Soft tissue preservation temporary (shell) immediate-implant abutment with biological active surface
Patent number: 9452032Abstract: An immediate dental implant shell has outer, multiple zones for engaging a soft tissue socket left immediately after tooth extraction from a bone socket. The zones have combinations of different biologic agents, macro- or micro-geometric, or micro- or macro-morphology irregularities to better engage gingival sulcus, junctional epithelium and dento-gingival fiber zones of the soft tissue socket. The shell may also have various guide markings and projections to aide drilling of the implant hole in the bone socket. A dental implant is placed in the drilled implant hole before or after the shell has been placed in the soft tissue socket, and has an axis that is independent of the shell axis so the shell and implant both sit in optimum positions in their respective soft and bone sockets.Type: GrantFiled: June 27, 2013Date of Patent: September 27, 2016Assignee: BIOMET 3I, LLCInventors: Mark N.

Patent number: 9436868Abstract: Described are methods that enable rapid automated object classification of measured three-dimensional object scenes. Each method can be performed during a three-dimensional measurement procedure while data are being acquired or after completion of the measurement procedure using the acquired data. In various embodiments, an object scene is illuminated with an optical beam and an image is acquired. In some embodiments, the object scene is illuminated with a structured light pattern and a sequence of images of the object scene illuminated by the pattern at different spatial phases is acquired. Coordinates are determined for points in the one or more images and a translucence value is determined for each of the points. An object class is determined for each point based on the translucence value for the point. Optionally, additional information, such as grayscale or color image data for each point, is used to supplement the object class determination.Type: GrantFiled: August 25, 2011Date of Patent: September 6, 2016Assignee: Dimensional Photonics International, Inc.Inventors: Robert F. Dillon, Bing Zhao

Patent number: 9358082Abstract: A method, system and computer program of planning a dental prosthesis in a patient are disclosed, including steps, units or code segments for virtually planning a dental prosthesis. Envelope data is provided of an envelope guide, including data corresponding to a support surface for facial tissue, which is desired to result when the dental prosthesis is installed in the oral cavity of the patient. An outer envelope of a desired dental prosthesis in the oral cavity is simulated based on the envelope data. A desired dental restoration is provided and adjusted in a virtual environment relative to the simulated outer envelope, and dental prosthesis data is generated based on the adjusted desired dental restoration usable for producing the dental prosthesis.Type: GrantFiled: November 15, 2010Date of Patent: June 7, 2016Assignee: NOBEL BIOCARE SERVICES AGInventor: Urban Nilsson

Patent number: 9173723Abstract: A cradle, assembly, system and method for installing a prosthesis at a surgical site. The cradle temporarily engages the prosthesis and holds it in the correct orientation and position adjacent the surgical site. An aperture is defined in the cradle and a portion of the prosthesis is received therein. In one embodiment, the cradle, assembly and system are used to install a final dental prosthesis in a patient's mouth in a single visit to the dentist's office. A securement member pins the surgical template and subsequently the cradle to the jaw. A metal sub-structure on the final dental prosthesis is received in the aperture in the cradle. Cylinders attached to implants anchored in the jaw extend through holes in the sub-structure and are bonded to the prosthesis. The cradle is detached from the jaw and from the prosthesis prior to screws being re-inserted through the cylinders and into the implants.Type: GrantFiled: October 10, 2012Date of Patent: November 3, 2015Inventor: James Harrison

Patent number: 9108361Abstract: A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. An intra-oral scan is made of the patient's mouth having an installation site with a dental implant installed and a healing abutment attached to the dental implant. The healing abutment has at least one informational marker. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker and the three-dimensional model are used to manufacture a rapid prototype model of the patient's mouth, which includes a dental implant analog.Type: GrantFiled: September 19, 2014Date of Patent: August 18, 2015Assignee: Biomet 3i, LLCInventors: Theodore M. Powell, John T. Amber, Bruce Berckmans, III, Zachary B. Suttin

Patent number: 9055985Abstract: A dental implant assembly comprises an implant body adapted for securement within a bore in a jaw bone of a patient. The implant body has a portion with an external thread for engaging the bore. An abutment has a top portion and a bottom portion. The top portion of the abutment is adapted to secure a prosthetic component. The bottom portion of the abutment is attachable to the implant body and adapted to be positioned below a gumline of the patient, the abutment formed of a first material. A cover is sized and shaped to cover the bottom portion of the abutment and adapted to be positioned below the gum line, without covering the top portion of the abutment. The cover is formed from a second material having a different color from the first material.Type: GrantFiled: November 17, 2011Date of Patent: June 16, 2015Inventor: Sargon Lazarof
