Presentation of a clinical case characterized by an atrophic degeneration in the superior maxilla which is very common to observe in the daily routine and wants to demonstrate the excellent results achieved with bone regeneration procedures by using grafting material of a homologous derivation, in this case of a particulate type. In view of the results in here presented and of those achieved in more than 10 years of clinical experience with homologous material, it can be considered an excellent alternative to the autologous grating procedures; and this also thanks to the clinical and histologic behaviour that this material has previously showed in the orthopedic field. The simplicity of the surgical procedures, the reduced invasivity for the patient and the possibility for the clinician to regenerate even the smaller defects contestually to implants insertion, allow many clinicians to benefit of this technique in their own practices.
