ABSTRACT
Atrophic maxilla rehabilitation has been the subject of several studies for decades; despite this, there are still manydifferent therapeutic choices for the best way to treat maxillary resorption in order to enable implant placementand integration. These possibilities include the optimal use of remaining bone structures, such as the pterygoidprocesses or zygomatic arch, which involves using zygomaticus and pterygoid implants in combination with standardimplants placed in the residual bone; alternatively, regenerative techniques, alveolar bone expansion/distractionor bone grafting techniques may be used. Severe maxillary atrophy has a multifactorial aetiology; the mostimportant factors being long evolution edentulism, hyperpneumatization of the maxillary sinus, post-traumaticdeficit, bone loss after surgery (tumours, cysts) and periodontal problems or infection. In this report, we present aclinical case of onlay block reconstruction in an atrophic maxilla with harvested cranial calvarium bone grafts forsuccessful future implant-supported oral rehabilitation (AU)
