DENTAL IMPLANTATION AFTER RECONSTRUCTION OF TOTAL AND SUBTOTAL DEFECTS OF THE UPPER AND LOWER JAWS

Medical and social rehabilitation of patients with total jaw defects is an urgent surgical problem for maxillofacial surgeons. Cicatricial deformities, functional disorders of anatomical structures after resection are a difficult task for reconstructive surgery. It is impossible to achieve positive results without the use of digital technologies, a review of the methods of «digital dentistry» (CAD-CAM modeling and 3D printing) on clinical examples.

The aim of the study was to investigate the necessity of using digital technology in prosthetic patients with subtotal and total jawbone defects.

Materials and methods. The review provides examples of complex dental rehabilitation of patients with a detailed description of clinical and laboratory procedures, photographs and X-ray studies.

Results. An illustrative clinical example confirms the high value and significant role of computer simulation in complex clinical cases and situations. The presented technique made it possible to restore the former quality of life of patients, which indicates its high development today.

Conclusions. Clinical examples confirm the effectiveness of the use of digital dental technologies, prosthetics on implants in maxillofacial surgical dentistry. In the future, these methods will be improved through the introduction of new materials, workflow optimization and improved design accuracy using CAD-CAM and 3D modeling technologies.
