The rehabilitation of atrophic maxilla is still presented today as an anatomical/physiological challenge for professionals in the dental field who aim to seek the installation of implants for future prosthetic rehabilitations, in view of the degree of difficulty in reconstituting the lost alveolar ridge. In order to rehabilitate these jaws in the face of adversity, different techniques are proposed such as autogenous, homogenous bone grafts, allogeneic, xenogenous and alloplastic bone substitutes and their respective techniques. The aim of this study was to present a clinical case report, in which two hemi-arch alveolar ridge reconstruction techniques were performed in the same maxilla using biomaterial en bloc, in order to compare the histological and clinical results. After 5 months of grafting, material was collected from the alveolar grafts bilaterally using trephine burs for histological study. Through the used methodology, it was possible to see greater bone formation of structure on the side in which the dental cell transplantation (TCO) methodology was practiced, which advocates the association of mandibular medullary blood to the biomaterial, in relation to the contralateral technique in which the methodology was used conventional method, which advocates the association with peripheral blood biomaterial. It can be observed through the used methodology that the use of biomaterials potentiated with mandibular medullary blood showed greater growth of bone structure, increasing around 35% more in the neoformation of vital bone.
