This article presents a case report of implant site development in a healthy, nonsmoking 62-year-old man using titanium mesh (Ti-mesh) in conjunction with human cellular allograft for ridge augmentation of a type 4 alveolar ridge defect. The patient presented initially with a severely periodontally abscessed maxillary right central incisor probing to the apex. The tooth was extracted, and after 8 weeks a bone reconstructive procedure was completed using a well-stabilized Ti-mesh and cellular allograft that was covered with a quickly resorbing collagen matrix. After 7 months of undisturbed healing, cone beam computed tomographic evaluation demonstrated a horizontal bone increase of 7 mm and a vertical bone increase of 2.3 mm. This case report demonstrates the benefits of predictable regenerative space maintenance using Ti-mesh in conjunction with a cellular allograft to allow for prosthetically driven implant placement in the esthetic zone.
本文介绍了一例在一名62岁健康、不吸烟男性患者中使用钛网（Ti网）结合人细胞同种异体移植物进行4型牙槽嵴缺损牙槽嵴增高的种植位点开发病例报告。患者最初表现为上颌右中切牙严重牙周脓肿，探诊至根尖。该牙被拔除，8周后使用稳定良好的Ti网和细胞同种异体移植物完成骨重建手术，移植物上覆盖有快速吸收的胶原基质。经过7个月的无干扰愈合，锥形束计算机断层扫描评估显示水平骨增量7mm，垂直骨增量2.3mm。本病例报告证明了使用Ti网结合细胞同种异体移植物可预测性地维持再生空间，以便在美学区域进行由修复驱动的种植体植入的益处。
