[Results of the use of whole ceramic prosthetic constructions from zirconium oxide for recovery of the teeth with deep subgingival defects].

30 patients (13 men and 17 women) with deep subgingival defects were selected for treatment, their mean age was equal to 39.7+/-3.2 years; for their teeth recovery 38 stump inlays from zirconium oxide were made. The patients were distributed in 3 groups depending upon the material used for inlay fixation; for 2 years in the dynamic regime (after 6, 12 and 24 months) clinical evaluations were done of the quality of tooth recovery. Medium-term results of the quality of tooth recovery clinical evaluations by inlays from zirconium oxide have shown that this method is perspective for teeth recovery with deep subgingival defects. Such qualities of metal-free ceramics as practicality, biocompatibility, stability and excellent aesthetic characteristics have provided high quality of the treatment. At the same time stability and longevity of the prosthetic constructions were formed not only by mechanic characteristics of the used materials but also by such fixating cements properties as the degree of edge protection and resorption resistance. Adhesive inlay fixation with the use of such cements as Panavia F and Fuji plus have demonstrated stabile joint with perfect edge conformity.
