Development of Additive Manufacturing Plan for Dental Prosthesis

Problem Statement

Current dental lab industry depends heavily on worker’s skills due to too many manual operations and a traditional crowning procedure typically expects 1 week turnaround time. It is expensive, slow and difficult to meet market demand from the ageing society.

Objective

To develop an automated AM process workflow for Porcelain Fused to cobalt-chrome Metal (PFM) dental crowns with selective laser melting (SLM) to achieve lower cost and shorter turnaround time.

3D printing shortens the crown fabrication turnaround time from 16 days to 3 days
3D printing shortens the crown fabrication turnaround time from 16 days to 3 days

Key Benefits/Outcomes

  • Established CoCr coping framework printed with SLM based on 3D scanning and 3D design using ExoCAD software
  • The 3D printed crowns are expected to cost 20% less and can be ready in just 4 hours compared to traditional methods which require about 12 hours.
  • The automated AM workflow can reduce manual operations, improve the accuracy and decrease the dependence on worker’s skill.
