Abstract:
An endosseous jaw implant for insertion into a cavity formed in a jaw bone has a central implant body onto which at least one anchor wing is integrally molded. The anchor wing has a wedge-shaped cross section, and at least a front edge and/or a back face or an axis of the center of gravity of the anchor wing extends secantally away from the implant body.
Abstract:
A dental implant assembly 10 for implanting an artificial tooth into the mouth of a patient. The dental implant assembly 10 has a lower component 12 including a foot 16, a core 18, a shoulder 22 and a neck portion 20. The lower component 12 is seatable in an upper component 14 that is detachably attachable to the lower component 12. A barrel-shaped body 36, 38 is included in the upper component 14. It has major 36 and minor 38 members that are juxtaposed and adapted to secure a prosthesis 34.
Abstract:
A dental implant assembly kit and method for insertion into a bone, the assembly serving to support a dental prosthesis or other dental structure. The assembly includes a base plate having a bone-facing surface and a pillar-supporting surface that defines an off-center region; a ledge depending from the bone-facing surface of the basal plate; and a pillar extending from the off-center region of the pillar-supporting surface of the basal plate.
Abstract:
A dental implant is a submerged endosseous implant system and a blade implant is an integral one-piece body member having a blade-like portion, a collar support portion, and one or more cylindrical tubular collars, with each cylindrical collar having an internal screw-threaded bore. After the blade body member is positioned in the groove in the patient's jaw a short flat healing plug is screwed into the collar bore and the gum sutured and allowed to heal. After healing, the flat-headed plug is removed and an abutment head is screwed into the collar bore, the head including an externally threaded shaft portion and a head portion having a groove. The top head portion may be bent at the groove to obtain the desired head angle. The same type of abutment head is used with a submerged screw implant.
Abstract:
An endosseous implant is disclosed for permanent implantation within a groove formed in the posterior alveolar process in the mandible of the mouth of a patient. The implant comprises a supporting head for supporting a crown portion of an artificial tooth. The supporting head has a substantially horizontal top surface and a base portion. A constricted neck portion is rigidly secured to the base portion for supporting the supporting head. An apertured blade portion is also rigidly secured to the neck portion such that the neck portion connects together the supporting head and the blade portion. The blade portion includes a lingual and a buccal face and a mesial and a distal portion. The mesial portion of the blade portion has a blunt mesial edge and the distal portion has a distal edge of pointed configuration. The neck portion is disposed adjacent the juncture of the mesial and the distal portions and the distal portion is curved away from the longitudinal axis of the mesial portion. In use of the implant, the distal edge is inserted within a groove formed in the alveolar process and the blunt mesial edge is gently hammered so that the distal edge penetrates into the alveolar process towards the Ramus. In an alternative embodiment of the invention, the distal edge is a shallower version of the mesial portion.
Abstract:
This invention relates to a prosthetic dental tooth implant for anchoring a tooth to the jaw bone of an individual. The device is a blade like section having a number of circular holes having a slot-like aperture in a bottom portion of the blade to provide flexure of the blade and outwardly bendable prong extending from a top portion of each hole for anchoring engagement against an inner surface of the cortical plates adjacent the aveolar tissue of the jaw bone.
Abstract:
A suitable dental implant which I term a submerged dental implant and which may be of either the post or blade type, but preferably the latter is provided with a relatively short, hollow, threaded neck or collar portion to which a thin temporary cap may be detachably applied.The implant including the neck with the cap applied, is then inserted in a cavity formed in the jawbone of the patient to a depth where the implant is entirely submerged. Thereafter, the mucosa (gum) is laid over the cavity completely covering the implant and a suture is applied. After a suitable period of time which may be in the order of several weeks or even months, as determined by tests by the doctor or surgeon in charge, the covering skin is removed from the cavity and the temporary cap is replaced by a tooth-receiving head member, a portion of which projects above the surface of the gum. An artificial tooth or other dental device is then applied to the head member. Suitable tools may be employed in applying the caps and the head member and in removing the caps.
Abstract:
An angulation head for removable attachment to a dental implant of a type having a hollow interiorly threaded neck integrally attached to an implant portion comprises a stem at least a portion of which is exteriorly threaded and adapted to be screwed into the hollow neck, an integral cap, or flange to set on top of the neck and a bendable upstanding head portion which is adaptable to be bent angularly with respect to the cap and stem by use of a manual bending tool. The bending tool comprises a hand held elongated holder for the angulation head and an elongated bending shaft for bending the head portion. The hand held holder includes an elongated handle having at one end a flat surface normal to the axis of the handle and an axial socket extending inwardly from said flat end for receiving the stem of the angulation head with the cap seated on the flat end, the socket having interior threads for engaging the threaded portion of the stem. The elongated bending shaft has an axially extending socket at one end which is closed at its inner end and which is open at its outer end to snugly receive the bendable head portion of the angulation head.
Abstract:
Prosthetic devices, such as orthopedic, dental and maxillofacial prostheses, are provided which are composed of an inner load bearing, functional component and an outer foamed or sintered porous coating of selected bioengineering thermoplastics. The bioengineering thermoplastic coating is provided in regions where long-term bone fixation is desired by tissue ingrowth. The coatings offer substantial biomechanical advantages over any material system previously reported. Also provided, are anatomically shaped devices comprised totally of bioengineering thermoplastics with select porous areas; these devices include bone gap bridges, bone caps, and alveolar ridge augmentation implants.
Abstract:
A prosthetic dental implant which is surgically implantable in the maxillary and mandibular alveolar bones, providing a support base with a protruding post to which one or more prosthetic crown replacements are to be mounted. The implant is a high purity, high density, low porosity unitary alumina body having a serrated base. Its integral top is formed to provide an upwardly extending post with a truncated ellipsodially conical configuration for the attachment of a prosthetic tooth crown. The serrated side walls of the base are formed with outwardly projecting protrusions. These protrusions have a serrated or saw toothed cross sectional configuration with alternating horizontal surfaces and downwardly and outwardly tapering oblique surfaces.
