Can an increase in abutment screw length enable biomechanical advantages for implants with increased crown height space?

Abutment screw length and crown height affected the amount of stress generated on implant components. Increasing the screw length may reduce the stresses on the implant and bone without increasing the stresses in the screw, potentially mitigating the risk of implant platform fractures and bone resorption, both of which are critical failures. Screw related issues may decrease as the area stresses effect has a tendency to reduce when longer screw is used in increased CHS situation (tall crowns).

Abstract

Abutment screw length and crown height affected the amount of stress generated on implant components. Increasing the screw length may reduce the stresses on the implant and bone without increasing the stresses in the screw, potentially mitigating the risk of implant platform fractures and bone resorption, both of which are critical failures. Screw related issues may decrease as the area stresses effect has a tendency to reduce when longer screw is used in increased CHS situation (tall crowns).
