Removing All-Ceramic Restorations Using an Er,Cr:YSGG Laser

Adhesive bonding lies at the core of aesthetic dentistry and involves various restorative materials that can be used to "mimic" nature. When the removal of a bonded porcelain restoration is necessary, a high-speed handpiece with a diamond bur has been the only option for clinicians to facilitate removal and revela the remaining tooth structure. By using minimally invasive laser technology, however, the clinician may remove a bonded restoration without cutting it off by simply reversing the light- or dual-core resin chemical reaction. Feldspathic and/or pressed ceramic restorations can be removed via an Er,Cr:YSGG Laser, which selectively interacts in water molecules in the adhesive resin and hybrid zones.

*Private practice, Charlotte, NC.


Learning Objectives:

Upon completing this podcast, the listener should:

  • Gain an increased understanding of the clinical procedure involved in using a Er,Cr:YSGG Laser.
  • Understand the benefits of using an Er,Cr:YSGG Laser over conventional diamond bur techniques.
