Management of erosive tooth wear using CAD/CAM

Abstract

Recent changes to CAD/CAM technology have opened new possibilities for more precise diagnosis, monitoring and treatment of Erosive Tooth Wear. Severe tooth wear is very difficult to prevent once the enamel becomes severely worn down and it makes provision of fixed prosthodontics challenging due to short clinical crown heights and lack of enamel for adhesive bonding. Our research group at King's College London have pioneered novel methods for detecting and monitoring enamel wear using high-resolution scanning, including intra-oral scanners and this is making it possible to diagnose and prevent tooth wear earlier and more successfully. Concurrently, we are one of the few centres in the world with an integrated CAD/CAM and Augmented Reality Haptic Simulation technology, which allows transferring real patient intra-oral scans into a haptic simulator for surgical training and planning prior to executing full mouth rehabilitations. This is improving the precision and predictability of fixed prosthodontic management of generalised severe erosive tooth wear. 

Learning Objectives

  • Relate recent research insights into the diagnosis and prevention of erosive tooth wear from acid erosion, tooth attrition and abrasion using CAD/CAM technology
  • Evaluate the role of intra-oral scanning for diagnosing enamel wear 
  • Appraise novel methods for accurate and precise monitoring of enamel wear using surface metrology software to measure surface changes to teeth during wear
  • Illustrate how CAD/CAM can connect to Augmented Reality Haptic Simulators to enhance the planning of crown preparations for Severely Worn Dentitions
  • Connect traditional methods for planning and providing crown preparations for worn dentitions with new Augmented Reality Surgical planning technology to understand the treatment of severely worn dentitions
