    摘要： A dental machining system for manufacturing a dental restoration, including: a dental tool machine which includes: a dental blank holder for holding one or more dental blanks relatively movable with respect to one or more dental tools; one or more driving units each for movably holding at least one dental tool for machining the dental blanks; a determination unit for determining the type of each dental blank; an adjustment device for allowing the user to adjust the machining time, a level of quality of the dental restoration, and a level of security of the dental restoration and dental tool against machining damage. The system further includes a control unit which executes a trained artificial intelligence algorithm adapted to generate process parameters for the machining.

    摘要： Flow-driven dental instrument (1), comprising a grip part (2), a head part (3), a media line (4), and a fastening means (8), wherein the grip part (2) is constructed in the form of a sleeve with two ends and a media connection (5) is disposed on the first end. At the second end, the head part (3) projects at least partially into the grip part (2). A first end of the media line (4) is connected to the head part (3) and the media line (4) extends from the head part (3) through the grip part (2) to the media connection (5). The fastening means (8) comprises a sleeve (9) having an external thread and a nut (10) having an internal thread, wherein the sleeve (9) is connected to the outer wall of the media line (4) in a material-locking manner and, at least in a direction toward the head part (3), the nut is held in the grip part (2) in a fixed position.

    摘要： Described herein are dental treatment compositions, more particularly, a dental varnish composition useful in effective fluoridation, enhancement of remineralization the tooth enamel, and hypersensitivity through occlusion of dentine tubule. The dental varnish composition includes a hydrogel system and at least one fluoride source, wherein the dental varnish is water soluble. The hydrogel system includes at least one polyphenol having at least one phenol group, at least one polymer, and a metal ion. Described herein are also methods of making dental varnish composition in a single step and one pot synthesis.

    摘要： The present invention is related to a dental composition comprising: (a) at least one polymerizable monomer having at least one ethylenically unsaturated group; (b) a radical initiator system comprising (i) a photosensitizer having an absorption maximum ranging from 400 nm to 800 nm; (ii) a coinitiator; and (iii) a compound of the following formula (1): wherein R1 and R2, which may be the same or different, independently represent a hydrogen atom, a C1-6 alkyl group, or a C1-6 alkoxy group; R3 and R4, which may be the same or different, independently represent a hydrogen atom, or a C1-6 alkyl group, or R3 and R4 may represent a bond so that the carbon atoms to which R3 and R4 are bonded are linked by a double bond; R5 and R6, which may be the same or different, independently represent a hydrogen atom, or a C1-6 alkyl group, or R5 and R6 may represent a bond so that the carbon atoms to which R5 and R6 are bonded are linked by a double bond; L represents a single bond or a group —CRH—, wherein R may be a hydrogen atom, a C1-6 alkyl group, or a C1-6 alkoxy group; n and m, independently are integers of 1 to 6.
