Purpose:
Recently, fiber-reinforced composite resin (FRC) has been introduced as a framework material for maxillofacial silicone prostheses. The purpose of this research was to study the tensile bond strength between a room temperature-polymerized maxillofacial silicone elastomer and a unidirectional FRC.
Materials And Methods:
Three different bonding agents were compared. Specimens were loaded in tension mode according to ISO 22401 in a universal testing device with a crosshead speed of 10 mm/min until bonding failure occurred. The influence of the surface characteristics (ground vs intact) was also studied.
Results:
The highest tensile bond strength was seen with Gold Platinum Primer A-330-G, followed by Sofreliner primer. One-way analysis of variance revealed that the surface treatment of the FRC and the adhesive used had a significant effect on tensile bond strength between silicone and FRC (P < .05). Grinding enhanced adhesion, especially with Gold Platinum Primer A-330-G and Sofreliner primer. The fracture type also changed to more cohesive in nature.
Conclusion:
The FRC substructure can successfully be bonded to maxillofacial silicone elastomer by using primer containing methyl ethyl ketone and dichloromethane solvent. Bonding can be improved by roughening the FRC substrate via grinding.
