  • Temporomandibular disorders (TMD)

    A collection of medical and dental conditions affecting the temporomandibular joint (TMJ) and/or muscles of mastication and other contiguous tissue components. Includes myofascial pain‐dysfunction syndrome (MPD), meniscal displacement with or without reduction (internal derangement), degenerative joint disease (osteoarthritis), rheumatoid arthritis, and other disorders of systemic origin, facial growth disharmonies, traumatic injuries, and neoplasms.  

  • Temporomandibular articulation

    Ginglymoarthrodial‐type articulating joint involved in the bilateral connection of mandibular condyles to the temporal bone. Anatomic structures comprising the joint are the anterior part of the glenoid cavity of the temporal bone, its articular eminence, and the mandibular condyle; the ligaments supporting the joint are the temporomandibular, capsular, sphenomandibular, stylomandibular, and articular disk or meniscus.…

  • Telescopic crown

    A secondary or artificial crown that fits over a fixed or nonremovable prosthesis, such as a primary crown, coping, bar, or any other suitable rigid support for the dental prosthesis.  

  • Telescopic coping attachment system

    Retentive mechanism that employs a frictional fit between the matrix and patrix components. External surface of the patrix mirrors the internal surface of the matrix and fits within the confines of the matrix for a frictional, passive fit.  

  • Telescopic coping

    A thin cast cover fabricated for a prepared tooth or implant abutment, which acts as an undersubstructure for a prosthesis.  

  • Telangiectasia

    Telangiectasia

    Permanent dilation of blood vessels near the surface of the skin or mucous membranes that results in small focal red lesions that are commonly seen on the nose, cheeks, and chin. Also called angioectasias or spider veins. A condition in which the small blood vessels, especially in the face and thighs, are permanently dilated producing…

  • Teflon compression ring

    Prosthetic component made of polyoxymethylene intended to provide resilience between the implant and the prosthesis. This ring is placed between the transmucosal element and the prosthesis.  

  • Team approach

    Multidisciplinary combination and collaboration of care and/or therapy providers in the restorative management of a patient whose treatment involves dental implants.  

  • TCP (abbrev)

    Tricalcium phosphate.  

  • Taurodontism

    A variation in tooth form affecting some or all of the primary and secondary molars, marked by elongation of the body of the tooth so that the pulp chambers are large apicoocclusally and the roots are reduced in size. A condition in which the teeth have greatly enlarged and deepened pulp chambers that encroach on…
