The process of evaluating the position of the mandible and analyzing occlusion using traditional articulators involved complex and time-consuming laboratory procedures, such as facebow transfer and model mounting. These methods often faced challenges with reproducibility, leading to difficulties in accurately assessing a patient’s occlusion. This paper aims to present a technique for precise evaluation of the mandible position and the patient’s occlusion, achieved through the utilization of virtual articulators and virtual MPI (Mandibular Position Indicator), leveraging digital data to overcome these constraints. The use of virtual articulators allows for a convenient and accurate simulation in the program, entirely circumventing the need for intricate laboratory procedures. By leveraging digital data to create a virtual articulator and accurately evaluate a patient’s occlusion, it becomes feasible to formulate a treatment plan based on this evaluation, resulting in successful orthodontic treatment. Digital transformation refers to the process of upgrading, enhancing, or replacing existing processes or systems with newer ones, facilitated by advancements in digital technology. The most crucial principle in the process of digital transformation is that it should be simpler and more accurate than the traditional analog methods. In the process of digitally transforming the occlusal evaluation, it is essential to first understand the principles of the procedures performed with the conventional analog articulators and then integrate them into the digital transformation. Therefore, this article aims to introduce how virtual articulators and virtual mandibular position indicators are utilized.
