An integrated dental porcelain system for making dental prostheses and restorations is provided. The system includes three universal major components: a) opaque porcelain composition; b) pressable dentin ingot; and c) veneering porcelain composition that can be used interchangeably for making restorations. Techniques for making the prostheses and restorations include porcelain fused-to-metal (PFM), press-to-metal (PTM), and either pressed and/or machined all-ceramic methods. The system uses both a hand-layering of veneering porcelain (PFM technique) and a hot-pressing process (PTM and all-ceramic technique) to fabricate the prostheses and restorations.

L'invention porte sur un système de porcelaine dentaire intégré destiné à fabriquer des prothèses dentaires et des restaurations. Le système comprend trois composants majeurs universels : a) une composition de porcelaine opaque; b) un lingot de dentine pouvant être pressé; et c) une composition de porcelaine de placage qui peut être utilisée de façon interchangeable pour fabriquer des restaurations. Les techniques de fabrication des prothèses et des restaurations comprennent de la porcelaine fusionnée avec un métal (PFM), pressée sur du métal (PTM) et l'un ou l'autre des procédés tout céramique pressé et/ou usiné. Le système utilise à la fois un dépôt à la main de porcelaine de placage (technique de PMF) et un procédé de pression à chaud (PMT et technique tout céramique) pour fabriquer les prothèses et les restaurations.
