The key technique is to generate a GTR guide with hollow shell, which is utilized proliferate abutment bone in order to link dental crown, on a thin titanium plate. Due to small dimensions and thin structure of the product, the extrusion tolerance of the die is the main consideration. This study used Solid Works graphics software to construct 3D mold drawing and then imported to DYNAFORM finite element analysis software to process simulation. This project utilizes finite element analysis to reduce developing time for those dies. Then, the experiment of multi-stage drawing processes for the product is participated using a titanium sheet with thickness of 0.25mm. A second laser processing for drilling holes on the titanium plate is essentially required. The control parameters of laser processing method are carefully optimized by conducting various experimental trials.
