Set of dental components

Abstract

According to an aspect of the invention, in a set of male dental components, such as abutment screws, each male dental component has a threaded portion with different core diameter. Each male dental component is to be connected to a mating female dental component, such as an abutment. The smaller core diameter a threaded portion has, the higher friction is provided when the male dental component is finally tightened to its mating female dental component, even though the same insertion torque is applied to all male dental components.
