Accuracy of face castings employing thermoplastic custom trays for facial molding|
Pavanello, Kaue Campos; Marafon, Priscila Galzo & Mattos, Beatriz Silva Câmara
Aim: To evaluate the dimensional stability of a new facial molding technique using thermoplastic
custom molding tray.
Methods: The designs established demarcation of facial anthropometrics
landmarks, making linear measurements with a digital caliper. Facial molding was carried out
using thermoplastic custom trays, constructing a facial plaster cast with the anthropometric landmarks
already transferred by measuring the linear dimensions on the plaster cast and statistical analysis.
Results: All linear measurements in the palpebral and labial regions presented statistically
significant distortions. Only one of the linear measurements from the orbital region did not
demonstrate any significant distortion. The nasal region presented the least amount of distortion.
Conclusions: Although statistically significant, distortions were due to the method of breathing
and were considered to be clinically irrelevant. The reduction in the working time, the comfort
provided to the patient and the dimensional accuracy of the plaster cast obtained by the facial
molding technique using custom perforated molding tray suggest that this technique should be
employed for making facial prostheses.
