Area of Science:

  • Restorative Dentistry
  • Biomaterials Engineering
  • Digital Manufacturing

Background:

  • Computer-assisted design (CAD) and computer-assisted machining (CAM) are crucial for modern dental restorations.
  • Current systems must meet and exceed existing standards for material and clinical quality.
  • Polyvalent processing capabilities are essential for system development.

Purpose of the Study:

  • To evaluate the Precident system for computer-assisted manufacturing in restorative dentistry.
  • To assess its capabilities in producing high-quality dental prosthetics.
  • To determine its clinical and economic viability.

Main Methods:

  • Utilized an improved CCD chip scanner for automated cast scanning.
  • Employed a numeric control (NC) machine capable of processing diverse materials.

  • Routinely applied the system for single crowns and fixed prosthetic devices (FPDs) up to four units.

    • Main Results:

    • The Precident system demonstrated improved scanner resolution and automated casting scanning.
    • It facilitates the production of frameworks for fixed prosthetic devices (FPDs) and removable prosthetic devices (RPDs).
    • The system's polyvalence allows processing of metal alloys, ceramics, and fiber-reinforced resins.

    Conclusions:

    • The Precident system is a clinically proven and competitive CAD/CAM solution for dental restorations.
    • It meets high standards for material and clinical quality.
    • CAD/CAM all-ceramic restorations produced by the system are cost-competitive with traditional methods.
