New restorative materials called compomers offer improved properties over traditional glass ionomers. A novel technique for reattaching fractured teeth using dentin bonding agents can restore significant tooth strength.

Area of Science:

  • Restorative Dentistry
  • Dental Materials Science

Background:

  • Conventional glass ionomers have limitations in physical properties and clinical applications.
  • Fractured tooth fragments present a challenge in restorative dentistry.

Purpose of the Study:

  • To review compomers as a new fluoride-releasing restorative material.
  • To evaluate the technique of reattaching fractured tooth fragments using dentin bonding agents.

Main Methods:

  • Comparison of compomers and glass ionomers based on classification, physical properties, and clinical usage.
  • Review of clinical and laboratory data supporting tooth fragment reattachment with dentin bonding agents.

Main Results:

  • Compomers exhibit physical properties (translucency, thermal expansion, strength) closer to composite resins than glass ionomers due to the absence of an acid/base setting reaction.

  • Tooth fragment reattachment using dentin bonding agents can restore up to 50% of original tooth strength without tooth preparation.
  • In vitro studies show potential for 100% strength restoration with porcelain veneer bonding after reattachment.

    • Conclusions:

    • Compomers represent a distinct class of restorative materials with properties differing from conventional glass ionomers.
    • Dentin bonding agents offer a viable, minimally invasive technique for restoring fractured teeth, significantly improving mechanical strength.
