Exposed Subperiosteal Framework
69 year old healthy female with exposed subperiosteal framework biaterally distally. Asymptomatic. CBCT appears to show osseous voids under the framework. The framework appears to be supported by 3 root form implants on the L side. One of these penetrates the nasal cavity. The root from implant on the R side is a sleeper. The hybrid denture is retained by locator abutments. She is presently on Periostat 20 mg BID as a precaution. I have no experience with subperiosteal prosthesis. What is appropriate treatment here? Thank you for your direction.
