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.
