title: Professional hygiene care, adjustments and complications of mandibular implant-retained overdentures: a three-year retrospective study.
abstract: OBJECTIVE
  This report presents a retrospective evaluation of postinsertion care required by 104 edentulous patients with advanced mandibular bone loss.
  
  
  METHODS
  The patients were treated with new maxillary dentures and mandibular overdentures retained by two implants with a single bar-clip attachment. Distinction was made between professional hygiene care, adjustments, and treatment of complications. The follow-up period after insertion of dentures was 3 years for all patients.
  
  
  RESULTS
  Approximately a third of the patients needed professional hygiene care. The need for adjustments declined during the years of function. Complications were encountered in approximately a third of the patients. The majority of these were not related to the implants, but to the superstructure and both the maxillary and mandibular dentures.
  
  
  CONCLUSIONS
  Many edentulous patients with advanced mandibular bone loss who were treated with mandibular implant-retained overdentures need professional hygiene care, adjustments, and treatment of complications.
