Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM)

Dental CAD-CAM systems have advantages that cannot be matched with respect to the strength of materials and precision of the restorations. Dental materials used here are manufactured using standardized manufacturing procedures under strict quality control. These materials are generally better in quality, strength, and durability than those used to make dental restorations in the traditional casting process. Furthermore, due to the computer-controlled milling process, the materials are not subjected to human error that can lead to problems. Therefore, dental restorations fabricated from CAD-CAM systems possess optimum strength (all-ceramic materials have a flexural strength > 500 MPa). In terms of restorations precision, because of the accuracy of the scanner, software, and milling machine in a CAD-CAM system, the fit of the dental restorations is quite predictable.

CAD-CAM is the acronym for computer-aided design and computer-aided manufacturing, it offers high precision and high-quality restorations. The whole process involves 3D designing and imaging of the teeth using computer software. Once the restoration is designed by the computer under the direction of a dentist, the information is sent to a sculpting machine which creates the restoration to exact specification. The precision and fit of such crowns are much superior to manually built-up crowns.

Why Dr. Motiwala International dental implant center use CAD-CAM systems to fabricate dental restorations?

German Technology

Dr. Motiwala International dental implant center is in pace with current technology and ever-rising industry standards. CAD/CAMs are the latest dental innovations that give a micron level accuracy in the fit of the dental prosthesis. This provides a much stable crown fit and occlusion thus avoiding revisits to the clinic once the treatment is complete. Hence these latest advancements provide great comfort to our patients.

Our CAD/CAM systems consist of three components:

  1. Computerized Surface Digitization Using Scanners.

Geometry is transformed into digital data which can be processed by a computer. The data acquisition involves making an optical impression of the preparation.

  1. CAD

Data is obtained from the scanning process and, depending on the application, a data set is produced to fabricate the product. We can store the data of the construction in various data formats, but the standard is often STL files.

With CAD software, we can provide various dental restoration designs to the CAM unit.

  1. CAM

A production technology that transforms the data set into the desired product through milling. We can differentiate the processing devices according to:

  • Dry or Wet Milling
    • Dry Processing: This can be applied to zirconium oxide blanks with a low degree of pre-sintering.
    • Wet Processing: A spray of cool liquid protects the milling diamond or carbide cutter to avoid damage due to the heat. This process is necessary for metals and glass-ceramic.
  • Number of Milling Axes
    • 3-axis: This milling device has degrees of movement in the three spatial directions.
    • 4-axis: This device includes the tension bridge rotations as the fourth axis of movement.
    • 5-axis: The fifth axis is rotating the milling spindle.
