Technique to prevent fracture of a partial auricular prosthesis mold.

One of the difficulties faced during the essential and demanding step of fabricating a mold for a partial auricular prosthesis is the fracture of its most elevated part, which engages the remnant concha and triangular fossa region, because of the presence of excessive convolutions and undercuts. This technique describes a 4-part mold for a partial auricular prosthesis in which the most elevated portion is poured separately, thereby preventing mold fracture.
