Fracture Resistance and Push-Out Bond Strength of Three Post Types in the Restoration of Anterior Primary Teeth - A In Vitro study.

Context: Restoration fractures and displacement are the two main causes of failure after the rehabilitation of severely worn primary anterior teeth.

Aims: Compare the effect of three post types on the fracture and push-out bond strength.

Methods And Materials: Sixty undamaged maxillary anterior primary teeth were allocated into three groups according to post type: (I) Tetric N Ceram composite post, (II) prefabricated glass fiber post, and (III) high viscous glass ionomer post.
