What are the Workflow Steps in Chair-Side Digital Manufacturing?

Oral dental CAD/CAM digital manufacturing follows a simple process that greatly reduces patient waiting time compared to traditional methods using CAD/CAM digital technology and equipment. Steps usually include:

1. Patient consultation, taking oral X-rays, doctor-patient communication to determine the treatment plan.

2. Tooth preparation: The dentist removes all decayed material, prepares the patient's teeth for scanning and restoration, and cuts and shapes the patient's teeth appropriately to create a surface suitable for placing restorations (e.g., crowns, bridges, inlays, etc.)

Color Comparison: The color of the restoration is compared to the color of the teeth in the patient's mouth to determine the color shade of the restoration

3. Scanning: The dentist uses a handheld intraoral scanner to capture a three-dimensional image of the patient's teeth and mouth.

4. Design: The dental technician imports the 3D scan data into CAD design software and creates a 3D model of the restoration.

5. Cutting：Using the denture cutting equipment (dry/wet engraving and milling machine), the denture material (such as metal, resin, zirconia all-ceramic, etc.) is precisely cut and shaped to achieve the shape and size required by the design. This process is a very critical step in denture making, which directly affects the comfort, function and aesthetics of the denture.

6. Trial wear: give patients a preliminary trial wear, check the shape, bite and comfort, if found inappropriate places, need to be adjusted and refined.

7. High-temperature crystallization: after high-temperature crystallization sintering, the crown becomes harder and the surface color is closer to the color of natural teeth.

8. Glaze: technicians have been polished for the crown staining glaze, and need to be put into the porcelain oven for baking, in order to fix the enamel layer and enhance the strength and durability of the denture, so that the denture as a whole is closer to the patient's own teeth appearance, to avoid the situation of false white.

9. Wearing teeth: the dentist will be installed in the patient's mouth, cleaning and disinfection of the restorations, and the use of adhesives for permanent fixation.

Overall, CAD/CAM digital fabrication technology not only improves patient comfort and satisfaction, but also increases the efficiency of dental offices and laboratories, providing patients with faster and better results.
