However, the exact physiological effects of\n ARS<\/jats:styled-content>\n are still unclear. This study investigated the short and long\u2010term effects of\n ARS<\/jats:styled-content>\n on disc and condyle angles\/positions by metric analysis. Twenty\u2010two subjects diagnosed with\n ADD<\/jats:styled-content>\n wR were recruited. Maxillary full\u2010coverage\n ARS<\/jats:styled-content>\n were fabricated, and\n MRI<\/jats:styled-content>\n of\n TMJ<\/jats:styled-content>\n s was obtained before splint treatment, immediate post\u2010insertion and 6 months after splint treatment. Disc\u2013condyle relationship was determined by disc\u2013condyle angle measurement. Disc and condyle positions were described as X\u2010Y coordinates with the summit of glenoid fossa as the origin of the coordinates. Thirty\u2010two\n TMJ<\/jats:styled-content>\n s were classified as\n ADD<\/jats:styled-content>\n wR and 12 were normal. Upon\n ARS<\/jats:styled-content>\n insertion, all\n TMJ<\/jats:styled-content>\n s with\n ADD<\/jats:styled-content>\n wR got normal disc\u2013condyle relationships. The condyles moved significantly forward and downward, while the discs moved significantly backward and upward.\n MRI<\/jats:styled-content>\n at 6 months after treatment (without\n ARS<\/jats:styled-content>\n insertion) indicated that only 40\u00b76% (13\/32) of the joints were maintained in the normal disc\u2013condyle relationship. The majority of condyles returned to their pre\u2010treatment positions, while the discs generally moved anteriorly again. The use of\n ARS<\/jats:styled-content>\n resulted in forward and downward condyle movement, and a concurrent backward movement of the disc resulting in ideal spatial disc\u2013condyle relationship. The stability of this relationship, however, could not be maintained in the majority of\n TMJ<\/jats:styled-content>\n s upon\n ARS<\/jats:styled-content>\n removal. Findings explain the good short\u2010term clinical outcomes with\n ARS<\/jats:styled-content>\n and their relatively lower efficacy in the long term.\n <\/jats:p>","DOI":"10.1111\/joor.12532","type":"journal-article","created":{"date-parts":[[2017,6,10]],"date-time":"2017-06-10T08:06:39Z","timestamp":1497081999000},"page":"664-672","source":"Crossref","is-referenced-by-count":51,"title":["Physiological effects of anterior repositioning splint on temporomandibular joint disc displacement: a quantitative analysis"],"prefix":"10.1111","volume":"44","author":[{"given":"H.\u2010M.","family":"Chen","sequence":"first","affiliation":[{"name":"Center for TMD & Orofacial Pain Peking University School & Hospital of Stomatology Beijing China"},{"name":"Department of General Dentistry II Peking University School & Hospital of Stomatology Beijing China"},{"name":"National Engineering Laboratory for Digital and Material Technology of Stomatology Beijing China"},{"name":"Beijing Key Laboratory of Digital Stomatology Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.\u2010Q.","family":"Liu","sequence":"additional","affiliation":[{"name":"Center for TMD & Orofacial Pain Peking University School & Hospital of Stomatology Beijing China"},{"name":"National Engineering Laboratory for Digital and Material Technology of Stomatology Beijing China"},{"name":"Beijing Key Laboratory of Digital Stomatology Beijing China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.
