Limitation of mouth opening, defined as a decrease of inter\u2010incisal distance, appeared in 19 participants (22.6%) and in 25 participants (29.8%) measured instrumentally with the Arcus Digma device. A comparison of instrumental result examinations of the right and left TMJs showed positive correlations of the range of mandible opening movement with the Posselt opening movement (r = 0.75) and opening\/closing movements with the Posselt closing movements (r = 0.70). A correlation was demonstrated (r = 0.81) between the condylar range of motion studied on the left and on the right TMJ during mandible opening movement. Correlations were also found between opening\u2010closing movements and the condylar range of motion of the left TMJ, and between the opening\u2010closing movement and the condylar range of motion of the right TMJ during the opening movement.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>According to the results of this study with instrumental Arcus Digma ultrasound device measurements of mandibular movements, data were provided on irregularities in TMJ function not detected in participants with or without clinical symptoms of TMD.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/jopr.12389","type":"journal-article","created":{"date-parts":[[2015,10,21]],"date-time":"2015-10-21T10:22:59Z","timestamp":1445422979000},"page":"123-128","source":"Crossref","is-referenced-by-count":49,"title":["Evaluation of Mandibular Movement Functions Using Instrumental Ultrasound System"],"prefix":"10.1111","volume":"26","author":[{"given":"Anna","family":"S\u00f3jka","sequence":"first","affiliation":[{"name":"Department of Prosthodontics University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juliusz","family":"Huber","sequence":"additional","affiliation":[{"name":"Department of Pathophysiology of Locomotor Organs University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"El\u017cbieta","family":"Kaczmarek","sequence":"additional","affiliation":[{"name":"Department of Bioinformatics and Computational Biology University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wies\u0142aw","family":"H\u0119dzelek","sequence":"additional","affiliation":[{"name":"Department of Prosthodontics University of Medical Sciences  Pozna\u0144 Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,10,21]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"234","article-title":"Evaluation of mandibular movement and range of motion in the diagnosis of craniomandibular disorders","volume":"4","author":"Crandall JA","year":"1986","journal-title":"J Craniomandibular Pract"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2005.04.023"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2842.1998.00198.x"},{"key":"e_1_2_6_5_1","first-page":"101","article-title":"Studies on function and dysfunction of the masticatory system.
