Selección de métodos de cementación para prótesis dentales fijas (coronas o puentes), encuesta entre odontólogos en Ecuador.

Abstract

Introduction: Among the materials most commonly used by Dentists for the fabrication of Fixed Dental Prosthesis (PDF) of crowns and bridges are alloys and porcelain fused to metal (PFM), feldspar glass ceramics reinforced with leucite, lithium disilicate glass ceramics and polycrystalline ceramics, zirconium ceramics reinforced with lithium silicate and CAD/CAM resin composites. The aim of this study is to determine the cementation methods preferred by dentists for fixed dental prostheses (crowns or bridges) in Ecuador. Materials and methods: A qualitative-quantitative, cross-sectional, descriptive and analytical study with a deductive-inductive method. The questionnaire was completed by 441 Ecuadorian dentists, of whom 144 met the inclusion criteria. Results: The use of adhesive luting predominated when dentists used leucite-reinforced feldspar glass-ceramics (47.9%), lithium disilicate (52.1%), zirconia-reinforced lithium silicate (43.1%), polycrystalline ceramics (39.6%) and CAD/CAM resin composite restorations (46.5%). For metal-ceramic alloys/ restorations, the use of conventional cement predominates (51.4%). Conclusion: In this study, the results suggest the partial rejection of the hypothesis, due to the fact, that for Ecuadorian dentists, the economic factor plays a determining role when deciding which dental cement to buy.
