Mixing Device and Methods For Making Bone Cement

A mixing device and methods for making bone cement. A piston (156) of the mixing device is located in a first region (158) of a chamber (112) such that a mixing paddle (154) rotates to mix bone cement components at a first pressure to make a bone cement mixture. The piston (156) is moved passed an inlet opening (136) to be located within a second region (160) of the chamber (112) to compress the bone cement mixture to a second pressure greater than the first pressure to compress the bone cement mixture and make the bone cement. The bone cement may be transferred to a delivery device. The mixing device may include features that automatically initiate the compression and transferring phases after completion of the mixing phase, and further include features that automatically terminate the operational cycle. A three-step intuitive workflow utilizing the mixing device to improve efficiency in the surgical suite is also disclosed.

PROCESS OF MANUFACTURING A DENTAL MILLING BLOCK WITH A HOMOGENEOUS COLOR AND/OR TRANSLUCENCY GRADIENT
20230270529 · 2023-08-31 ·

The invention relates to a process of manufacturing a dental milling block with a homogeneous color and/or translucency gradient. This process comprises the steps of providing a mold with a cavity having a z-direction and an x/y-direction, filling the cavity partially with a first powder up to a height H1, the first powder having a volume VP1 with a top and bottom surface, introducing a second powder on top of the first powder up to a height H2, the second powder having a volume VP2 with a top and bottom surface and, the top surface of the first powder being in contact with the bottom surface of the second powder and forming an intermediate region, providing a mixer unit with at least one rotatable mixing element, introducing the rotating mixing element in z-direction into the intermediate region, mixing the powder located in the intermediate region by rotating the mixing element, removing the rotating mixing element from the powder, compacting the powder, optionally applying heat to the compacted powder, the first powder differing from the second powder by its physical properties and/or chemical composition and/or color. The invention also relates to a process of producing a dental restoration using dental milling block obtainable according to this process.
