Purpose: Augmentation genioplasty corrects vertical chin deficiency. To stabilize the synthesis and to allow ossification, a biomaterial prop is necessary. Third molars are frequently removed during orthognathic surgery and provides good material used as autogenous grafts. Surgical Technique: This article describes the surgical technique of an augmentation genioplasty using a third molar as a prop biomaterial. Results are stable in time. This technique presents no risk of infection and is less invasive than other autogenous bone graft. Conclusions: third molar can be used as a prop biomaterial in augmentation genioplasty Address correspondence and reprint requests to Dr Adeline Kerbrat, Hopital Pitié Salpétrière, Service de Stomatologie et Chirurgie Maxillo-faciale, 81 Boulevard de l'hopital, 75013 Paris, France; E-mail: adelinekerbrat@hotmail.com Received 28 August, 2020 Accepted 4 December, 2020 The authors report no conflicts of interest. © 2021 by Mutaz B.
