Differences between adhesive protocols in lithose disilicate restorations and zirconium restorations

Abstract

Background: In restorative dentistry there are different materials available when deciding the ideal prosthetic treatment for the patient, which means that it becomes necessary to have substantial knowledge of the protocols and techniques indicated at the time of rehabilitation. Each material has a particular composition and properties, as well as, it is necessary to take into account the surface to which it must adhere; all this requires a different protocol. Purpose: the objective of the present study was specifying the differences between the adhesive protocols in permanent ceramic restorations of lithium disilicate and zirconium restorations. Materials and Methods: This research focused on conducting a systematic review, and the search was carried out through the search engines PubMed, Scielo, ResearchGate, ScienceDirect and Google Scholar. Results: A total of 15 articles were obtained that met the inclusion and exclusion criteria. Conclusions:  it is concluded that, in the case of zirconium, microsanding with aluminium particles and self-adhesive cement is often the one of choice. On the other hand, in the case of lithium disilicate, etching with hydrofluoric acid and self-adhesive cement is the most suitable. Finally, it is important to recognize that, in the case of not using an adhesion protocol, there is the possibility that the necessary quality controls are not met, making the restoration a failure, being able to fractured or damaged. anyway.
