A method of producing a dental object (100), including the steps of producing a pillared support structure (101) on the dental object (100); and producing a lattice structure (103) for reinforcing the support structure (101).

An article of manufacture includes an upper arch of prosthetic teeth having a first end and a second end. A first temporary saddle extends from the first end and is configured to engage a first hamular notch of a patient. A second temporary saddle extends from the second end and is configured to engage a second hamular notch of the patient. The upper arch is configured to pivot with respect to the first and second hamular notches until the upper arch achieves an anatomically correct angle within a mouth of the patient. In certain embodiments, a reference member such as tabs and/or a nasal spine saddle is incorporated into the upper arch to assist in achieving the correct angle. A method for installing or placing the upper arch of prosthetic teeth described above in a patient is also disclosed.

A holding device (100) for a cylindrical blank (200), including a cylindrical recess (103) for inserting the blank (200); and a straight slot (105) intersecting the cylindrical recess (103) beyond the central point.

Method for manufacturing dental prostheses, comprising the following operations: defining a layered numerical representation of a dental prosthesis (11); for a first layer of the numerical representation, prepare a corresponding layer of a light sensitive liquid substance (6); selectively solidify the layer of liquid substance (6) to obtain a first sheet (7) having a geometry corresponding to the geometry of the first layer of the numerical representation; repeat the operations of preparing a layer of liquid substance (6) and selectively solidify the layer of liquid substance (6) for each subsequent layer of the numerical representation to obtain corresponding sheets (7); cause the mutual adhesion between said sheets (7); modify the composition of the liquid substance (6) after having solidified one of the sheets (7) and before solidifying the subsequent sheet (7), so as to modify one or more optical properties of the liquid substance (6).

A lower region of a temporary abutment includes an anti-rotational feature for non-rotationally mating with a dental implant. An upper region of the temporary abutment includes a first anti-rotational structure and at least one retention groove. A top surface of the temporary abutment includes one or more informational markers that provide information concerning the dental implant. A temporary abutment cap is configured to be coupled to the upper region of the temporary abutment. The temporary abutment cap has at least one projection configured to mate with the at least one retention groove of the temporary abutment. The temporary abutment cap has a second anti-rotational structure that is configured to slidably engage the first anti-rotational structure of the temporary abutment. The temporary abutment cap is configured to be coupled with a temporary prosthesis such that the temporary prosthesis and the temporary abutment cap are removable from the temporary abutment.

Systems and methods including an abutment blank clamping system for securing a abutment blank are disclosed. According to one example, the abutment blank clamping system includes an abutment holder including a base portion and an elongate clamping portion extending from a first end adjacent the base portion to a second end. The elongate clamping portion includes at least one bore extending from a first side surface defining a first opening to a second side surface defining a second opening, and at least one projection extending from the second side surface positioned adjacent to the second opening, the at least one projection configured to engage with the abutment blank.

A porous, silicate, ceramic body, optionally with different colors, with a first density, can be sintered into a silicate, ceramic body with a second density, wherein the ratio of the first density to the second density is 2/5 to 98/100, and the three-point bending strength of the porous, silicate ceramic body with a first density, measured according to ISO 6872, is 25 to 180 MPa.

The invention relates to a method for constructing tooth surfaces of a dental prosthesis and for producing dental restorations, starting from a 3D data record of an upper mandible layout and a 3D data record of a lower mandible layout, each layout comprising a number of teeth arranged in each mandibular arch and the teeth of the upper mandible layout and the teeth of the lower mandible layout at intercuspation making contact with each other at multiple contact points. The contact surfaces are selected by approximation. Relevant surface pairs lying opposite one another are identified and are incorporated by an optimization algorithm into local minimum distances, taking into consideration surfaces that can slide past one another. This allows the desired contact points to be produced. Surfaces that have not been selected are not considered in the production of the points of contact.

A lithium silicate glass ceramics having lithium disilicate as main crystal phase and having not more than 40 wt.-% of lithium disilicate crystals.

A dental model and related systems and methods, including a first component representing a portion of a patient's jaw and a second component that is demountably attachable to the first component, and a second component representing a dental structure of interest, such as the remaining portion of a tooth or a dental implant.
