Computer Program for Digital Data Analysis of Facebow Records – Part І

The purpose of the study is to create computer program for the achievement of precise digital data processing of records performed with the “Facebow Mini-Maxi” and the facilitation of information transfer to the articulator.

Material and method: A conceptual project was developed in order to create a new software product and requirements were defined towards its capacities, which are to provide guidance for its creation. With the assistance of computer programmer, the project was implemented.

Results: The computer program “Facebow Mini-Maxi Analyzer” for digital data processing of registrants performed with the auricular type facebow was created. The program provides automatic recognition, reading, calibration and measurement of data obtained by “Facebow Mini-Maxi”. The main module gives us opportunities for measuring the values of: the sagittal condylar pathway; the arrow point angle and the length of the hinge axis. After finalizing the calculations, the software automatically generates a scheme with visualization of the parameters that significantly supports the dental technician when it comes to defining the accurate position of the models in dental articulator with individual parameters.

Conclusion: The computer program provides accurate analysis of facebow records and assists in determining individual patient movement parameters of the lower jaw. The obtained results from the analysis improve the precision of casts mounting in articulator. The program cuts down the risk of subjective error when analysing the data via manual measurement of the recorded parameters on paper carrier.
