Introdução: A atrofia óssea vertical da região posterior da mandíbula é um problema comum que o Médico Dentista enfrenta diariamente, o que dificulta a colocação de implantes dentários para a reabilitação de zonas edêntulas. Nesta revisão bibliográfica serão abordadas quais as etiologias e a dinâmica da reabsorção óssea na mandíbula atrófica posterior, analisando técnicas cirúrgicas que têm como princípio regenerar o osso no sentido vertical, com o uso de enxertos e membranas para restabelecer a quantidade adequada de volume ósseo onde os implantes dentários serão posteriormente inseridos. Especificamente são descritas as técnicas de Inlay Bone Graft, Onlay Bone Graft e Guided Bone Regeneration, comparadas na eficácia/confiabilidade da quantidade de aumento da crista vertical, sobrevivência e taxa de sucesso do implante, reabsorção óssea vertical após a cirurgia e complicações biológicas devido aos procedimentos cirúrgicos acima mencionados. Também são propostos critérios de decisão que podem auxiliar o cirurgião no tratamento de atrofias ósseas verticais na mandíbula.
Introduction: Vertical bone atrophy of the posterior mandible is a common problem that the dentist has to face daily, making it difficult to insert dental implants for the rehabilitation of missing teeth. This bibliographic review will begin by explaining the etiologies and dynamics of bone resorption in the posterior atrophic mandibles, then analizing the surgical techniques that have as a principle that of regenerating the bone in the vertical direction, with the use of grafts and membranes, to restore the adequate amount of bone volume where later dental implants will be inserted. Specifically, inlay bone graft, onlay bone graft and guided bone regeneration techniques are described and compared on the efficacy / reliability of the amount of vertical ridge augmentation, implant survival and success rate, vertical bone resorption after surgery and biological complications due to aforementioned surgical procedures. Decision criteria are also proposed that can aid the surgeon in the treatment of vertical bone atrophies in the posterior mandible.
