20090321971 | Methods of Manufacturing Dental Restorations Using Nanocrystalline Materials - Dental articles are produced using relatively low sintering temperatures to achieve high density dental articles exhibiting strengths equal to and greater than about 700 MPa. Ceramic powders comprised of nanoparticulate crystallites are used to manufacture dental articles. The ceramic powders may include sintering agents, binders and other similar additives to aid in the processing of the ceramic powder into a dental article. The ceramic powders may be processed into dental articles using various methods including, but not limited to, injection molding, gel-casting, slip casting, or electroforming, hand, cad/camming and other various rapid prototyping methods. The ceramic powder may be formed into a suspension, pellet, feedstock material or a pre-sintered blank prior to forming into the dental article. | 12-31-2009 |
20100038807 | Solid Free-Form Fabrication Methods For The Production Of Dental Restorations - Solid free form fabrication techniques can be utilized indirectly to manufacture substrates, dies, models, near-net shapes, shells, and wax-ups that are then used in the manufacture of dental articles. Digital light processing is the most preferred indirect method for the production of substrates. After the substrates are produced, various coating or deposition techniques such as gel casting, slip casting, slurry casting, pressure infiltration, dipping, colloidal spray deposition or electrophoretic deposition are used to manufacture the dental article. | 02-18-2010 |
20100283168 | Systems and Methods for Setting Prosthetic Posterior Teeth in Denture Production - Systems and methods for setting posterior prosthetic teeth in production of upper and lower dentures feature tooth blocks each having inner and outer bodies having upper and lower rows of recesses therein corresponding maxillary and mandibular prosthetic teeth. The recesses of the inner and outer bodies conform to lingual and buccul surfaces of the prosthetic teeth respectively and are shaped and positioned to establish proper positioning of the prosthetic teeth relative to one another when clamped between the bodies. The two tooth blocks accommodate respective ones of left and right prosthetic poster teeth sets. Connection elements between the tooth blocks allow adjustment and subsequent locking of the relative positioning between the left and right teeth sets before setting on mandibular and maxillary casts in an articulator. The two tooth blocks eliminate the need to individually position posterior teeth on each side of the jaw. | 11-11-2010 |

20130249132 | Process and Systems for Molding Thermosetting Plastics - Process and systems for molding or forming products from thermosetting plastics. The system utilizes a deformable container that is placed within the cavity of the housing of the mold with the resins and initiator mixed therein. As a piston slides into the cavity, the upper edges of the container engage between the housing and the piston to seal the housing form leakage. The pressure of the piston along with heat on the housing enable the curing process to be controlled to minimize shrinkage and porosity. | 09-26-2013 |
20130341812 | DENTAL CERAMIC ARTICLE, PROCESS OF PRODUCTION AND USE THEREOF - The present disclosure relates to a dental ceramic article comprising ceramic components, the ceramic components having ZrO2 and Al2O3 and at least one component comprising Mn, Er or mixtures thereof, Al2O3 being present in an amount below about 0.15 wt.-% with respect to the weight of the ceramic article. The present disclosure relates also to kit of parts comprising a ceramic article and a colouring solution and processes for producing a dental ceramic article. | 12-26-2013 |
20140103557 | SHELL FORMS FOR MAKING PROVISIONAL AND LONG-TERM DENTAL RESTORATIONS - The invention provides methods of making provisional and long-term dental restorations, particularly dental veneers, implants, crowns and bridges. A shell or restoration form made of polymerizable material having good dimensional shape-stability in its uncured condition is used to make the dental restoration. A polymerizable material is introduced into the cavity of the shell form. The outer shell and injected polymerizable material are polymerized and bond together to form a hardened crown structure. In one embodiment, the restoration can be fabricated indirectly by a dental laboratory. In another version, a dental practitioner can make the restoration chairside for a patient in a dental office. | 04-17-2014 |
20140167300 | PHOTO-CURABLE RESIN COMPOSITIONS AND METHOD OF USING THE SAME IN THREE-DIMENSIONAL PRINTING FOR MANUFACTURING ARTIFICIAL TEETH AND DENTURE BASE - Photo-curable compositions for artificial teeth and denture base and a method for manufacturing denture by a three-dimensional printing system are provided.
