Oral and maxillofacial surgeryThe effect of drilling speed on early bone healing to oral implants

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
