Many factors influence osseointegration, such as bone type and quality of bone-to-implant contact. However, the concept of “ideal” site preparation is poorly defined.

Wang and coworkers1 used a mouse model to investigate the effects of heat generation during osteotomy on bone remodeling around implants. They used drill diameters and radial velocities that were designed to be representative of site preparation in the clinic.

During osteotomy, faster drill speeds led to increased heat generation versus slower speeds. Consequently, osteocyte death in the surrounding bone was more prevalent after faster versus slower drilling. Also, after three days, less new bone formed in sites where faster versus slower drill speeds had been used. These results help to better define the cellular repercussions of drilling, and show how carefully designed, clinically representative animal models may be useful to inform future practice.
