title: [Retention and rehabilitation of complex maxillofacial defects based on bar-clip and stud attachment].
abstract: OBJECTIVE
  To evaluate the application of precise attachment in restoration of complicated maxillofacial defect.
  
  
  METHODS
  A framework with bar-clip and stud attachment was designed and fabricated. Maxillofacial prosthesis with this framework was applied to treat a patient with defects of nose, entire upper lip and the corresponding maxillofacial areas. The retention force was tested with Universal Testing Device.
  
  
  RESULTS
  After treatment, the patient got a better appearance, normal function of mastication and clear pronunciation. The dislodgement test showed the retention force was 40N.
  
  
  CONCLUSIONS
  Application of precise attachment in complicated maxillofacial defects can get satisfactory result.
