Discrepancies in the passive fit of an implant-retained restoration to its supporting abutments are occasionally encountered during the clinical try-in and evaluation appointment. Frequently, the framework must then be sectioned and meticulously soldered to achieve accurate seating of the prosthesis. Furthermore, it may be necessary to remove the restoration's existing esthetic porcelain or resin veneer to improve access for soldering. These traditional corrective procedures are likely to require another patient appointment and significant laboratory time. This article describes the alternative use of electric discharge machining to correct the fit of implant-retained restorations that display incomplete seating during the clinical try-in appointment.
在临床试戴和评估预约期间，偶尔会遇到种植体支持的修复体与其支持基台被动就位的差异。通常，此时必须将支架切割并精心焊接，以实现修复体的精确就位。此外，可能需要去除修复体现有的美学瓷或树脂贴面，以改善焊接操作空间。这些传统的矫正程序可能需要再次预约患者，并耗费大量实验室时间。本文介绍了一种替代方法，即使用电火花加工来矫正种植体支持的修复体在临床试戴预约期间出现的就位不完全问题。
