Management of a Zygomatic Implant Complication Using Custom-Made Subperiosteal Implants: A Case Report

Introduction: Zygomatic implants are effective for treating edentulism when conventional implants are unsuitable due to insufficient bone volume. Despite high success rates, complications such as sinusitis and osseointegration failure may occur. This report presents a case in which a custom subperiosteal implant was successfully used to manage a zygomatic implant complication. Case Presentation: A 52-year-old female with severe maxillary bone loss underwent zygomatic implant placement. Four months later, a complication with the right posterior zygomatic implant was identified, leading to its removal and the subsequent repair of an oroantral fistula. A custom subperiosteal implant was then successfully placed. Discussion: Complications with zygomatic implants require innovative solutions. Subperiosteal implants provide an effective management option, especially in cases involving severe bone loss. Conclusion: This case demonstrates the successful use of subperiosteal implants to manage zygomatic implant complications, underscoring the need for further research in this field.
