Systematic Review of Erbium Laser Assisted Ceramic Debonding

Objectives: Removing bonded ceramic materials from natural teeth or implant abutments can be a challenging task. The removal ceramic restorations or appliances are often damaged and unusable after the retrieval. The application of Erbium lasers offers an alternative non-invasive methods for retrieving bonded ceramics. This systematic review aimed to provide a comprehensive review and overview of the current literature on the effectiveness of Erbium-laser-assisted ceramic retrieval.
Methods: A comprehensive literature search from 7 databases were conducted. The abstracts were reviewed by two reviewers independently. The third reviwer was used to solve the disagreement.
Results: Out of 4117 unique articles, 38 were included in the final full paper systematic review. The data was extracted. Laser-debonding/retrieval of ceramic crowns, veneers, and orthodontic brackets were included. The debonding time depended on the type of restoration/appliance as well as cements and laser. The debonding tempertures were below the levels that would harm pulpal or peridonal or periimplant tissues.The debonded ceramics were most often examined by scanning electron microscopy, sometimes together with derivatives it. There was no reports on structural or chemical damages to the debonded/retrieved ceramics.
Conclusions: Erbium laser assisted ceramic debonding/retrieval is an effective and non-invasive tool. Erbium lasers appear to be safe to natural teeth or implants and debonded/retrived ceramics. However, there is a need for clinical studies.
