Photoelastic analysis of tension distribution in different orthodontic approaches for closing anterior open bites.

Background: This study aims to evaluate tension distribution in the anterior region of the mandible during two orthodontic mechanical approaches to treat anterior open bite.

Methods: It was an in-vitro experimental study, that analyzed 5 models of photoelastic resin, simulating a lower dental arch. The anterior teeth underwent orthodontic forces of the Blue Elgiloy® 0.

An Alternative Approach for Space Opening in a Bilateral Maxillary Lateral Incisor Agenesis Patient using Miniplates.

Aim: This case report aimed to present an orthodontic mechanic alternative for space opening in a patient missing maxillary lateral incisors, using miniplates as anchorage, associated with self-ligating brackets.

Background: Dental agenesis affects the population causing esthetic and functional damages. The prevalence of missing maxillary lateral incisors should be considered for its significant rate and negative impact on smile esthetics.
