Dental implant, and superstructure therefore
This invention pertains to a superstructure ( 300 ) for a dental implant. The superstructure comprises a fastening portion ( 30 ) with a joint socket in form of a spherically shaped cavity with a fastening surface ( 32 ), and a main portion ( 31 ). This superstructure ( 300 ) is intended to be joined to an osseointegrated dental implant via the fastening portion ( 30 ). The main portion ( 31 ) comprises a lead-through ( 110 ) for receiving a sleeve ( 111 ) or a screw hole ( 55 ), wherein part of said lead-through ( 110 ) or part of said screw hole ( 55 ) forms an opening in the fastening surface ( 32 ), such that there is a perpendicularly distance between the center of the spherical cavity and the central axis of the lead-through ( 110 ) or of the screw hole ( 55 ).
1. A superstructure for a dental implant, comprising:
a fastening portion including a joint socket in the form of a spherically shaped cavity with a fastening surface; and
a main portion;
wherein the superstructure is configured to be joined to an osseointegrated dental implant via the fastening portion;
wherein the main portion includes a hole for receiving a sleeve or a screw;
wherein part of the hole forms an opening in the fastening surface, such that a perpendicular distance exists between the center of the spherically shaped cavity and the central axis of the hole.
2. The superstructure according to claim 1 , wherein the central axis of the hole does not cut any part of the spherically shaped cavity.
3. The superstructure according to claim 1 , wherein the superstructure comprises:
a fastening part, suitable for fixating a ball socket of a dental implant, thus creating a ball joint; and
control means operably connected to the fastening part, the control means for activating the fastening part.
4. The superstructure according to claim 3 , wherein the control means comprises a screw member.
5. The superstructure according to claim 4 , wherein the thread of the screw member is left hand threaded.
6. The superstructure according to claim 1 , wherein the hole of the main portion is adapted to receive and fasten a separate sleeve.
7. The superstructure according to claim 6 , wherein the superstructure comprises a sleeve in the hole, the inside of the sleeve being threaded.
8. The superstructure according to claim 7 , wherein the sleeve is conical.
9. The superstructure according to claim 1 , wherein the hole of the main portion is a screw hole.
10. The superstructure according to claim 1 , wherein the hole of the main portion includes at least one protrusion.
11. The superstructure according to claim 1 , wherein a ball joint is fastened to the osseointegrated dental implant by one of the methods chosen from the group consisting of clamp, friction grip, screw anchoring, and a combination of screw anchoring and friction grip.
12. A dental implant system, comprising a dental implant and a superstructure joined with a ball joint, wherein the superstructure is according to claim 1 .
13. A dental implant system, comprising a dental implant adapter and a superstructure joined with a ball joint, wherein the superstructure is according to claim 1 .
