Effect of Ferrule Location with Varying Heights on Fracture Resistance and Failure Mode of Restored Endodontically Treated Maxillary Incisors.
Domingo Santos PantaleónFabio M ValenzuelaBrian R MorrowCornelis H PameijerFranklin García-GodoyPublished in: Journal of prosthodontics : official journal of the American College of Prosthodontists (2019)
Specimens with a complete ferrule of 2 mm height were more resistant to fracture than specimens with 2 mm height and absence of the lingual wall and 1 proximal wall. A 3 or 4 mm wall height increase was associated with an insignificant increase in fracture resistance and cannot compensate for the absence of the lingual wall and 1 proximal wall.
