Summary
One of the greatest challenges in maxillofacial surgery is the reconstruction of maxillary bone defects for a subsequent functional rehabilitation of the stomatognathic system. The loss of bone tissue suffered by the maxillary bones may be of congenital origin such as palatal lip fissures or acquired, either as a result of a neoplasm or intra-cè˛e injury that causes a post-surgical defect, or trauma or toothlessness of the area (Kolerman et al.). The deficit of bone tissue suffered by the jaws, often prevents or hinders dental rehabilitation, needing to resort to surgical techniques that correct these defects, with bone grafts being the most widely used alternative today (Ramírez-Fernández et al.). According to origin, bone grafts are classified as: allografts, autografts, xenografts and bone substitutes (Chappard et al.). Multiple reconstruction techniques are described using bone grafts that depend on the magnitude of the defect, the availability of biomaterials and the patient's local and systemic conditions. Below is a series of 3 clinical cases that required alveolar bone reconstruction prior to implant installation for dental rehabilitation. Autologous tibia bone graft was used in the three patients, being treated by the maxillofacial surgery team at Hospital el Carmen Maipú, Santiago Chile. The first case corresponds to a 65-year-old female patient with severe maxillary atrophy due to loss of 1.4 / 2.4 / 2.5 teeth, with severe pneumatization of the bilateral maxillary sinus. The second case was a 30-year-old woman with a unilateral alveolar fissure, who did not receive an alveolar bone graft in the early stages. The third case was a 55-year-old female patient who presented a mandibular compound odontoma in relation to teeth 4.2 and 4.3. For all three cases, an autologous bone graft taken from the tibial bone was used according to the technique described by Catone et al. (1992) in order to carry out subsequent rehabilitation with dental implants. The objective of this report is to present the surgical technique used and make a brief review of its advantages, disadvantages and associated complications.
