摘要： A mill blank assembly for a dental prosthesis includes a milling section and a support section for supporting the assembly in a milling machine. In certain embodiments, the milling section is adhesively bonded to the support section by a direct chemical bond that provides enhanced resistance to unintentional detachment of the milling section from the support section during a subsequent machining operation. Optionally, the support section includes a passageway that receives a quantity of flowable dental restorative material used to make the milling section, such that the restorative material that is located in the passageway provides additional resistance when hardened to unintentional detachment of the milling section from the support section.

摘要： The present invention provides a tough denture and a method for producing the denture, which includes solid PMMA as a main component, being added to polar elastomer selected from a group of polyacrylate rubber copolymer, methylmethacrylate-alkylacrylate-styrene terpolymer, and fluororubber, and is fabricated in a process of being mixed and injected into a denture mold. A PMMA denture of present invention shows improved safety to living organisms and increased productivity of molding because of excellent mechanical properties and remarkable elution volume decrease after polymerization in comparison with ordinary type dentures of heat-polymerized PMMA. Furthermore, it is possible to widely apply the denture clinically because of good adaptability in oral applications with economical advantages.

摘要： Dental composition, product and process using a silicon containing abrasion resistant material. The dental products formed are abrasion resistant and self-lubricating across their entire cross sections. Dental compositions useful for forming dental products in accordance with the invention preferably includes an ethylenically unsaturated silane. The composition is formed into a dental prosthesis, such as an artificial tooth, inlay, onlay, facing, crown or bridge.
