A study of the relationship between lateral guidance and temporomandibular joint internal derangement.
The aim of this study was to examine the relationship between lateral retrusive and lateral protrusive tooth guidance and temporomandibular joint disc displacement. The control group comprised 55 symptomless students and dental nurses. The patient group consisted of 117 patients (90 women and 27 men). Fifty-four patients had temporomandibular joint clicking on the right side and 63 patients had clicking on the left side. The incidence of ipsilateral lateral retrusive tooth guidance was significantly higher in the patient group (87%) than in the control group (18.5%).
