Clinical Report of Cases with Removal of Large Subperiosteal Implants

Abstract

From 2002 to 2007, three patients who had uncomfortable large subperiosteal implants were treated. These implants were made from titanium and fixed by screws, but had become infected and were accompanied with pain and swelling.
Case 1: 68-year-old female
Her edentulous mandible had been restored by a subperiosteal implant. She had severe pain when chewing and swelling around the implant. The implant was removed, and her edentulous jaws were restored by removable dentures.
Case 2: 67-year-old male
His edentulous maxilla had been restored by a subperiosteal implant. He had had pain and discomfort in the maxilla for a long time from implant placement. His implant was removed, the bone defect was reconstructed by a fibula bone flap, and 6 implants were placed in the maxilla, after which his dentition was restored by implant prostheses.
Case 3: 70-year-old female
Her edentulous maxilla had been restored by a subperiosteal implant. She had felt pain and discomfort after the surgery and it did not improve for 10 years. The implant was removed, and her maxilla was restored by a removable denture.
Subperiosteal implants must not be used for treatment of edentulous jaws.
