HEATING ELEMENT FOR A FURNACE FOR FIRING OR SINTERING WORKPIECES, AND FURNACE HAVING AT LEAST ONE SUCH HEATING ELEMENT
The invention relates to a heating element (7) for a furnace, which heating element comprises a sapphire glass tube (8) for receiving a heating coil (17) inside the sapphire glass tube (8). The sapphire glass tube (8) is gas-tightly connected to a borosilicate tube (14) and also to a quartz glass tube (15). The electrical connections at the ends lead through in a gas-tightly compressed manner. According to the invention, the tube element is made of sapphire (8) and is gas-tightly joined by transition glasses and glass solder to compensate for the different coefficients of thermal expansion. The joined elements (14, 15) are located outside the firing chamber (2) so that they ensure operational reliability in the case of a thermal effect of up to 500°C. Furthermore, for firing/sintering the ceramic element (4) with shortwave infrared radiation in the range of from 0.8 µm to 2.5 µm, the heating element (7) has stable optical, electrical and mechanical properties and thus high-quality, permanently uniform firing and sintering results are ensured with significantly shortened firing-sintering times. No changes to the surface of the heating elements (7) occur which are caused by chemical influences or evaporations from the fired-sintered elements. No contamination of the sintered objects and the firing chamber occurs which is caused by the heating element (7). The heating element (7) can be used at an operating temperature up to 1900°C and thus ensures use over long uptimes.

Abstract
Artificial teeth are inserted in a denture base in order to produce a denture. The artificial teeth used according to the invention have an outer part, which is visible in the inserted state. An inner part is arranged in the denture base in the inserted state. A virtual data record of the artificial tooth, which corresponds to the outer side of the tooth, helps to define a virtual gum line in a region of the inner part of the tooth, which is undercut-free. In order to produce a denture base, cavities are created in the denture base. In order to be able to create the cavities with the help of automatic production methods such as CAD/CAM methods, the artificial teeth are virtually subtracted from a virtual denture base such that a cavity edge is defined, which corresponds to the virtual gum line.
A retaining device for dental prosthesis elements (14) comprises an implant (10) and an intermediate element (12). The implant (10) is hold in place in a jaw bone (22) preferably by screwing. The one-part implant (10) has an implant shaft (16), an implant head (25) and a shoulder (26). The implant shaft (16) projects over the jaw bone (22) into the gums (42). An intermediate element (12) is connected to the shoulder (26). Said intermediate element (12) is located substantially within the gums and serves to accommodate a dental prosthesis element (14).

A preform intended for the production of a dental prosthesis. The preform includes a group of agglomerated ceramic, glass-ceramic or glass particles, such that, as volume percents: more than 40% and less than 90% of the particles of said group have a size greater than 0.5 μm and less than 3.5 μm, said particles hereinafter being denoted “enamel particles”, and more than 10% and less than 60% of the particles of said group have a size greater than 3.5 μm and less than 5.5 μm, said particles hereinafter being denoted “dentine particles.” The microstructure of the preform is such that there is an axis X, termed “axis of variation”, along which the Ve/(Ve+Vd) ratio changes continuously, Ve and Vd denoting the volume percents of enamel particles and of dentine particles, respectively. The enamel and dentine particles representing, together, more than 90% of the volume of the agglomerated particles.

Artificial teeth are inserted in a denture base in order to produce a denture. The artificial teeth used according to the invention have an outer part (12), which is visible in the inserted state. An inner part (14) is arranged in the denture base (20) in the inserted state. A virtual data record of the artificial tooth, which corresponds to the outer side of the tooth, helps to define a virtual gum line in a region of the inner part of the tooth, which is undercut-free. In order to produce a denture base, cavities (22) are created in the denture base. In order to be able to create the cavities (22) with the help of automatic production methods such as CAD/CAM methods, the artificial teeth are virtually subtracted from a virtual denture base (20) such that a cavity edge (24) is defined, which corresponds to the virtual gum line (10).

Abstract
The invention relates to glass-ceramics based on the lithium disilicate system which can be mechanically machined easily in an intermediate step of crystallization and, after complete crystallization, represent a very strong, highly-translucent and chemically-stable glass-ceramic. Likewise, the invention relates to a method for the production of these glass-ceramics. The glass-ceramics according to the invention are used as dental material.

ARTIFICIAL TOOTH AND METHOD FOR PRODUCING A DENTURE BASE
Artificial teeth are inserted into a denture base for producing a denture. The artificial teeth used according to the invention have an outer part (12), which is visible in the inserted state. An inner part (14) is arranged within the denture base (20) in the inserted state. According to the invention, a tooth edge (10) with a change of angle is embodied between the outer part (12) and the inner part (14). For producing a denture base, cavities (22) are generated in the denture base. In order to be able to produce the cavities (22) with the aid of automated production methods such as CAD/CAM methods, there is a virtual subtraction of the artificial teeth from a virtual denture base (20). As a result of this, a cavity edge (24) which corresponds to the tooth edge (10) is generated. The cavity edge (24) is used during the production of the cavity (22) by a CAD/CAM method for setting the tool movement.
