Abstract
A dental implant system that can include a prosthetic assembly and a dental implant. The prosthetic assembly can include a dental component and a retention screw. The dental component and the retention screw each have interference elements that are configured to engage when a removal torque is applied to the screw. When the interference element engage each other, a portion of the removal torque is converted into a linear force that is exerted on the dental component in a removal direction thereby separating the dental component from the dental implant.
Claims20
A dental implant system, comprising:
- a prosthetic assembly including:
- a dental component comprising:
- a bore extending from a distal end to a proximal end, the bore comprising an interference portion;
- an implant engagement section at the distal end and comprising a first anti-rotation portion extending distally from the implant engagement section;
- and
- a post section at the proximal end and comprising a second anti-rotation portion extending longitudinally from the proximal end of the post section towards the implant engagement section and configured to interlockingly engage a bore of a mating component, wherein the second anti-rotation portion comprises a projection configured to engage a groove in the mating component or a plurality of grooves configured to engage a plurality of projections in the mating component, the plurality of grooves extending circumferentially around the post section;
- and
- a retention screw configured to extend through the bore of the dental component, the retention screw including:
- a head;
- a shaft extending from the head;
- an apical threaded portion positioned at a distal end of the retention screw;
- and
- a coronal engagement portion positioned between the apical threaded portion and a proximal end of the retention screw,
- wherein the engagement portion is configured to engage the interference portion of the dental component when a removal torque is applied to the retention screw to remove the retention screw from an implant.

- and
- a retention screw (18, 92) configured to extend through the bore of the dental component, the retention screw including:
- a head;
- a shaft extending from the head;
- an apical threaded portion positioned at a distal end of the retention screw;
- and
- a coronal threaded engagement portion positioned between the apical threaded portion and a proximal end of the retention screw,
- wherein the threaded engagement portion is configured to engage the threaded interference portion of the dental component when a removal torque is applied to the retention screw to remove the retention screw from an implant.
