Biomechanical performance of ATOZ expander: Finite-element analysis.

Introduction: Microimplant-assisted rapid palatal expansion appliances have been used for the treatment of orthodontic patients with maxillary deficiency. A new design named ATOZ (applicable from A to Z) was recently introduced to expand the scope of treatment in early permanent dentition. The objective of this study was to analyze the biomechanical performance of the ATOZ expander with various microimplants configurations using finite-element method.

Hyoid Bone Position and Upper Airway Morphology of Children With Obstructive Sleep Apnea: A Systematic Review and Meta-analysis.

The objective of this systematic review was to summarise the existing evidence regarding hyoid bone position and upper airway morphology of children with obstructive sleep apnea (OSA). Electronic searches were carried out in PubMed, Embase, Web of Science, CINAHL and WorldCat databases without any restrictions on language from inception to March 2024. The studies which compared the hyoid bone position and upper airway morphology using lateral cephalograms between children with and without OSA will be included.

In-silico evaluation of orthodontic miniscrew-assisted rapid palatal expanders for patients with various stages of skeletal maturation.

Introduction: This study aimed to use a finite element method to assess the stress on the miniscrews, skeletal and dental changes resulting from maxillary expansion using either a tooth-bone-borne (TBB) or a bone-borne (BB) device on patients with various skeletal maturation.

Methods: Two types of expanders were modeled using SolidWorks. The design of the 2 expanders was similar, with the exception that the BB appliance lacked support for teeth (rods and bands).
