Comprehensive orthodontic-surgical treatment planning for patients with skeletal dentofacial anomalies based on the digital 3D-technologies

OBJECTIVE: To propose and validate a new method of treatment planning for orthodotic-surgical cases based on digital 3D-technologies. MATERIALS AND METHODS: A clinical case is presented demonstrating the planning of comprehensive orthodontic-surgical treatment for a patient with a skeletal form of distal occlusion using the developed method. This method is based on creating a digital simulation model of the dentoalveolar complex by combining medical images of different modalities (CBCT, digital dental arch models) into a single workspace for subsequent virtual surgical and orthodontic treatment simulation as a foundation for later implementation. RESULTS: The method of planning orthodontic-surgical treatment using digital 3D technologies was described and tested on a patient with a skeletal form of distal occlusion. As a result, a sequential simulation of bimaxillary orthognathic surgery and preparatory orthodontic treatment was performed on the digital simulation model of the dentoalveolar complex. CONCLUSION: The digital simulation model of the dentoalveolar complex serves as a basis for virtual simulation of comprehensive treatment by maxillofacial surgeons, orthodontists, and prosthodontists. This technology allows visualization of the treatment outcome before its initiation and reduces the likelihood of complications during the orthodontic and surgical stages of comprehensive treatment. Integration of a patient's digital data and working with it in specialized computer programs with high accuracy enables determination of the necessary extent and biomechanical nuances of tooth movement, as well as monitoring the dynamics of orthodontic treatment.
