A cap mountable on and detachable front an intraoral scanner including a housing having an opening for connecting to at least a part of the intraoral scanner, a measurement window provided in the housing and located opposite to the opening, and a mirror that reflects light from the measurement window toward the opening. The housing has a longitudinal length shorter than that of a probe defining a depth-of-field, of the intraoral scanner extending from the measurement window to a predetermined extent.

The invention relates to a process of producing a dental zirconia restoration, the dental zirconia restoration having an outer and an inner surface, the process comprising the step of firing a porous dental zirconia restoration and a glass until the porous dental zirconia restoration is sintered, the glass being located during the firing step on at least a portion of the outer surface of the porous dental zirconia restoration, wherein the zirconia material of the porous dental zirconia restoration and the glass are selected such that during the firing step the glass infiltrates the pores of the porous dental zirconia restoration to an extent of not more than 5 m in depth. The invention also relates to a sintered dental zirconia restoration obtainable by such a process and a kit of parts comprising a porous dental zirconia mill blank and a surface treating agent containing a glass for use in such a process.

The invention provides a method for creating a physical teeth model. The method comprises the following steps: providing a virtual three dimensional (3D) representation of a patient's dentition that comprises at least a region of the teeth that includes a tooth stump on which a crown is to be fitted or a region on to which a bridge is to be fitted; and preparing a physical model of the jaws of a subject from a blank, based on information from said virtual 3D image.

A layered denture having at least one of an integrated layer, balanced occlusion, and a root approximating structure is disclosed. The resulting denture may be suitable for use without an underlying reinforcement bar and may provide enhanced aesthetics by approximating natural dentition and roots both above and below the gum line.

The secondary part (17) according to the invention, for securing on and/or in a dental implant, is suitable for receiving a tertiary part. The secondary part (17) comprises a secondary-part body (22) with a recess (21) on the inside, and a secondary-part screw (20) receiveable or received in the recess. The secondary part (17) has a screwing-in mechanism in the form of a contour for receiving a screwing-in tool for screwing the dental implant, connected to the secondary part (17), into a jawbone.

A method of making a dental restoration has the step of providing a precursor of the dental restoration. The dental restoration has at least a first and a second surface portion which are delimited by a physical boundary structure. The method further has the steps of applying a first coloring solution associated with the first surface portion onto the first surface portion, sintering the dental restoration precursor, and removing the physical boundary structure.

A method of making a physical object by additive manufacturing. The method has the steps of providing a light hard-enable primary material (11), building up the object (100) by successively hardening portions of the light hardenable primary material (11) by irradiating the portions with light, coating at least a part of the object (100) with a light permeable coating or oxygen protective material; and irradiating the coated object (100) with light and thereby post-hardening any light hardenable material (11).

The secondary part (17), for securing on and/or in a dental implant, is suitable for receiving a tertiary part. The secondary part (17) has a secondary-part body (22) with a recess (21) on the inside, and a secondary-part screw (20) receivable or received in the recess. The secondary part (17) has a screwing-in mechanism in the form of a contour for receiving a screwing-in tool for screwing the dental implant, connected to the secondary part (17), into a jawbone.

Provided are a dental technical fee automatic calculation system, a dental technical fee automatic calculation method, and a program capable of estimating a basis of billing or a billing amount from an image of a prosthesis. The dental technical fee automatic calculation system 100 is provided with an image data input unit 110 configured to input image data of the prosthesis, a basis data input unit 120 configured to input basis data as a basis of assessment of a billing amount for the prosthesis, and a learning unit 130 to which the image data and the basis data are input to construct a learning model indicative of a correlation between the image data and the basis data.

A bendable impression tray includes a base portion and a handle portion. In one embodiment, the bendable impression tray includes a U-shaped portion and at least three projections extending outwardly from the U-shaped portion by at least 5 millimeters in bottom view. In one embodiment, the bendable impression tray includes a base portion that is substantially U-shaped in bottom view, and defines at least two peripheral notches, each extending inwardly from an outer periphery of the base portion by at least 5 millimeters in bottom view.
