Abstract

Purpose: To examine the influence of time of low-magnitude, high-frequency (LMHF) loading, whole-body vibration (WBV) on peri-implant bone healing. Materials and Methods: A custom-made Ti implant was inserted into the medio-proximal site of one tibia of 95 rats and was left to heal for 1 or 4 weeks. The daily WBV consisted of 15 consecutive frequency steps (12, 20, 30, ⋯, 150 Hz) at an acceleration of 0.3 g. The rats were divided into five groups with different loading times: 0 (control/non-loading), 1.25, 2.5, 5 and twice 1.25 min. (with an interim recovery period) of loading. Bone-to-implant contact (BIC) and peri-implant bone fraction were measured. Results: BIC of every test group was significantly higher than that of the control group for both healing periods. In the 4-week healing group, BIC and BFs (in all region of interests) were significantly higher in the case of twice 1.25 min. of loading compared with 1.25 min. of loading. Conclusion: Time of loading significantly influenced the effect of the WBV on peri-implant bone healing. Twice 1.25 min. of loading appears to have the most favourable effect. LMHF loading with a particular time sequence can stimulate peri-implant bone healing and formation.
