“…Thilander groups observed that TMDs were significantly associated with posterior crossbite, and suggested that malocclusions should be treated orthodontically in an early age to protect against TMD [ 33 ]. In contrast, Al-Ani and Špalj et al found that symptoms of TMDs seemed to be poorly related to malocclusions [ 34 , 35 ]. Although the evidence available does not allow to establish a unambiguous relationship between malocclusions and TMD, the effects of malocclusions in growing patients of TMDs deserve further investigation.…”

Background The purpose of the present study is to evaluate the prevalence of temporomandibular disorders (TMD) and their associated biological and psychological factors in Chinese university students. Methods A total of 754 students were included from Zunyi Medical University, each participant completed questionnaires and clinical examinations according to the Diagnostic Criteria for Temporomandibular Disorders. Results The overall prevalence of TMD was 31.7% among medical students. Subjects with TMD had a high prevalence of bruxism, empty chewing, unilateral chewing, chewing gum, anterior teeth overbite, anterior teeth overjet, depression, anxiety, and sleep disturbance. Moreover, sleep bruxism, empty chewing, unilateral chewing, anterior teeth overbite, depression, and anxiety were the strongest risk factors for TMD. Conclusions Individuals with TMD have a high prevalence of psychological distress and oral parafunctional habits. Except for the psychological factors associated with TMD, bruxism, abnormal chewing, and malocclusion also shared similar risks for TMD.

“…Other considerations indicate that remodeling capacity within the masticatory system facilitates adaptation to most occlusal functions and dysfunctions [ 6 ]. It seems to mirror the non-linear dynamics of a stress/strain curve, which is dedicated to tensegrity and living tissues [ 24 ].…”

“…The relationship between dental occlusion and temporomandibular disorders (TMDs) still remains controversial, inconclusive, and not fully examined [ 5 , 6 , 7 ]. Currently, etiological factors are based mainly on behavioral, psychological, and neurological components [ 6 ]. Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) provide an appropriate, valid, and reliable clinical tool to perform differential diagnosis with respect to physical and biopsychosocial condition (Axes I and II, respectively) [ 5 , 8 , 9 , 10 , 11 ].…”

The aim of the study was to evaluate occlusal parameters in patients with myofascial pain with referral before and after soft tissue mobilization. The study group consisted of 50 people (37 females and 13 males, average age 23.36 ± 2.14 years) diagnosed with myofascial pain with referral. All patients underwent triplicate soft tissue mobilization. Occlusal parameters were evaluated six times, before and after each treatment, using T-scan III. A decreasing tendency of the occlusion time was observed after the first, second, and third therapy. After the third treatment, the mean occlusion time in the entire study group was 0.119 s. The 1st soft tissue mobilization shortened both right and left disclusion times to 0.181 s and 0.185 s, respectively. After the third treatment, these parameters amounted to 0.159 s and 0.165 s, respectively. The Friedman test for the entire study group indicated that soft tissue mobilization altered the occlusion time and both disclusion times (p < 0.05). In conclusion, soft tissue mobilization affects biotensegrity of the masticatory system, thus modifying occlusal parameters. The occlusion time and both disclusion times cannot be considered as cofactors of the existing temporomandibular disorders—myofascial pain with referral.

“…Generally, there is insufficient evidence to suggest that any occlusal treatment is as effective, or more effective, than any other rehabilitation treatment in TMD. 50…”

The symptoms of TMJ Osteoarthrosis/Osteoarthritis(TMJ OA) are characteristic and in most cases specific to the disorder. There is, however, an overlap of symptoms with other TMDs. Treatment of TMJ OA is generally directed towards management of the symptoms as the temporomandibular joint does retain the capacity throughout life to repair and remodel. Non-conservative and invasive treatment is only rarely necessary. It should be remembered that the mandibular condyle retains the capacity to repair and remodel throughout life and patients should be encouraged to bear this in mind. Conservative measures are usually sufficient to treat symptoms and a period of time should be allowed to elapse before undertaking a more aggressive treatment plan, which, in the overwhelming majority of patients, will not be necessary. This disorder should be approached on the terms of ‘a quality of life issue’ and treatment should be directed towards patient needs.
