ABSTRACT
INTRODUCTION:
Bone response to orthodontic loading was compared around 2 different types of osseointegrated implants (porous surfaced and machined threaded) to determine the effect of implant surface geometry on regional bone remodeling.METHODS:
Five beagles each received 3 implants of each design in contralateral mandibular extraction sites. After a 6-week initial healing period, abutments were placed, and, 1 week later, the 2 mesial implants on each side were orthodontically loaded for 22 weeks. All implants remained osseointegrated throughout orthodontic loading except for 1 threaded implant that loosened. Back-scattered scanning electron microscopy and fluorochrome bone labeling techniques were used to compare responses around the 2 types of implants.RESULTS:
The loaded, porous-surfaced implants had significantly higher marginal bone levels and greater bone-to-implant contact than did the machined-threaded implants.CONCLUSIONS:
Significant differences in peri-implant bone remodeling and bone formation in response to controlled orthodontic loading were observed for the 2 implant designs. Short, porous-surfaced implants might be more effective for orthodontic applications than machine-threaded implants.
