Dental implant
View Patent ↗The subject matter of the disclosure is, in one example, a dental implant having a corpus, an external thread attached on the endosteal area of the corpus, and a post accommodation formed in the inside of the corpus. Providing a dental implant that can be anchored well in the jaw is achieved by forming a recess on the endosteal end of the corpus oriented coaxially to the longitudinal axis of the corpus.
1. A dental implant comprising:
a corpus having a longitudinal axis, a first end, a second end and an external surface having a first diameter and a conical cross-section at the second end;
a post accommodation at the first end, the post accommodation having a first internally threaded portion and a second portion;
a recess having at least a partially conical cross-section and a second diameter at the second end, wherein a width of the conical cross-section of the corpus decreases toward the second end and a width of the conical cross-section of the recess increases toward the second end, wherein the second diameter is substantially equal to the first diameter at the second end to form a tapered cutting edge based on the conical cross-section of the recess and the conical cross-section of the corpus, the cutting edge to cut through a bone;
a first set of openings intersecting the first internally threaded portion of the post accommodation; and
a second set of openings intersecting the second portion of the post accommodation, at least a portion of the first set of openings and at least a portion of the second set of openings to engage the bone when at least a portion of the corpus is disposed in the bone.
2. The dental implant of claim 1 , wherein the conical recess is to compress the bone.
3. The dental implant of claim 1 , further comprising a third set of openings in the corpus.
4. The dental implant of claim 1 , wherein the first set of openings extend transversely to the longitudinal axis.
5. The dental implant of claim 3 , wherein the third set of openings intersect at least one of the post accommodation or the recess.
6. The dental implant of claim 3 , wherein the third set of openings intersect at least one of the post accommodation or a channel extending coaxial to the longitudinal axis from at least one of the post accommodation or the recess.
7. The dental implant of claim 1 , wherein the first set of openings comprises a plurality of openings located at the external surface equidistantly from each other.
8. The dental implant of claim 1 , wherein the cutting edge comprises a tapered point at the second end.
9. The dental implant of claim 1 , wherein the post accommodation is formed inside the corpus.
10. A dental implant comprising:
a corpus having a longitudinal axis, a first end, a second end and an external surface having a first conical cross-section at the second end;
a post accommodation at the first end, the post accommodation having an internally threaded portion;
a recess having a first portion having a first diameter and a second portion having a second conical cross-section and a second diameter at the second end, the second diameter greater than the first diameter, wherein a width of the second conical cross-section increases toward the second end and a width of the first conical cross-section decreases toward the second end to form a tapered cutting edge;
a first opening intersecting the internally threaded portion of the post accommodation; and
a second opening intersecting the first portion of the recess, at least a portion of the first opening and at least a portion of the second opening to engage a bone when at least a portion of the corpus is disposed in the bone.
11. The dental implant of claim 10 , wherein the recess comprises an internal surface and at least a portion of the internal surface is angled at a first angle and at least a portion of the external surface is angled at a second angle such that the internal surface and the external surface meet at the second end.
12. The dental implant of claim 10 , where the post accommodation has a non-threaded portion adjacent the threaded portion and further including a second opening intersecting the non-threaded portion.
13. The dental implant of claim 10 , wherein the second opening has a third diameter, the first diameter greater than the third diameter.
14. A dental implant comprising:
a corpus having a conical cross-section at an endosteal end of the corpus;
an external thread attached to an endosteal area of the corpus;
a post accommodation formed inside the corpus, the post accommodation having an internally threaded portion;
a recess formed on the endosteal end of the corpus coaxial with a longitudinal axis of the corpus, the recess at least partially conically tapered and having a first diameter at the endosteal end of the corpus, wherein a width of the conical cross-section of the corpus decreases toward the endosteal end and a width of the conical cross-section of the recess increases toward the endosteal end to form a tapered circumferential cutting edge adjacent to the recess at the endosteal end of the corpus;
a channel extending coaxial to the longitudinal axis of the corpus from at least one of the post accommodation or the recess, the channel having a second diameter, the first diameter greater than the second diameter; and
a first opening intersecting the internally threaded portion of the post accommodation, at least a portion of the opening to engage a bone when at least a portion of the corpus is disposed in the bone.
15. The dental implant of claim 14 , wherein the first opening is formed radially to the longitudinal axis of the corpus.
16. The dental implant of claim 15 , wherein the first opening is at least partially a hollow cylinder.
17. The dental implant of claim 16 , wherein the first opening has an inner diameter of not more than about 1 mm.
18. The dental implant of claim 14 , further comprising a second opening coupled to the recess.
19. The dental implant of claim 14 , further comprising a second opening coupled to the post accommodation.
20. The dental implant of claim 14 , further comprising a second opening, wherein the first opening and the second opening are transverse to the longitudinal axis of the corpus.
21. The dental implant of claim 20 , wherein the first opening and the second opening are equidistant to the longitudinal axis of the corpus.
22. The dental implant of claim 21 , wherein the circumferential cutting edge comprises a pointed edge at the endosteal end of the corpus, the pointed edge to cut bone.
