Abstract

This clinical report describes the immediate implant placement and restoration for a 47-yearold woman with a protruded and loose maxillary right central incisor. The treatment included minimally invasive extraction, flapless immediate implant placement using a fully guided surgical template, and immediate implant-supported provisionalisation. The interim anatomical prosthesis was fabricated in advance based on preoperative CBCT scans, and the digital technique made it possible to integrate data precisely from different sources. After 6 months of provisionalisation, satisfactory gingival aesthetic and functional improvements were achieved, followed by a definitive screw-retained zirconia restoration. Thus, application of a complete digital workflow could reduce chairside time and create an optimal emergence profile that matches the residual bone architecture of the extraction sites with minimal interference.

基于CBCT扫描的预制种植体支撑临时假体:数字即刻种植体修复一例报告。

本临床报告描述了一名47岁女性上颌右中切牙突出和松动的立即种植体放置和修复。治疗包括微创拔牙，使用完全引导的手术模板进行无瓣即刻种植体放置，以及即刻种植体支持的预备。根据术前CBCT扫描提前制作临时解剖假体，数字技术使不同来源的数据精确整合成为可能。6个月后，牙龈美观和功能得到了满意的改善，随后进行了明确的螺钉保留氧化锆修复。因此，应用完整的数字工作流程可以减少椅边时间，并创建一个最佳的出现轮廓，该轮廓与拔牙部位的残余骨骼结构相匹配，干扰最小。
