Easy, fast, and accurate method of 3-dimensional mirror plane creation for actual clinical users

The first thing to do before planning the surgical treatment of unilateral defects or the asymmetry of the facial area is probably establishing adequate mid-plane for comparison and analysis of the normal and affected side. In such cases, a mirror image can be useful to obtain customized and optimized mid-plane for specific individuals considering the degree of the defect and asymmetry. With the concept of the iterative closest point (ICP) algorithm, the surface-based registration of the initial structure and mirrored structure allow us to generate a mirror plane that bisects the mid planes of each structure. This mirror plane would improve the quality of pre-operative evaluation and provide an appropriate start point for the treatment plan with as few errors as possible. Hence, the aim of this article is to introduce a method to create a mirror plane that can be assisting in increasing the accuracy of evaluation and analysis so a precise treatment plan would follow consequently.
