Subperiosteal implant overdenture fabrication using existing custom Dolder bar attachments

Endosseous root-form implants are the most popular type of implant used today. However, patients may present with subperiosteal implants that need treatment with a removable prosthesis. This case report describes the fabrication of a new set of overdentures for 30-year-old subperiosteal implants using the patient's current dentures as a guide to establish a proper vertical dimension of occlusion and occlusal scheme. In addition, the patient's older set of dentures was used as the record bases in an effort to reuse the existing custom Dolder bar attachments. Esthetics and lip support were enhanced by selecting new teeth and adjusting the tooth positions. The patient was pleased with the esthetic and functional results of the new overdentures.
