METHOD FOR MAKING RELEASING POSTOPERATIVE MAXILLOFACIAL PROSTHESIS Russian patent published in 2014 - IPC A61C13/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to dentistry, and is applicable in making a releasing postoperative maxillofacial prosthesis for all types of maxillectomy. A patient's oral cavity is optically imprinted. An optical imprint is digitised by means of a computer unit of CAD/CAM system. Planned surgical area boundaries are modelled on the formed image, and the above boundaries are virtually engraved vertically and horizontally at a width and a depth of 2.5 mm. A base of the releasing postoperative maxillofacial prosthesis is modelled with retention elements, and scanned patient's dental arch images are attached by matching technique. The modelled construction of the releasing postoperative maxillofacial prosthesis with artificial plastic-plate teeth is milled. The made prosthesis is processed, ground and polished. The prosthesis is fixed in the patient's oral cavity.

EFFECT: by providing a one-piece configuration of the releasing postoperative maxillofacial prosthesis with the retention elements by computed milling, the method enables recovering the masticatory function, ensuring the prosthetic bed formation within the surgical area and the optimum fixation in the unfavourable clinical environment of the prosthetic bed.
