ABSTRACT
Aim:
This study evaluated the influence of surgical undersized drilling on insertion torque of an implant system at low bone density.Methods:
Implant site preparations were made in two polyurethane foam blocks with different densities, where two preparation techniques were considered Control group (C) conventional drilling, following the manufacturer's instructions; and Group (E) undersized drilling, experimental technique using a final surgical drill with reduced diameter. The artificial bone blocks were selected based on density D1 (0.64 g/cm3) and D2 (0.32 g/cm3). Three groups were considered according to the preparation technique and bone density used (n=10) CD1 conventional drilling technique in artificial bone with higher density; CD2 conventional drilling technique in artificial bone with lower density; and ED2 undersized drilling in artificial bone with lower density. Externalhexagon implants (11 × 4 mm) were inserted and the insertion torque values were measured using a digital torque-meter. Data were submitted to one-way ANOVA followed by Tukey's test (α=0.05).Results:
The results showed significant statistical differences between groups (p<0.001), where the highest insertion torque was found for the Group CD1 (48.9 Ncm) followed by Group ED2 (22.6 Ncm) and Group CD2 (11.7 Ncm).Conclusions:
The undersized drilling technique for implant site preparation leads to increased insertion torque on low bone density. (AU)Key words
