CLINICAL APPLICATION OF 3D TECHNOLOGY FOR PLANNING DENTAL AUTOTRANSPLANTATION SURGERY

Digital technology has become an integral part of both the social and medical components of modern life. Dentistry, as a branch of medicine, most actively uses the capabilities of additive manufacturing to achieve a successful outcome, ensuring the coincidence of the expected and final treatment results, minimizing the risk of conflict situations, litigation procedures and unfavorable outcomes. New opportunities are offered by digital technology in the planning of dental autotransplantation and replacement of defects arising after tooth extraction. The developed algorithm for creating a personalized dental model increases the efficiency of the transplantation surgery, restores the integrity of the dentition and prolongs the graft’s service life and physiological functioning of the graft. To achieve this goal, a comprehensive digital planning with the 3Diagnosys computer software (Italy), being presented as a tool for visualization, diagnostics and 3D modeling.

In addition, we carried out the visual examination of the oral cavity, index assessment of the state of periodontal tissues, structural analysis of the bone tissue of the donor and recipient zones using computed tomography, the formation of a virtual image of the graft and its digitization, followed by objectification using 3D printing technology using resin polymers used for work in the oral cavity. The ultimate goal of creating a template is the formation of the spatial parameters of the tooth bed at the site of the defect to be replaced with the subsequent immersion of the transplanted tooth. Long-term results demonstrate the absence of pain and inflammatory reactions, stability in the transplantation area allowing us to recommend this algorithm as an improved method of autotransplantation surgery. This technique is the method of choice in a particular clinical situation and can be used depending on the indications.
