PURPOSE: Nowadays, checkbite methods and a digital sensor are used to analyze the movement of mandible. However, there are no study comparing two methods. Therefore, this study has compared measuring the condylar inclination methods by using the new ARCUSdigma 2 system and the checkbite method.
MATERIALS AND METHODS: Young 20 adults without any orthodontic treatment experiences, missing teeth, and restorations with the change of occlusal plane were tested. Angles of condylar path were measured 3 times each, based on Camper's line, by using two methods. KaVo PROTAR Evo 7 semi-adjustable articulator was used and the data were statistically analyzed.
RESULTS: 1. The anterior sagittal condylar inclination by ARCUSdigma 2 system were measured as 26.97 degree (±7.38 degree) on the left side and 29.80 degree(±8.19 degree) on the right side. The lateral condylar inclination were measured as 5.75 degree(±3.47 degree) on the left side and 8.10 degree (±4.98 degree) on the right side. 2. The anterior sagittal condylar inclination by checkbite method were measured as 25.20 degree (±6.53 degree) on the left side and 28.18 degree (±7.38 degree) on the right side. The lateral condylar inclination were measured as 10.97 degree (±5.63 degree) on the left side and 12.03 degree (±5.22 degree) on the right side. There was no statistically significant difference between male and female (P>.05). 3. The lateral condylar inclinations of ARCUSdigma 2 were statistically significantly smaller than that of checkbite method (P<.05).
CONCLUSION: In Both of 2 methods, there was no statistically significant difference between male and female (P>.05). However, the lateral condylar inclinations of ARCUSdigma 2 were statistically significantly smaller than that of checkbite method (P<.05).
