A modified implant abutment holder fabricated with fused deposition modeling to improve the transfer process for implant-supported restorations

Ingestion or aspiration of an implant abutment can occur in patients during the process of abutment transfer for implant-supported restorations, especially in the posterior region. A technique of fabricating an abutment holder is described to prevent ingestion or aspiration by computer-aided design (CAD) and fused deposition modeling (FDM). The modified abutment holder has a serrated handle for a firm grip and a barrel-shaped fixed portion that firmly secures the abutment. The modified holder is more secure than the conventional hexagon screwdriver. Furthermore, abutment holders can be easily manufactured by using 3D printers and repeatedly used for multiple implants restoration without substitution.
