Area of Science:

  • Biomedical Engineering
  • Dental Technology
  • Metrology

Context:

  • Accurate measurement of occlusal surfaces is crucial for dental restorations.
  • Existing methods for dental cast digitization can be time-consuming and less precise.

Purpose:

  • To introduce a new laser-based system for high-accuracy surface morphology measurement of occlusal materials.
  • To enable rapid and detailed digitization of dental casts.

Summary:

  • A novel system uses a flat laser beam to measure occlusal material surface morphology with high accuracy.
  • It digitizes 200 points simultaneously over a 30 mm line, capturing the entire dental cast morphology in 8-10 minutes.
  • A central processing unit reconstructs and displays the numerical data of the dental morphology.
