“…From a biomechanical point of view, a single unilateral contact on the mediotrusive side may cause a levering action on the mandible (lever class II). In this situation, the contralateral TMJ is theoretically most likely to be affected (Christensen & Rassouli, 1995). It also seems logical that a contact on the mediotrusive side, simultaneously with a contact(s) on the laterotrusive side, would imply a reduced levering action on the mandible.…”

Many opinions have been presented in the literature during the past century regarding so-called mediotrusive/balancing/non-working side contacts. During the first half of this century, most authors advocated the advantage of these contacts (it was more or less the state of the art in prosthetic treatments), while during the last 50 years mediotrusive side contacts/interferences have mostly been regarded as a disturbing factor in the functioning of the mandible. Recently, it has been proposed that mediotrusive side contacts have a protective effect on the temporomandibular joint (TMJ). The aim of this study was to review opinions advocated during the twentieth century regarding the advantages and disadvantages of having contacts on the mediotrusive side during lateral excursions of the mandible. We conclude that, at present, there is no uniform body of scientific evidence supporting a balanced occlusion in favour of a mutually protective occlusion or vice versa. Longitudinal studies based on cohorts with different types of occlusal contacts, estimating the risk among these of developing signs and symptoms of temporomandibular disorders, are generally lacking and could provide valuable knowledge in this field.

“…A TMD patient has pain/ discomfort in the jaw, mainly in the region of the TMJ and/or muscles of mastication, and limitation of mandibular function. [4][5][6][7] These patients can be managed with nonsurgical therapies, but some end-stage TMJ patients require surgical TMJ repair or reconstruction. A multifactor etiology for TMD is proposed.…”

“…Occlusal forces acting on a bolus generate reaction forces in the temporomandibular joints and these are influenced by the position of the occlusal force. In the absence of tooth contacts, these reaction forces will always be compressive on the mediotrusive side as the condyle is the fulcrum of a class I lever system 30,31 . However, they can vary from compressive, to neutral to tensile on the ipsilateral side as the occlusal force moves distally 32 .…”

Purpose The impact of mediotrusive (MT) occlusal contacts has been a topic of controversy and confusion in both clinical practice and in the dental literature. The purpose of this Best Evidence Consensus Statement was to explore whether MT interferences are harmful in the natural or therapeutic occlusion directed by 4 focus questions relating to prevalence, jaw function, jaw dysfunction and biomechanical models. Materials and Methods An electronic search in October 2020 sought evidence in MEDLINE (Ovid) using (mediotrus* OR nonworking side OR nonworking contact OR balancing side OR interfer* side OR premature contact) in the multipurpose (.mp) search field; and in Google Scholar using permutations of the above. Supplementary articles were sourced from the associated reference lists. There was no language restriction. The search yield was reviewed in duplicate. Results The electronic search identified 420 articles. Following screening, 164 were selected for eligibility assessments. Of these, 47 were included in the current paper. Conclusions Non‐standardized nomenclature and methodology is used to identify MT interferences in patient populations, with resultant prevalence varying from 0% to 77%, (median = 16%). MT interferences may alter the biomechanics of mandibular function. Together with the presence of repeated high loads resultant strain can manifest as pathophysiology of the temporomandibular joint and associated muscle structures. MT interferences should be avoided in any therapeutic occlusal scheme to minimize pulpal, periodontal, structural and mechanical complications or exacerbation of temporomandibular disorders (TMDs). Naturally occurring molar MT interferences should be eliminated only if signs and symptoms of TMDs are present. Literature supports there being a biomechanical basis which can explain how MT interferences may affect temporomandibular joint morphology and jaw function.
