Objective

This study evaluated the effect of drilling speed on early bone healing in dog tibiae.

Study Design

Thirty-six implants (4.0-mm diameter × 10-mm length) were placed in the proximal tibiae of 6 beagles with drilling speeds of 100, 500, and 1000 rpm, and insertion torque was recorded. Bone-to-implant contact (BIC) and bone area fraction occupancy (BAFO) were evaluated.

Results

Significant increase from 1 to 3 weeks was observed for all groups for BIC, whereas no significant differences between 1 and 3 weeks were detected for the 100- and 500-rpm groups for BAFO (P > .34 and P > .46, respectively). A significant difference from 1 to 3 weeks was observed for the 1000-rpm group (P < .03). The 100- and 500-rpm groups presented significantly higher BAFO than the 1000-rpm group at 1 week (P = .002).

Conclusions

Drilling speed is one of the decisive factors for early osseointegration, and overall, drilling at 1000 rpm seemed to yield the strongest biologic responses.

Animals and implants

This study used 36 screw-root-form endosseous titanium implants (Ti-6Al-4V alloy) of 4.0-mm diameter × 10-mm length (DT Ossean; Intra-Lock International, Inc, Boca Raton, FL, USA). Three drilling speeds were used during implant placement: 100 rpm (n = 12), 500 rpm (n = 12), and 1000 rpm (n = 12). All drilling procedures were conducted under abundant irrigation.

Beagle dogs, approximately 1.5 years of age and in good health, were used after the approval of the bioethics committee for animal

Results

During surgery and healing, no complications or other immediate clinical concerns were noted, and all animals and all implants remained in good stability.

Discussion

Primary stability at the time of surgery is one of the fundamental criteria for the achievement of long-term success of dental implants.30 In the present study, measurements of the peak insertion torque and histologic and histomorphometric parameters (BIC and BAFO) were used to assess primary stability and early bone response to the implant placement in a well-established osteoconductive implant surface.31, 32, 33, 34, 35 The peak insertion torque and the histomorphometric parameters at early
