A comparison of second premolar extraction and mini-implant total arch distalization with interproximal stripping

Abstract

Objective: The effect of total arch distalization using orthodontic mini-implants (OMIs) combined with interproximal stripping (IPS) and second premolar extraction was investigated in Class I malocclusion patients. Materials and Methods: A total of 66 consecutively treated Class I malocclusion (Class I molar relationship; 0 mm , overbite and overjet , 4.5 mm) patients ranging in age from 17 to 44 years who received single-phase treatment were included in this study. Pre-and posttreatment lateral cephalograms and dental casts were measured and compared statistically. Results: In the distalization with IPS group, 3.6 mm and 3.8 mm of crowding in the upper and lower arches, respectively, were resolved, and 3.8 mm and 3.2 mm of upper and lower incisor retraction, respectively, were achieved simultaneously by the treatment. As a result of the second premolar extraction treatment, 3.9 mm and 3.6 mm of crowding in the upper and lower arches, respectively, were resolved, and 3.3 mm and 3.2 mm of incisor retraction, respectively, were achieved during treatment. There was no statistically significant difference in the amount of crowding and incisor retraction between the two groups. Conclusions: Total arch distalization using an OMI with IPS did not yield a significantly different treatment result compared to second premolar extraction treatment.

Correction of severe bimaxillary protrusion with first premolar extractions and total arch distalization with palatal anchorage plates

“…21,22 Recently, the treatment results of total arch distalization using miniscrews have not been significantly different from those achieved by second premolar extraction treatment in resolving crowding and retracting the anterior dentition. 23 Also, Choi et al 3 reported successful total arch distalization using skeletal anchorage in Class II malocclusion patients. They placed 5 miniscrews during the treatment procedures and achieved the results with a 2-step technique starting with the distalization of the second molars, followed by the rest of teeth.…”

“…6,7 Distal retraction of the whole dental arch using miniscrews was recently published and showed good treatment results. 6,8,9 The distalization force is usually applied to the canines or hooks attached on the archwire from miniscrews placed between the roots of the posterior teeth.…”
