Fig. 2From: An in vitro study evaluating the effect of ferrule design on the fracture resistance of endodontically treated mandibular premolars after simulated crown lengthening or forced eruption methodsPreparation designs. F0: with 0.0 mm buccal and 2.0 mm lingual ferrule lengths, as control; CL/F1: with simulated crown lengthening and 1.0 mm buccal and 3.0 mm lingual ferrule lengths; CL/F2: with simulated crown lengthening and 2.0 mm buccal and 4.0 mm lingual ferrule lengths; OE/F1: with simulated orthodontic forced tooth eruption and 1.0 mm buccal and 3.0 mm lingual ferrule lengths; OE/F2: with simulated orthodontic forced tooth eruption and 2.0 mm buccal and 4.0 mm lingual ferrule lengthsBack to article page
