  • Patent number: 11602420
    Abstract: A dental implant assembly containing an integrally-formed universal abutment which has a top section, a bottom section integrally joined to the top section, and a passageway extending through these sections. The passageway is formed by different size bores, initially a larger size than decrease in size. The top section of the abutment has a cross-sectional shape substantially like a polygon; the shape is formed by alternating linear and arcuate walls joining to a bottom section having a cross-sectional shape substantially like a polygon.
    Type: Grant

  • Patent number: 7207800
    Abstract: A dental implant assembly with an an abutment head integrally joined to an implant body. The top section of the abutment head a shape formed by a linear wall adjacent to an arcuate wall; a ledge is located beneath the top section of the abutment; and the abutment head extends above the ledge a distance of from about 2 to about 4 millimeters. The implant body has a base section and a neck section, each of which has a different degree of roughness.

  • Publication number: 20020039718
    Abstract: A dental implant system and additional methods of attachment are disclosed. The dental implant system includes an implant-abutment device, healing ball, analog abutment, retaining screw and guide pin. The universality of the system significantly reduces the number of surgical and prosthetic interventions and overall time of completion associated with the methods of attachment. As such, the device and procedures are simple, predictable and highly effective. Further, operative risks, pain, and infections are reduced, thereby improving patient recovery time and quality of life.
