20080206704 | Dental modeling system with drillable tray base - A dental articulating system and method configured to duplicate at least a portion of a patient's mouth for use in producing a dental prosthesis securing an impression tray to a flexible and resilient material on a stabilizing plate of an alignment fixture. The position of the impression tray is adjusted on the flexible and resilient material. A tray base is detachably secured to a bottom of the alignment fixture. The tray base with the alignment fixture thereon is placed on a drilling fixture. A drill bit is aligned with a location of an impression corresponding to a prepped tooth of the impression tray. A hole is drilled in the tray base corresponding to the prepped tooth. | 08-28-2008 |
20090081615 | METHOD OF REGISTERING A DENTAL MODEL ON A TRAY BASE - A method for registering a dental model on a tray base includes obtaining a dental model that is an impression of at least some of a patient's teeth; disposing the dental model on a tray base; drilling at least one registration pin hole from a bottom of the tray base, through the tray base, and into a bottom of the dental model while the dental model is disposed on the tray base; and inserting at least one registration pin into the at least one registration pin hole with the at least one registration pin extendable between the dental model and the tray base. | 03-26-2009 |
20090274994 | Device and Method of Securing Dental Material for Production of Dental Prosthesis - A system and method for milling dental prostheses in a CNC milling machine includes a larger millable dental blank receivable in a primary fixture of a milling machine and capable of being machined to form one or more dental prostheses; a plurality of smaller millable dental blanks each capable of being machined to form a dental prosthesis; and lateral affixing means for affixing a lateral side of the plurality of smaller millable dental blanks in a space defined by the larger millable dental blank in the primary fixture, when the larger millable dental blank is removed. | 11-05-2009 |
20090275000 | System and Method for Securing Multiple Ceramic Dental Blocks for Milling - A system and method for milling dental prostheses in a CNC milling includes affixing a lateral side of each of a plurality of ceramic millable dental blanks to a lateral wall of a fixture; securing the fixture to a chuck of the milling machine; wet milling a single dental prosthesis in each of the plurality of ceramic millable dental blanks with a diamond burred cutter; and removing the plurality of ceramic millable dental blanks from the fixture. | 11-05-2009 |
20120148985 | Method for Machining a Dental Prosthesis - A method for machining a dental prosthesis that reduces the likelihood of forming tool failure includes machining a workpiece to form a top surface and a side surface of the dental prosthesis, machining a connector between a proximal end of the dental prosthesis and a proximal end of the workpiece, and machining a bottom surface of the dental prosthesis with a spiral tool path. | 06-14-2012 |
20120177456 | METHOD FOR MACHINING A DENTAL PROSTHESIS - A method for machining a dental prosthesis that reduces the likelihood of forming tool failure includes machining a workpiece to form a bottom surface without machining a bottom cavity of the dental prosthesis, then machining the bottom cavity and machining the top. | 07-12-2012 |
20120214133 | METHOD FOR FABRICATING A CUSTOM IMPLANT ABUTMENT - A system and method for fabricating custom implant abutments uses an implant abutment connector to secure a partial blank with respect to a milling tool of a CNC milling machine. The implant abutment connector has an implant interface geometry of an implant. The partial blank can have a prefabricated implant abutment interface geometry of the implant abutment; and can thus mate with the implant, and the implant interface geometry of the implant abutment connector. | 08-23-2012 |
20130221554 | Non-Pre-Colored Multi-Layer Zirconia Dental Blank that has a Gradual Change in Translucency through a Thickness After Sintering - A dental block for producing a dental prosthesis comprises a green body including zirconia and having a chemical composition including increasing amounts of yttria through a thickness of the green body. The green body is substantially opaque with a substantially consistent optical characteristic of non-translucency with respect to visible light across the thickness, and is subsequently millable and sinterable to form the dental prosthesis with an optical characteristic of increasing translucency through a thickness of the dental prosthesis. | 08-29-2013 |
20140205968 | Sleeve for Cutting Bur for Dental Cutting Guide - A dental cutting system for cutting a patient's tooth comprises a cutting guide with a slot to guide a cutting tool. Opposing channels are formed in opposing walls of the slot. A sleeve is slidably disposed in the slot and has an enlarged collar slidably disposed in the opposing channels. The enlarged collar retains the sleeve in the slot with respect to an in-and-out direction and limits the sleeve to movement within and along the slot. The sleeve has a bore removably receiving the cutting tool, with the cutting tool being rotatable in the bore and slidable through the bore in the in-and-out direction, and into and out of the sleeve. The cutting tool has two transverse degrees of freedom, including laterally along the slot, and in and out of the slot and the sleeve. | 07-24-2014 |
