Both ceramics and metal are widely used as a material of choice for dental tissue restoration. However, metal-free ones provide higher aesthetic and adaptive performance. In addition, it was studied out that last years have comprehended a dramatic upsurge in the patients' non-metallic materials demand, occasionally induced by metal-phobia or alleged allergies. The research aims to improve the effectiveness of treatment of patients with defects using ceramic restorations in hard dental tissues. We have treated 60 patients using metal-free restorations made by pressing and milling (2 groups both with 30 patients). For results analysis we used several criteria (accuracy of fit of the restoration, color matching, probability of a cement connection loss, the presence of chips of the restoration in the oral cavity) and counted statistics probability of groups comparisons. We discovered several advantages of milled restorations in adhesion to dental tissues and color matching. Hence, it is highly recommended to use metal-free constructions for the prosthetic restoration of hard tooth tissues.
