Clinical implementation of axial angulation of incisors in the course of routine fixed appliance treatment - a retrospective cohort study.

ABSTRACT:

Purpose

To identify clinically relevant factors for changes in axial angulation of incisors during routine fixed appliance orthodontic treatment.

Methods

A total of 106 patients (grades 1-2 of IOTN, 64 females, 42 males; mean age: 15.5 years) from a private practice and treated with metal or ceramic brackets were included in this retrospective cohort study. The axial angulation of the upper and lower incisors was measured on lateral cephalograms before insertion of the first rectangular 0.016 × 0.022-in NiTi archwire (T0) and at the end of treatment about 8 weeks after insertion of the working 0.019 × 0.025-in stainless steel archwire (T1). Treatment-related changes according to bracket type, initial situation, premolar extraction, angle class, and skeletal vertical configur
