title: [Case report of partial denture using Dimple-bar telescopic system].
abstract: METHODS
  A 49-year-old female patient presented to Prosthodontic Clinic at Nihon University School of Dentistry at Matsudo with the chief complaints of chewing difficulty and poor appearance. She was diagnosed moderate to severe periodontitis and partially edentulous dentition on both maxilla and mandible. Occlusal reconstruction was conducted with crown restorations and removable partial dentures (RPD). From the esthetic request of patient, Dimple-bar telescopic (DBT) system was applied to the mandible with bilateral distal coping abutments.
  
  
  CONCLUSIONS
  DBT system has been functioning well for more than 5 years without abutment tooth loss. It was thought that bilateral distal coping abutments can help to resolve problem with bilateral distal extension RPD dilemma.
  
  
  CONCLUSIONS
  It is suggested that DBT system has great potential to resolving weak points of clasps, such as low retentive forces and/or esthetic problem. Furthermore, author got a new understanding of the importance of maintenances.
