水平牙槽嵴重建取得了可预测的满意结果。需要对更大样本的患者进行前瞻性随机对照试验以验证这些阳性结果。
