- Abstract
CMDs (craniomandibular dysfunctions) are functional disorders that involve the temporomandibular joint (TMJ) and masticatory muscles, but also cause different symptoms in other regions of the body. The role of occlusion is considered as a predisposition or as a contributing factor by initiating the disorder. This study aimed to analyze if there are specific CMD signs and symptoms related to the complexity of orthodontic malocclusion and to identify patients with a risk of developing a CMD before orthodontic treatment is initiated. The study sample consisted of 30 orthodontic patients who were divided in two groups according to KIG (Kieferorthopädische Indikationsgruppen), which has five severity grades. The first group included mild malocclusions (KIG 1 and 2), and the second group included pronounced and severe malocclusions (KIG 3, 4, and 5). Frontal face, profile, cephalometric, and study cast model analysis together with manual and instrumental functional analysis were performed to reveal latent CMD signs and symptoms and to compare these findings with the severity of malocclusion. Of the overall examined patients, 46.67% demonstrated a positive screening. It was more pronounced (26.67%) in the group of mild malocclusions (KIG 1 and 2) compared with the group of pronounced and severe malocclusions (KIG 3, 4, and 5), in which the positive screening was found in only 20% of subjects. No statistically significant association was found between the groups with and without CMD, regarding skeletal jaw discrepancies in sagittal and vertical, the inclination of the maxillary and mandibular incisors, and also regarding the width and the length of the dental arches. The results of this study showed that pronounced malocclusions have a more deranged dynamic occlusion and centric relation. CMD manual functional screening did not show a significant difference between the two study groups (KIG 1,2 and KIG 3,4,5). Patients with slight orthodontic anomalies have the same risk of developing CMD as the patients with severe malocclusions.
