The aim of this investigation was to evaluate a new resorbable, monolayer, noncross-linked collagen barrier membrane for immobilizing bone augmentation material during horizontal guided bone regeneration (GBR) procedures. GBR was performed on 36 consecutive patients in 49 sites, with 103 implants placed either simultaneously or after a healing period. Healing time, suture retention, postoperative complications, and functional outcome after GBR, implant placement, and prosthesis loading were assessed. A wound dehiscence rate of only 12% and a graft failure rate of 4% occurred. Mean healing time was 5.8 months for simultaneous placement and 7.9 + 4.8 months for two-stage procedures. The implant survival rate was 100% after a mean follow-up of 18.3 months from implantation. These early data demonstrate a low dehiscence rate and excellent potential of this new noncross-linked collagen membrane for use with horizontal ridge augmentation.
本研究的目的是评估一种新型可吸收的单层非交联胶原屏障膜，用于在水平引导骨再生（GBR）手术过程中固定骨增量材料。对49个部位的36例连续患者进行了GBR，同时或在愈合期后植入了103颗种植体。评估了GBR、种植体植入和义齿加载后的愈合时间、缝线保留情况、术后并发症和功能结果。伤口裂开率仅为12%，植骨失败率为4%。同期植入的平均愈合时间为5.8个月，两阶段手术的平均愈合时间为7.9 + 4.8个月。从植入开始平均随访18.3个月后，种植体存活率为100%。这些早期数据表明，这种新型非交联胶原膜的裂开率低，用于水平牙槽嵴增量具有极佳的潜力。
