Behavior of peri-implant tissue in the presence of zirconium as a subgingival material.

Abstract

Background: For many years (Zr) has proven to be a biocompatible material with great resistance to corrosion and a very low level of toxicity. On the other hand, studies confirm that it presents adequate adhesion of peri-implant soft tissues compared to other subgingival restorative materials.  Purpose: The objective of the present study is to know the behavior of peri-implant tissue in the presence of zirconium as a subgingival restorative material. Results: 46 articles were identified through the search, of which 24 were excluded for not presenting relevant information on the behavior of peri-implant tissue before zirconium as a subgingival material, 3 excluded for being duplicates. 15 articles were evaluated, of which 4 were discarded for different reasons. 11 articles were included for discussion in that systematic review. Conclusions: It is concluded that (Zr) has proven to be the main subgingival restorative material of choice in dentistry due to its biocompatible properties in relation to its hardness, aesthetics and response of the peri-implant tissue. Its benefit lies in its hydrophilic quality and low surface energy, which provide a better response from gingival fibroblasts and favors the early formation of mucosal seals.
