SET OF DENTAL COMPONENTS

摘要

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.

主权项

1. A set of male dental components, comprising
a first male dental component adapted to be connected to a mating first female dental component, the first male dental component comprising a threaded portion having a core provided with an external thread, and a second male dental component adapted to be connected to a mating second female dental component, the second male dental component comprising a threaded portion having a core provided with an external thread, wherein the core of the threaded portion of said first male dental component has a smaller diameter than the core of the threaded portion of said second male dental component, wherein, when finally tightened with the same torque to their respective mating female dental component, said first male dental component is configured and dimensioned to provide a higher friction against said first female dental component than the friction provided by the second male dental component against said second female dental component, and wherein each one of said male dental components has a contact surface for contacting its respective mating female dental component, wherein said contact surface of the first male dental component is different from said contact surface of the second male dental component, such that the coefficient of friction between said contact surface of the first male dental component and its mating first female dental component is higher than the coefficient of friction between said contact surface of the second male dental component and its mating second female dental component.
