US Patent:

47130040, Dec 15, 1987

Filed:

Sep 4, 1986

Appl. No.:

6/904381

Inventors:

Leonard I. Linkow - New York NY
Anthony W. Rinaldi - Philadelphia PA

Assignee:

Vent Plant Corporation - Philadelphia PA

International Classification:

A61C 1300

US Classification:

433174

Abstract:

A submergible screw-type implant includes a longitudinal channel which directs bone chips towards the base of a bore in the patient's bone in which the implant is installed. These bone chips promote autogenous rapid regrowth of new bone to securely anchor the implant in place. In order to be able to position the implant at the most advantageous angle at the edentulous site, angled abutments for supporting an artificial tooth structure or angularly adjustable abutments are provided. A method of installing the angularly adjustable oral implant involves setting the abutment portion at the proper angle for alignment of the artificial tooth and subsequently locking it in that position.

Assignee:

Vent-Plant Corporation, Inc. - Philadelphia PA

International Classification:

A61C 800

US Classification:

433173

Abstract:

An implant portion of an oral implant arrangement for supporting an artificial tooth structure has an elongated body having a first and a second ends. The first end is adapted to receive at least a portion of the artificial tooth structure. The second end is adapted for insertion into a crypt in a bone located to support the artificial tooth in the vicinity of the occlusal plane of a patient. At least one longitudinal column projecting outwardly from the outside surface of the elongated body and extending at least part way toward the second end of the body is provided. A cutting arrangement is defined at the end of the longitudinal column toward the second end of the body. During insertion of said elongated body into the crypt in the bone the longitudinal column closely engages slots formed within the walls of the bone crypt by the cutting arrangement so as to create at least one antirotational pillar which resist accidental spinning of the implant portion in the crypt.

C23C 1446

US Classification:

623 16

Abstract:

A process is provided for depositing hydroxylapatite on the surface of materials suitable for implantations into animals and humans. In this process, a coating of hydroxylapatite is applied to dental or surgical implants using a sputter technique that employs a high energy Xenon ion beam. The process is carried out in a vacuum into which a controlled amount of hydroxide ions are introduced.

Abstract:

A process is provided for depositing hydroxylapatite on the surface of materials suitable for implantation into animals and humans. In this process, a coating of hydroxylapatite is applied to dental or surgical implants using a sputter technique that employs a high energy ion beam and a negative potential to coat the implant. The process is carried out in a vacuum into which a controlled amount of oxygen is introduced.

Assignee:

Vent-Plant Corporation - Philadelphia PA

International Classification:

A61C 800

US Classification:

433174

Abstract:

A submerigible screw-type implant includes a longitudinal channel which directs bone chips towards the base of a bore in the patient's bone in which the implant is installed. These bone chips promote autogenous rapid regrowth of new bone to securely anchor the implant in place. In order to be able to position the implant at the most advantageous angle at the edentulous sight, angled abutments for supporting an artificial tooth structure or angularly adjustable abutments are provided. The angularly adjustable abutments may be in the form of a ball and socket joint in which the socket includes an inner casing having a peripheral extension that acts to lock the joint at the desired angle. Also, the support for an artificial tooth may include a shock-absorbing cushion to prevent some of the forces of mastication from disturbing the implant.

International Classification:

A61C 302

US Classification:

433165

Abstract:

A drill for forming a hole in material has a shank with at least a base surface positioned at an angle to a longitudinal axis of the shank and a side surface. A cutting element having first and second ends is eccentrically connected to the base surface in such a manner that a longitudinal axis of the cutting element is situated at a predetermined distance from a longitudinal axis of the shank. An outer surface of the body of the cutting element is defined by at least a front surface and a rear surface intersecting each other along at least a cutting edge. The rear surface is tapered toward the longitudinal axis of the shank so that only the cutting edge and the drill point engage the material and a substantial open area exists between the outer surface of the cutting element and the hole during the entire process of drilling.
