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