Abstract: A dental veneer made from a composite comprising at least one organic binder, preferably with methacrylate, and inorganic solid particles as fillers. Methods for manufacturing the dental veneer include curing the composite with heat and light under pressure followed by laser treating the facial surface of the veneer to form a smoother facial surface. Filler particles at the facial surface of the veneer can be melted and/or coalesced together to form a continuous glass surface, which is more natural looking and better resembles natural tooth material as compared to ceramic veneers or other composited veneers lacking surface treatment.

Abstract: A method for producing partial dental prosthesis having at least one surface for forming a chewing surface of a posterior tooth is provided. The method includes (i) providing a composite material with at least one organic binding agent and solid particles that consist of glass as filler; and (ii) applying a laser to at least some regions of a surface of the chewing surface such that the at least one organic binding agent is burnt off in laser-treated regions and the solid particles are melted and fused together to form a continuous enamel layer.

Abstract: An endodontic pin (1) having a base (2), wherein the base (2) has a root portion (3) for fastening the base (2) in a natural tooth root (4) and a crown portion (5) for fastening a dental crown facing (6) to the endodontic pin (1) and/or for arrangement in a natural tooth crown (32). The base (2) is formed of a composite material (7) which includes at least one organic binder (8), the composite material (7) including glass particles (9) as a filler.

Abstract: A partial dental prosthesis (1) having at least one surface (2) for forming a chewing surface of a posterior tooth (3), wherein the partial dental prosthesis (1) includes a composite material (4) and the composite material (4) contains at least one organic binding agent (5), preferably methacrylate, and, preferably inorganic solid particles (6) as filler, wherein at least the surface (2) for forming the chewing surface, preferably the entire outwardly facing surface, of the partial dental prosthesis (1), is formed at least in some regions, preferably completely, by a layer (7) that includes fused-together solids particles (6).

Abstract: A polymeric material is curable from an uncured state to a cured state and includes at least one finely dispersed filler. The material has in the cured state, a translucency in the range of about 30% to about 100%, and shore A hardness according to DIN 53505:1984 in the range of about 20 to about 70 and a tensile strength according to DIN 53504:1994 in the range of about 1.5 MPa to about 4.5 MPa. The material has in the uncured state, a consistency according to DIN ISO 4823:2000 of type 0 to 3.

Abstract: The present invention is related to clear crosslinkable polymeric masses for the registration of fingerprints, allowing to obtain positive reproductions of fingerprints by taking a photograph through a clear cured layer obtained from said polymeric masses.

Abstract: The invention relates to a process of retraction of sulcus, comprising the steps of: applying a silicone material onto and/or at the vicinity of the boundary of a tooth and adjacent sulcus, which silicone material expands during or after its curing reaction; applying a cap onto said tooth, thereby forming a chamber over said silicone material, wherein said chamber comprises as its walls the tooth, the cap and an outer section of said sulcus; whereby said chamber allows for the silicone material to expand into the crevice between sulcus and tooth. Said cap is at least partially filled with a plastically deformable material when applied onto said tooth in step; and/or said cap is deformable, especially under biting pressure.

Abstract: Sulcus is retracted from teeth prior to performing a dental procedure on the teeth by applying an expandable curable silicone compound to the surface of the teeth and preventing the silicone compound from expanding in a direction away from the surface of the teeth, thereby forcing the silicone to expand against the sulcus and forcing retraction of the sulcus from contact with the teeth.

Abstract: The invention relates to a retraction thread, especially a dental retraction thread for use in dentistry, that is distinguished by the fact that it has yarns produced by an air vortex process.

Abstract: The invention relates to a method of dental impression taking, comprising the step of applying a polymeric material at least partially to the region to be reproduced by the impression, wherein the polymeric material is translucent, and accordingly suitable polymeric materials.

Abstract: Sulcus is retracted from teeth prior to perfroming a dental procedure on the teeth by applying an expandible curable silicone compound to the surface of the teeth and preventing the silicone compound from exanding in a direction away from the suface of the teeth, thereby forcing the silicone to expand against the sulcus and forcing retraction of the sulcus from contact with the teeth.
