This study introduces a new electronic instrument for precise condylar position analysis. It enables accurate, repeatable measurements for clinical use and future comparisons.

Area of Science:

Dentistry
Biomedical Engineering
Medical Instrumentation

Background:

Condylar position analysis is crucial for understanding mandibular dynamics.
Traditional methods lack precision for comparative, longitudinal studies.
Advancements in 3D imaging aid surgical planning but not routine comparative analysis.

Purpose of the Study:

To develop an electronic measuring instrument for accurate condylar position acquisition in clinical settings.
To enable reliable comparative measurements of condylar position over time.
To integrate data storage and precise calibration for longitudinal studies.

Main Methods:

Design and implementation of a novel electronic measuring instrument.
Utilized existing components from Reference CPM and Cadiax Compact systems.
