Abstract:
The invention includes a support frame for producing a dental workpiece. The frame has a Z axis and comprising wall sections defining a hole that extends along the Z axis through the frame. At least one of the wall sections comprises an adhesive-directing surface extending along the Z axis in a non-parallel relationship. Such a configuration provides optimized methods for affixing a blank to the support frame and optimized properties of the blank after fixation to the support frame.
Abstract:
A system and method for making a layered dental appliance. The system can include a first portion comprising a negative of a first layer of a layered dental appliance, and a second portion comprising a positive shape of a second layer of the layered dental appliance. The method can include providing a mold comprising a negative of an outer shape of a layered dental appliance, and positioning a slurry in the mold, forming a first layer of the layered dental appliance. The method can further include providing a solid structure comprising a positive shape of a second layer of the layered dental appliance, and pressing the solid structure into the slurry in the mold.
Abstract:
The invention relates to a method of making a dental blank which combines uniaxial pressing isostatic pressing techniques. The invention also includes a press for performing the method and a system comprising a uniaxial and a isostatic press. The invention may help in efficient manufacturing of dental blanks at minimized costs and maximized quality.
