In Vitro Study the Differential Thickness Strength of Porcelain Laminate Veneers to Fracture Forces

Porcelain is used in thin thicknesses to fabricate ceramic veneers. The low fusing feldspathic porcelain used to fabricate porcelain veneers is easily fractured, brittle porcelain before cementation to tooth structure. However, its fracture resistance improves significantly after etching with hydrochloric acid, applying the silane and luting to tooth structure with resin cement. Aim of the study: to evaluate the appropriate thickness of laminates made from feldspathic porcelain and its relation to flexural strength.
