摘要:
A container and apparatus for preparing dental prosthetics. The container comprises a body having an interior and a top edge, a penetrable lid sealably secured to the top edge and containing a quantity of glazing liquid mixture liquid less than a volume of the body and a quantity of gas having a density greater than air. The apparatus comprises the container, a lid penetrator operable to form at least one penetration through the lid at at least one dipping location, an arm adapted to hold at least one dental prosthetic and pass each dental prosthetic through the at least one penetration into and thereafter out of the glazing liquid mixture, and wherein the arm is adapted to move the at least one dental prosthetic in a drying path after dipping in the glazing liquid mixture so as to form a consistent glazing layer thereover.

A method for designing and manufacturing implant based restorations is disclosed. The method involves the use of Scannable Temporary Anatomic References to provide very reliable, fixed points of reference to enable a technician to relate and superimpose the dental implant position to a pre-planned restoration with a very high degree of accuracy throughout the entire workflow. The method can be carried out by placing Scannable Temporary Anatomic References in a jaw, on teeth, and/or in implants, collecting images by scanning a mouth, relating those images to images of a appearance of desired dental implant based restoration, placing an implant in the jaw, scanning the scannable temporary anatomic references to create a new set of images, relating the images, and producing a restoration based on the images.

Optional : Auftragen einer Verbindungsschicht auf der Substruktur (2) und/oder Konditionierung der Substruktur (2); v. Materialauftrag, insbesondere Auftrag eines Kompositmaterials, auf die Substruktur (2) in einem 3D-Druckverfahren derart, dass sich die individualisiert zu fertigende dentale Ersatzstruktur (1) ergibt.
摘要:
The invention relates to a method to produce a dental structure with a cavity having a negative form of the structure, which is formed in an investment material, wherein flowable lithium silicate glass ceramic is pressed into the cavity. Thereby a compressive surface stress is created in the ceramic structure through the replacement of lithium ions by alkali ions, in that the model is enriched with alkali compounds and/or the model is covered with a layer of a material containing alkali ions.
摘要:
A method of using hardenable dental articles. The method can include placing a film (30) onto a dental structure (40) to cover at least a portion of the dental structure (40); providing a hardenable dental article (10); and applying the hardenable dental article (10) to the dental structure (40) covered by the film (30).
摘要:
A method of making a dental restoration has the steps of providing a three-dimensional model of a dental restoration, providing a three-dimensional virtual model (21) of an anterior incisal portion of a patient's tooth, superimposing the dental restoration model and the incisal portion model (21), and automatically recessing the dental restoration model, and thereby creating a reduced dental restoration model. The method helps combining the advantages of monolithic dental restorations and manual finishing.

Procédé de fabrication d'une prothèse dentaire sur implant, caractérisé en ce qu'il comprend une étape de fabrication de la paroi extérieure (E5) de la prothèse dentaire et une étape de fabrication d'au moins une connectique (E6) destinée à une fixation sur au moins un implant.
摘要:
The technology relates to modelling a prepared tooth for fitting a prosthetic thereon. A die, representative of a prepared tooth, may be modelled as a positive virtual three- dimensional die model (601). An impression of a set of teeth surrounding and including the prepared tooth may be modelled as a negative virtual three-dimensional impression model (501). The negative virtual three-dimensional impression (501) may be inverted to create a positive virtual three-dimensional impression model (503). The positive virtual three-dimensional impression model (503) and the positive virtual three-dimensional die model (601) may then be merged to create a virtual three-dimensional dentition model.
