Life masks made of latex rubber have many advantages over models composed of other materials, such as wax, plaster of paris and similar substances. Rubber models are unbreakable and unaltered by rough usage. Storage problems are simplified, as the models may be stacked high in small spaces without damage. Flexibility of reproduced features facilitates the preoperative planning of reconstructive surgical operations about the face. Mounting of these models is relatively simple and effective.
The construction of life masks of latex rubber in accordance with my technic necessitates a practical knowledge of moulage materials and of plaster of paris molds. The familiar method of constructing a plaster of paris mold directly from the subject's face has been discarded for several reasons, namely, premature separation of the rubber in the mold, due to the grease used as a separating medium on the face; loss of skin texture and detail; difficulty of modeling
