Summary
Erbium lasers offer a noninvasive method for removing ceramic restorations and appliances from teeth and implants. This laser-assisted debonding is effective and safe, presenting a viable alternative to traditional rotary instruments.
Area of Science:
- Dental materials science
- Laser dentistry
- Restorative dentistry
Background:
- Traditional removal of ceramic restorations can be invasive and time-consuming.
- Erbium lasers present a potential noninvasive alternative for debonding ceramic appliances.
Purpose of the Study:
- To comprehensively review the current literature on the effectiveness of erbium lasers for removing ceramic restorations and appliances.
- To evaluate the efficacy of erbium lasers on natural teeth and dental implants.
Main Methods:
- A systematic literature search was conducted across seven major databases.
- Inclusion and exclusion criteria were pre-defined, with independent screening by two reviewers.
- Thirty-eight full-text articles were reviewed for data extraction.
Main Results:
- Erbium laser removal times vary by restoration type, with zirconia taking longer than lithium disilicate.
- Pulpal temperature rise was minimal (≤5.5 degrees Celsius).
- No structural damage to debonded ceramics was observed.
Conclusions:
- Erbium lasers effectively and safely remove ceramic restorations from teeth and implants noninvasively.
- Laser-assisted debonding is a viable alternative to rotary instrumentation for ceramic crowns.
- Further clinical studies are recommended to support erbium-assisted ceramic retrieval.
