Laminate Veneers

As reforçadas propriedades intrínsecas dos materiais cerâmicos, associados à adesão resinosa fundamentam a desenvoltura de técnicas restauradoras mais simplificadas, conservadoras e sem a necessidade de preparo dental prévio seja em dentição anterior ou posterior. Assim sendo, o trabalho tem como objetivo apresentar dois casos clínicos os quais abordaram a confecção de restaurações delgadas em dissilicato de lítio cimentadas sobre diferentes áreas dos arcos dentários, enfatizando o mesmo protocolo clínico, ou seja, ausência de preparos dentais e consequentemente a cimentação resinosa adesiva das restaurações. Caso Clínico 1: laminados cerâmicos nos elementos 13, 12, 11, 21, 22 e 23; Caso Clínico 2: facetas delgadas sobre os elementos 34, 35, 36 e 37. Ambos os casos clínicos com 1 ano de acompanhamento após a cimentação das restaurações. Conclui-se que houve a recuperação da estética e da função em ambos os casos apresentados e a confiabilidade e o sucesso em longo prazo do protocolo clínico descrito estão diretamente relacionados ao substrato dentário, aos fatores de adesividade dos materiais e as propriedades intrínsecas das cerâmicas.Descritores: Cerâmica; Estética Dentária; Facetas Dentárias; Cimentos de Resina.ReferênciasMurdoch-Kinch CA, McLean ME.

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

The success of rehabilitation will not depend on just clinical procedures. A proper dental technique (ceramist) is required as well as the respect for some biomimetic principles to obtain the desired final result. This study has the purpose of describing a prosthetic rehabilitation with laminate veneers and all-ceramic crowns of a patient unsatisfied with a previous esthetic treatment because of the negligence of some biomimetic principles. A 45-year-old female patient was admitted to the dental clinic complaining about the lifelike appearance of her all-ceramic restorations. Before the fabrication of new restorations, a mock-up was conducted to verify the patient’s satisfaction. A ceramist conducted all the fabrication process so that surface characterizations could be visually verified and the lifelike appearance of natural tooth could be reproduced. After the cementation procedure, the patient reported being satisfied with the lifelike appearance of the new restorations. Based on the clinical findings of the present case report, it can be concluded that the reproduction of the lifelike esthetic appearance of natural teeth and the visualization of the final results before definitive procedures are essential to obtain the clinical success.

Ceramic Restorations

The rapid developments in biomaterials has led not only to improved materials but also to the development of clinical techniques made possible by these advances. Adhesive dentistry remains one of the fastest changing fields and this will most likely continue well into the next decade. Patients’ aesthetic awareness and, to some extent, concern about amalgam has produced a growing demand for posterior tooth-coloured restorations. Originally this was met by ceramo-metal crowns and subsequently by the development of posterior composite resins. Recent development of stronger ceramics and better luting have now made all-ceramic restorations possible in posterior sites. Several new techniques for cavity preparation are emerging as alternatives to the conventional handpiece while the quest for amalgam alternatives continues. As with all recent developments there are, by definition, few long-term clinical data yet available to allow a comprehensive evaluation of the relevant materials and techniques. This paper is a summary of the most significant recent advances in fixed prosthodontics and operative dentistry.

Laminate Veneers

Ceramic laminate veneers have been widely used in esthetic restorations, with advantages such as color stability, resistance to degradation, and excellent esthetic results, all of which contribute to long-term stability. The gold standard technique consists of bonding a thin ceramic laminate veneer to enamel. The present paper describes a clinical case with 3-year follow-up. Six ceramic laminate veneers were planned, fabricated and bonded to six sound anterior maxillary teeth showing diastema, thereby improving shape and size. The procedure followed a laminate veneer treatment protocol, using a mock-up, shade selection, and an adhesive system. The case was followed for 3 years. In conclusion, minimally invasive restorations with ceramic laminate veneers remained stable after 3 years of follow-up and are a good option for patients with diastema or microdontia and requires only a minimum amount of sound tooth tissue removal.

The IPS e.max system by Ivoclar Vivadent, offering a variety of products and indications, is widely used for all-ceramic restorations. We analyzed the clinical track record of these products in daily clinical practice, associating their restorative survival rate with various parameters to define recommendations for long-term stability. A total of 1058 full-coverage crowns and fixed partial dentures (FPDs) were evaluated retrospectively over up to 66.48 (37.05 ± 18.4) months. All were made of IPS e.max Press, IPS e.max CAD, IPS e.max Ceram or IPS e.max ZirPress and had been delivered by a private dental practice within three years. Uses not recommended by the manufacturer were also deliberately included. The five-year cumulative survival was 94.22% (i.e., 94.69% or 90.58% for glass-ceramic crowns or FDPs and 100% or 90.06% for zirconia-based crowns or FDPs). Significantly superior outcomes emerged for conventional vs. adhesive cementation and for vital vs. non-vital abutment teeth, but not for recommended vs. non-recommended uses. Caution is required in restoring non-vital teeth, but the spectrum of recommended uses should generally be reconsidered and expanded, given our finding of high survival and success rates for IPS e.max ceramics, even for uses not currently recommended by the manufacturer.

Ceramic Restorations

With increasing patient expectation for aesthetic dental restorations, there has been a drive towards developing ceramic materials to meet this expectation. Multiple ceramic systems have been introduced over the past four decades with considerable advances in material properties. Survival rates of all-ceramic crowns differ by type of ceramic used, fabrication method and clinical indication. Zirconia and lithium disilicate are the most commonly used contemporary ceramic materials in dentistry. Survival data for these types of restorations appears to be promising; however, there is a lack of high-quality long-term clinical data on the success of these restorations. In the absence of robust longitudinal clinical research, laboratory studies have provided some useful information on the performance of ceramic restorations. Further high quality long-term clinical studies are needed to inform us of modes of failure of these restorations and the range of clinical circumstances in which each type of ceramic restoration may be used.
