Abstract:
The posterior sector of the maxilla consists of an extremely thin facial lamina, with the underlying trabecular bone having a low mineral content. The loss of maxillary posterior teeth is a typical bone resorption pattern that implies a decrease in the bone width available at the expense of the labial plate.1 This is the explanation why the width in the posterior sector of the maxilla decreases at a faster rate compared to other regions.2 It should also be noted that the lack of vascularisation accelerates the phenomenon of bone resorption and initial Class D3 or D4 trabecular bone. Even if it decreases by 60%, however, the residual ridge is wide enough in the posterior maxilla for root-form implants. Progressive resorption shifts the alveolar crest towards the palate at the expense of bone width.3 The posterior maxilla continues to atrophy until the entire alveolus is ablated to basal bone. The vestibular cusp of definitive prosthetic rehabilitation must result from a balance between aesthetic requirements, biomechanical conditions, and bone availability in moderate to severe atrophic crests.4

Aumentos Ósseos em Implantodontia – Capítulo 15
A filosofia de tratamento do nosso grupo é totalmente favorável à realização de reconstruções teciduais (tanto óssea quanto tecido mole), para posterior reabilitação implantossuportada dos pacientes com atrofia severa nos maxilares. No entanto, entendemos que o implantodontista deve conhecer e estar apto a praticar (ou pelo menos a diagnosticar e encaminhar) alternativas de tratamento que também podem beneficiar o paciente.
Aumentos Ósseos em Implantodontia – Capítulo 11
A forma tradicional/clássica de tratamento dos rebordos atróficos é por meio do uso de blocos ósseos autógenos, através dos quais é possível obter bons resultados. No entanto, essa modalidade de tratamento é associada a um maior índice de exposição do enxerto ao meio bucal (principalmente nos caos de defeitos verticais), dificuldade de adaptação do enxerto ao leito recetor (em casos de rebordos irregulares), maior morbidade e maior dificuldade no posicionamento/fixação desses blocos ao nível da crista óssea, o que por vezes não proporciona um resultado homogéneo do rebordo, dificultando a implantação.
