Abstract: Oral implants for original entry and re-entry procedures have implant portions that are positioned in grooves in the bone such that they are submergible below the upper rim of the bone. A post assembly for immediate installation of an artificial tooth structure may be detachably corrected to the implant portion. Alternatively, a cap may be attached and covered by tissue. Once the bone has grown over the implant portion, except in the area of the cap, the tissue is reopened and the cap is replaced by the post. In narrow bone areas the implant portion is a blade with a snap-on cap. In broad bone areas, the implant portion is box shaped and has a screw on post. If desired, the artificial tooth structure may be detachably connected to the post assembly for easy removal.

Abstract: An oral implant for supporting an artificial tooth structure includes an implant portion which is buried in the bone of the patient along the occlusal plane. A neck portion extends from the side of the implant portion remote from the groove and receives a post portion on which the artificial tooth structure is cemented. Means are provided on the neck portion so as to cause it to become wedged within a cavity of the overlying post portion, thereby releasably locking the post to the neck portion. As a result of this arrangement, a bridge structure can be removed from an implant without having to destroy the bridge.

Abstract: An oral implant allows for the immediate installation of an artificial tooth support structure in a jawbone portion which has become oversized due to a failed prior blade implant or an enlarged tooth socket. The implant includes one or more posts upon which the artificial tooth is mounted, as well as a support structure whose lateral dimensions is sufficient to permit it to be wedged in the oversized opening. Preferably, the lateral dimension is adjustable to various size openings in the jawbone.

Abstract: An oral implant for permanently implanting an artificial tooth supporting structure in a jawbone is adapted for use at a location where the jawbone is insufficient to support an implant blade. This implant includes a remote blade which is positioned into the jawbone at a location remote from the position where the artificial tooth is to be fixed and at a position where there is sufficient bone structure to support it. At least one post is positioned at the location where the artificial tooth is to be mounted. A cross-connecting structure connects the post and the remote blade.

Abstract: 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 first telescoping part 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 laterally aligned first and second portions, the first portion being adapted to engage and be secured to an associated symphysis blade post and the second portion defining a second telescoping part adapted to telescopically cooperate with an associated ramus blade second portion.

Abstract: 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.

Abstract: 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.
