Relationship between Mediotrusive Occlusal Contacts and Temporomandibular Disorders in Young Adults without Psychosocial Disorders: A Case-Control Study.

Similarly, other publications consider that these contacts during laterality, more than other occlusal factors, have some degree of association with articular and muscular disorders.[ 5 , 10 , 24 , 25 , 26 ] However, it has been reported that this relationship is not clinically significant for chronic TMD symptoms, but may be significant for acute transient symptoms.[ 10 ] Studies with electromyography demonstrate that alterations in occlusal contacts may change the pattern and produce painful symptoms at the level of the masticatory muscles,[ 27 , 28 ] but other studies find that the changes are not significant in relation to non-working side contacts.[ 29 , 30 ] This is due to resilience and tissue accommodation phenomena or contact wear due to increased mobility between teeth, which explains most cases with the absence of TMDs symptoms and in others, the presence of acute symptoms.
