The process of evaluating the position of the mandible and analyzing occlusion using traditional articulators involved com-plex 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 or-thodontic 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.

The treatment of constricted anterior arch in adult patients is challenging for orthodontists because transverse correction of maxillary arch requires surgical approach and transversal change interacts with vertical and sagittal changes correspondingly. This case report introduces a nonsurgical treatment of adult patient with constricted anterior arch and unilateral scissors bite. The anterior maxillary expansion was obtained by rapid palatal expansion (RPE) without the use of mini-implants. Semi-fixed anterior bite plate was used for deep bite correction, and it resulted to spontaneous mandibular expansion. The patient was satisfied with the successful nonsurgical orthodontic treatment which showed favorable occlusion and harmonious facial profile.

In cases where anterior open bite is accompanied by maxillary posterior extrusion, it is necessary to apply orthodontic force for maxillary posterior intrusion during non-surgical treatment. Utilizing skeletal anchorage for maxillary posterior intrusion allows for non-surgical correction of anterior open bite, providing an aesthetically pleasing outcome without side effects such as unwanted extrusion of other teeth. This case report presents the non-surgical treatment of a skeletal anterior open bite patient, a 22-year-old woman, by applying maxillary posterior intrusion using mini-implants and incorporating the use of a Multi-Loop Edgewise Arch Wire (MEAW). The report also includes a two-year follow-up after treatment. The patient presented with anterior open bite, which was successfully corrected through maxillary posterior intrusion. Additionally, tongue exercises were performed during and after orthodontic treatment to correct tongue thrusting habits. During a follow-up visit two years after treatment, although there was a slight decrease in overbite, the occlusion remained stable, indicating a still successful and stable outcome.
