Indications for the use of endocrowns, design and selection of materials: Literature review

Abstract

Introduction: Endocrowns are a valuable rehabilitation option in dental pieces that have suffered extensive tissue loss, being retained to the internal portion of the pulp chamber through the use of adhesive cementation Objective: To carry out a review of the literature on the criteria endocrown use, preparation designs for this type of restoration and the selection of materials for this restoration. Methodology: A review was carried out in the Scopus, Pubmed and Scielo databases with the keywords "endocrown", "design", "fit", "materials", "restoration" Results: Within the best studied design criteria are at least 2 mm of occlusal reduction and extension towards the pulp chamber, elements such as a 1 mm splint and stabilization notches seem to improve performance. Lithium disilicate is the most widely used material, but hybrid ceramic and composite CADCAM blocks are promising. Materials such as zirconia or metal increase the risk of irreparable fracture. Conclusion:Knowing the design criteria supported by evidence, as well as an adequate selection of materials, makes the endocrown a valuable restorative option.

Comparative analysis of endocrown fracture resistance and marginal adaptation: CAD/CAM technology using lithium disilicate vs. zirconia-reinforced lithium silicate ceramics

“…Lithium disilicate is a widely utilized and extensively researched material for producing endocrowns. One of its primary benefits is its exceptional blend of aesthetic appeal and mechanical strength ( Zardoni et al, 2023 ). However, studies comparing the marginal adaptation of LDS and zirconia-reinforced lithium silicate (ZLS) endocrowns are limited, and the available ones have reported contradictory results ( Ji et al, 2015 , Taha et al, 2018 ).…”
