[Retention and rehabilitation of complex maxillofacial defects based on bar-clip and stud attachment].

Purpose: 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.

Conclusion: Application of precise attachment in complicated maxillofacial defects can get satisfactory result.
