C-orthodontic microimplant for distalization of mandibular dentition in Class III correction.

A 16-year-old male patient with a Class III malocclusion and 2 lower missing central incisors presented for treatment. The treatment plan consisted of asymmetrically distalizing the lower dentition and regaining space for lower anterior prosthetic work. C-implants were to be used as anchorage for Class III intermaxillary elastics, and two C-orthodontic microimplants (C-implants) were placed in the interdental spaces between the upper second premolars and first molars. The particular design of the C-implant head minimized gingival irritation during the orthodontic treatment. Sliding jigs were applied on the buccal for distalization of the lower posterior teeth. The correct overbite and overjet were obtained by distalizing the entire lower dentition into its proper position with C-implant anchorage, which contributed to an improvement in facial balance. It took 15 months to treat this case. The application of this new microimplant, considerations for case selection, and the sequence of treatment are presented.
