Abstract: The invention relates to a method to increase the strength of a form body of lithium silicate glass ceramic, which after it has a desired end geometry and after the application of a material which influences its surface to form a coating, is subject to a heat treatment. To create a surface compressive stress through the replacement of lithium ions by alkali ions of greater diameter at least that region not covered by the application layer is covered by a melt or paste consisting of or containing a salt of an alkali metal with ions of greater diameter and the form body is in contact with the melt or paste for a period of time t at a temperature T and the melt or paste is subsequently removed from the form body.

Abstract: A method, apparatus, system, and computer program product for automatically determining exposure time for an intraoral image. The method includes acquiring a low dose pilot projection image of an object to be imaged, performing a sanity check to ensure that a usable exposure is attainable, estimating a remaining exposure time required for an additional projection image, taking the additional projection image and adding the two images together to generate a final image wherein the dose delivered to the x-ray detector is influenced by patient specific dental anatomy.

Abstract: A method, system and computer readable storage media for determining articulator parameters. A dentist may use a mobile device such as a smart phone to quickly and inexpensively visualize a 3D model of a patient's face and jaw, with a depth sensor being used to detect depth information. Articulator parameters may then be obtained to be used for treatment planning based on an analysis of the correct functioning of the patient's teeth.

Abstract: The invention relates to methods for preparing a three-dimensional digital model of a prosthetic denture base for fabrication using a light-based three-dimensional printing apparatus. A virtual reference model of a prosthetic denture base is prepared and manipulated to establish specific spatial orientation and angular inclination with respect to the build platform surface of the printing apparatus. Methods may include performing a corrective digital scaling process on the virtual reference model in order to achieve further improvements to dimensional accuracy in the fabrication of prosthetic denture bases.

Abstract: A verification gauge for use in improving the accuracy of a 3D scan. A bar of adjustable length has a first and second ends that can be affixed between two points of the oral-cavity. The bar is scannable and has a visual indicia thereon to verify and determine the length and relative position between the two points.

Abstract: This invention relates to printable high strength/toughness polymerizable material systems for making dental products such as artificial teeth, dentures, splints, veneers, inlays, onlays, orthodontic appliances, aligners, copings, frame patterns, crowns and bridges and the like. A DLP, stereolithography, modified or their modification and combination based printer is used to cure polymerizable material in several different methods of this invention to build-up the object. The resulting three-dimensional object has good dimensional stability.

Abstract: A method and system for making a preformed dental membrane using three-dimensional (3D) patient data. A patient jaw having insufficient bone at a surgical site may be scanned to provide a 3D image which may be used to design a virtual preformed dental membrane and fabricate for placement over packed bone graft substitute.
