Abstract:
Temporomandibular joint (TMJ) is a hinge joint that connects the maxillary and mandibular bones between the head of the mandibular condyle and the temporal bone. Removing premolars can cause Temporomandibular Disorder (TMD) which is still debated due to diagnostic errors or errors in mechanotherapy during treatment. Most of the literature states that there is no scientific evidence that premolar removal is a risk for TMD. However, orthodontists should still be aware of anterior tooth contact during orthodontic treatment due to incisor retroclination, deepening of the bite, and incisal interference. The use of low force is still the mainstay for anterior retraction so that there is no decrease in vertical dimension due to loss of anchorage. Achieving the centric relation is the ideal goal of orthodontic treatment, so determining the pre-treatment centric relation is essential. Orthodontic treatment generally tends to improve rather than worsen TMJ conditions.
Purpose: This study aims to describe changes in the TMJ and masticatory muscles after orthodontic treatment with premolar extraction.
Conclusion: Several studies have shown no significant difference in masticatory muscles before and after orthodontic treatment with extraction.
