  • Patent number: 8352060
    Abstract: A method and system for fabricating a dental prosthesis are provided. High resolution digital scanned images of a patient's oral structures are acquired. Three dimensional (3D) cone beam X-ray images of hard and soft oral tissues are acquired. The scanned images are integrated with the 3D cone beam X-ray images in a 3D space to obtain combined three dimensional images of the oral structures. The occlusal relationship between upper and lower oral structures are digitally simulated using the combined three dimensional images. The dental prosthesis is digitally modeled for planning intra-oral positioning and structure of the dental prosthesis. The digital dental prosthesis model is refined based on simulated force tests performed for assessing interference and retention of the digital dental prosthesis model. A prospective dental prosthesis model is created based on the refined digital dental prosthesis model. The dental prosthesis is fabricated based on a verified prospective dental prosthesis model.

  • Patent number: 8244017
    Abstract: A computer implemented method and system for constructing a three dimensional (3D) tomographic image from an object's two dimensional (2D) panoramic image are provided. A first geometrical attribute set in a first coordinate system is assigned to one or more focal troughs. A second geometrical attribute set in a second coordinate system is assigned to the 2D panoramic image. Second geometrical attributes are correlated with first geometrical attributes for reconstructing the 2D panoramic image in multiple dimensions. Multiple defocused elements of the object are determined along the 2D panoramic image's horizontal dimension. A transverse dimension is determined for the reconstructed panoramic image by mapping the defocused elements to a translation along the transverse dimension in the first coordinate system on either side of the center of the focal troughs. The multiple dimensions of the reconstructed panoramic image are transformed into an orthogonal coordinate system to generate the 3D tomographic image.

  • Publication number: 20120064485
    Abstract: A dental implant and a method and system for fabricating and installing the dental implant are provided. The dental implant comprises an implant member for insertion into a periodontal bone socket, and an anchoring assembly. The anchoring assembly is positioned within a hollow axial cavity of the implant member. The anchoring assembly comprises a fastening element and radial and equidistant cylindrical members. The fastening element engages the implant member within the hollow axial cavity. The cylindrical members are positioned proximal to the implant member's root section. The root section comprises through-holes for radially and forcibly sliding the cylindrical members through them. Each of the cylindrical members comprises a first end interfacing with the fastening element, and a second end interfacing against a periodontal bone socket surface. When the fastening element apically advances within the hollow axial cavity, the cylindrical members generate an anchoring force to anchor the dental implant.
