Introduction: We report a clinical and radiological evaluation and analysis with SEM of 5 clinical cases of augmentation of the maxillary sinus (unilateral and bilateral) with autogenous bone graft harvested of the illiac crest and mandibular symphysis. Material and method: We carried out a retrospective study in 5 patients (2 males and 3 females) with a follow-up at first month, sixth month and first year after bone transplantation, and evaluated clinical and radiological parameters. This study was completed with an histological analysis of the bone graft using SEM. Results: The bone graft was successful, allowing the implant treatment. However, there have been variable symptoms depending on the patients, being the inflammation and the pain the more frequent symptoms. The resorption of the bone graft was maintained with levels lower than 30%, being lesser in the bone graft harvested of the symphysis. Histologically, the mechanism of the formation and remodelation of the new bone were carried out satisfactorily. Conclusions: The augmentation of the maxillary sinus with autogenous bone graft is a feasible treatment that allows the placement of implants in patients with atrophy in the posterior part of the maxilla.
