[The characteristics of the design and use of metal-ceramic dentures in pathological abrasion of the hard dental tissues].

A total of 416 patients aged 40 to 60 suffering from abnormal teeth abrasion were fitted with cermet dentures. Orthodontic treatment was preceded by therapeutic and surgical preparation of the teeth and periodontium and by functional and adaptation rearrangement of the maxillodental system, if indicated. Remote results were assessed after 2 to 12 years. Due to such preparation good results were attained in 95.9% patients. Complications were observed in only 4.1%: exacerbation of periodontitis, ceramic facing chipping off, insertion of abutment teeth, and functional overload of the periodontium.
