Resin cements: Composite luting cements

Abstract

Resin cements (composite luting cements) are used for cementation all ceramic crowns in contemporary dental practice. These materials which are characterized by type of fillers, initiation system, their viscosity, mechanical properties (wear resistance, elastic modulus, compressive strength, tensile and shear strength), and by their physical properties (CTE, radiopacity, polimerization shrinkage) became very popular in everyday practice. In that regard, this paper deals with some special characteristics of composite luting cements, as well as with the practical instructions during the cementation procedures connected to one of the commercial product of resin cements.

Savremena stomatološka praksa koristi za cementiranje keramičkih nadoknada kompozitne cementne materijale. Definisani različitim parametrima kao što su: odgovarajuća vrsta punioca, inicijatorni sistem, viskoznost, mehaničke karakteristike (modul elastičnosti, otpornost na habanje, čvrstoća na pritisak, istezanje i smicanje) i fizička svojstva (CTE, rendgenkontrasnost, polimerizaciona kontrakcija), strogo specifični za određene namene, ovi materijali zavređuju posebnu pažnju praktičara. Stoga, ovaj rad razmatra neke od njihovih specifičnosti sa osvrtom na pravila cementiranja i korektnu tehniku pri upotrebi jednog od poznatih preparata dvostrukopolimerizujućih kompozitnih cemenata.
