Cad-cam Milled Resin

The digital workflow links three stages: a scan captures three-dimensional geometry, design software converts that geometry into a toolpath, and a milling unit removes resin from a prefabricated block. Because each stage follows digital design data, the resulting component can reproduce planned dimensions more consistently. This connection supports patient-specific form and fit.

The prefabricated block provides a defined starting form from which the milling unit removes material. This subtractive approach allows the manufacturing system to follow a planned toolpath rather than relying on uncontrolled shaping during fabrication. Starting with standardized material supports reproducible dimensions and helps produce components that match the intended digital design.

Digital geometry determines the shape that the manufacturing system translates into a toolpath. When the scanned three-dimensional information and the planned design represent the intended patient-specific anatomy, milling can reproduce that geometry in the resin component. The resulting form can then be evaluated for fit, alongside function and overall design, before clinical use.

Production begins with a digital scan that supplies three-dimensional geometry. Software uses this information to create the component design and convert it into a toolpath. A milling unit then removes material from a prefabricated resin block under controlled conditions. After fabrication, the component can be evaluated for its form, function, and patient-specific fit.

In restorative dentistry, milled resin can support provisional crowns, bridges, and dentures. The same digital manufacturing approach can also produce surgical guides and other laboratory-fabricated medical or dental devices. These applications benefit when a custom shape, reproducible dimensions, and efficient evaluation of form or fit are important to the planned treatment or procedure.

The workflow can shorten fabrication while improving consistency between the planned design and the manufactured component. Digital data also supports efficient evaluation of form, function, and fit, which is useful when producing patient-specific restorations or prostheses. In restorative dentistry, these outcomes help laboratories and clinicians assess a component before it is incorporated into care.
