  • Patent number: 6273720
    Abstract: A dental implant system including an implant having an incisal portion for insertion into a alveolar receptor site formed in the jawbone to receive the implant, a collar having a beveled shape extending superiorly from the incisal portion with a smooth polished surface, a threadless cavity extending from the occlusal end of the implant partially into said embedded incisal portion with the cavity having a recessed groove adjacent the proximal end of the incisal portion, a removable healing cap adapted to be placed into the threadless cavity of said implant with said healing cap having a resilient shoulder projecting therefrom to engage said groove for forming a sealed interlock during an extended healing period and a single post abutment member for insertion into the threadless cavity of the implant after removal of the healing cap.

  • Patent number: 6053733
    Abstract: A dental implant with a straight cylindrically shaped upper end finishing off in a hexagonal projection, with both being axially perforated in alignment with the screw-threaded stem. The perforation does not exceed the lower end of the cylindrical portion and the screw-threaded stem can be made with an appreciably smaller diameter than the conventional one. The apical (apexial) end of the stem is conical and is finished off by a small chamfer or bevel. This favours reaching the cortical area of the bone, increasing the guarantees of its immobility, as well as performing a better crushing and grinding of the bone.

  • Patent number: 5989030
    Abstract: A dental implant of which body has a form tapering toward its top and has a plurality of mountain-shaped projections emissively; said projections being cut off in its center, and ridge line portions of said projections which contact with compact bone portion of an alveolar bone at the time of insertion, being in a shape that said ridge lines increase its size upwardly; and a head for supporting an artificial tooth. The implant is useful for repairing lost canines.

  • Patent number: 5975904
    Abstract: An articulated bone reconstruction bar includes a series of short segments connected by fixable axles. The length of the bar is adjusted by varying the number of segments. Before the fixable axles are tightened, the bar is positioned across a discontinuity on a bone. It is adjusted to match the contour of the bone, and the fixable axles are tightened to fixate the connections between the segments and make the bar rigid. The bar is then attached to the bone with mounting screws extending through the segments. Fixable axles with long posts may be used for mounting a dental support plate at the gum line in an area where bone has been lost or removed. If failure occurs, the fixable axles enable the broken segments to be replaced without replacing the entire bar.

  • Patent number: 5944526
    Abstract: The dental implant system includes a saddle-shaped support member that fits over the patient's jaw bone and has a shallow depression into which an anchor for a prosthesis is inserted. A cover plate, with an opening for access to the anchor, fits over the anchor and a portion of the support. The system is held in place by retaining wires that wrap around the patient's jaw bone and over the cover plate. The wires supply rigidity to the system. The anchor is threaded, such that a crown abutment can be screwed to the anchor through the opening in the cover plate and thereby positioned on the jaw. The dental prosthesis is then attached to the crown abutment in a conventional manner.

  • Patent number: 5906489
    Abstract: An implant for supporting a prosthesis includes a base sheet that has a longitudinal axis and a lateral axis. At least two holes extend through the base sheet. A post is connected to the base sheet. The temporary dental implant is installed over a patient's jaw bone by exposing the jaw bone by displacing covering tissue. The base sheet is shaped into a U-shape so that the legs of the U-shape are directed away from the post. The shaped base sheet is installed over the jaw bone by securing the covering tissue to the jaw bone and loading a prosthesis onto the post.

  • Patent number: 5853291
    Abstract: A subperiosteal bone anchor has a base that is thin and moldable so the base can be conformed to bone where it is to be placed. The base is formed as a plurality of arms, and leaves with central holes in the leaves so screws can urge the leaves against the bone. The edges of the base are scalloped, and very thin to facilitate bone overgrowth. Central to the arms is a stem extending up, and having a variety of connection mechanisms for attachment of orthodontic appliances.

  • Patent number: 5785525
    Abstract: An implant body has a non-round cross sectional shape, for example, ovoidal or rectangular. Lateral surfaces of the implant include threaded portions of a circular cylinder such that the implant, although non-round in cross section, can threadably engage a tapped circular opening in the jawbone leaving lateral spaces. Bone grows into the spaces between implant and the jawbone socket. The implant is shaped similarly to the root structure of a natural tooth and can be oriented, about its longitudinal axis, at any angle relative to the general curvature of the jawbone where the implant is seated. A more natural appearance of the mouth is achieved; prosthetic teeth may be positioned closer together without loss of strength between the implant and the jawbone. A non-round cross section of an implant opening receives an abutment post of corresponding cross section to prevent rotation of the abutment relative to the implant. A cemented connection prevents axial displacement between the abutment and implant.

  • Patent number: 5769637
    Abstract: Prosthetic apparatus for promoting and supporting guided bone tissue regeneration in at least missing or excised portions of the human mandible or maxilla and in bony defects of the mandible and maxilla. The apparatus includes a bone attachment tray formed of tissue-biocompatible titanium sheet material having perforations therethrough for receiving bone screws to affix the tray to stump portions and ridge sections of the mandible or maxilla proximate the missing or excised stump portions or ridge sections and one or more tissue-biocompatible metallic dental tooth root replacement implants which are releasably affixed at one end to the inner surface of the tray and which depend from the tray into the missing or excised portions or bone defects of the mandible or maxilla for incorporation and support in bone tissue regenerated within the tray.
