A cast-free approach is described to fabricate an implant-supported interim restoration by using the postoperative cone beam computed tomography (CBCT) scan to locate the placed implant. A postoperative intraoral scan was aligned to the postoperative CBCT scan through a dental implant planning software program. An attached interim abutment and implant analog complex was then scanned and superimposed on the placed implant in the postoperative CBCT scan. Once the best alignment was achieved, a virtual cast was generated, and an interim restoration with bilateral positioning wings was fabricated on the interim abutment and inserted during the second-stage surgery. This technique offers a cast-free approach to inserting an implant-supported interim restoration immediately after the second-stage surgery to guide the healing of the soft tissue that can minimize chairside time and optimize the clinical workflow.

描述了一种使用术后锥形束计算机断层扫描制作种植体支持的临时修复体的免铸造方法(CBCT) 扫描以定位植入的植入物。通过牙种植体规划软件程序将术后口内扫描与术后 CBCT 扫描对齐。然后在术后 CBCT 扫描中扫描附着的临时基台和种植体模拟复合体并将其叠加到放置的种植体上。一旦达到最佳对齐，就会生成虚拟模型，并在临时基台上制作带有双侧定位翼的临时修复体，并在二期手术中将其插入。该技术提供了一种无需石膏的方法，可在二期手术后立即插入种植体支持的临时修复体，以指导软组织的愈合，从而最大限度地减少椅边时间并优化临床工作流程。
