This case report features a female patient with the chief complaint of needing to replace an anterior crown. After a comprehensive oral assessment and cone beam computed tomography (CBCT) radiographic examination, it was determined that the crown on Tooth #9 was subgingivally fractured. The procedure involved atraumatic extraction of Tooth #9, followed by immediate implant placement. Xenograft bone graft material was placed to complete the space between the buccal bone and the implant. A connective tissue graft (CTG), 1 mm thick and 5 mm wide, was harvested from the palate and placed. The final implant crown was restored using a prefabricated abutment with a titanium base and zirconia ceramic dental material. A well-planned combined treatment, including atraumatic tooth extractions for immediate implants and ideal contouring of soft tissues, can significantly impact the outcome of aesthetic restorations. A single immediate implant-supported crown in the aesthetic zone was able to fulfill the patient's aesthetic expectations at the 2-year follow-up.
本病例报告的主角是一位女性患者，其主要诉求是需要更换一颗前牙冠。经过全面的口腔检查和锥形束计算机断层扫描（CBCT）影像学检查，确定9号牙的牙冠发生了龈下骨折。该手术包括对9号牙进行无创拔牙，随后立即植入种植体。植入异种骨移植材料以填充颊侧骨与种植体之间的间隙。从腭部获取一块1毫米厚、5毫米宽的结缔组织移植物（CTG）并进行植入。最终的种植体牙冠使用带有钛基的预制基台和氧化锆陶瓷牙科材料进行修复。精心规划的联合治疗，包括用于即刻种植的无创拔牙和软组织的理想塑形，可显著影响美学修复的效果。在美学区域植入单个即刻种植支持的牙冠，在2年的随访中能够满足患者的美学期望。
