Low-intensity pulsed ultrasound stimulation significantly enhances the promotion of bone formation around dental implants

Abstract

The effect of low-intensity pulsed ultrasound stimulation (LIPUS) on bone formation around dental implants was studied histologically and mechanically after a dental implant was inserted into the femur of male Japanese white rabbits. LIPUS daily treatment started on the day after implant placement for 14 days. Histologically, new bone formation was observed around the implant. Implant removal torque values were significantly higher in LIPUS-treated group (44.0 - 58.8 N cm) than the control group (32.0N cm). Moreover, bone contact ratio was significantly higher in LIPUS-treated group than the control group. The results suggest that clinical application of LIPUS for dental implants may promote osseointegration. © 2011 The Hard Tissue Biology Network Association.
