Assessment and Treatment of Occlusion by Orthodontists

Abstract

Unlike corrective and prosthetic treatment of occlusions, orthodontic treatment generally involves reconstruction of the entire temporomandibular joint. Such treatment is characterized by change and adaptation of the mandible and neurocranium associated with occlusal changes. Particularly in young individuals, the adaptation may be used for treatment; however, inappropriate occlusal change is likely to induce dysfunction. In this context, mandibular position is important. The outcome of orthodontic treatment appears to depend on whether or not the mandibular position is carefully examined. First, location of the mandible (therapeutic reference position) is important, because the direction and distance of tooth movement depends on the mandibular position at which occlusion is established. It is difficult to assess the mandibular position, and thus dysfunction is examined by cephalometric analysis and functional analysis, and with the use of a SAM articulator, mandibular position indicator (MPI), CADIAX, etc. At our clinic. In addition, many malocclusions can be corrected when skeletal malocclusion is evaluated in relation to the vertical dimension with consideration of the relationship to the cranial base. Some articles report that more than 30% of adults had disk displacement. It appears to be important to establish functional occlusion not only for aesthetic aspects, but also as a goal of individual orthodontic treatment.
