Treatment with mandibular bone-anchored implant bridges can solve long-term problems of prosthetic rehabilitations in totally or partially edentulous patients. However, a bone-anchored bridge creates a narrow and deep space between the base of the super-structure and alveolar ridge, and therefore, a patient's personal hygiene with a bone-anchored bridge is more difficult to perform than with an implant-supported overdenture. The aim of this study is to evaluate the oral hygiene status of patients with mandibular bone-anchored bridges, and to analyze their problems. From September 2000 to April 2004 in our hospital, 10 cases (5 males and 5 females; average age 48.9 years) with totally and partially edentulous mandibles were treated using implant-supported bone-anchored bridges with immediate or conventional loading. Oral hygiene instructions were given immediately after delivery of the superstructure, and follow-up examinations were provided for a period ranging from 9 months to 4 years and 5 months. The oral hygiene status of each patient was classified into one of 4 levels ("excellent", "good", "marginal" and "poor") at the follow-up observations. As a result, 1 patient (44 year-old female) was evaluated as "excellent", 2 (average age; 58.5 years) were "good", 5 (average age; 44.4 years) were "marginal" and 2 (average age; 53.0 years) were "poor". The ages of the patients with bone-anchored bridges were relatively young (26-70 years), and therefore, no observable tendency was recognized among different generations in the ability to perform oral hygiene. As a result, the patient's skill involved in cleaning and understanding the importance of oral hygiene was considered important for maintaining a healthy oral condition. We conclude that continuous professional oral hygiene care by dental hygienists is needed for patients with bone-anchored implant bridges.
