[Experimental studies of the proper indication of inlay and crown therapy in lateral tooth areas].

In the framework of a study involving both experimental and clinical tests, two preliminary tests were made to measure and compare the edge lengths of crowns and inlays and the substance losses after tangential and circular stage-type preparations. As revealed by the results, both the three-face and two-face cast fillings in the lateral tooth area have a longer restoration edge than corresponding cast crowns. The weight loss after crown preparations involving a circular stage is greater by one third than after a tangential preparation. In this context, ways of properly using restorative means of therapy in clinical dentistry are discussed.
