title: [Case of prosthodontic treatment by overdenture with magnetic and bar attachments].
abstract: METHODS
  An implant prosthesis with O-ring attachments had been fabricated for edentulous mandible. The patient complained of decreasing retention of the denture and frequent loosening of implant abutments. In order to resolve these problems, an implant overdenture prosthesis with magnetic and bar attachments was planned.
  
  
  CONCLUSIONS
  The patient has been satisfied for 4 years and 9 months after treatment, and poor retention of the denture and loosening of implant abutments have not occurred. The reasons might be consistently good retention of the denture with magnetic attachments, proper load distribution by connecting implants and improved oral care of the patient.
  
  
  CONCLUSIONS
  Periodical recall and adequate oral care are necessary.
