Aim and objective: This technique aims to improve the outcome of silicone finger prostheses by reducing voids and the risk of tearing. Background: Obtaining an intact porosity-free silicone finger prosthesis is a difficult task owing to the high viscosity of the material, coupled with difficult packing and retrieval in the thin ventral part of the mold (which is overlapped by the stump model). Technique: This technique describes predictable packing of silicone along with easier retrieval of prosthesis and mold. Incorporation of brass dowel pins in the stump model just before investment and packing of mold helps in preventing mold/stump fracture and tearing of silicone finger prosthesis. Conclusion: The described technique helps in creating a silicone finger prosthesis with fewer porosities, which can be easily extricated from the mold, thereby also increasing the longevity of the mold.
