Mandibular arteriovenous malformations are rare congenital malformations that require multidisciplinary care. Implant-supported rehabilitation of significant bone defect after embolization and resection is poorly described in the literature. We present the case of a 24-year-old patient with a right-sided mandibular arteriovenous malformation diagnosed after massive hemorrhage and treated by embolization and resection surgery. Implant rehabilitation was carried out 9 years later with a prior bone graft through iliac extraction and 3 short implants. Implant survival rate and patient satisfaction were evaluated at 3 years postplacement. Arteriovenous malformations treatments frequently result in bone defects that are difficult to reconstruct because of probable unstable vascularization due to embolization. The presence of osteosynthesis material and artifacts at the radiological level complicates implant planning due to the lack of visualization of the inferior alveolar nerve or artery and necessitates the placement of low-height implants. Osteointegration in contact with embolization products should be monitored. The creation of a case series could be of interest in order to better understand implant treatment for patients with a history of arteriovenous malformations.
