Abstract
In medical and surgery applications, the implant design is the key. Any mismatch in the implant design results in the implant failure as well as psychological stress and pain to the patient. Measuring and inspecting the geometrical implant design with the reference model is very important, to ensure the proper fitting and safety of the patient. The purpose of this study is to perform the evaluation between two geometrical custom implant design techniques-mirroring and anatomical design, commonly used in the reconstruction of the mandible implants. The results of the three-dimensional (3D) deviation analyses demonstrate that the average deviation of the anatomical design model is in the range of -0.0841 to 0.1167 mm which is less compared to mirroring technique model with a range of -0.4456 to 0.4322 mm. The two dimensional (2D) geometrical surface deviation illustrates that the mirror reconstruction technique has more deviation (2.05 mm) from the reference mandible model when compared to the anatomical reconstruction technique (1.22 mm).
