“…The central position is fi xed onto the top of the arrow point angle, as the position defi ned in this way coincides with the central relation [7]. The accuracy of pre-articulation steps, such as impressions, interocclusal records, and facebow transfers, is very important [18,19,20]. If inaccuracy occurs at any stage of the dental cast mounting procedure, the dental prosthesis would not fi t functionally [5].…”

The aim of the study was to perform a comparative data analysis of the values of sagittal condylar path and arrow point angle, obtained through measurements based on facebow records, by applying two methods: manual and digital by using the Mini-Maxi Facebow Analyzer computer program.Material and method: The program was tested through processing the data of 101 subjects (52 men and 49 women). The left and right sagittal condylar path was registered by using the Mini-Maxi facebow and the mandibular central position was determined by intraoral graphic registration. The data of each subject were entered into the program and the individual values of the registered parameters were calculated. Then, a comparative statistical analysis of the data obtained by the conventional manual measurement with a protractor and the computer program was performed.Results: The mean value of the sagittal condylar path obtained through the computer program was 34.89˚ for the right side and 35.86˚ for the left side. The mean value of the arrow point angle obtained through the computer program was 107.52˚. The differences between the data for men and women were not statistically significant (р < 0.05).Conclusions: The computer program provides an accurate analysis of facebow records and assists in determining individual patient’s movement parameters of the lower jaw. The comparative analysis of the accuracy of parameters obtained through conventional and digital measurements demonstrates the high product reliability of the computer program.
