The alveolar atrophy of superior maxilla is a difficult challenge to resolve in clinical practice for the dental rehabilitation on implants. There are several methods of reconstruction with this purpose.
Although the election of the method depends on several factors, most importantly the amount of bone surplus and the patient ́s desires. We presented/displayed two cases in which we have carried out the prosthodontist rehabilitation on MG Osseous implants, non removable in one and removable in the other case. Previous to the positioning of the implants alveolar reconstruction was carried out with calvarial bone graft.
