Avaliação da viabilidade anatômica do côndilo mandibular para ancoragem esquelética em discopexias

Abstract

There is a wide variety in design and size of anchors for repositioning and stabilizing the temporomandibular joint disc. Despite being a widely publicized treatment in literature, there is no precise study about condylar dimensions in the region where the articular disc of mandibular condyle anchorage is recommended. Thus, the aim of this study is to evaluate the dimensions of mandibular condyle and its feasibility for anchors installing in discopexy. 295 mandibular condyles were analyzed through computed tomography which was performed between 2018 and 2022, and the length of three vectors (AL1, AL2 and AL3) for anchorage was defined. Mandibular condyles without the presence of degenerative diseases presented enough space for the Mitek Mini Anchor 1.8 mm installation. Mandibular condyles presenting tomographic findings had less available space for skeletal anchorage. The bigger amount of tomographic findings means the less available space for mandibular condyle anchorage. It was followed that the AL3 insertion vector is the best option for mandibular condyle anchors installing.
