Resumo: Background: The evolution of maxillofacial surgery is clear. With advances in digital planning, surgical techniques, orthognathic surgery becomes increasingly safe, however, still a physiological factor that challenges the surgeon: bone repair. The success of orthognathic surgeries, in addition to planning and correct execution, depends on the repair process and for that it is essential to maintain stability between the bone bases, which becomes a challenge in large movements. The use of biomaterials in orthognathic surgeries is not recent, in the 70s they were already used as a way to promote stability of movements and over time, biomaterials are being improved also to accelerate the process of bone repair, decreasing the chances of pseudoarthrosis and non-union. Bio-Oss® Collagen is a combination of purified cancellous natural bone mineral granules (Bio-Oss®) and 10% collagen fibres in a block form and is sterilized by γ-irradiation. The collagen facilitates handling of the graft particles and acts to hold the Bio-Oss® Collagen at the desired place. The consistency of this material readily allows it to take the shape of the defect. Case Description: We herein reported two cases that used autogenous and Bio-Oss® Collagen in orthognathic surgeries to chin augmentation and pseudoarthrosis treatment after orthognathic surgery; and discussed their advantages and indications. Conclusions: Both cases demonstrate that, the use of osteotomy techniques and adequate osteosynthesis, associated with the grafts can minimize complications and promote less morbidity in the surgical procedure.
