Stress distribution analysis in anterior teeth caused by several retraction mechanics.

Introduction: Orthodontic retraction of the anterior teeth is indicated when the patient has a malocclusion with protrusion of the incisors. Several mechanics are indicated to perform this retraction.

Objective: The objective of this study was to compare the strains generated by four different types of retraction mechanics along the roots of the anterior teeth.

Safe sites for orthodontic miniscrew insertion in the infrazygomatic crest area in different facial types: A tomographic study.

Introduction: Temporary skeletal anchorage devices (TSADs) are used to obtain skeletal anchorage for orthodontic treatment. Their insertion in the infrazygomatic crest (IZC) allows efficient orthodontic mechanics. Different facial types have different bone configurations.

Photoelastic analysis of stress distribution in mandibular second molar roots caused by several uprighting mechanics.

Introduction: Mandibular molar uprighting is indicated when mesial inclination of the second molars occurs because of missing first molars. There are many methodologies to perform such movement. In this study, we aimed to analyze and compare the stress distributions in different molar uprighting techniques.
