The invention concerns a dental restoration composition which consists of a mixture in the form of a liquid paste which comprises a polymerizable resin mixture containing one or a plurality of polymerizable acids, a filler mixture and a light-hardening starter system. The invention further concerns a method of introducing this composition directly into the dental cavity using a suitable application instrument with a thin canula and hardening the composition in the tooth by exposure to light. | ||||||
243 | Radiopaque dental composites | EP98114735.8 | 1998-08-05 | EP0895774A2 | 1999-02-10 | Schulman, Martin; Prasad, Arun |
A fiber-reinforced composite material fro dental restorations, wherein the reinforcing glass fibers comprise a radiopacity-imparting agent, and are therefore inherently radiopaque. Preferably, the glass fibers comprise tantalum oxide, in an amount from about 5 to 60 percent by weight of the total glass composition and most preferably from about 10 to about 25 percent by weight of the total glass composition. The radiopaque fiber-reinforced composite is particularly useful as a structural component for bridges or a tooth restoration after endodontic treatment. |

Date Jul. 22, 1993A prefabricated inlay (1) for restoring a tooth by application and fixation in a cavity prepared in the tooth and having essentially the same shape as the inlay part adapted for insertion, is provided with a pin (6) which projects from the inlay part not adapted for insertion and which is arranged to be received in an inlay holder. The whole inlay (1) is made of a material translucent to light that is suitable for curing a light-curing material used for fixing the inlay in the cavity. The inlay holder has a light source and a light guide having a tip (18) with a recess (19) for receiving the pin (6) of the inlay (1), such that the light generated by the light source can be guided through the light guide and the inlay (1) to the light-curing material. A tooth restoration set comprises a plurality of prefabricated frustoconical inlays (1), preferably having the same cone angle as well as several different narrow-end diameters, and a plurality of frustoconical burrs having the same cone angle as the inlays (1) as well as corresponding different narrow-end diameters. | ||||||

A method of polymerizing a photo-polymerizable dental composition with the use of a light-curing apparatus including a light source (1) for emitting a laser beam and an optical fiber (2) optically coupled with the light source (1) and having a light emitting element (5) opposite to the light source (1). The photo-polymerizable dental composition (M) is filled in a dental cavity (H), and the light emitting element (5) of the optical fiber (2) is subsequently introduced in the filled photo-polymerizable dental composition (M) to a position adjacent a bottom of the dental cavity (H). Thereafter, the filled photo-polymerizable dental composition (M) is irradiated with the laser beam of 350 to 500 nm in wavelength at 10 to 100 mW, to cause the filled photo-polymerizable dental composite (M) to initiate polymerization progressively from a portion thereof adjacent the bottom of the dental cavity (H) towards a surface portion thereof. |

The cavity and each porcelain chip (9) are subjected to necessary etching, silanization, and application of a binder before implantation occurs. At first, a moulding (10a) is made of the cavity (2, 3, 4), whereupon the moulding (10a) is fastened to the porcelain chip (9). Then the porcelain chip is contour worked to substantially the same shape as the moulding (10a), and the formed chip (9c) is placed in the cavity and fastened by means of a binder to the original tooth (1). | ||||||
248 | Artificial tooth veneer restorations | EP91850218.8 | 1991-09-09 | EP0477157B1 | 1996-01-03 | Odén, Agneta; Andersson, Matts |
The present invention relates to a method of manufacturing artificial tooth veneer restorations for natural teeth composed of a ceramic core (B) by pressing and sintering ceramic powder. The core (B) is preferably manufactured from a high strength densely sintered ceramic material by copy milling from an impression of the prepared tooth surface (P) to a compacted body, a presintered body or a sintered body. Alternatively the core (B) is manufactured by compacting the ceramic powder against a body, which surface is copy milled from a modell of the prepared tooth surface (P). During the copy milling the sintering shrinkage is considered by enlargement of the copy milled compacted body, the presintered body or the sintered body corresponding to the sintering shrinkage. The tooth veneer restorations are given their final shape by shaping the external surface (Y) of the compacted, presintered or sintered ceramic body. After the final sintering the external surface (Y) can be shaped before a veneer material is attached to the external surface of the core (B) by firing of dental porcelain (A). Manufacturing ceramic teeth veneer restorations according to the method of this invention increases their strength and accuracy to shape. |

249 | DENTAL TREATMENT SYSTEM. | EP93908651 | 1993-03-26 | EP0634914A4 | 1995-08-30 | GALLANT BEN J |
A system of treating teeth or associated tooth structure uses an abrasive-laden fluid. Fluid (101) at different selected pressures (103) is delivered to a device (105) for mixing the fluid with abrasive. The air/abrasive mix flows through a hand-held device (107) to the point of treatment. A selective control (107, 191) delivers air or air and abrasive as desired. Upon termination of an air/abrasive treatment, air is diverted through a purge line (214) to purge the system downstream from the abrasive device. A vacuum (221) removes abrasive and debris from the patient's mouth during and after the abrasive treatment. A hand-held nozzle device (107) has finger controlled fluid ports (194-197). A disposable collection chamber (232) for sterile disposal of the abrasive and debris has a common filter (233) for the purge circuit and the system for removal of abrasive and debris from the mouth. The existing dental office suction system or venturi may provide suction for the vacuum. Pressure regulating and relief valves insure instantaneous change from one pressure to another. | ||||||

L'invention se rapporte à l'application d'un ciment humide à l'ionomère de verre sur une lésion dentaire. Avant que le ciment ne durcisse, on applique l'amalgame humide sur le ciment à l'ionomère de verre. L'ionomère de verre se fixe à la dent, et l'interface du ciment humide et de l'amalgame humide permet de créer de fortes liaisons entre le ciment à l'ionomère de verre et l'amalgame, pour assurer une liaison extrêmement forte entre l'amalgame et la dent. Des bases métalliques, des sels métalliques et/ou des oxydes métalliques sont ajoutés à une formule d'amalgame de reconstitution s'utilisant en conjonction avec un ciment à l'ionomère de verre pour réparer une lésion dentaire. L'additif se compose d'une quantité suffisante de bases métalliques, de sels métalliques et/ou d'oxydes métalliques, tels que de la poudre d'un ciment dentaire au polycarboxylate, pour améliorer la force de liaison entre le ciment humide à l'ionomère de verre appliqué à la dent et l'amalgame humide amélioré appliqué au ciment humide. En conséquence, la durabilité d'une telle reconstitution est améliorée et peut ainsi permettre d'obturer une lésion avec un amalgame plutôt que de nécessiter l'extraction de la dent ou l'application d'une prothèse. | ||||||
