Anatomy models using Silicone Moulds - An innovative meth

Introduction: Neuroanatomy specimens like cerebrum, cerebellum, brain stem, etc. when taken out of preservation solution dries up and becomes discoloured within a short span of time. These specimens are easily damaged when used repeatedly and become unfit for teaching. The models of these specimen made with silicone using silicone moulds are similar to the original specimens with excellent surface detailing.Using silicone moulds, models like vertebrae using resin also can be made. Materials and methods : The silicone material used in our study is Moldsil P. For making a silicone mould, an acrylic jar is made, which is little bigger than the specimen. Moldsil P is mixed with hardner and poured into the container so that it fills half the volume of the jar. The specimen is immersed into the silicone in such a way that only its upper half is exposed. After the silicone is hardened, the rest of the specimen is covered with the silicone mixture [Moldsil P+hardener] and allowed to dry. The specimen is taken out and the cavity of the impression is filled with silicone or resin to make a cast. Results & Conclusion: The silicone models of neuroanatomy specimens made using silicone moulds are soft, easy to handle and are exactly similar to the specimens. These are used as an alternative teaching aid. Silicone moulds can be used for taking resin cast of vertebra
