Prosthetic crowns are made in accordance with the principles of clinical procedures while taking into account the rules of endurance, biocompatibility, and aesthetics. Depending on the biomaterial and manufacturing technology, crown frameworks are veneered with an appropriate set of ceramics with selected thermal expansion. The veneering layers responsible for tribological cooperation in occlusal contact should properly adhere to the framework. The aim of the research is to conduct the microscopic and EDS chemical analysis to evaluate the process of shaping veneering layers on frameworks produced using new digital technologies, i.e. the technology of milling and laser sintering. The research material consists of specimens produced in perpendicular cross-sections through the layered structures of metal-ceramic, ceramic-veneered glassceramic, and zirconium crowns. The microscopic examinations were carried out using the specimens and included the elemental EDS analysis performed on the surfaces and in certain points. The structures of metal and ceramic frameworks, ceramic veneering layers, and adhesive zones were determined.

Korony protetyczne wykonywane są zgodnie z procedurami klinicznymi oraz ze wskazaniami wytrzymałości, biozgodności i estetyki. Podbudowy koron, w zależności od zastosowanego biomateriału i technologii wytworzenia, poddawane są licowaniu odpowiednim zestawem ceramik o dobranej ekspansji termicznej. Warstwy licujące, odpowiedzialne za współpracę tribologiczną w kontakcie okluzyjnym, powinny charakteryzować się właściwą adhezją do podbudowy. Celem przeprowadzonych badań jest analiza mikroskopowa i chemiczna EDS pozwalająca ocenić proces kształtowania warstw licujących na podbudowach wytworzonych w nowych technologiach cyfrowych: w technologii frezowania oraz w technologii spiekania laserowego. Materiałem badań są zgłady wykonane w przekrojach prostopadłych przez warstwowe struktury koron: metalowo-ceramicznych, szklano-ceramicznych licowanych ceramiką i cyrkonowych licowanych ceramiką. Na zgładach przeprowadzono badania mikroskopowe z analizą pierwiastkową EDS na powierzchniach oraz w punktach. Identyfikowano struktury metalowych i ceramicznych podbudów oraz strukturę ceramicznych warstw licujących wraz ze strefami adhezyjnymi.
