In everyday dentistry practice cases with diffuse destruction of masticatory teeth are common. In the study presented the possibilities of their restoration with metal or metal-ceramic inlays are reviewed. Twenty-one inlays were fabricated, 16 from metal and 5 from metal-ceramic. The quality of the fabricated obturations were assessed immediately after they were cemented and one year later. The results showed that this is a reliable method. During the studied period there were no changes in the inlays, the teeth tissues and marginal adaptation.
