The boundary conditions were defined by fixing both lateral exterior surfaces of the bone segment. A load of 49 N was applied in the palatal region of the prosthetic crown angulated at 45° with the ...

A torque load of 25 Ncm was applied to the regular and short implant screw. Von Mises stress distributions of implants, abutments and crowns were evaluated by using FEA. Increased angle in implants ...

Abstract. Aim: To investigate the effect of implant-abutment angulation and crown material on stress distribution of central incisors.Finite element method was used to simulate the clinical situation ...

For hard roof circumstances, the influence range of front abutment stress reaches 97 m, the peak stress increases to 55.4 MPa, and the stress concentration factor gets to 3.85. In the other condition, ...

To that end, they recruited 102 front-line workers from three COVID units in hospital settings. Each wore a VR headset and watched a three-minute video of a lush green nature setting.
