Introduction Patterns for somatoprostheses are conventionally made of modeling wax.

The rigidity, brittle nature, reduced edge strength, and susceptibility to distortion of this wax often leads to failure in achieving marginal thinning and desired aesthetics.

Technique A technique for fabrication of digital somatoprosthetic wax patterns with thin accurate margin by incorporation of a vacuum-formed polyvinyl chloride (PVC) template is described.

Results and Discussion The technique helps in overcoming limitations of an all-wax pattern and improves accuracy and aesthetics of outcomes.

Conclusions Incorporation of a PVC template in a somatoprosthetic wax pattern is a valuable technique to achieve good aesthetics and accuracy with the prosthesis.
