A palladium-based alloy having a coefficient of thermal expansion (CTE) of about 12.0 to about 13.0 and having one or more of the following additive metals: platinum, gallium, molybdenum, tin, silicon, ruthenium, rhenium, indium, tungsten, niobium, boron and lithium.

The invention relates to a scan abutment (2) for determination of the position of the plane of the front face (1.1) of a dental endosseous implant (1), wherein the abutment (2) has a longish, hollow shaft (4) and a base (3) at the bottom side (4.2) of the shaft (4), and the base (3) with at least a part of its bottom side (8.2) is attachable onto the front face (1.1) of the implant (1), wherein the base (3) has a recess (9) extending from the upper side (8.1) to the lower side (8.2) of the base (3), wherein the longish, hollow shaft (4) has from a side wall (10) having at least one through hole (5a) at its outer periphery, wherein the through hole of the side wall (10) extends from the bottom side (4.2) of the shaft (4) to the upper side (4.1) of the shaft, thereby forming a planar surface (6) in the plane (12) between shaft (4) and base (3).

A resin block that can be favorably used for obtaining dental prosthetics through the milling work, containing very little voids, having excellent property for being cut, exhibiting excellent appearance and mechanical strength, and without permitting the formation of defective products. The resin block contains a thermoplastic resin having a fluidizing temperature in a range of 310 to 500 C. and inorganic particles in an amount of 30 to 150 parts by mass per 100 parts by mass of said thermoplastic resin. The inorganic particles are at least one kind of inorganic oxide particles selected from the group consisting of silica particles, silica composite particles of silica and other metal oxides, titania particles, and titania composite particles of titania and other metal oxides. The resin block has a thick portion of a thickness of at least not less than 5 mm, and does not contain any void whose length is not less than 1.0 mm.

Addresses the invention of product comprising: metal particles and/or free or complexed metal ions; fluoride; organic acid and polysaccharides, with or without additives, designed to prevent the occurrence of tooth lesions caused by dental caries, interrupt the development of such lesions, and to promote the remineralization of the affected teeth and a process of obtaining this product.

Silver sulfadiazine-immobilized inorganic fillers are described, and their synthesis is presented. The fillers are believed to have utility in dental composites and dental adhesives to achieve potent, long-term, and none-leaching antimicrobial effects.

A tooth implant comprises a tooth body sized to correspond to a tooth to be replaced and a layer of microscopic protrusions on an outer surface thereof.

A bar of noble metal or an alloy containing noble metal having a mass mB is subdivided into nm miniature bars 2, 3 each having a specified mass mk, wherein n and m each denote an integer 2, there being an interconnection of solid material (8) between directly adjacent miniature bars (2, 3). Another bar is affixed to a backing (13), to which the miniature bars are releasably attached. A method for the production of the bar consists in dividing up the same while leaving an interconnection of solid material or producing an arrangement thereof on a backing.
