The CEREC CAD-CAM system enables same-day ceramic restorations without impressions or lab work. This advanced technology streamlines dental procedures for efficient, single-appointment treatment.

Area of Science:

  • Dentistry
  • Biomaterials Engineering
  • Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM)

Background:

  • Traditional dental restorations often require multiple appointments, impressions, and laboratory fabrication.
  • The integration of digital technology aims to improve efficiency and patient experience in restorative dentistry.

Purpose of the Study:

  • To describe the Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) CEREC system for fabricating ceramic restorations.
  • To outline the workflow and capabilities of the CEREC system for single-appointment dental procedures.

Main Methods:

  • Stereo-photogrammetric scanning of cavity preparations using a 3D miniature video camera.
  • Electronic design of the restoration on a video display, with microprocessor-assisted 3D model generation.

  • Numerical transfer of digital data to a miniature three-axis milling device for ceramic block fabrication.

    • Main Results:

    • The CEREC system allows for the complete fabrication of ceramic restorations within a single dental appointment.
    • The process eliminates the need for traditional impressions and external laboratory assistance.
    • Restorations are milled from a standard ceramic block with precision fitting in approximately 10-15 minutes.

    Conclusions:

    • The CAD-CAM CEREC system offers a streamlined, efficient approach to ceramic dental restorations.
    • This technology significantly reduces treatment time and enhances patient convenience by enabling same-day restorations.
