  • Patent number: 9918809
    Abstract: An insert for a dental prosthesis screwed onto an implant, in particular of the type having a superstructure and an implant to be integrated in the bone, which are reciprocally joined by a screw. The insert is composed of an element made of a damping material interposed between the coupling surface of the superstructure and the implant. With an insert according to the invention, a dental prosthesis screwed onto an implant is obtained, which reproduces the natural anchoring state of the tooth to the bone, so that the stress peaks on the superstructure are damped before being discharged onto the implant and consequently also onto the bone. An insert according to the invention also offers the advantage of sealing the contact area between the superstructure and the implant, thus preventing dangerous bacterial infiltrations.

    Abstract: Dental implant fabrication and insertion methods and a personalized dental implant for use in such methods. Such a personalized dental implant is prefabricated by a computer-operated milling machine using a computer model generated using digital images taken of a dental patient's natural tooth in situ. After the natural tooth is extracted from the dental patient's mouth, the personalized dental implant is immediately inserted into the socket created by the extraction. Insertion of this dental implant immediately after the extraction obviates the need for multiple oral surgeries, avoids delicate structures, and is less invasive. Moreover, since this dental implant is custom fitted for the socket, osseointegration is expedited and the risk of bone collapse is reduced.

  • Patent number: 7179089
    Abstract: An abutment system for a dental implant includes an abutment having a base portion that is engageable with a dental implant and a shoulder disposed about the base portion that includes a hybrid ceramic material. The hybrid ceramic material includes at least 85% porcelain. An opaque can be applied to the exterior surface of the abutment. A pigment can also be added to the hybrid ceramic material so as to match the color of the patient's gum tissue. A method of preparing an abutment system includes the steps of forming a curable hybrid ceramic material into a shoulder about the base portion of an abutment, partially curing the hybrid ceramic material so as to form an initially cured shoulder, shaping the initially cured shoulder to a desired shape so that the shoulder conforms to at least one patient specific criterion, and completely curing the shoulder. A plurality of abutment systems may be assembled into a kit.

  • Patent number: 7090494
    Abstract: An implant includes an implantable body portion adapted to be at least partially recessed within a patient's alveolar bone, and which has a peripheral surface portion, which is configured to stimulate and/or facilitate the engagement of osteoblasts and other bone tissues with the implant. The implant body provides bone engaging regions along one or more of the distal and/or mesial implant surfaces, which are elongated relative to bone engaging regions on the lingual and/or buccal surfaces of the implant body. In particular, the implantable portion of the implant body includes a bone engaging surface which, when the implant body is fully seated within the patient's jaw bone, extends from a distal portion of the implant body to a remote proximal-most edge. The proximal-most edge has a contour selected to generally follow a predetermined crestal outline of the supporting bone tissue.

  • Patent number: 6343931
    Abstract: Plugs for use in sinus lift and augmentation techniques have a mushroom-like shape and having of a substantially cone-shaped body with an integral head of enlarged diameter. The plugs are preferably formed of donor cadaver bone, osteosite or hatogens. The plugs, in one embodiment, are formed of universal sizes and are preferably “CAD CAM” cut, based on a scan of the orifice. The plugs have a fluted or corrugated-like periphery and are preferably swaged into a previously prepared cavity, the fluted configuration preventing rotation of the plug. An implant is then counter-sunk into the core plug. The core plugs, once in place, promote bone growth and integration as self to enhance and provide a bed of rich bone in compromised and deficient areas structurally and esthetically. A set of tapped drills range from 2.8 mm up to 7.5 mm in diameter and lengths of 8 mm-15 mm can be used and standard plugs can be used in place of CAD CAM (i.e., “custom”) cutting.

  • Patent number: 6089867
    Abstract: This invention pertains to a tooth implant which is obtained from a donor's jawbone. The tooth implant includes the root of the donor's tooth with the crown detached therefrom and a portion of the donor's jawbone which surrounds the root and is attached thereto. The implant is obtained by carefully harvesting the root with the attached portion of jawbone surrounding the root as a single unit from a donor individual. The tooth implant is implanted into an opening in a recipient's jawbone. Upon healing, the implant is firmly and permanently attached to the bone tissue of the recipient. The root of the implant may then be used to affix a prosthetic crown within the jawbone of the recipient.

  • Patent number: 6042380
    Abstract: An expandable dental implant which is less traumatically inserted and can immediately receive functional loading to support a dental prosthesis upon insertion into the patient's mouth. The expandable implant is constructed as an inflatable balloon, which has a first, relatively smaller diameter prior to insertion into the patient's mouth. The implant is provided with an insertion end, for insertion into a formed bore in the patient's jaw bone. Upon insertion into the bone, the balloon can be inflated into a second, larger diameter profile by filling the hollow interior of the balloon using an appropriate hardening material, which applies pressure against the interior walls of the implant, allowing the implant to inflate within the bone and to fixate. Upon inflation of the implant, a dental crown can immediately be added to the implant's attachment end.

  • Patent number: 5951288
    Abstract: The present invention is a dental implant inserted into the jaw bone for anchoring an artificial tooth in the bone. It has been designed to overcome the difficulties and complexities of prior art implants. The inventive implant consists of three simple components: An elongate body which has an neck portion and a root portion; an abutment which is mounted to the neck portion of the body and which receives the temporary or permanent replacement tooth; and a screw which secures the abutment to the body. The root portion of the body consists of multiple legs and is formed from a shape memory alloy. Use of shape memory alloy allows the root portion to assume a closed, elongate shape at cool temperatures and to assume an open, fanned shape at temperatures typical of the human body. The inventive implant is maintained at cool temperatures until and during insertion into the body allowing an easy and non-traumatic placement of the implant.
