ABSTRACT

A instalação de implantes em áreas com perda óssea pode estar associada a uma relação coroa-implante desfavorável, resultado estético insatisfatório e dificuldades de higienização, prejudicando o prognóstico do tratamento. O enxerto ósseo possibilita a instalação de implantes em uma posição tridimensional favorável. Alguns métodos têm sido estudados e propostos para a reconstrução do osso alveolar perdido: enxertos ósseos autógenos, homógenos, substitutos ósseos alógenos, xenógenos e aloplásticos. Ainda existe a regeneração óssea guiada, distração osteogênica, fatores de crescimento e as combinações destas referidas metodologias. Dentre os materiais disponíveis, o osso autógeno é tido como primeira opção para a reconstrução óssea,tido como padrão ouro em enxertia óssea, pois fornece as condições mais favoráveis de reparo pós-cirúrgico, por apresentar as propriedades de osteocondução, osteoindução e osteogênese,auxiliando na correção de defeitos de espessura, desde que haja um bom suprimento vascular no local. Neste trabalho é demonstrada uma técnica de enxertia óssea em bloco autógeno, através da realização de um caso clínico, para a reconstrução de maxila atrófica, visando o aumento do volume ósseo disponível para a instalação de implantes dentais.


The installation of implants in areas of bone loss may be associated with an unfavorable ratiocrown-implant, unsatisfactory aesthetic result and cleaning difficulties, impairing treatment prognosis. The bone graft allows the installation of implants in a favorable three-dimensional position. Some methods have been studied and proposed for the reconstruction of lost alveolar bone: autogenous bone grafts, homogeneous bone, allogenic, xenogenous and alloplasticbone substitutes. There is still the guided bone regeneration, distraction osteogenesis, growth factors and combinations of these referred methodologies. Among the materials available, the autogenous bone is considered as the first option for bone reconstruction, considered the gold standard in bone grafting because it provides the most favorable conditions for post-surgical repair, presenting the properties of osteoconductive, osteoinductive and osteogenesis, helping the correction of the defects of thickness, since there is a good blood supply in the area. Thiswork shows a bone grafting technique in autogenous block by performing a case for the reconstruction of atrophic maxilla, in order to increase bone volume available for the installation of dental implants.

ABSTRACT

Although bone allografts are being widely used in dentistry, many of clinicians appear to be unfamiliar with their preparation and processing as well as their use as safe and effective graft materials. The major concerns associated with these materials are antigenicity and risk of disease transmission from donor to recipient. To minimize this risk, the production of an allograft worthy of distribution and implantation requires strict attention to detail through a comprehensive process. With an increasing clinical requirement for bone grafting procedures, there is a commensurate increase in patients' demands for assurance that bank bone will not be infected with pathogens. To ensure the patients, dental surgeons should be able to cite factual information and recommendations by responsible organizations regarding safety of allografts. Knowledge of human bone allograft procurement, processing, and tracking may allow dentists to better educate patients and address concerns about this valuable treatment option. The purpose of this review is to furnish and update the current knowledge on processing, safety, and efficacy of allograft materials.

ABSTRACT

Este estudo de reflexão traça algumas considerações acerca da existência e funcionamento de Banco de Ossos tendo por base a legislação existente no país e a literatura disponível. Destaca aspectos inquietantes relacionados à adequação ética e legal dos serviços às normas que dispõem sobre a realização de transplantes ósseos, bem como da participação do enfermeiro na organização e funcionamento de serviços que executam os procedimentos de captação, processamento, estocagem e distribuição dos tecidos ósseos utilizados em enxertos.

ABSTRACT

Bone grafts are necessary to provide support, fill voids, and enhance biologic repair of skeletal defects. They are used by orthopaedic surgeons, neurosurgeons, craniofacial surgeons, and periodontists. Bone harvested from donor sites is the gold standard for this procedure. It is well documented that there are limitations and complications from the use of autograft, including the limited quantity and associated chronic donor site pain. Despite the increase in the number of procedures that require bone grafts, there has not been a single ideal bone graft substitute Scientists, surgeons, and medical companies, thus, have a tremendous responsibility to develop biologic alternatives that will enhance the functional capabilities of the bone graft substitute, and potentially reduce or eliminate the need for autograft. This article is an attempt to review the past and existing bone graft substitutes, and future directions of research. The historical data was extracted after thorough review of the literature. The data for the current concepts and future directions was compiled from the Internet, and from direct correspondence with medical companies. Since many products are undergoing clinical trials, and are yet not commercially available, their data cannot be found in literature. The main purpose of this article is to give the reader an idea about the existing market products and products likely to be available in near future.

ABSTRACT

Foram comparados seis métodos de preservaçäo de aloenxertos ósseos. A autoclavagem desnaturou proteínas e interferiu na incorporaçäo após o implante. A glicerina 98 por cento näo foi efetiva na esterilizaçäo do osso e alterou suas propriedades biomecânicas. A refrigeraçäo e o merthiolate näo mantiveram o osso sem contaminantes e os enxertos falharam. O osso preservado sob congelamento em soluçäo fisiológica e antibiótico permaneceu estéril, sua integridade física foi preservada e näo falhou na enxertia.

ABSTRACT

Los bancos de tejidos representan uno de los horizontes mas amplios de la ortopedia actual. El inicio logico de estos debe ser el proceso y almacenamiento de hueso por ser esta tecnica la mas util y a su vez la mas simple. En el Hospital Universitario del Valle iniciamos el banco de tejidos en Octubre de 1985, logrando realizarse el primer trasplante en Diciembre de 1986, habiedose beneficiado hasta el momento un total de treinta pacientes. En este trabajo revisamos los aspectos basicos del trasplante de huesos, terminologia, histologia, tecnicas y finalmente presentamos la tecnica que veniamos empleando para el proceso de huesos y tejidos donados a nuestro banco.
