Extending Application of Computer-aided Manufacturing for Development of Microtia Grade III Prosthesis – A Case Study

Jignesh D. Jani, Siddharth Jhala, Deepika Mor and Amit V. Sata

Abstract

Contributions of various engineering fundamentals in collaboration with medical science for making human life better are increasing exponentially in recent times. In this work, a collaborative team of professionals from engineering as well as medicine has jointly developed a prosthesis for microtia grade III using fundamentals of computer-aided manufacturing at a very affordable cost as well as within a considerably short duration. A young girl has a deficiency related to microtia grade III in her left ear. To develop a prosthesis related to her left ear, a quick-setting gypsum replica of her right ear has been initially developed. This gypsum mold is usually scanned using a CT scan to create 3D model for further processing by medical practitioners. This technique usually increases the cost of scanning. Here, a 3D structured light scanning technique is employed to create a 3D model from gypsum mold. The proposed technique has provided results with accuracy comparable with the CT scan at a very affordable cost. The three-dimensional model of the right ear was then mirrored to create a model of the left ear using a solid modeling tool. The mirrored three-dimensional model was then transformed into a format suitable for 3D printing. The 3D model of the right ear was then created using Fused Deposition Modeling based on 3D printing and implanted followed by minor processing. Here, collaborative efforts of engineering with medicine increase the possibility of the development of prostheses related to microtia grade III within a very affordable cost and time frame.
