Optimal cosmetic solution for prosthetic restorations.
Single ceramic restorations incorporating glass-fiber posts in the laboratory.
Direct restorations with glass-fiber post.
Elasticity modulus similar to dentine.
Favourable constraint: deformation ratio for the tooth. Homogenous distribution of mechanical constraints.
“In fact teeth restored using glass-fiber posts result in only a small number of failures, which are often repairable. In contrast, teeth restored using metal posts commonly present with more significant fractures, often resulting in the loss of the tooth.“ (Standlee, 1988; Freeman, 1998).
Chemical retention between the core build-up and the glass-fiber post (mechanical retention only in a steel post procedure).
