 note = {application/pdf, The purpose of present study was to determine the anchorage potential of mini-titanium implant for orthodontic tooth movement in two Beagle dogs. Extracted upper and lower second premolar to maintain the orthodontic mesial tooth movement of third premolar. Sixteen mini-titanium implants (1.0 x 5.0mm; eight loaded and eight control) were placed bilaterally in healed upper and lower jaw bone. After twelve weeks, orthodontic device was applied to upper and lower canine, third and fourth premolars. Third premolars were retracted mesialy on 200g of continuous force for entire sixteen weeks by Ni-Ti closed coilspring that were placed between mini-titanium implant and third premolar. Fluorochrome bone labels (Tetracycline, Calcein blue, Alizarine red and Xylene orange) were injected during orthodontic force application to determine the remodeling at bone-implant interface and effect of tooth movement. Bone contact, remodeling at surrounding bone-implant interface and environment of non-movement and movement tooth were observed by back scattered electron micro images (BSE), electron prove micro analyzer (EPMA), laser scanning micro images (LSM) and light micro scope images. The result of our study showed upper and lower third premolars were bodily moved mesialy 3.5mm on the average and non-loaded control tooth were remain in the force system without any anchorage. Bone contact at surrounding bone-implant interface maintained rigid osseointegration. Slight active bone remodeling was observed at surrounding bone-implant interface during orthodontic force application than non retracted control implant. We concluded that the mini-titanium implants successfully resisted the orthodontic load and could be maintain the tooth movement or remain in orthodontic force system.},
