Preferably, the zirconia particles comprise 2.0 to 9.0 mol % yttria. Preferably, wherein the content of the liquid in the dispersion medium is 50 mass % or more.

The invention relates to a denture, made of teeth, in particular prefabricated teeth, and of a denture base made of a gingival material, comprising cavities for teeth in which cavities for the teeth are mounted, in particular attached by bonding, characterized in that the denture base (12) is produced by a CAD/CAM process forming the cavities (20) for the teeth (14), and in that cervical areas (40a) of the teeth (14) extending through the basal surface (16, 18) of the denture base (12) are removed, in particular abraded or milled.

The invention relates to a method for the production of a dental restoration from a blank, which has regions or layers of ceramic materials with differing compositions, under use of the method steps, filling of the ceramic materials into a mold, pressing of the ceramic materials to form a blank, removal of the blank from the mold, temperature treatment of the blank, wherein the ceramic materials are filling into the mold in such a way that layers and/or regions after temperature treatment have a profile that is available as a digital set. There is then a virtual contouring of the dental restoration taking shrinkage into account, a virtual representation of the blank, positioning of the virtually represented dental restoration in the virtually represented blank taking into account the material characteristics of the layers and/or regions, determination of the data for the blank which correspond to the position of the virtually arranged dental restoration or the mold in the blank, as well as transfer of the data to a machine to produce the dental restoration from the blank.

The invention relates to a method for the production of blocks of material of a polymerized dental composite material as well as to the blocks of material obtainable according to the method, in which (i) a polymerisable dental composite material is transferred into a pressure-resistant casting mould (100), (ii) a pressure in the range of 10 to 500 MPa is applied to the polymerisable dental composite material in the pressure-resistant casting mould, and (iii) at least a part of the casting mould and/or the polymerisable material is heated in a defined manner to a temperature of 90 to 150 C.

The invention relates to a dental divestment method in which dental restoration parts are divested from a cured muffle by sandblasting. In the production of the muffle molded part or moldings (20) or protrusions (58) are realized in or at the casting mold by means of a casting compound (21), said molded part or moldings or protrusions consisting of a burn-out material. They are removed after curing. The indentations produced in this way are configured as predetermined breaking points for the muffle.

The present invention provides a dental mill blank having reduced cracks and that excels in mechanical strength and aesthetic quality. The present invention relates to a dental mill blank comprising an inorganic filler and a polymer, and having a porosity of 25 to 35 volume % after 2-hour ashing at 600 C. In the dental mill blank, the inorganic filler preferably comprises an inorganic filler (A) and an inorganic filler (B), and the dental mill blank preferably satisfies the following formulae (I) and (II),

0.12a0.70(I)

3b/a(II),

where a is an average primary particle diameter of the inorganic filler (A) in micrometers, and b is an average primary particle diameter of the inorganic filler (B) in micrometers. Preferably, the inorganic filler (A) and the inorganic filler (B) have a volume-to-volume content ratio (A)/(B) of 5/95 to 50/50.

Methods for manufacturing anatomical healing caps, including forming an anatomical healing cuff body for a given tooth position, the anatomical healing cuff body having a cross-section and an exterior surface so that the anatomical healing cuff body provides substantially custom filling of at least an emergence portion of a void where a natural tooth once emerged from the void or where a tooth would have emerged from a void of the given tooth position, and forming both lateral buccal and lingual handle extensions extending from the anatomical healing cuff body so that the manufactured anatomical healing cap includes a laterally extending buccal handle extension and an oppositely disposed laterally extending lingual handle extension, the buccal and lingual handle extensions being integrally formed with the healing cuff body. The healing caps can be formed using a casting jig, by machining, by 3D printing, or other suitable methods.

Methods and dental prosthetics for providing soft tissue adhesion to a temporary healing abutment, or other dental prosthetic (e.g., temporary or permanent). Existing prosthetics generally do not provide any significant adhesion of the soft tissue surrounding the prosthetic, to the outer surface of the prosthetic itself. Because of the presence of gaps between such structures, or simple non-adhesion even where the structures may touch (but be free and unattached relative to one another), there is a tendency for pathogenic microbes to enter into such space between the structures, and for the soft gingival tissue to recede, particularly in patients with thin type periodontal tissue. The present disclosure provides materials and/or surface treatment (e.g., texturing) that ensures good bonding between the prosthetic and the soft tissue, reducing risk of infection, and reducing undesirable gingival recession surrounding the prosthetic anchored on a dental implant.

A method of taking a scan of a patient's oral cavity may include providing an anatomical healing cap that can be received within a subgingival void of a given tooth position. The method may also include taking a first scan (e.g., an extraoral scan) of the anatomical healing cap before seating the anatomical healing cap into the subgingival void of the given tooth position, where the anatomical healing cap is coupled to an implant disposed adjacent the anatomical healing cap. Further, the method can involve taking a second scan (e.g., an intraoral scan) of the anatomical healing cap and surrounding surfaces, and then integrating the two scans into an overall oral cavity scan. Reference points from the first scan may be used to align the second scan with the first scan, integrating the two together.

Dental implants including radiopaque markers provided therein or thereon. The implant may also include customizable length characteristics. For example, a kit may include implants with different diameters (e.g., 3 diameters), where all of the implants are of a single (e.g., long) length. The appropriate diameter implant may be selected from the kit by the practitioner, and the long length implant may be cut (e.g., with a dental drill) to the appropriate length needed. The implants include radiopaque markers on or within the implant. For example, three series of markers may be provided on different faces of the implant, so that the three series of markers serve as reference points when scanning, allowing triangulation of the exact position of the implant in relation to the surrounding hard and soft oral tissues.
