Aim: To compare, through cone-beam computed tomography (CBCT), the root
resorption of two different mini-implant-assisted modalities in intruding the maxillary
incisors. Subjects and Methods: The present study composed of 26 patients (males,
females) aged between 12-18 years who had deep bite and need maxillary incisors
intrusion. They were randomly selected and divided into two group: anterior miniimplant group (AMG) and posterior mini-implant group (PMG). In the AMG,
approximately 40 g of force was applied per side with elastic chains and in the PMG,
with beta-titanium wires with modification of three pieces intrusive arch. This study
was conducted on cone beam computed tomography scans taken before intrusion
and after 18 weeks of intrusion. Results: The incisors showed a significant reduction
in length, this amount was greater in AMG than PMG. Conclusion: Posterior miniimplants assisted maxillary incisors intrusion show less root resorption than anterior
mini-implant assisted maxillary incisor intrusion
