[Relationship between temporomandibular disorders and malocclusions: from history to present].

Regarding the relationship between malocclusions and temporomandibular disorders (TMD), from the leading cause to one of the local biological factors, the change in the understanding of the academic community since the 1980s has affected the clinical diagnosis, treatment behavior, and the direction of scientific research. At present, it is believed that the etiology of TMD is multifactor. The occlusal factors and the occurrence of TMD are weakly related, but there are some common malocclusions such as occlusal interference on non-working side, excessive sliding between maximum intercuspid position (MIP) and retruded contact position (RCP), unstable MIP and so on, may be risk factors that promote the disease. The occurrence of TMD symptoms is promoted under the combined action of behavior, biology, environment, social cognition, mentality and other comprehensive factors. In student education and clinical work, the risk of iatrogenic occlusal trauma in promoting the occurrence of TMD cannot be ignored. The impact of the patient's social and psychological environment on the TMD should be paid attention, and comprehensive treatment strategies is advocated.
