Removing All-Ceramic Restorations Using an Er,Cr:YSGG Laser
Patrick J. Broome, DMD, MBA
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.
