Ceramic bracket debonding with Tm:fiber laser [PDF]

open access: yesJournal of Biomedical Optics, 2016
Lasers have the potential for reducing the required debonding force and can prevent the mechanical damage given to the enamel surface as a result of conventional debonding procedure. However, excessive thermal effects limit the use of lasers for debonding purposes.
