There Are A Wide Variety Of Dental Abutments During The Evaluation Of Mechanical Properties (torsional Resistance, Tightening And Fatigue Resistance) Of A Product, How To Select The Investigational Typical Sample?

There are many types of dental abutments, including straight abutment, angled abutment, multi-unit abutment, ball abutment, bar abutment, locator abutment, and temporary abutment. For the dental abutment with the same connection mode within the same registration unit, it is allowed to select only the worst case for test according to the clinical scope of application. For example, for the permanent abutments for fixed restoration, the abutment with the largest angle and the smallest diameter may be selected and the ball abutment for overlay denture is tested separately. It is not necessary to test the mechanical properties (torsional resistance, tightening and fatigue resistance) of each type of abutment.
