A review on laser-assisted veneer debonding

This literature review examines the advancements in laser technology that have enhanced the veneer debonding process, offering insights into the proper implementation of these techniques in clinical practice with emphasis on laser parameters, debonding efficiency, thermal effects, and preservation of tooth structure. A systematic literature search was conducted on PubMed,Web of Science, Scopus and Cochrane Library. The review was structured according to the PICO framework. The search was performed independently by two reviewers on laser-assisted debonding of ceramic veneers using Er:YAG or Er,Cr:YSGG lasers.Based on a comprehensive evaluation of existing studies, the review presents different types of prosthetic restorations, materials, and laser parameters, and how they interact with each other. The benefits of laser precision, including improved control, workflow efficiency, fewer procedural steps, and reduced tissue impact, are emphasised to help dental practitioners enhance the standard of care in veneer debonding. Across the twenty nine studies that were obtained, laser debonding facilitated removal while pulpal temperature increases remained below commonly cited critical values. Both Er:YAG and Er,Cr:YSGG systems demonstrated effective veneer removal. Thinner veneers nedeed less irradiation time and lower energy. Limited enamel alterations occured when appropriate parameters were used. Current studies suggest that Er:YAG and Er, Cr: YSGG lasers offer clinical advantages in terms of efficiency, safety, and patient comfort. Studies demonstrate that optimized laser settings reduce debonding time and minimize the risk of thermal damage to underlying tooth structure and surrounding tissues. Debonding efficiency was influenced by veneer thickness, ceramic type, cement composition, laser power, pulse duration and cooling protocols Er:YAG and Er,Cr:YSGG lasers are promising tools for ceramic veneer debonding. However, results obtained in these studies cannot be directly associated to patient-centered issuses, further standardized clinical studies are required before definitive clinical recommendations can be made.
