Resumen de Applications of fibreglass to reinforce the crown of endodontically-treated molars

Hipólito Fabra Campos, Manuel A. Radigales y Valls

• The crown reconstruction of an endodontically-treated molar allows different treatment options, from the classic crown of complete onlay cemented directly on the remaining crown closed with composite or on a cast post-core that restores the crown, to the simple reconstruction with composite. Between both options a wide range of treatment options are described, among which we can highlight the inlay with ceramic or prepolymerised resin overlay retainer. All admit the added insertion of the controversial screw or cemented post or even that which is adhered in the interior of one of the canals. It questions what is the best technique to use and how the decision made, which may always be disputed and even controversial, depends on the remaining crown that has been left in the endodontically-treated molar. Is that molar going to be capable of resisting the masticatory forces? Will the molar resist more if we restore its crown with composite to which we add a fibreglass reinforcement? We are going to show various techniques of crown reconstruction on endodontically-treated molars using Dentapreg® fibreglass.
