  • Patent number: 6981873
    Abstract: A dental implant includes a fixture and an abutment in a body, and a head for a compaction drill is configured for implanting such an implant. The implant includes an upper abutment portion on which a denture is fixed, a fixture portion implanted in the jawbone and forming single or double threads, and a settling portion formed between the abutment portion and the fixture portion. The invention improves the stability of the implant, improves stabilization of the bone tissue affixed to the implant, effectively seals the socket from its surroundings and facilitates bonding between implant and jawbone. This is achieved because of the early healing of tissue around the implant and the greater surface area in contact with surrounding tissue. As a result, an artificial crown may be coupled with the implant during the same surgery.
