Key Points

This research evaluates how different materials affect the stability of temporary implant prostheses.
Compared conventional resins with 3D-printed resins
Assessed load bearing capacity and flexibility of each material
Evaluated time efficiency in prosthesis production
High-impact resin exhibited greater flexibility
3D-printed resins demonstrated superior load bearing capacity
Both materials proved effective for temporary implant-supported reconstructive use

Abstract

Material selection critically influences the biomechanical stability of cantilevered provisional implant prostheses. The high-impact resin showed higher degree of flexibility; and the RI group greater load bearing capacity, time efficiency, and predictability, therefore both are suitable alternatives for full-arch temporary implant-supported rehabilitations.
