It is a kind of that for generating, to be used for the system of PSI mold formers that implantation material is overhauled include: benchmark anchoring surface identification module, it is configured to from least one benchmark anchoring surface of the specific image recognition of at least one patient of implantation material that is bone and being implanted into, which is configured to receive guidance benchmark (s). Implantation material abutment surface determining module determines implantation material abutment surface by the specific bone image of patient. PSI benchmark mold former generator blocks produce and export benchmark mold former using the benchmark anchoring surface and identified implantation material abutment surface identified, the benchmark mold former includes: contact surface, it corresponds to identified implantation material abutment surface, for connection complementary with identified implantation material abutment surface Boundarys socket part point is guided, is configured to guide the placement of the guidance benchmark in benchmark anchoring surface And it is located at contact surface and guides the specific geometry of patient between boundarys socket part point.
