Comparison of orthodontic tooth movement between adolescents and adults based on implant superimposition.

ABSTRACT:

Objective

We compared tooth movement under maximum anchorage control with mini-screw implants in growing and non-growing patients.

Methods

In total, 15 adolescent (G1) and 19 adult (G2) patients with prognathic profiles were selected. All patients underwent first premolar extraction treatment with mini-screw implants for maximum anchorage control. Cone-beam computed tomography (CBCT) data were obtained immediately after implant placement (T1) and at the end of anterior tooth retraction (T2). Tooth movement and root length changes of the maxillary first molar, canine, and incisors were evaluated with three-dimensional models constructed using CBCT data obtained before and after orthodontic retraction through the superimposition of stable implants.

Results
