Clinical long-term evaluation and failure characteristics of 1,335 all-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.

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.

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.

AbstractCeramic implant abutments are becoming increasingly popular due to the growing esthetic demands of patients. Two-piece ceramic abutments have the advantages of both ceramic and titanium abutments. This study aimed to review the published articles regarding hybrid abutments and their characteristics.Published articles regarding two-piece abutments were retrieved by electronic search of PubMed, Embase, Scopus, Medline, and Google Scholar databases using certain keywords. Articles highly relevant to our topic of interest were selected and reviewed.The presence of titanium inserts in hybrid abutments can overcome the brittleness of ceramic, increase the overall fracture resistance, prevent the implant connection wear, and provide better marginal fit compared with one-piece zirconia abutments. Hybrid abutments enable the fabrication of monolithic metal-free implant restorations with optimal esthetics. Furthermore, the risk of porcelain chipping, which is a common complication of implant restorations, is eliminated due to the monolithic structure of these restorations.According to the available literature, hybrid implant abutments have shown promising results with regard to optimal esthetics in the rehabilitation of the esthetic zone. However, long-term clinical studies are required to assess the long-term durability of all-ceramic restorations supported by hybrid abutments.
