Introduction: Esthetics dental treatments involving ceramic laminate veneers can obtain optimal results through detailed considerations with respect to teeth preparations, gingival margins and esthetic factors. Objectives: This case report aims to present a conservative management for ceramic conservative preparation associated with the digital workflow for ceramic laminates, with 18-month follow-up. Case Report: Patient complaining of a child smile due to diastemas in the anterior region. The planning and design of the smile was carried out using a software (Keynote, Ceramill Mind). After molding and printing a 3D model, a mock-up was performed, which was used as a surgical guide for the performance of gingivoplasty. The conservative dental preparation was then performed, with cervical enamel preservation. The ceramic laminates were made after molding and scanning the model, using the CAD/CAM system and cemented on the dental surface. It was observed that there was an increase in gingival quality and thickness, achieving esthetics, color and marginal stability, after 18 months of follow-up. Conclusion: The conservative preparation technique associated with the digital workflow allowed the manufacture of thin ceramic laminate veneer, promoting stability of esthetics and periodontal health after 18 months.

CAD/CAM technology can enhance the dentistry application of ceramic materials that meet the more relevant biocompatibility and aesthetics demands. In implant-borne prosthesis rehabilitation, yttria-stabilized zirconia appeared to be a valid alternative to metal-alloys and titanium, with comparable mechanical properties and even better interaction with bone and soft tissues. The improvement of monolithic CAD/CAM manufacturing allows for a reliable, predictable, and rapid workflow that can correspond to a holistic treatment philosophy associated with zirconia fixtures. This reported clinical case highlights the advantages of this approach in resolving particularly functionally and aesthetically complex situations. A 40-year-old patient with permanent canine impaction and the persistence of a deciduous tooth compromised by caries was successfully rehabilitated with the surgical removal of the enclosed tooth, the seating of a mono-phase zirconia implant after the deciduous extraction and its loading with a zirconia single crown, without any clinical or radiographical alteration up to seven years follow-up.

From the perspective of the design office, this paper examines the manner in which computers are streamlining and changing the design process for today's sailing yachts. Starting with preliminary design and progressing through the more detailed aspects of final design, the computer's varying roles in the design process are traced with examples drawn from currently implemented programs. In addition to its customary role as a bookkeeper, the computer's remarkable graphics capabilities are highlighted. The authors offer a glimpse of what programs and hardware tomorrow's yacht designer will use as frequently as his curves and battens. The paper covers such subjects as design follow-up, sailing analysis and feedback into the original design process. Since designers are not the only ones to benefit from the computer revolution, the authors have included sections on computer generated sailing aids for the yachtsman and possible CAD/CAM applications for the boatbuilder.

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.   Keywords Er:YAG; Nd:YAG; Lithium disilicate ceramic; CAD/CAM.

Laminate Veneers

ABSTRACTThis clinical report describes an 8-year follow-up evaluation using different thicknesses of porcelain laminate veneers of diastema and malformed anterior teeth. Minimally invasive treatment with no preparation or minimal reduction options could be considered and chosen based on the characteristics of each case. Laminate veneers with or without reduction can offer an excellent result regarding esthetics and function. Despite its failure without reduction, this treatment is indicated because it can be applied regardless of the structure of the teeth. At first, no tooth preparation with rotatory instruments was performed, and porcelain laminates of minimum thickness were made for the four maxillary anterior teeth. After 6 years, the adhesive interfaces were stained, and the patient was unsatisfied with the esthetics of her smile. Therefore, at that time, the professional decided to prepare the anterior teeth for porcelain laminate veneers. Diastema closure and/or correction of malformed anterior teeth using porcelain laminate veneers is a viable option for the clinician because it restores esthetic harmony. The patient was very pleased with the new laminate veneers.
