Reabilitação estética do sorriso por meio do sistema cerâmico dissilicato de lítio: relato de caso

The reestablishment of a harmonious smile through dental ceramics, when properly conducted and with specific indications, can achieve extremely predictable results. For aesthetic and functional rehabilitation, many ceramic materials can be used such as zirconia, leucite, alumina, feldspar, and lithium disilicate. Among these materials the lithium disilicate stands out due to the following characteristics: its resistance to wear, to chemical attack, high temperatures and oxidation; low electrical conductivity; near zero thermal expansion; good optical properties and biocompatibility with periodontal; excellent esthetics; color stability and reinforcement of tooth structure. The indications for the use of lithium disilicate are not limited to multiple facets of teeth in cases where there was no favorable response to tooth whitening, and also comprehend teeth with multiple restorations, diastema closure, shape alteration, and dental contouring, replacement of missing or fractured teeth, among others. The versatility of lithium disilicate ceramics allows its utilization in several clinical situations. The concomitant use of lithium disilicate for veneers and over metal has satisfactory aesthetic results, as reported in the present studying cases that require both aesthetics and resistance.

Como tais procedimentos, podemos citar o clareamento dentário e a utilização de resinas compostas diretas, que nos fazem praticar o conceito de uma Odontologia minimamente invasiva. Este artigo tem o objetivo de demonstrar, através de alguns procedimentos conservadores, a possibilidade de se obter resultados satisfatórios.

Visão contemporânea sobre pinos anatômicos

As an alternative to improve the adaptation of prefabricated posts in flared canals and weakened roots, the option is for relining prefabricated pin, known as a technique of anatomical post. This technique, which can be made with composite resin increases the adjustment post to the walls of the canal and reduces the cementing line, causing the retaining post is less dependent on the mechanical properties of the cementing agent. This article aims to provide an overview of anatomical posts, specifically in the last two decades, based on studies extracted from Scielo, Scopus and Pubmed, referring to the following terms of MeSH Data Base: custom made fiber post, indirect fiber glass posts, root canal therapy and post and core tecnique. According to the literature review in this article, it can be concluded that this technique has been used by several authors and has been shown effective and promising, it creates an individualized retainer with better adaptation and decreased mechanical imbrication cementing line .

Associação de prótese fixa, implantes e estética periodontal para reabilitação de pacientes parcialmente edêntulos

Periodontitis is a chronic inflammatory disease that results in the destruction of teeth and their supporting tissues with subsequent tooth loss. The replacement of missing teeth for implant-supported restorations has proven to be a highly predictable treatment method with good long-term prognosis. However, some consequences of tooth loss prevents dental implant placement in an ideal position, where regenerative procedures are necessary for this type of rehabilitation. Less invasive procedures such as conventional prosthesis emerge as a therapeutic option in cases where there is enough bone structure for implants and patient´s non-acceptance for invasive procedures. Thus, this paper aims to present the resolution of rehabilitation through a noninvasive and multidisciplinary treatment. One female patient referred to the clinic presented maladaptive bilateral mandibular fixed prostheses, endodontic lesions, gingival recession, and root sensitivity. For proper resolution of this case, an association among osseointegrated implants, fixed partial prosthesis, tooth extraction, and aesthetic periodontal procedures with the use of subepithelial connective tissue graft was proposed. After two years, the patient shows excellent aesthetics and chewing. Within the limits of this scenario, this paper discusses the various factors that may affect the choice of a particular treatment modality for the rehabilitation of edentulous single spaces.

