The use of CAD/CAM technology has allowed the fabrication of ceramic restorations efficiently and with predictable results. Lithium disilicate is a type of glass ceramic material that can be used for the elaboration of laminate veneers, being monolithic restorations which require characterization through a covering ceramic in order to achieve acceptable esthetic results. The next case report shows a predictable clinical protocol for the rehabilitation of the anterior teeth through the preparation of CAD/CAM veneers (e.max CAD, Ivoclar Vivadent, Liechtenstein) which have been characterized by a nanofluorapatite ceramic (e.max Ceram, Ivoclar Vivadent, Liechtenstein) through the layering technique.

Rehabilitation of worn dentition is a challenging task because several predisposing factors may be included in the pathogenesis. The treatment options and process should be carefully considered based on the clinical condition and patients’ requirements. This case report represents the esthetic rehabilitation of a 68-year-old patient who exhibited severely worn teeth caused by attrition and erosion. After clinical evaluation, 3 mm increase in occlusal vertical dimension was planned with partial lithium-disilicate ceramic restorations as laminate veneers for anterior teeth and vonlays (onlays with veneer extentions) for posterior teeth in maxilla. The adaptation of the patient to the increased occlusal vertical dimension was tested for 1 month by provisional direct composite restorations. As the patient did not show any discomfort, definitive restorations were completed. The patient was satisfied with the esthetics and functionality of her new dentition.

Introdução: O restabelecimento de um sorriso harmônico constitui um grande desafio para a odontologia restauradora. A sincronia entre diversas especialidades se faz necessária para diagnosticar e tratar alterações estéticas, buscando a excelência do resultado e a satisfação do paciente. Um método bastante citado na literatura e aplicado por muitos clínicos é baseado na teoria da regra de proporção áurea. Quando adotada para situações complexas a proporção áurea pode ser um ponto de referência para a reabilitação. Deste modo, o trabalho tem como objetivo demonstrar uma reabilitação estética de diastemas múltiplos após tratamento ortodôntico, por meio de laminados vitrocerâmicos reforçados com dissilicato de lítio, onde o conceito de proporção áurea é aplicado. Descrição do caso clínico: Primeiramente, o plano de tratamento consistiu na distribuição uniforme dos diastemas, sendo posicionados da maneira mais harmônica e favorável para a oclusão na reabilitação com laminados vitrocerâmicos. A segunda fase consistiu na cimentação dos laminados, a fim de obter um resultado estético agradável. Discussão: A associação de ortodontia prévia a instalação dos laminados, permite uma melhor harmonia estética e oclusal, garantindo uma longevidade do tratamento. Opções restauradoras como laminados vitrocerâmicos reforçados com dissilicato de lítio permitem reabilitações extensas minimamente invasivas. Para casos complexos a proporção áurea, quando alinhada com os conceitos de macro e microestética, pode levar ao sucesso estético.Descritores: Estética Dentária; Facetas Dentárias; Diastema.ReferênciasSoares GP, Silva FAP, Lima DANL, Paulillo LAMS, Lovadino JR.

Laminate Veneers

Since the introduction of porcelain laminate veneers in the early 1980s, the anterior esthetic rehabilitation with PLVs has been provided with a conventional restorative technique for many years. Recently, a new concept named digital workflow has been raised that will lead to the abandonment of conventional procedures during the fabrication of PLVs. Digital workflow is a new concept facilitating applications by adapting digital systems to clinical applications, including intra- and extraoral photographs, diagnostic wax-up, mock-up, intraoral camera, and use of the CAD/CAM device. The aim of this case report is to describe the clinical procedures of porcelain laminate veneers using digital workflow with a facilitating step in a single session and to evaluate the PLVs after one year of clinical service.

SUMMARY The expectation of an esthetically harmonious smile increases the level of difficulty when treating patients. Laminate veneers stand out as a treatment option for cosmetic rehabilitation in clinical practice, as they are a more conservative procedure and mimic dental structures. These laminate veneers are generally made with different techniques; the most common requires an impression of the prepared tooth, an impression antagonist, fabrication models, and extensive laboratory time. The computer-aided design/computer-aided manufacturing (CAD/CAM) system optimizes the fabrication of prosthetic structures, reducing chairside time and promoting good esthetic results. Thus, the purpose of this case report is to present the esthetic result of multiple CAD/CAM manufactured laminate veneers using a new self-etching glass ceramic primer with a lithium disilicate ceramic, using the modified correlation and biogeneric modes.

Abstract Aim The aim of this report is to present five-year follow-ups of two different applications for the use of direct laminate resin-based composite veneers to improve esthetics. Background Defects in the maxillary anterior teeth, such as enamel hypoplasia and peg lateral, can present esthetic challenges. Furthermore, a treatment plan that can be completed in a single appointment is highly desirable. This case report presents two different clinical cases involving the use of direct laminate resin-based composite veneers with five-year follow-ups. Case Report Case 1: A 17-year-old female patient was referred for treatment of her anterior teeth, which were unesthetically altered due to enamel hypoplasia and dental caries. A treatment plan was developed that included restoring the affected teeth with direct resin-based composite laminate veneers to improve the patient's appearance. The six maxillary anterior teeth were prepared for and restored with direct resinbased composite laminate veneers. At the fiveyear follow-up, the patient was satisfied with the restorations both esthetically and functionally. Case 2: A 15-year-old female patient also was referred for treatment to improve the appearance of her maxillary anterior teeth. A treatment plan was developed with two objectives: (1) to restore the undersized supernumerary crown in the area of the maxillary right lateral incisor and (2) to close the anterior diastemas. The facial surfaces were conservatively prepared and resin-based composite was applied with the aid of transparent crown forms. After completion of the treatment, the patient was recalled at six-month intervals. At the five-year follow-up appointment, the restorations were intact, no adverse effects were noted, and the resultant appearance was highly satisfactory for the patient. Summary The use of direct resin-based composite laminate veneers and adhesive bonding systems has been shown to provide an esthetic alternative to metal-ceramic or all-ceramic crowns for the rehabilitation of anterior teeth. This treatment option offers another advantage, namely a lower cost compared to an indirect technique. Other more complex and costly treatment options in the future are not ruled out. Clinical Significance In the present two cases, the initial and five-year follow-up results support the use of direct resin-based composite laminate veneers with minimal altering of healthy tooth structure. Such results should encourage clinicians to seek a cost-effective technique such as direct resin restorations to improve a patient's esthetic appearance in a single appointment.
