A preoperative CT scan was obtained to determine the exact size and shape of the defect (Figure 1(a)). The titanium alloy (TiAl6V4) was used to manufacture the prosthesis by implementing 3D printing via additive manufacturing method (Figures 1(b) and 1(c)).

The ideal marginal adaptability and contour are shown in Figure 2.
Four and a half years of follow-up. Note the perfect contour and healthy intact soft tissue at the age of 17.