Técnica estrutural: confecção de pilar personalizado cerâmico para otimizar a estética

Na reabilitação protética com implantes, a reconstituição das características anatômicas do tecido peri-implantar é fundamental para a obtenção de uma estética ótima. Como os componentes metálicos não transmitem a luz, fazem com que os pacientes com fenótipos gengivais finos apresentem uma coloração escurecida, resultante da limitação estética desses componentes. Pilares cerâmicos (alumina ou zircônia) têm sido utilizados para resolver esse problema, os quais possibilitam a complementação com próteses metal free. A indústria fornece, para alguns sistemas, componentes pré-fabricados cerâmicos a serem personalizados por desgastes e componentes personalizados confeccionados com sistemas CAD/CAM e CAD/MAN. Tendo em vista as limitações de algumas das conexões desses componentes, o objetivo desse estudo é apresentar a técnica laboratorial para confecção de um pilar personalizado cerâmico realizado sobre pilar UCLA de sobrefundição. Concluiu-se que a utilização da cerâmica feldspática proporciona ótima estética, boa transparência, resistência mecânica, baixo custo, melhor capacidade adesiva, com utilização de cimentos resinosos, e, principalmente, técnica de amplo domínio dos laboratórios.

Reabilitação estética funcional associando onlays em cerômero e resinas nanoparticuladas

Introdução: a perda da dimensão vertical de oclusão (DVO) é resultada de um grande desequilíbrio oclusal, onde não apenas a perda dos dentes pode ser o fator responsável, mas também as parafunções, entre elas, o bruxismo. O restabelecimento da relação maxilomandibular é condição necessária para que uma adequada reabilitação bucal seja executada, devolvendo, assim, função e estética perdidas. Objetivo: descrever um caso clínico de reabilitação em paciente bruxista, com presença de desgastes dentários, desgastes de tratamentos restauradores previamente existentes, fratura de onlay e bordas incisais, restabelecendo uma nova DVO por meio de onlays posteriores em cerômeros, recuperando a estética com restaurações diretas em resinas compostas nos dentes anteriores. Conclusões: a reabilitação bucal com levante de mordida em onlays devolve a DVO perdida de maneira segura.

Reflexões sobre o estabelecimento de vínculos afetivos interpessoais na atualidade

In studies about the subjectivation process in contemporaneity and the social context in which one is inserted nowadays, the contemporary world is often characterized by the ascension of the narcissism – or individualism – and consumerism as a baseline to all other recent changes. The excessive valorization of aesthetics; the influence of media and marketing and the culture of image; the loss of the “inner side” and inter-human interchanges; against the exacerbation of the superficial and external, appear as essential transformations to the new configuration of the so called “post-modern” subjectivation process, privileged and reinforced by capitalist society. Next to them, exists an individual discontent – a malaise in the individual’s life – usually associated to an interior emptiness and general dissatisfaction in face of idealizations and self-esteem fluctuations. This work tries to understand how individuals establish affective bonds and social relationships in this contemporary context, connecting the contemporary context and relevant concepts to this study, including the idea of romantic love, narcissism and the “state of helplessness” in psychoanalysis, subject’s development and a parallel discussion with social-historical texts. The study, of a theoretical character, is located in the intersection between "individual" and "society" – a subjectivity, therefore, formed internally, within the individual, and submitted directly to social influence – and analyzes the determinants and influences that they exert upon one and another, based on critical-reflective readings and textual analysis of works in the fields of sociology, psychosociology and psychoanalysis.

A questão da diferença na sociedade contemporânea: reflexões a partir de zygmunt bauman

The objetive of this article is discuss the question of difference and alterity presents in analyzes of contemporary society conducted by the polish sociologist Zygmunt Bauman. The author observed that human relations are guided by a logic of cost-benefit connected with values of present in the discardability of consumer society. At the same time, it has built ways of eliminating difference through the construction of a politics of expulsion of those considered strangers. For the author, the cities are the materialization of the ambivalence of live with the other people in contemporary times, being the locus of experience approach and retraction to the other expressed by fear of the difference. The result of this process is the impoverishment relational, the feeling of loneliness and an ethical-political crisis seen that could be seen from the primacy of the private/intimate rather than the public dimention/action.

Amizade e a virtualização das relações humanas na sociedade contemporânea: reflexões a partir de Zygmunt Bauman
