The effect of length parameter on the repair strength of acrylic resin using fibers or metal wires.

Fractures of acrylic resin dentures occur quite often in prosthodontic practice. Autopolymerized acrylic resin is the most popular material for denture repair; however, it is significantly weaker than the intact heat-polymerized resin. Metal strengtheners or fibers have been used to reinforce the resin.

Fracture force, deflection, and toughness of acrylic denture repairs involving glass fiber reinforcement.

Purpose: Fractures in acrylic resin dentures occur quite often in the practice of prosthodontics. A durable repairing system for denture base fracture is desired to avoid recurrent fracture. The purpose of this study was to evaluate the fracture force, deflection, and toughness of a heat-polymerized denture base resin repaired with autopolymerized resin alone (C), visible light-polymerizing resin (VLC), or autopolymerizing resin reinforced with unidirectional (Stick) (MA-FS) and woven glass fibers (StickNet) (MA-SN).
