The success of oral rehabilitation of implants depends on the osseointegration of implant fixtures and maintaining the integrity of the connection of prosthetic superstructures to these fixtures. The purpose of this study is to compare the cement bond strength of Temp-Bond among nine pretreated surfaces of commercially pure titanium. One hundred and twenty six plates of commercially pure titanium (ASTM Grade 2) with 15 mm x 5 mm x 1mm were divided equally into nine pretreated surface categories: Paper polishing (grit #800): POL, Alumina blasting: ASB, Alumina buff polishing: ABP, H2O2 immersion for 3 hours: HOI, H2O2 Halogen for 3 minutes: HOH, 60°C for 3 years: LOX, 300°C for 30 minutes: MOX, 600°C for 10 min: HOX, Alumina blasting followed by H2O2 Halogen for 3 minutes: SHH. Seven cemented pairs were overlapped cemented per group with 5 mm-overlapping. Cementation was done by applying a dead-weight of 650 gm for ten minutes inside the incubator at 100%RH. The cemented plates were stored in 37oC distilled water for 24 hours prior to debonding tests at a crosshead speed of 1mm/min. It was found that SHH showed the highest bond strength (5.19 MPa), HOX (3.79 MPa) was the next and these were significantly different form other six groups (including control POL group) with bond strengths ranging from 1.94 to2.86 MPa. Statistically LOX was the weakest group (1.86 MPa). The Fenton reaction using the halogen light source appears to be very effective surface treatment to enhance the cement bond strength.
