  • Patent number: 6508650
    Abstract: An apparatus and method comprised of dental implant impression mounting hardware with a non-interfering, low profile for making time saving and accurate, simultaneous upper and lower impressions and bite registration, with the mouth completely closed and the jaw accurately positioned in centric closure. A low-profile, impression post is snapped within a matching low profile, winged and perforated impression cap held securely within a self-curing elastomeric impression material. The cured impression material retains the low profile impression cap which snaps free of the mating low profile impression alignment post. The impression post is removed and attached to an analog of the permanent endo-osseal implant and snapped back into low profile impression cap embedded in the elastomeric mold.

  • Patent number: 6309220
    Abstract: Attempts to install a secure implant post in thinned and receding bone can result in a weakening or loosening of a final restoration and a compromised cosmetic appearance. The current invention remedies the need to drill out a large hole and further thin the receding bone mass by a bone condensing and distension apparatus herein known as an implant distractor. Additionally, the current invention obviates the need for ridge augmentation procedures needed to increase bone mass prior to implant placement. In this invention, a smaller hole is drilled and a vertically sectioned, temporary implant distractor is installed. The implant distractor is split vertically into two or more sectors with cone-shaped concave tapered holes at the coronal and apical ends. A draw screw pulls a cone nut upward into a bottom tapered hole and pulls a typical healing plug with a cone shaped convex lower element into the upper tapered hole to force the implant distractor sectors outward and to expand the surrounding bone.

  • Patent number: 6213773
    Abstract: An apparatus comprised of dental implant impression mounting hardware with a non-interfering, low profile for making time saving and accurate, simultaneous upper and lower impressions with the mouth completely closed and the jaw accurately positioned in a resting position. A low profile cross bar or t-bar impression post snaps and holds securely within a self-curing elastomeric impression material, yet does not interfere with the taking of a simultaneous upper and lower elastomer impression of the accurately interdigitated jaw using a ‘triple tray’. The cross bar or t-bar mounts to a perimucosal extension of selectable height. The cross bar assembly and the extension accurately clock and lock to the mating endo-osseous implant fixture or to the implant analog for excellent registration.

  • Patent number: 5897320
    Abstract: A narrow channel is provided in an dental abutment post to allow excess dental cement to flow out of the interstitial space between the dental abutment and the overlying prosthesis. During the seating of the prosthesis the excess dental cement is channeled to and extruded from a preferred collection point for easy removal. Hydrostatic pressure and trapped gasses that would tend to lift the prosthesis into a non-fitting position or form a weakened cemented bond of uneven thickness are prevented by this apparatus and method to relieve pressure.

  • Patent number: 5885283
    Abstract: An apparatus and method to elongate and extend outward and downward a surgically transected forward section of the mandible with small daily adjustments to stretch the filamentary connective tissue between the divided sections of bone to correct severe malocclusion. The apparatus maintains a narrow gap between the separated sections of the mandible as the connective tissue is lengthened and mineralized forming new bone. The slowly widened gap has a chance to create new bone forming tissue to bridge the gap. By containing the apparatus within the oral cavity, advantages over cumbersome external apparatus become apparent. Infection and inflammation are easier to control within the oral environment. By clamping the apparatus to the ramus under the masseter muscles, no external facial scars result from externally applied surgical pins. Separate adjustments independently move the transected section of the mandible outward and downward.

  • Patent number: 5641287
    Abstract: An apparatus and method for the steady and accurate placement of a narrow smooth-walled slot in a bone structure by means of a hand held guidance template with a transparent slide to perpendicularly restrain a rotating cutting bit of a hand held tool while the transparent slide is drawn along a slot in the guidance template. The template is held in place with a light force through the guidance template handle and accurately positioned by means of serrated depth stops and perforated extensions bonded to a quick-setting resilient polymer conforming to the contour of the bone structure. Prevented from non-axial motion, the rotating cutting bit is plunged deeper to route a narrow smooth-walled slot in the bone structure. The primary use envisioned for the guidance template is in the accurate placement of an endosteal inline plate in the structural bone of the mouth for the attachment of permanent dental prosthetics.

  • Patent number: 5411332
    Abstract: A blending apparatus, inexpensive in construction and requiring a minimum of recirculation, is today essential for economical and thorough blending of particulate material, for example, plastic pellets of virgin material and of pellets that have been reconstituted from recycled material. Construction of the blender is low in cost because the customary receiver, and its piping, conventionally installed below the blender are eliminated. The novel convex baffle serves:(1) as a termination surface for the conventional perforated blending conduits; and (2) retains a toroidal annular volume of particulate material in position between the upper outer surface of the baffle and the inside wall of the blender. The particulate material passes through the blending tubes, drops into the blending area below the convex baffle, whereupon the small amount of particulate material in the toroidal block or "keystone joist" is released to proportionally blend with it.

  • Patent number: 5136747
    Abstract: A protective "bumper cover" for vacuum cleaners, used by janitorial building personnel in commercial locations to prevent damage to conventional office furniture and walls, has a top and sides made of a tough moldable plastic material, for example, a polyurethane, which can be molded with a resilient inner layer and a tough outer "skin," the inner layer yielding in the case of impact with furniture, thus absorbing the collision energy, the outer "skin" resisting cutting and damage to the bumper cover due to such impact. Apertures in the cover provide access to adjustment screws and for inspection of the driving motor brushes. Straps molded integrally with the cover can be secured to the vacuum cleaner itself at various suitable anchoring points.
