ABSTRACT:-
Objectives: This study aimed to assess anchorage loss in central incisors and premolars after maxillary molar distalization with MOPs to accelerate tooth movement. Methods: Thirty class II patients indicated for maxillary molars distalization received miniimplant-supported distal jet appliance and were randomized to receive micro-osteoperforations on the buccal side, buccal and palatal side or no application. Micro-osteoperforations were applied in a repeated manner with each activation of the device. Study casts obtained before and after treatment were laser scanned to obtain 3D digital models. The pre and post-digital models were superimposed according to the same reference points to allow measurement of anchorage loss of central incisors and premolars. Data were analyzed using the one-way ANOVA test for intergroup comparison and the paired t-test for intragroup comparison. Results: No significant differences were found at T4 among the three groups. However, there was statistically considerable anchorage loss in central incisors and 1st premolars (on both sides combined and separate) after maxillary molar distalization in all groups compared to baseline. Conclusion: The application of MOPs on buccal or buccal and palatal sides did not cause considerable anchorage loss compared to no application after maxillary molar distalization. However, the anchorage loss was considerable after treatment.
