This study looks at the long-term results of using overdentures (a type of denture that snaps onto implants) in the lower jaw of people with Type 2 Diabetes. People with high blood sugar, or chronic hyperglycemia, often have issues with their gums and bones around teeth and implants. This occurs because high blood sugar increases certain products in the body that cause inflammation and bone loss. But, with good blood sugar control, implants can work well over time. The study focuses on those with loose lower dentures and specific bone measurements, but not on those with a good handle on their diabetes, or who have bad habits like smoking heavily.

• Participants will have 4 implants placed in the lower jaw.
• Those with strong diabetic control or certain past treatments are not eligible.
• This study involves regular dental visits to check progress over time.
