Objective:
This study was designed to determine the difference in the implant to abutment joint stability resulting from the preparation procedure in adjusting the TiAdapt abutment.
Methods:
Thirty Branemark implants (10RP, 10NP, 10WP) and 10 TiAdapt RP, TiAdapt NP and TiAdapt WP abutments formed the experimental populations of 3 groups. Samples in each groups were further divided into subgroups A and B. Subgroup A was operated with preparation procedure whereas the other served as control. The torque required and the gap between abutment and implant before and after preparation were measured.
Results:
There were no significant differences in group RP and group WP; there were significant differences in group NP at the significance level of 0.05.
Conclusion:
These results indicate that the implant to abutment joint stability has been strengthened by the abutment preparation procedure.
