Definitions

  • the present invention relates to Cad/Cam (Computer Aided Design/Computer Aided Manufacturing) dental blocks of sizes C12, C14, C16 or all their sizes, for the restoration of dental pieces, specifically with the addition of slots in the block fixing system to the dental milling machine.
  • Cad/Cam Computer Aided Design/Computer Aided Manufacturing
  • the block has a metal shank for fixing to the milling machine. Once placed in the milling machine adapter, the milling process begins, which is generally only machined vertically.
  • CAD/CAM dental blocks made of lithium disilicate, feldspar, leucite ceramics, and other suitable materials are used to perform various dental restorations using computerized milling. For this, it is necessary to use blocks of different materials and dimensions; such as C12, C14, C16 blocks or all their measurements.
  • auxiliary parts include, among others: others, orthodontic retainers, buttons, clamps, tubes, brackets, springs, small fixation clamps, flexible fit modules (FFM) or flexible fit wafers (FFW) to be placed inside the mouth and attached to the teeth after custom milling of the block to fit the anatomy of a tooth/teeth and/or TADS or other orthodontic appliances such as RPE screws and/or other orthodontic hardware.
  • a new clamping system is provided perpendicular to the original clamping system and thus allows the CAD/CAM block to be rotated 90 degrees, thereby safely locating it in a dental milling machine.
  • one or more clamping slots can be added to the block. In most cases, adding only one slot will suffice to achieve proper clamping of the block in the milling machine. However, two “top and bottom” clamping slots can be added, as well as adding only one slot at the top end of the shank or only one slot at the clamping base of the block.
  • the C14 block is the most used for large volume restorations, this block measures 12 mm high, 14 mm wide and 18 mm long; however, there are many dental restorations, both tooth supported or implant supported that measure more than 12 mm high, so it is necessary to find an alternative to mill dental pieces that measure between 12 and 14 mm high, the drawback is that the traditional fixation design for CAD / CAM blocks only allows a single location in the milling system, due to the presence of 2 fixed slots in the design, limiting the possibility of milling pieces of more than 12 mm high.
  • Figure 1 is a perspective view of a C14 block, where the slots made on the block fixing system can be seen, according to the invention.
  • Figure 2 is a perspective view of the milling machine fixing system of a C14 block without modification.
  • Figure 3 is a top perspective view of the fixing system of a C14 block with only one slot added in the fixing system, according to the invention.
  • Figure 4 is a perspective view of a 13 mm dental piece already milled resting on block C14, according to the invention.
  • the representative aspects of the present description relate, in general, to certain devices, methods and systems for the production of C12, C14, C16 dental blocks or all their sizes for anatomical restorations of dental pieces.
  • the systems and methods described here are related to the systems and methods for the production of C12, C14, C16 dental blocks or all their sizes for anatomical restorations of dental pieces. of dental blocks for anatomical restorations of dental pieces in C12, C14, C16 blocks or all their measurements.
  • the description has a particular, but not necessarily exclusive, application for the production of metal fixing rods for the support and fixing of the CAD/CAM block to the receiving piece in a dental milling machine that allows a more complete machining of all the faces of a block, leaving the last milled face of the block, corresponding to the support on the block, almost completely milled, lacking the need to work this face by hand.
  • a perspective view of a C14 block (1) not yet milled can be observed, at the upper end (2) the metal fixing rod (3) can be observed, formed by a stylized cylindrical piece whose lower end (4) and upper end (5) are formed by an orthogonal cylinder joined by a cylindrical semicircular recess (6) around the axial axis (x), the upper end (2), is crowned by a 60 ° conical recess (7) oriented towards the axial axis (x) around its periphery, subsequently located on the surface of the upper end (2) two notches or grooves (8) positioned at 270 ° and (9) positioned at 0 or of the graduated circle, formed by a straight groove with its semicircular base, so as to allow securing the metal fixing rod (3) to the connector of a dental milling machine (10) (see figure 4), the base (11) of the metal rod (3) is formed by a cylindrical piece of lower height (12), with a larger diameter than the metal fixing rod (3) which is located centered with respect to the axial axis (
  • This metal rod (3) is attached to the lower end inside a prosthesis block (15) made of lithium disilicate, feldspar, ceramic with leucite, and other suitable materials, a rectangular prosthesis block (15), from which, after milling with the dental milling machine (10), the required milled dental piece (16) is obtained.
  • FIG 2 a perspective view of the upper end can be observed, comprising an upper metal stem (3) of a prosthesis (1) corresponding to a C14 block, in its original state, that is to say without the two upper and lower slots (8) and (13), nor the crown in the form of a conical recess inclined at 60° (7) towards the axial axis (x) around its periphery, a semi-circular crown (17) can be seen around the periphery of the upper end (x) and at the upper end only a slot (9) positioned at 0 o and a notch or groove (14) positioned at 0 o on the base (11).
  • FIG 3 a top perspective view of the upper end (2) of a modified C14 block with three slots of the upper metal rod (3) can be observed, where the upper notch or slot (9) positioned at 0 o and the lower slots (14) positioned at 0 o and (13) positioned at 270° located on the circular base (11) can be seen, towards the lower end the upper end of the block made of lithium disilicate, feldspar, ceramic with leucite, and other suitable materials, (15) of rectangular shape can be observed.
  • FIG 4 a perspective view of a 13 mm dental piece milled from a C14 block modified according to the invention, for the formation of a required milled dental piece (16), supported and secured in a dental milling machine (10), can be observed, it can be seen that it allows milling all the faces of the required milled dental piece (16) for its anatomical restoration.
  • the present invention finds particular use in the industry of the production of blocks to be milled used in dental restoration, CAD/CAM and precision parts, in the production of blocks for the restoration of said dental parts.

Abstract

Les blocs CAO/FAO en tailles C12, C14, C16 ou de toutes les tailles, servant à la préparation de restaurations anatomiques de pièces dentaires au moyen d'une fraiseuse dentaire, font appel à une tige métallique de fixation destinée à maintenir le bloc dentaire sur la fraiseuse. Selon cette invention, des modifications sont apportées au système de fixation, lesquelles permettent de faire tourner le bloc afin d'assurer le fraisage d'une restauration anatomique requise.
