A Simple Technique to Fabricate a Facial Moulage with a Prefabricated Acrylic Stock Tray: A Clinical Innovation

Abstract

An accurate facial moulage helps in understanding the orientation and proper position of the facial prosthesis relative to other facial landmarks even in the absence of the patient. To make impression for fabricating facial moulage previously described techniques in literature made use of elastomeric impression material, alginate, and dental plaster directly over the patient's face to obtain the moulage which have their own disadvantages. Taking these into consideration a novel clinical technique is described herein to fabricate an acrylic stock tray for making accurate impression and to support the impression material while setting and pouring.

A Simplified approach for fabrication of custom tray for Facial prosthesis

“…Various materials have also been given in past with which impression can be made [8]. Kusum, et al de ined an innovative technique of taking facial impression by fabricating a stock tray of acrylic and with hinge attachment for accurate impression taking [9]. Most of the facial defect's impression can be obtained by using the present described technique.…”

Monoscopic photogrammetry to obtain 3D models by a mobile device: A method for making facial prostheses

“…To make a facial prosthesis, an impression is required to record the anatomic area of the defect. Some impression materials have demonstrated high and accurate precision registering details of defects and the surrounding anatomy [ 18 – 21 ], but present other difficulties and limitations [ 22 , 23 ]. Some challenges are related to the technical sensitivity of the material, working time and setting time.…”
