What is Maximum Intercuspal Position (MIP)

This chapter discusses chronic Occluso-Muscle Disorder, which is a myogenous subset of Temporomandibular Disorder symptoms resultant from occlusally activated muscle hyperactivity. Published T-Scan-based research since 1991 has determined that a significant etiologic component of Occluso-Muscle Disorder is prolonged (in time) occlusal surface friction that occurs between opposing posterior teeth during mandibular excursions. This friction results in prolonged compressions of the Periodontal Ligament fibers of the involved teeth, which triggers excess muscle contractions within the masticatory muscles. This chapter describes the neuroanatomy of how the excursive friction induces masticatory muscle hyperactivity and illustrates the patient occlusal factors that promote prolonged occlusal surface friction. It explains the patient section criteria for determining if an Occluso-Muscle Disorder patient is a candidate for occlusal intervention, details the computer-guided Occluso-Muscle Disorder treatment known as Disclusion Time Reduction, and supports this measured occlusal treatment with the research studies that validate using this highly effective Occluso-Muscle Disorder therapy.
