    Abstract:
    The case of a patient with high-flow arteriovenous malformations (AVMs) affecting the mandible and lower face is presented. The patient had undergone surgical resection, sclerotherapy, and transcatheter embolization over the course of 16 years. As a result, all teeth except for the lower left third molar were missing, and a mass of arteriovenous malformed soft tissue covered the residual alveolar ridge. Implant placement surgery was performed in his mandible after treatment of the AVMs. Osseointegration of the implants placed in the mandible affected by the AVMs was evaluated. Rehabilitation in the absence of the alveolar ridge or keratinized gingiva was also evaluated. The implant stability quotient (ISQ) was measured before fabricating the restoration. An implant-supported partial denture was placed 4 months postoperatively. No implant failure was found; no bleeding on probing was present. The occlusion and masticatory function were satisfactory at 2-year follow-up. Osseointegration was safely achieved in the bone affected by the intraosseous AVMs that had been embolized. The success of an implant support prosthesis depends not only on the condition of the bony tissue but also on the surrounding soft tissue.
