Mandibule rehabilitation after embolization of hemangioma with implant overdenture using existing endosseous implants: A clinical report.

PATIENT: A fifty-year-old man received embolization for mandibular hemangioma two years ago, and the surgeon had placed four implants in his mandible and made a removable denture upon the implants. His denture however fractured repeatedly in the past years. After examination and communication with the patient, an implant-assisted overdenture incorporating bar attachment combined ERA attachment and Locator abutment was re-fabricated. A sixteen months follow-up showed acceptable outcome.

DISCUSSION: There are some guidelines on design of implant over-denture, the site of implant will affect the final result. The unfavorable bone structure of mandibular hemangioma restricts the number and the site of implant, modification of design is essential to improve the final result.

CONCLUSION: Multi-disciplinary cooperation should be established for extensive edentulous case. Overlay type prosthesis incorporating several types of attachments can be suitable for complex case because of acceptable results and easy maintenance.
