Comparison of two different digital occlusal analysis methods.

Abstract

The aim of this study is to compare the sensitivity of T-Scan digital occlusal analysis system and the occlusal analysis mode of the CEREC Omnicam system, which is mainly used for design/production, using the data recorded at the maximum intercuspal position. Occlusal recordings were obtained from healthy20 females and 20 malesaged 18-25 at the maximum intercuspal position. Records were saved as.jpeg format and transferred to Adobe Photoshop CS6 program. Blue, green, and red colors (shown by the same color codes in both systems) representing light, intense, and tight contacts, respectively, were evaluated in terms of the pixel counts. For statistical comparison, the differences between the systems independent sample T test and, between the genders, one sample T test were used (α = 0.05). The total numbers of pixels of all colors which are evaluated with T-Scan and CEREC Omnicam in females were 31,296.6 and 15,745, respectively, and in males 39,812.3 and 17,462, respectively. In both systems, the blue contact area is the most seen. For all colors tested, T-Scan recorded more contact than those of CEREC Omnicam in both genders and statistically significant difference was found between two systems for all colors. In both systems, recorded contacts are significantly higher in men than in women. Compared with women, 27% more contact area was recorded in men with T-Scan and 11% more with CEREC Omnicam was obtained. While T-Scan was found sensitive even in the diagnosis of light contacts, the CEREC Omnicam was found sensitive only in the diagnosis of tight contacts. Although both T-Scan and CEREC Omnicam are effective in occlusal analysis, T-Scan's sensitivity was found to be higher. ClinicalTrials.gov identifier: NCT04798729.
