Abstract(s)
A reabilitação oral com implantes dentários é uma solução terapêutica previsível frequentemente limitada por perdas ósseas decorrentes da reabsorção óssea pós-extração. Para superar estas deficiências, as técnicas de regeneração óssea alveolar desempenham um papel fundamental, permitindo a recuperação de volume ósseo adequado para a colocação de implantes. O aumento da crista óssea, tanto na dimensão vertical quanto horizontal, foi amplamente estudado. Diversos estudos demonstraram que as intervenções de aumento vertical podem alcançar resultados consistentes, enquanto outros destacam a previsibilidade da regeneração óssea guiada em aumentos horizontais.
No contexto dos enxertos ósseos, estudos comparam enxertos autólogo e alogénicos, mostrando que ambos são eficazes no tratamento de defeitos alveolares, mas com características especificas que influenciam a sua escolha clinica. Por outro lado, a elevação do seio maxilar continua a ser uma técnica essencial para a regeneração em áreas posteriores do maxilar superior. Vários estudos confirmaram a eficácia e segurança da técnica transcrestal de elevação do seio maxilar em casos de reabsorção óssea severa.
Esta revisão narrativa tem como propósito analisar e comparar diferentes abordagens regenerativas, incluindo enxertos ósseos e técnicas cirúrgicas, com base na evidência disponível, para determinar a melhor estratégia na criação de leitos ósseos adequados antes de colocarmos implantes dentários.
Oral rehabilitation with dental implantsis a predictable therapeutic solution that is often limited by bone loss resulting from post-extraction bone resorption. To overcome these deficiencies, alveolar bone regeneration techniques play a fundamental role, enabling the recovery of adequate bone volume for implant placement. Ridge augmentation, both in vertical and horizontal dimensions, has been extensively studied. Several studies have shown that vertical augmentation procedures can achieve consistente results, while others highlight the predictability of guided bone regeneration in horizontal augmentation. In the context of bone grafts, studies have compared autologus and allogeneic grafts, showing that both are effective in the treatment of alveolar defects, but with specific characteristics that influence their clinical selection. On the other hand, maxillary sinus lift remains an essential technique for regeneration in the posterior regions of the upper jaw. Multiple studies have confirmed the effectiveness and safety of the transcrestal sinus lift technique in cases of serve bone resorption. This narrative review aims to analyze and compare diferente regenerative approaches, including bone grafts and surgical techniques, based on the available evidence, in order to determine the best strategry for creatong suitable bone beds prior to dental implant placement.
