Restoring endodontically treated teeth with all-ceramic endo-crowns: Case report

Abstract

The all-ceramic endocrowns are one piece restoration used in the therapy of endodontically treated teeth, usually, with a decreased vertical dimension of the tooth crown. The aim of this paper is to describe two techniques of the making of endocrowns using case studies and to present the advantages and disadvantages of both techniques by way of their comparison. Chair-side production with the Cerec CAD-CAM system and pressing of the ceramic with the Empres II system was used for the production of the endocrowns. Cerec CAD-CAM and Empres II systems yielded equally good results in the production of the endocrowns, in terms of their functionality, retention, aesthetic and duration. The basic difference between them is the length of the endocrown production procedure as the Cerec CAD-CAM system makes it possible to apply the treatment during a single visit using a wide range of materials….

Bezmetalne endokrune su jednokomadne nadoknade koje se koriste u terapiji endodontski lečenih zuba u uslovima smanjene vertikalne dimenzije krunice zuba. Cilj ovog rada je bio da se na slučajevima iz kliničke prakse predstave dve tehnike izrade endokruna i da se poređenjem karakteristika tih sistema ukaže na njihove prednosti i nedostatke. Kod jednog pacijenta, za izradu endokruna korišćena je jednoseansna izrada Cerec CAD-CAM sistemom, a kod drugog presovanje keramike Empres II sistemom. Obe tehnike, i Cerec CAD - CAM i Empress II sistem, pokazale su podjednako dobre rezultate, u smislu funkcionalnosti, retencije, estetike i dugotrajnosti endokruna. Osnovna razlika je u trajanju procedure izrade endokruna jer Cerec CAD - CAM sistem omogućava tretman u samo jednoj poseti pacijenta i koristi širu paletu gradivnih materijala.
