INFLUENCE OF THE ANGLE OF CERVICAL CONVERGENCE ON STRESSES TO THE PDL OF ABUTMENTS: A 3D ANALYSIS USING FINITE ELEMENT METHOD

Influence of the Angle of Cervical Convergence on Stresses to the PDL of Abutments: A 3D Analysis Using Finite Element Method

Objective: This study was designed to compare the stress produced at the PDL of abutment teeth with two angles of cervical convergence, in otherwise similar settings.Materials and Methods: Two finite element models were designed for a second premolar Exteriors and a removable partial denture frame containing an I-bar clasp.Maximum Principal Stress

Effect of austempering conditions on the microstructure and mechanical properties of AISI 4340 and AISI 4140 steels

AISI 4340 and AISI 4140 are normally used for different structural applications in quenched and tempered state due to their high strength, high abrasion and fatigue resistance but they lack toughness.Presence of dual phase microstructure Covers such as ferrite-bainite and ferrite-martensite in steels have been reported to improve toughness but at t
