  • Publication number: 20140011161
    Abstract: A method of forming a nanocrystalline surface on an implant is disclosed. The method comprises the act of roughening at least a portion of the implant surface to form a roughened surface. The method further comprises the act of, without forming an alkoxide on the roughened surface, depositing nanocrystals on the roughened surface. The nanocrystals comprise a material having a property that promotes osseointegration.

  • Publication number: 20130323678
    Abstract: A dental implant system including an implant and an abutment is disclosed. The implant includes a generally cylindrical body, a central axis, a distal end for anchoring in a patient's bone and a proximal end opposing the distal end. The proximal end includes a roughened lateralized surface that surrounds an abutment-engaging region. The lateralized surface is disposed at a negative slope relative to the central axis. The abutment includes an upper portion for supporting a tooth-like prosthesis and a lower portion for engaging the abutment-engaging region of the dental implant. The diameter of the lower portion of the abutment is smaller than the diameter of the implant at its proximal end. The lower portion includes a first surface with a soft-tissue enhancing material. The first surface and the lateralized surface defining a circumferentially extending recess having a V-shaped cross-section for receiving and attachment to the soft tissue.

  • Publication number: 20130248487
    Abstract: A method of forming an implant to be implanted into living bone is disclosed. The method comprises the act of roughening at least a portion of the implant surface to produce a microscale roughened surface. The method further comprises the act of immersing the microscale roughened surface into a solution including potassium hydroxide to produce a nanoscale roughened surface consisting of a web-like structure superimposed on the microscale roughened surface. The nanoscale roughened surface has a property that promotes osseointegration.

  • Patent number: 8425230
    Abstract: The present inventions is an abutment for use with a dental implant. The abutment comprises a prosthetic portion adapted to support a prosthesis thereon and an insert. The prosthetic portion has a subgingival end and a supragingival region for protruding beyond gingiva adjacent to the dental implant. The prosthetic portion has a passageway extending therethrough. The passageway includes an enlarged retention groove and non-round section. The insert extends into the passageway and engages the subgingival end of the prosthetic portion. The insert includes flexible retention fingers that, upon insertion into the passageway, initially contract before reaching the enlarged retention groove and then expand outwardly into the enlarged retention groove to hold the insert onto the prosthetic portion. The insert also has a non-round section for mating with the non-round section of the passageway.

  • Publication number: 20130004916
    Abstract: A dental restoration system is disclosed including an implant for attachment to a jaw bone of a patient. The implant includes a cylindrical body having an interior bore formed between a distal end and a proximal end. An abutment includes an interior bore formed through the stem and the post and an interface section interfacing with the abutment interface of the dental implant. An abutment removal insert has a cylindrical end insertable into a groove formed in the interior bore of the abutment. An abutment removal tool screw is insertable within the abutment removal insert. The abutment removal tool screw includes a grip and an opposite end. The opposite end causes the abutment removal insert to contact the abutment. The grip is rotatable to cause the opposite end to create force against the implant to cause the abutment to be detached from the implant.

  • Publication number: 20090075236
    Abstract: A dental implant system employs an improved abutment screw with acceptable biocompatibility, corrosion, strength, and preload characteristics. In particular, embodiments provide a dental implant system having an artificial implant and an abutment which are fastened with a screw formed from stainless steel, such as surgical grade 316L stainless steel. In some embodiments, the stainless steel screw is coated with a malleable material, such as gold, silver, or polytetraflouroethylene, to improve screw preload. Alternatively, the stainless steel screw may be coated with a harder material, such as diamond like carbon (DLC), amorphous diamond, crystalline diamond, or a combination thereof, which provides a low coefficient of friction providing improved preload properties.
