[The preparation procedure of TiAdapt abutment effect on the implant to abutment joint stability].
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.


CONCLUSIONS
These results indicate that the implant to abutment joint stability has been strengthened by the abutment preparation procedure.
