Unmet Need for Wet Dental Adhesive

​​Problems caused by poor wet adhesion:
​ 
  • Frequent failures of composite fillings
  • Difficulty attaching restorative ceramics
  • Detachment of dental brackets
  • Tooth damage from acid etchants​​

"Biomimicry" Provides a New Approach

"Similar to mussels in the marine environment, dental materials in the oral environment have to endure long-term water hydrolysis, mechanical stress and other chemical challenges…."

​Focus Applications
​ 

Orthodontic Devices
​•  Failures due to poor wet bonding
•  Braces, traction of impactions
•  Must be reattached by dentist​ 
Ceramic Adhesion​
•  Detachments common
•  Adhesion to implant materials is
​   difficult, especially zirconia
Composite Fillings
•  Frequent failure of wet adhesion
•  166mm procedures per year (US)
•  60% replacement of failed fillings

Orthodontic Device Attachment

Picture
 
  • Bond bracket to enamel with universal acrylic adhesive
  • Incubate in water overnight
  • Measure bond strength
 
​"Universal" dental adhesive is an acrylic used for orthodontic devices, fillings, crowns, etc. 

Ceramic Adhesion


  • Prime wet/dry zirconia with silane/MDP or MPI-PCS
  • Add universal dental adhesive – light cure
  • Measure displacement force
 
​Optimization of MPI-PCS performance is ongoing.

Composite Fillings

  • Dentin is a spongy, wet tissue
  • Acrylic adhesives display poor wet bonding
  • Acid etching, priming used
  • Most adhesion is mechanical ("resin tags")
  • Resin tags fail over time
  • Filling failure in <7 years
 
60% of filling procedures are to ​replace old, failed fillings
