DENTAL IMPLANTATION IN PROSTHETICS OF PATIENTS AFTER OSTEORECONSTRUCTIVE PLASTY

The results of long-term clinical observations on the prosthetics of denture defects using dental implants in patients after osteoplastic surgeries performed for inflammatory diseases, traumatic lesions, tumors and tumor-like formations of the maxillofacial region in 246 patients are presented. Free-end edentulous spaces were identified in 174 patients, bounded edentulous spaces – in 72. Two types of dental implants were used: porous titanium nickelide and screw. In 99 patients, dental implants were transplanted together with a bone allo- or autograft during bone grafting of a jaw defect, in 60 patients – in bone regenerate in the long term after bone grafting and replacement of the defect with a neoformed bone, in 87 patients – in sinus lifting. During orthopedic treatment, 359 fixed prostheses and 18 removable structures based on dental implants were made. The results of ostseointegration of dental implants were evaluated by comparative osteodensiometry within 1.5 to 12 months. Clinical observations and osteodensiometry have shown that the integration process evolves more fully and effectively around titanium nickelide implants with permeable porosity. The most common complication of dental implantation in bone regenerate is peri-implantitis, which developed in 30 patients (5.18%). Positive aesthetic and functional long-term results of denture defects prosthetics defects on implants in terms of up to 12 years were observed in 90.8% of cases
