The Dahl Principle - Incisal Edge Bonding

This lecture covers how to apply the Dahl Principle day-to-day in restorative dentistry. The Dahl Principle is about creating space to treat localized anterior tooth wear by separating the posterior teeth using an anterior bite plane for 4-6 months.

Dr. Tif Qureshi will show how the Dahl Principle can be used as an interceptive treatment combined with traditional occlusal theory to prevent the need for more aggressive tooth preparation in your patients’ mouths, either now or years down the line.

The Dahl Principle is a radically different approach to traditional occlusal techniques and will certainly give you something to think about!

The Dahl Principle is often used in combination with other treatments and is a must-have tool for the minimally invasive focused dentist.

You will learn: 

  • The history of the Dahl Principle and the Dahl Concept.
  • The loss of occlusal space.
  • Modern uses with minimally invasive dentistry.
  • The setup of guidance.
  • One stage vs. two stage treatment.
  • Incisal edge bonding techniques and materials.
  • Multiple case studies.
  • Use with Alignment, Bleaching, and Bonding techniques.

Case 1

This patient was complaining about darkening ageing teeth and from worn lower teeth. Uppers were aligned, bleached/ whitened and the lowers were directly edge bonded to increase the anterior OVD using the Dahl Principle. In this case the Dahl appliance acted as a splint and no further external splint has been needed. Follow up photos are at 8 years with no repairs or replacements needed on the anterior bonding. 

Case 2

This patient presented in 2006 complaining of some joint pain and clicking and breaking back teeth. Canine guidance had been lost and posterior interferences were evident on lateral and anterior slides. Inman Aligners were used to widen the canines, fix retain and direct dahl bonding was applied to open the anterior bite - allow posterior eruption and improve anterior and canines guidance. 10 years laters guidance and virtually all bonding remains from the original placement and no splint has been needed to control any further bruxism.
