All Myriad™ abutment screws feature the innovative Graphyte™ low friction coating that delivers optimal pre-loads at minimum torque levels. Titanium inherently is a high friction material as compared to stainless steel or gold. High friction between two titanium components can be compensated by the application of higher torque, but higher torque in an abutment screw assembly can increase torsion stress in the screw stem which is not ideal.
Higher gripping force for Graphyte™ low friction coated screws at lower tightening torque values as compared to standard titanium screws.
The Graphyte™ low friction coating on all Myriad™ abutment screws reduce friction to deliver a higher gripping force at lower tightening torque values.
