ABSTRACT
Introduction: placing a dental implant can be a challenge, especially in bone defects after tooth loss, trauma or agenesis that may make placement impossible. The autologous chin graft is an alternative in atrophic alveolar ridges, due to its osteogenic, osteoinductive, osteoconductive properties and easy access. Objective: to evaluate the volumetric changes of the bone tissue in the anterior area of the maxillary alveolar ridge. Presentation of cases: case 1: a 34-year-old female patient, with no medical history, attended for dental implant planning in the area of dental organ (DO) 12, clinically and imaging evidenced agenesis of DO 12 and horizontal bone deficiency, a chin block graft was performed and 5 months later, the placement of the dental implant. Case 2: a 30-year-old male patient, with a history of amelogenesis imperfecta, attended the Oral Surgery service of the Central University of Venezuela (UCV), for evaluation of atrophic alveolar ridge in DO 12 after trauma, a chin block graft was performed to reconstruct it and after 5 months, the placement of the dental implant. Results: in both cases, a chin graft was taken through a vestibular-mandibular approach, achieving a 2-5mm horizontal bone increase, the implant was satisfactorily placed, without complications during or after the surgical act, and there were no significant differences between the cases performed, either by age or gender. Conclusion: reconstruction with a chin block graft is a simple and predictable technique that allows optimal bone volumes to achieve ubication of dental implants in the anterior area.REFERENCES
