Oral appliance therapy vs. positional therapy for managing positional obstructive sleep apnea; a systematic review and meta-analysis of randomized control trials.

Aim: To assess the efficacy of positional therapy and oral appliance therapy for the management of positional obstructive sleep apnea.

Methods: We searched PubMed, Web of Science, Cochrane, and SCOPUS for relevant clinical trials. Quality assessment of the included trials was evaluated according to Cochrane's risk of bias tool.

Predicted and actual outcome of anterior intrusion with Invisalign assessed with cone-beam computed tomography.

Introduction: The purpose of this study was to compare predicted anterior teeth intrusion measurements with the actual clinical intrusion measurements using cone-beam computed tomography. Understanding the precision of the software in anticipating changes may help practitioners predict the need for overcorrection.

Methods: Twenty-two patients, with a mean age of 23.
