Design of easy disassembly abutment system based on elastic connection

Abstract

The abutment system is a necessity for oral implant repair, traditional abutment systems are mostly of an integrated structure, after oral implant repair, it is difficult to disassemble whether there is implant failure or infection, or daily cleaning and maintenance. Based on the analysis of the problems in the clinical use of the traditional abutment system, this paper proposes a design method of easy disassembly abutment system based on elastic connection. This method changes the traditional abutment integrated mechanism into a two-part structure, and designs an elastic connection device to fix the two-part structure together, which can facilitate the connection and separation. Through performance test and clinical verification, it is proved that the system can meet the clinical requirements in terms of performance and function, and the effect of patients using the system after implant repair is good. In addition, compared with the traditional abutment system, this system has the advantages of convenient installation and disassembly, small occlusal hole of the dental crown, and more beautiful after repair, so, it has good application value.
