Abstract: Objective　To make the structure of the skull become hard, make the holes, joints and pipes well preserved by using the epoxy resin AB glue to bury the surface of the posterior skull by horizontal and coronal incision, which was the most easily damaged.　Methods　Forty-eight skull specimens were randomly divided into 8 groups. Each group were immersed individually into the epoxy resin AB glue in the organic glass box at different times. When soaking, there were gas discharging from the inside of the specimen for about 1 min.When there was no obvious large bubble, hemostatic forceps was used to clamp the edge of the thick skull wall to take out the skull, and the skull was held for a while above the plexiglass box and was gently shaken. After the flow of glue on the skull surface was basically dry, the skull was placed horizontally on the silicone plate and left it standing for 24 h.    Results    High transparency of the specimens and smooth skull wall can help to identify clearly the specimen structure. The skeleton stress of the fragile parts significantly enhanced. The skeleton , which was easy to fall off, was more closely connected with the skull. There were no obvious blockage and agglomeration on the surface of embedded skull specimens within 60 min after full stirring.   Conclusions    At room temperature, the appropriate time for skull surface embedding was within 60 min after full mixing of epoxy resin AB glue. The skull specimen after surface embedding  can better solve the dilemmas of not being easily damaged and not being touched in the course of experimental teaching.
