This study evaluated the impact of soft tissue grafts to reduce marginal peri-implant recession (MPR) after 1 year of follow-up. A total of 24 patients with one single failing maxillary incisor presenting facial bone dehiscence and receiving an immediate implant, bone graft, and provisional were randomly divided into three groups (n = 8 in each group): control (CTL), collagen matrix (CM), and connective tissue graft (CTG). Clinical, photographic, and tomographic analyses were performed to evaluate tissue alterations. The use of a CTG avoided MPR (P < .05) and provided better contour of the alveolar ridge (P < .01) and greater thickness (P < .05) of the soft tissue at the implant facial aspect.
本研究评估了软组织移植对减少种植体周围边缘骨吸收（MPR）的影响，随访1年。共有24例单颗上颌切牙种植失败且存在面部骨缺损的患者，接受了即刻种植、骨移植和临时修复，随机分为三组（每组n = 8）：对照组（CTL）、胶原基质组（CM）和结缔组织移植组（CTG）。进行临床、摄影和断层扫描分析以评估组织变化。使用结缔组织移植可避免种植体周围边缘骨吸收（P < 0.05），并使牙槽嵴轮廓更佳（P < 0.01），种植体面部软组织厚度更大（P < 0.05）。
