Maxillary incisors and molars with conventional and skeletal anchorage device: A randomized controlled trial

Effect of traditional anchorage techniques and new mini-implant methods on the positioning of maxillary incisors and molars in terms of anteroposterior, vertical and angular changes is of interest. Hence, eighteen patients, with either Angle Class II Division 1 malocclusion or Class I malocclusion with a bimaxillary protrusion, were split into two groups: Group 1, which used mini-implants and Group 2, which relied on conventional anchorage. Space was closed within 12-18 months and the lateral cephalograms and orthopantomograms (OPGs) were taken at the start (T1) and after space closure (T2). In Group 1, significant movement of the maxillary first molars in both a distal and intruding direction into the bone was observed. Meanwhile, the molars in Group 2 were shifted mesially and extruded. Molar tipping was more stable in Group 1. Mini-implant anchorage proved more efficient in controlling molar movement, retraction and anterior teeth tipping.
