Recuperação da harmonia dos dentes anteriores por meio de implantes e restaurações cerâmicas

Introdução: a ausência ou alterações da estrutura dentária, principalmente em áreas estéticas, compromete a aparência, as relações sociais, a autoestima e, consequentemente, a qualidade de vida do indivíduo. Atualmente, avanços tecnológicos e científicos na Odontologia têm possibilitado várias opções de tratamentos reabilitadores e restauradores que oferecem resultados cada vez mais seguros e confiáveis. Objetivo: relatar, por meio de um caso clínico, a recuperação da harmonia dos dentes anteriores com a utilização de laminados de cerâmica e prótese sobre implante associada a recursos para recuperar a estética gengival. Conclusão: o planejamento adequado, associado aos conhecimentos de uma Odontologia integrada, possibilita resultados extremamente satisfatórios, resgatando a função e a estética, tanto dentária quanto gengival, proporcionando um sorriso harmonioso e o bem-estar social do paciente.

Avaliação da biocompatibilidade de implantes de silicone gel em subcutâneo de ratos: estudo histomorfométrico

Objective: Histomorphometric study to evaluate the biological tissue compatibility of silicone implants suitable for plastic surgery. Methods: Thirty Wistar white rats received subcutaneous implants ande the revestiment of silicone gel Silimed, and randomized into six groups of five animals each, according to the type of implanted material and the time of sacrifice. Eight areas of 60.11 mm2 corresponding to the obtained surgical pieces were analyzed, counting mesenchymal cells, eosinophils, and foreign body giant cells, observing an acceptable biocompatibility in all implants, for subsequent statistical analysis by Tukey test. Results: Silicone gel showed inflammation slightly greater than for other groups, with tissue reactions varying from light to moderate, whose result was the formation of a fibrous capsule around the material, recognized by the organism as a foreign body. Conclusion: In general, it is possible to affirm that silicone gel had acceptable levels of biocompatibility, confirmed the rare presence of foreign body giant cells, and when of the rupture, formed a fibrous capsule around the material, separating the material of the organism.

Utilização de biomateriais poliméricos associados a implantes dentários: revisão de literatura

A remodelação óssea é um processo contínuo, que possibilita a substituição de osso envelhecido e danificado por tecido novo. A reparação ao redor de implantes osseointegráveis e enxertos ósseos em situações desfavoráveis depende do estabelecimento de um adequado contato entre tecido ósseo e implante por meio da estabilidade primária. Tendo em vista a importância da estabilidade primária do implante na biomecânica e conseqüente osseointegração, a associação de biomateriais reabsorvíveis ao sítio de instalação dos implantes se torna relevante. Destes biomateriais, destaca-se o copolímero de ácido polilático/ poliglicólico (PLA/PGA), que poderia contribuir com a estabilidade temporária dos implantes.

Reabilitação protética de mandíbula atrófica por meio de implantes curtos: relato de caso clínico com oito anos de acompanhamento

This case report shows how the prognosis of severe mandibular atrophy can be improved with the use of short dental implants. A Caucasian 54 years-old male patient received four dental implants in the anterior mandibular region. Four months later, the definitive prosthesis was delivered. At the 8-year follow-up period, no complaints or loss of integration were reported. Short dental implants with complete, fixed definitive prosthesis can be a successful treatment in the mandibular arch.

Implantes pós-exodônticos: relato de caso

With the search for treatments faster and aesthetic improvement of materials and surgical techniques, immediate implants have become a clinical reality increasingly practiced. Thus, based on literature the specific purpose of this study was to address critically the concepts of immediate implants, discussing issues related to dental extraction, milling technique, care of the periodontal tissues support and protection, prosthetic replacement, benefits, indications and contraindications. To this end, from Pubmed electronic crawler Medline, 54 articles published between 1990 and 2009, over 4 items classics, all in English were selected. The Studies have shown success rates for this technique Conventional techniques like two-stage surgery, many different techniques and planning are present among these techniques, and implants more immediate subject to failures.

Estudo retrospectivo de implantes osseointegrados instalados imediatamente após exodontias

Objectives: to evaluate implant survival immediately placed after tooth extraction considering different sites, prosthodontic modalities, and the need for biomaterials. Material and methods: dental records of 500 patients treated with dental implants between 2004 and 2011 were screened. Results: only 200 records (20%) corresponded to immediate implants. Reasons for tooth extraction included extensive caries, bone loss, and root fractures. From the 197 immediate dental implants, 86 were placed in the maxilla with a survival rate of 93.9% and 111 in the mandible (survival rate of 99.1%). The overall survival rate was 97.46%. Prosthodontic modalities identified were: Brånemark classic complete denture screwed prostheses (36%), overdentures (5.6%), fixed partial denture (31%), and single-tooth prostheses (27.4%). Also, it was observed that in 33% of cases there was a need for the use of grafts and/or biomaterials. Conclusion: it can be concluded that, when correctly indicated, immediate implants are an excellent choice. The anterior mandibular region, screwed and overdenture-type prostheses presented higher success rates when associated to immediate implant placement. The need for bone graft/biomaterial does not affect the clinical results.

Avaliação do índice de sucesso dos enxertos autógenos e dos implantes instalados em região de seio maxilar

Maxillary sinus lifting surgery is considered an excellent option for patient rehabilitation in cases of maxillary sinus pneumatization. This longitudinal study was performed in 41 patients to evaluate 51 maxillary sinus lifting procedures concomitant to autogenous bone grafted from mandibular ramus. Of the 107 implants installed, 28 were immediate fixations. Success index achieved regarding to bone graft was of 98.04%. The implants installed immediately or after bone grafting resulted in success rates of 92.86% and 94.59% respectively, with no statistically significant differences between them. Surgeries for bone grafting and immediate installation are considered a reliable treatment alternative provided that both anatomical structures and tissue physiology are kept in good conditions, with appropriate indication and techniques for good implant stability.

As mamas de Angelina Jolie e as relações de corpo, cultura e comunicação no discurso da revista Veja

This article analyzes the representation made by Veja magazine about american actress Angelina Jolie about the news about her preventive double mastectomy wich she was submitted. Based on the reflections of Michel Foucault, Gilles Deleuze and Felix Guattari on discourse analysis this article does not cramp about the contributions of linguistics. These reflections contribute to the understanding of this fact within the media landscape to control and discipline the body.

Alternativa protética para correção da angulação com componentes não indexados sobre implantes Cone Morse indexados: sistema tubo parafuso

From a recent perspective the morse-taper dental implants connections are increasingly being used as an alternative for replacement of a missing teeth. Nevertheless, there are a large variety of prosthetic components available on the market with some limitations regarding the final prothesis. This article demonstrated the difficulties and limitations of prosthesis implant-retained connections when using morse-taper implants (with a prosthetic index) case in which the surgical placement of the implant wasn’t successfully performed. The alternative to overcome this scenario was the technique using the tube screw over the top of a mini abutment component. It was possible to manufacture and to have satisfactory adaptation, achieving the satisfaction of the patient, restoring function and esthetics.
