The Use of CAD/CAM Trial Pattern for Facial Prosthesis Fabrication of a Maxillofacial Patient with Large Defect

Nina Ariani, Yenny Pragustine

Abstract


Treatment of maxillofacial patients needs a multidisciplinary approach of several expertise based on the complexity
of the case. Prosthodontists often work together with e.g. ENT, oral or plastic surgeons to provide patient with better
prosthesis and optimum treatment. Case report: A 55 years old male was referred to Dental Teaching Hospital of
Universitas Indonesia for facial prosthesis fabrication. Patient had undergone squamous cell carcinoma ablation
surgery that encompassed nose, cheek, sinuses, upper lip and most of the hard palate. Due to the extensive nature
of the defect, Department of Prosthodontics collaborated with Department of Biomedical Engineering to employ
3D printing technique using general purpose machine for fabricating the trial pattern for the prosthesis, with
attention given especially to margin areas and facial contours. This technique helps for prosthesis fabrication of
this patient because manual wax carving is no longer necessary. Wax carving usually is a labor/skill intensive step
and takes longer time. Conclusion: 3D printing of the trial pattern for the prosthesis help minimizes the labor/
skill intensive part of facial prosthesis fabrication.
