Predictability of orthodontic tooth movement with aligners: effect of treatment design.

Backgrounds: The present study was designed to define: (1) which are the less predictable OTM with Invisalign aligners when the treatment plan is designed by expert operators, (2) if the presence and shape of attachments influence the predictability of OTM and (3) if patients' demographics influence OTM predictability. The sample comprises 79 prospectively recruited patients (mean age 30.8 years; SD 12.

Chewing pattern before and after unilateral posterior cross-bite therapy with function generating bite: a case report.

Objectives: To evaluate the chewing-cycle closing direction of a patient with a posterior unilateral crossbite, before treatment, six months and one year after correcting the malocclusion with a function generating bite.

Methods And Materials: An 8-year-old girl with right unilateral posterior cross-bite was treated with a function generating bite, which corrected the cross-bite within 5 months. Mandibular movements during mastication of a soft and of a hard bolus were recorded before and after treatment with a K6 I kinesiograph (Myotronics Inc.
