Summary

This study shows that extracted human teeth can be recycled into well-fitting dental restorations using copy-milling technology. The CELAY system successfully produced accurate natural inlays with proper enamel and dentine layers.

Area of Science:

  • Dental Materials Science
  • Biomaterials Engineering
  • Restorative Dentistry

Context:

  • Advancements in copy-milling technology enable the use of natural tooth substance for dental restorations.
  • The feasibility of utilizing extracted human teeth as a source material for fabricating dental inlays requires investigation.

Purpose:

  • To determine if a copy-milling machine can produce a well-fitting Class II inlay from an extracted human tooth.
  • To verify that the milled inlay retains enamel on its outer surface and dentine on its inner surface.

Summary:

  • MO inlay preparations were made in 'host' teeth, which were then restored with 'natural inlays' milled from matched 'donor' teeth using the CELAY system.
  • Microscopic examination of sliced specimens confirmed a good fit and correct placement of enamel and dentine layers.

Related Experiment Videos

  • A secondary experiment assessed milling accuracy, revealing marginal gap performance comparable to ceramic inlays.

    • Impact:

    • This research demonstrates the successful 'recycling' of extracted teeth into accurate dental restorations using the CELAY milling machine.
    • The findings suggest a novel approach for sustainable and precise restorative dentistry.
    • The study validates the potential of natural tooth substance for creating high-fidelity dental prosthetics.
