Design features of a three-dimensional molar crown and related maximum principal stress. A finite element model study.

OBJECTIVE To evaluate the effects of clinically relevant variables on the maximum principal stress (MPS) in the veneer layer of an anatomically correct veneer-core-cement-tooth model. METHODS The average dimensions of a mandibular first molar crown were imported into CAD software; a tooth preparation was modeled by reducing the proximal walls by 1.5 mm… CONTINUE READING
