Abstract(s)
A reabilitação da maxila posterior através de implantes apresenta vários obstáculos, nomeadamente pouca altura óssea residual, pneumatização do seio maxilar e baixa densidade óssea. Implantes de menor comprimento foram desenvolvidos a fim de dar solução a estas situações. Para compensar as reduzidas dimensões, melhoras na macro e microgeometria se fizeram necessárias. O objetivo deste trabalho foi verificar a viabilidade do uso de implantes ultra curtos (≤ 6,5 mm) na zona posterior maxilar. Foi realizada uma revisão bibliográfica de dados recentes da literatura a respeito de fatores mecânicos, biológicos, protéticos e taxas de sucesso. Os implantes ultra curtos podem ser utilizados como uma alternativa às cirurgias de aumento ósseo associadas a implantes longos, com desfechos semelhantes. Estes representam uma opção minimamente invasiva, com menores custos e tempo global de tratamento, para além de menor morbilidade. Porém, ainda há poucos dados de acompanhamento a longo prazo.
Rehabilitation of the posterior maxilla with implants presents many obstacles, namely low residual bone height, pneumatization of the maxillary sinus and low bone density. Implants of shorter length have been designed to solve these situations. In order to compensate reduced dimensions, improvements in macro and microgeometry became necessary. The objective of this study was to verify the feasibility of using ultra short implants (≤6.5 mm) in the posterior maxillary zone. A bibliographic review of recent literature data on mechanical, biological, prosthetic and success factors was carried out. Ultra short implants can be used as an alternative to bone augmentation surgeries associated with long implants with similar outcomes. These represent a minimally invasive option, with lower costs and overall treatment time, in addition to lower morbidity. However, there are still few long-term follow-up data.
