Treatment with mandibular implant-supported overdentures can solve long-term problems in edentulous patients. However, Cune and colleagues^<8)> reported that in 36.5% of patients with mandibular implant-supported overdentures, oral hygiene was evaluated to be suboptimal, and den Dunnen and his coworkers^<10)> reported that approximately a third of the patients with implant-supported overdentures in the edentulous mandibles needed professional oral hygiene care. From April 2002 to April 2004, 12 cases with edentulous mandibles were treated using implant-supported overdentures with immediate loading in our hospital. Oral hygiene instruction was performed immediately after delivery of the overdenture, and follow-up examinations were provided for 7 months to 2.5 years. The oral hygiene status of these patients was classified into 4 levels ("excellent", "good", "marginal" and "poor") at the follow-up observations. As a result, 3 patients (average age; 58.3 years) were evaluated as "excellent", 3 (average age; 73.3 years) were "good", 4 (average age; 75.0 years) were "marginal" and 2 (average age; 54.5 years) were "poor". The younger patients tended to have better ability of oral self-care than the older patients. However, the 2 patients evaluated as "poor" were both in their 50's. We conclude that continuous professional oral hygiene care by dental hygienists is needed for implant-supported overdenture wearers.
