  • Patent number: 10335254
    Abstract: A dental implant has a hollow shell with outer bio-compatible surface for engaging a soft tissue socket left in gingival tissue after a tooth has been extracted, to promote healing. The shell tapers outwardly from a first to a second perimeter, the second perimeter being asymmetrically scalloped with opposite distal and mesial peaks and opposite lingual and facial valleys between the peaks. A dental implant in the bone socket left after tooth extraction is rigidly connected to a temporary post, the temporary post extending in the shell. The shell engages against the soft tissue socket without gaps and without requiring alignment between the shell and implant axes.

    Abstract: 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.

  • Patent number: 9173723
    Abstract: 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.

  • Patent number: 9108361
    Abstract: 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.

  • Patent number: 9055985
    Abstract: 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.
