The Effect of Ferrule Design On Fracture Resistance and Failure Modes of Indirect Composite Endocrowns

Prosthetic restoration of endodontically treated teeth with severe loss of coronal structure is often a clinical challenge [1], related to their higher rate of biomechanical complications when compared to vital teeth [2, 3]. They have been traditionally restored with post and coresand full crowns.[4] Despite of the clinical success usingintraradicular posts, one disadvantage of using this technique is the additional reduction of sound tissue.
