ABSTRACT
Objective:
To study the effects of fluor-hydroxyapatite (FHA) coating titanium alloy on the osseointegration and peri-implantitis of orthodontic micro-implant.Methods:
Titanium of FHA alloy (FHA group) and titanium alloy(control group) orthodontic micro-implants were respectively planted into buccal alveolar bone in mandibular premolar area of rabbits.Scanning electron microscope was used to observe the osseointegration around the micro-implants.ELISA was employed to detect TNF-α in the gingival crevicular fluid around the implants.Results:
The FHA-coating titanium alloy orthodontic micro-implants led to higher bone density,smaller marrow cavity,and lower TNF-α level and shorter lasting period of TNF-α over-expression than the controls (P < 0.05).Conclusion:
The FHA-coating titanium alloy orthodontic micro-implant has better histocompatibility and may inhibit peri-implantitis.
