Protocolo de cementación para coronas de disilicato de litio vs zirconio. Revisión sistemática.

Abstract

INTRODUCTION: Aesthetic dentistry has been continuously revolutionizing and has contributed to more effective treatments, among the materials that have stood out today are lithium disilicate and zirconium, considered highly aesthetic, used in rehabilitating structures. OBJECTIVE: To determine the cementation protocols in lithium disilicate vs zirconium crowns. MATERIALS AND METHODS: A systematic, crosssectional and retrospective review study was conducted, with a descriptive and analytical design; through a review of the literature in different meta-search engines such as Pubmed, Science Direct, Google Academic, Scielo and the virtual library of the UCSG, of which 30 articles were selected as a sample ranging from 15 years old to the present. RESULTS: Disagreement was found in the cementation protocols between lithium and zirconium disilicate; Regarding dental preparation, disilicate crowns were all conservative, anatomical preparation predominated in zirconium crowns, lithium disilicate crowns were more worn and zirconium crowns were less worn. CONCLUSION: The zirconium cementation protocol is similar to that of lithium disilicate, with the difference of aluminum sandblasting and the use of silane that is used during lithium disilicate cementation. KEY WORDS: Lithium zirconium disilicate, cementation, cementation protocols, fixed prostheses, dental crowns, zirconium cementation protocol, lithium disilicate cementation protocol.
