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.

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.

A symphyseal-rami endosteal implant comprises a symphysis blade, at least one ramus blade, and at least one intermediate member. The symphysis blade has a first portion adapted to be received in the symphysis bone and a second portion defining at least one projecting post. The ramus blade has a first portion adapted to be received in a ramus bone and a second portion defining a rod adapted to extend generally parallel to the occlusal plane when the ramus blade first portion is received in the ramus bone. The intermediate member has generally vertically aligned first and second portions, the first portion being adapted to engage, slide longitudinally with respect to, and be secured to a length of the rod and the second portion being adapted to engage and be secured to an associated symphysis blade post.

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.

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.

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.

A wide vent dental implant adapted to be driven into the jaw bone of an individual and having a wide flat blade portion offering a large surface area for frictional retention in the jaw bone, and a head portion which remains exposed outside the jaw and provides a support for dental appliances of various types requiring an anchorage to the jaw bone. The bottom edge of the blade portion is sharpened to provide a cutting edge which incises the jaw bone as the wide vent is driven into place.
