Patent number: 5695336Abstract: A dental implant fixture intended for installation in maxillary and mandibular posterior regions where bone is cancellous internally and cortical externally characterized by buccal and lingual cortical plates bounding a relatively large body of cancellous bone. The body of the implant fixture has a width dimension that is substantially the same as the distance between the buccal and lingual cortical plates in the site of installation and has a stop flange of substantially the same width at its gingival end. When the implant is installed in that site the stop flange makes bone-to-implant contact with the coronal bone which joins the plates. The length of this implant fixture is limited so that when so installed it does not make contact with the mandibular canal or the sinus cavity.Type: GrantFiled: February 15, 1996Date of Patent: December 9, 1997Assignee: Implant Innovations, Inc.Inventors: Richard J. Lazzara, Keith D. Beaty

Patent number: 5685714Abstract: A support post for use with a dental implant for supporting a prosthesis thereon is disclosed. The support post includes an implant-contacting region and a supragingival core section which extends from the trans-tissue region for supporting a prosthesis. An interface member is secured to the post at the bottom of the implant-contacting region for abutment between the implant-contacting region and an implant to which the post is to be secured. The interface member has material properties different from those from which the post is made and compatible with those of the implant. Typically the support post is made of ceramic material while the insert is made of titanium having hardness properties no greater than that of the implant with which it is used.Type: GrantFiled: July 2, 1996Date of Patent: November 11, 1997Assignee: Implant Innovations, Inc.Inventors: Keith D.

Patent number: 5582299Abstract: A dental implant packaging system for contamination-free packaging, storage, transport and delivery of dental implants and related components. Various embodiments of the system as applied to a dental implant and its cover screw are shown in which a dental implant is housed in a transparent tubular capsule that is lined with a titanium sleeve which covers the head and part of the body of the implant, leaving the tail end exposed to view. The head is restrained in the opening into the capsule and a cap which closes the capsule also serves to hold the head in place.Type: GrantFiled: October 3, 1995Date of Patent: December 10, 1996Assignee: Implant Innovations, Inc.Inventors: Richard J.

Patent number: 5188800Abstract: The dental implant system of the present invention has a decreased surface contact angle and includes a biocompatible titanium implant which has been treated by the plasma cleaning and sterilization process of the present invention.An implant that has experienced plasma cleaning and sterilizing has improved retentive abilities over traditionally cleaned implants. The surface of the implant is now free of all organic debris, has increased wettability, contacts more bone-forming cells upon placement, and has stronger bonds between the metal surface and the bone-forming liquid cells. As a result, the implant becomes more intimately involved with the surrounding bone and tissue structure.The implant is comprised of an inert, biocompatible titanium material that is designed of such dimensions and angulations to maximize contact the bone cells and subsequently attach a well-suited mechanical prosthetic system to it.Type: GrantFiled: October 10, 1991Date of Patent: February 23, 1993Assignee: Implant Innovations, Inc.Inventors: Ralph E. Green, Jr., Ronald H. Jones, Leland J. Peters, Peter J. Withol

Patent number: 5105690Abstract: A driver for screws, bolts and the like which have a socket for receiving the bit of a driver, in which a tapered holding section between the bit and the shaft of the driver serves to hold an article by frictional engagement with the opening edge of the socket when the bit is engaged in the socket for turning the article. The bit is shorter than the depth of the socket, and the holding section expands sufficiently away from the bit so as to make frictional contact with the edge of the socket when the bit is engaged in the socket.Type: GrantFiled: March 29, 1991Date of Patent: April 21, 1992Assignee: Implant Innovations, Inc.Inventors: Richard J.

Patent number: 5040983Abstract: A dental coping in the form of an elongated tubular body has a base portion adapted at a first end of the body to mate with the gingival aspect of the patient's implant fixture, and a thin-walled tubular portion extending to the other end of the body supragingivally from the base portion when the base portion is so mated. The base portion is substantially rigid, having a thicker sidewall than the thin-walled tubular portion. A shoulder is provided within the base portion, for cooperating with a bolt to fasten the coping to the implant fixture. A flange extends radially from the coping, preferably from the rigid base portion, for fixing in place a temporary restoration formed around the coping. The fabrication and use of fixed provisional restorations in partially edentulous patients undergoing treatment with osseointegrated fixtures is described.Type: GrantFiled: January 23, 1989Date of Patent: August 20, 1991Assignee: Implant Innovations, Inc.Inventor: Paul P. Binon

Patent number: 5022860Abstract: Dental implant fixtures having external diameters less than 3.0 mm., and external threads which are deeper at the apical end of the fixture than elsewhere are described. The deeper threads near the apical end serve to pull the fixture into a prepared bore in the patient's jawbone. There results a firm close contact between the fixture and the host bone to promote osseointegration. Ultra-slim implant fixtures are provided which can be used in thin sections of human jawbone where dental implants were previously contra-indicated.Type: GrantFiled: December 13, 1988Date of Patent: June 11, 1991Assignee: Implant Innovations, Inc.Inventors: Richard J. Lazzara, Keith D. Beaty
