发明名称 DENTAL ABUTMENT SCREW EXTRACTOR
摘要 Described herein are systems and methods for extracting a broken fragment of a dental abutment screw from a dental implant. An exemplary system comprises an extractor tool having a tubular outer body and a conductor positioned within the tubular outer body, and an applicator that receives and end of the extractor tool and also includes a heating element that converts electrical energy into heat that is conducted to the extractor tool to melt a thermoplastic adhesive in a cavity at the distal end of the extractor tool, such that the melted thermoplastic adhesive can conform to and engage with a broken fragment of a dental abutment screw within a dental implant when the adhesive cools. The extractor tool can then be rotated to unscrew the broken fragment from the dental implant.
