The purpose of this study is to compare the flexural strength values of four different methods for chair side direct transfer methods of implant housing.

Materials and Methods: Sixty heat–cured polymethylmethacrylate denture blocks were prepared of size 11 (±0.5) x 8 (±0.5) x 38(±0.5) mm. At the centre a hole of 5mmx8mm dimension was made to secure the implant housing.The Implant Housings were embedded in Acrylic Blocks using the four repair techniques Group A:Autopolymerized acrylic resin(APAR)Group B:Light Polymerized acrylic resin(LPAR) Group C:Autopolymerized acrylic resin with sandblasted and silanated attachment housing (APSAR) Group D:Light Polymerized acrylic resin with sandblasted and silanated attachment housing (LPSAR)

The flexural strength of the repaired denture blocks with the attachment housings was measured with three–point bending test using.Statistically analyzed, mean and standard deviation was calculated using ANOVA and Tuckey’s test.

Results: revealed that self–cured acrylic with silanated attachment housing yielded the highest mean flexural strength values (p<0.0001)

Conclusion: Flexural strength of self–cured acrylic with sandblasted and silanated attachment housing was significantly higher than self–cured, light–cured, and light–cured acrylic with sandblasted and  silanated attachment housing groups.
