Sažetak
Purpose Articular eminence (AE) morphology could be expressed by dimensions and angles measured by different methods. The aim of this study was to compare conventional two-dimensional with three- dimensional laser method. Materials and Methods The study was carried out on 20 human dry skulls (18 to 65 years) from medieval and contemporary period. Measurements were performed on sections (real and virtual) through the AE silicone impressions (lateral-medial) using two-dimensional and three-dimensional (laser) digitalization. AE inclination (two methods) in relation to the Frankfurt horizontal, AE height and the length of curved line (highest to the lowest AE point) were measured. Results were statistically analyzed with significance level of 0.05. Results Although small differences existed between AE measurements performed by conventional and three-dimensional laser technology, most of obtained differences were not statistically significant (p values: AE inclination 0.003 to 1.0 ; AE height 0.012 to 1.0 ; curved line length of 0.115 to 1.0). Differences between AE inclination values measured by “best fit line” method and “fossa roof – eminence top” method were statistically significant (p<0.001). Conclusions Silicone impressions eased the procedure and retained accuracy for AE measurements. Differences for most of the performed measurements by conventional and three- dimensional method were not significant, thus indicating same reliability of the used methods. AE values by „best fit line“ method were higher than by „fossa roof–eminence top“ method no matter which measuring method was used. These values are more affected by the eminence height thus representing simplified but actual condylar path significant for adjustment of articulators.
