摘要

即刻预备的全弓种植体治疗是一种流行的治疗方法。传统上,通常需要对预制假体或基台级印模进行椅侧转换。本病例报告描述了一种利用各种数字技术提取预制全弓假体的新方法。在使用定制的手术指南植入种植体并进行骨复位后,将临时修复放置在可堆叠的指南上,并用光固化材料(“液体针”)内衬。这种材料足够坚固,可以在复衬过程中固定钛基,但在取货后,可以快速完全地从钛基和多单元基台上移除。液体针技术使临时假体保持其结构完整性,消除了术后印模的需要,并允许在分娩前进行最小的调整。与假体的数字预规划一起,该技术简化了立即全弧预备的工作流程。

A Novel Method to Pick-up Prefabricated CAD/CAM-Designed Screw-Retained Provisional Prostheses for Immediate Full-Arch Rehabilitations: Liquid Pin Technique.

Full-arch implant therapy with immediate provisionalization is a popular procedure. Conventionally, chairside conversion of a prefabricated prosthesis or an abutment-level impression is usually required. This case report describes a novel approach to picking up a prefabricated full-arch prosthesis utilizing various digital techniques. After implant placement and bone reduction was performed using a customized surgical guide, a provisional restoration was seated on a stackable guide and relined with a lightcured material (the "liquid pin"). This material is strong enough to hold the titanium bases in place during the relining procedure yet can be quickly and completely removed from the titanium bases and multi-unit abutments following the pick-up. The liquid pin technique enables the provisional prosthesis to maintain its structural integrity, eliminates the need for a postoperative impression, and allows for minimal adjustment before delivery. Together with digital preplanning of the prosthesis, this technique streamlines the workflow for immediate full-arc provisionalization.
