Effect of the presence of orthodontic brackets on intraoral scans.

Objectives: The need for intraoral scanning in the presence of brackets has increased for monitoring tooth movement during orthodontic treatment. The purpose of this study was to evaluate the effect of orthodontic brackets bonded to tooth surfaces on intraoral scans.

Materials And Methods: Intraoral scans were performed in 30 patients using both iTero and Trios scanners before and after bonding of the brackets.

Comparison of the three-dimensional structures of mandibular condyles between adults with and without facial asymmetry: A retrospective study.

Objective: This retrospective study compared the three-dimensional (3D) structure of mandibular condyles between adults with and without facial asymmetry, and whether it influences menton deviation.

Methods: Sixty adult patients were classified into symmetry and asymmetry groups based on the menton deviation on postero-anterior radiographs. The right/left differences of 3D measurements were compared between the two groups, and measurements were compared separately on the right and left sides.
