Abstract
A dental implant includes an anchoring region (12) for anchoring in a bone, which preferably includes a thread (14) for screwing in the bone, and a fastening region (22) for attaching a supra-construction, wherein an abutment region (16) adjoins the anchoring region (12), the abutment region (16) having a guide structure with a plurality of outwardly projecting ridges (18) provided thereon, and preferably, grooves (20) being formed between the ridges (20). The guide structure of the anchoring region (12) allows a better osseointegration and counteracts peri-implant bone loss.
Claims20
A dental implant comprising:
- an anchoring region for anchoring into a bone, the anchoring region having a thread for screwing into a bone;
- a fastening region for fastening a supra-construction;
- and
- an abutment region adjoining the anchoring region and forming a top surface of the dental implant, the abutment region having a guide structure with a plurality of outwardly projecting ridges provided on its outer surface and a groove formed between respective ones of the plurality of ridges,
- wherein the plurality of ridges include at least three ridges,
- wherein the abutment region has a top and a bottom and the grooves formed between the plurality of ridges extend from the top to the bottom of the abutment region, and
- wherein the plurality of ridges do not form a thread.
A method of implanting a dental implant, the method comprising:
- forming a recess in the bone, the recess being adapted to receive the anchoring region and being formed by drilling, ultrasonic cutting or laser cutting;
- and
- anchoring the implant in the recess in a manner that the abutment region aligns approximately with the bone level, or projects over the bone level by a small amount, the amount being a maximum of 0.5 millimeter to 2 millimeters, the dental implant comprising
- an anchoring region for anchoring into a bone, the anchoring region having a thread for screwing into a bone;
- a fastening region for fastening a supra-construction;
- and
- an abutment region adjoining the anchoring region and forming a top surface of the dental implant, the abutment region having a guide structure with a plurality of outwardly projecting ridges provided on its outer surface and a groove formed between respective ones of the plurality of ridges,
- wherein the plurality of ridges include at least three ridges,
- wherein the abutment region has a top and bottom and the grooves formed between the plurality of ridges extend from the top to the bottom of the abutment region, and
- wherein the plurality of ridges do not form a thread.

- wherein the abutment region has a top and bottom and the grooves formed between the plurality of ridges extend from the top to the bottom of the abutment region, and
- wherein in a planar development of the abutment region the ridges have a convex shape from the anchoring region towards the end of the abutment region located distal to the anchoring region, and
- wherein the plurality of ridges do not form a thread.
