Reparo periapical de dentes tratados endodonticamente submetidos a movimentação ortodôntica

The relationship of Orthodontics and Endodontics is being clarified with the development of evidence-based dentistry. However, few studies have reported the repair of periapical lesions with orthodontic treatment. Therefore, the aim of this study was to evaluate the available evidence on periapical repair of endodontically treated teeth during orthodontic movement. The strategy used was the electronic search with keywords and criteria including studies published up to July 2011. It was also carried out qualitative assessment of the articles methodology. Although a significant number of studies have reported this topic, only two filled the criteria for inclusion in this systematic review. The results obtained in the literature suggest that orthodontic treatment should be interrupted to perform endodontic treatment. During this therapy, the use of root canal dressing based on calcium hydroxide for at least 14 days, and sealer with adequate biological property are indicated. After this phase, orthodontic movement of the endodontically treated teeth can be resumed without waiting period.

O uso de rhBMP-2 para aumento ósseo maxilar: relato de caso clínico

The bone resorption in the anterior maxilla, due to its aesthetic importance, can be considered one of the challenges in implant dentistry. Autogenous bone graft is the most indicated bone augmentation procedure, aiming an implant supported rehabilitation.. Alternatively, some other graft procedures can be done with homogenous and xenogenous bone graft, biomaterials and different associations. Additionally to the mentioned biomaterials, the bone morphogenetic protein (BMP), specially the rhBMP-2, which was characterized as a bone osteoinductor, and consecutively, a potential autogenous graft substitute, with previsibility and no necessity of association to other biomaterial. The objective of this study is to present a single case using the rhBMP-2 for bone augmentation.

O uso do beta-tricálcio fosfato como substituto ósseo em odontologia

The correction of bone defects is the restoration of lost structures which can be replaced by alloplastic implants or bone grafts. Due to the known disadvantages of removal of autogenous grafts, most researches in dentistry aim to develop alloplastic or non-alloplastic materials able to replace bone without these limitations. Beta-Tricalcium Phosphate (β-TCP) is a synthetic granular bone substitute, biocompatible, osteoconductive, which can be used in the alveolar reconstruction. In this work, we perform a literature review on the β-TCP characteristics and discuss its application in dentistry.

Tecido ósseo homólogo para utilização em odontologia

The use of bone grafts from bone tissue banks, also known as bone allografts, has increased in the last years, although most of its users still have concerns on resources and processing protocols. The objective of this paper was to make a literature review about the use of bone allografts in Dentistry, and also about the legal considerations regarding this biomaterial. Studies regarding the donor selection, the cross-infection risks and processing protocols of this biomaterial are still rare but essential, and allied to those regarding its clinical application, can base its use.

Uso de um distrator ósseo dentoimplantossuportado, feito a partir de tornos expansores convencionais, na reabilitação oral

Osteodistraction is a clinical reality, available in the last decades for the resolution of large bone deficiencies, in cases that there are pre-existing, but misplaced implants and teeth. The aims of thearticle is to present a case report in which a new possibility for bone distraction, based on tooth-implant bone distractors, made from standard orthodontic expansion-screws, was used in an area where there was an extensive need of alveolar bone and aesthetical recovery, allied to teeth and dental implant misplacement. This technique presented good clinical results, associated to effective simplicity and low cost, becoming viable clinical solution for bone tissue augmentation and aesthetical optimization. In resume, it is possible to say that the suggested technique achieved its objectives, improving the hard and soft tissue profile, whilst allowing completion of oral rehabilitation.

A utilização do enxerto ósseo autógeno para tratamento de lesão de furca grau II

Destruction of bone and periodontal ligament as a result of periodontal disease can lead to anatomical defects in the furcation area. Treatment of these lesions is a major challenge to the clinician. Periodontal instruments have limited access to this area and plaque and calculus removal from root surfaces are extremely difficult. For proper treatment planning a number of factors must be taken into consideration to achieve immediate and long term success. Surgical therapy associated with bone grafts may be a viable option in the treatment of class II furcation defects, aiming to restore lost tissues. The aim of this paper is to report a clinical case where a simplified surgical approach with the use of autogenous graft was used to treat a class II furcation defect Twelve months after the surgery, an increase in clinical attachment level and pocket depth reduction resulted in a complete closure of the furcation lesion.

Reparo de uma restauração classe IV com o uso de resina composta nanoparticulada: quatro anos de acompanhamento

O aprimoramento da odontologia estética restauradora está ligado ao desenvolvimento de materiais e técnicas inovadoras, os quais podem oferecer diversos benefícios, incluindo a integração cromática, policromatismo, forma anatômica, função, adequado contato proximal e aumento da integridade marginal. Em função desses aspectos, as restaurações de resina composta, aplicadas de forma direta, tendem a ganhar maior longevidade. Assim, o objetivo do presente relato de caso é fornecer ao leitor a visão dos desafios restauradores envolvidos no reparo de uma fratura classe IV de um dente incisivo superior, utilizando-se um novo sistema de resina composta híbrida nanoparticulada (FiltekTM Supreme - 3M ESPE). Resultados: com base no referido material e técnica, otimizamos a obtenção de resultados satisfatórios alcançados por meio da utilização adequada do sistema adesivo e resina composta, mantidos com sucesso após o acompanhamento de 4 anos. Conclusão: pode-se concluir que, interagindo técnica adequada de aplicação, princípios adesivos básicos e materiais de qualidade, o clínico pode garantir o sucesso na restauração da forma, função e estética de dentes anteriores.
