Abstract

This study was performed to determine the failure strength and pattern of implant prosthesis luted with resin cement between gold cylinder and superstructure, and to evaluate the bonding strength of resin cement. To evaluate failure strength and pattern, the groups were divided into 2. Group 1 : Casted gold cylinder Group 2 : Luted with resin cement between gold cylinder ans superstructure. To evaluate effects of the bonding strength of the implant prosthesis luted with resin cement according to storage condition, the groups were divided into 3 : Group A : Stored in waste at $37^{\circ}C$ for 24 hours. Group B : 1000 cycles thermocycled between $5^{\circ}C\;and\;55^{\circ}C$ in water. Group C : Stored in water at $37^{\circ}C$ for 30 days. The results were as follows. 1. Failure was found at gold screw in all specimens of group 1 & 2. 2. The bond strength in group 1 and 2 was 189.86 and 188.14kgf. There was no statistically significant difference between group 1 and 2(P>0.05). 3. The bond strength of group A, B and C was 53.28, 45,86 and 39.29Kgf. There result suggest the advantage of an improved fit of superstructure to the abutment and a simple procedure. But there was a measurable decrease of the bond strength according to storage condition. So, Further research is necessary to evaluate of the implant prosthesis luted with resin cement between gold cylinder and superstructure.
