“…The demand for the use of aesthetic ceramic restorations increases every year and there is a growing concern for the longevity of indirect restorations, trying to avoid the causes of the failure of these restorations. [1,2,7,[14][15][16].…”

“…The use of the Er: YAG laser associated with adequate parameters found in the literature, allowed us to eliminate unsatisfactory ceramic restorations, reducing working time by 75% compared to traditional methods such as manual crown extractors or burs; providing comfort, speed and protection of the remaining substrate [16]. In the same way, the use of the Er: YAG laser associated with adequate parameters will avoid an increase in intrapulpal temperature, which could cause irreversible damage such as pulp necrosis, unlike the CO 2 and Nd: YAG laser [1,12], which produce an increase in intrapulpal temperature because its absorption is slower than Er: YAG [12], therefore it will produce more heat.…”

“…However, failures can occur in the indication, selection of materials, types of preparation, molding techniques, failure of cementation, finishing, occlusal adjustment and case follow-up [1,5,11]; all of these steps must be followed carefully. In this report, the patient's complaint was related to the color of the cemented porcelains.…”

“…The challenge is currently in the process of removing ceramic restorations, as there is a concern regarding damage to the dental structure, caused by the increase in intrapulpal temperature generated by the friction of the high speed drill, cutting time of the Ceramic restoration and wear of the remnescent structure, which provide patient discomfort [1,2,4].…”

Background: To present the benefits of high power lasers (Er: YAG and Nd: YAG) over the use of the high speed turbine for the extraction of ceramics restorations, without damaging the surfaces of the teeth; being a relatively easier and faster procedure without the use of anesthetic agents, and the preparation of the ceramic restorations and cementing in the single session; with a follow-up of 1 year. Objective: The benefits of lasers over high-speed turbine mechanical instrumentation for crown removal encompass efficient restoration recovery without damage to tooth surfaces; and a relatively easier and faster procedure without the use of anesthetic agents. Methods: The Er: YAG laser (no contact; 3.2-4.0 W, 20 Hz) was used to extract the porcelain prosthesis, followed by a gingivectomy with the Nd: YAG laser on tooth 12 to improve the gingival contour. The dental surfaces where the ceramic prosthesis will be cemented were scanned. Then, CAD / CAM technology was used to make the ceramic veneers that were cemented in the same session. Results: The efficacy the Er:YAG laser energy was observed by the decreased of the time to remove all-ceramic materials through ablation of bonding cements, reducing working time by 75% compared to a high-speed turbine. Conclusions: An Er: YAG laser can safely remove lithium disilicate crowns with the settings used in this study. Laser-assisted removal of all ceramic PDFs is a promising treatment protocol. The use of the Nd: YAG (2.0 W power, short 20Hz, 320 µm optical fiber, in contact) laser allowed gingivoplasty to be performed, automatically cauterizing avoiding post-operative bleeding, and facilitating the preparation of ceramic restorations the same day. The use of high-power lasers and the use of accompanying CAD / CAM technology allowed this clinical case to be completed in a single visit without the use of temporary restorations, achieving absolute patient satisfaction.
