Interventions to augment the mucosal thickness around dental implants are indicated to optimize esthetics and maintain peri-implant health. However, there is a lack of clinical data on the long-term performance of soft tissue substitutes, such as volume-stable collagen matrix (VCMX), compared to autogenous grafts, such as subepithelial connective tissue grafts (SCTGs). This randomized controlled trial aimed to assess 5-year data on clinical and radiographic outcomes at implant sites previously augmented with VCMX or SCTG.

在种植体部位使用体积稳定的胶原基质或自体结缔组织移植物增强软组织：植入物加载后随机对照试验的五年结果

增加牙种植体周围粘膜厚度的干预措施可优化美学效果并保持种植体周围的健康。然而，与上皮下结缔组织移植物 (SCTG) 等自体移植物相比，体积稳定的胶原基质 (VCMX) 等软组织替代物的长期性能缺乏临床数据。这项随机对照试验旨在评估 5 年的临床和影像学结果数据，这些数据涉及先前使用 VCMX 或 SCTG 增强的种植体部位的临床和影像学结果。
