Sažetak
The purpose of the study was to record and measure the lengths of protrusive and retrusive mandibular paths. Protrusive movements of 30 subjects were analysed: 15 subjects with craniomandibular dysfunction symptoms and 15 asymptomatic subjects. Out of this number, 8 were male and 22 female, ranging from 18 to 57 years. With the aid of diagnostic computer software, the length of the protrusive and retrusive path of jaw joint condyles was recorded and measured. The lengths of protrusive and retrusive movements in the right joint for the symptomatic and asymptomatic group ranged from 6.36 to maximally 13.86 mm. For the left joint these values were from 6.32 to 15.86 mm. A statistical analysis based on T-scan of both samples was conducted. The aim of the statistical analysis was to find a significant difference in the length of protrusive and retrusive mandibular paths in symptomatic and asymptomatic subjects. T-scan of independent samples did not establish any statistically important difference in the length of protrusive (or retrusive) movement paths between the group of asymptomatic and symptomatic subjects. On the contrary, T-scan of dependent samples established a statistically important difference in the length of protrusive (or retrusive) movement paths between the right and left joint in the symptomatic subjects. The results of the study confirm the possibility of using electronic axiography for early detection and diagnosis of craniomandibular dysfunctions.
