Abstract: In the process of rabbit bone specimens preparation, bleaching and cementing are very important steps which directly affect the overall quality and appearance of the specimens. In order to find out satisfied bleaching and cementing process for rabbit bone specimens, a total of 8 degreased rabbit bone samples were randomly divided into 4 groups and bleached with 5%, 15%, 25% and 30% hydrogen peroxide solutions, respectively. After bleaching, the rabbit bone samples were randomly divided into four groups of A, B, C and D. Using unmovable joints, semi-movable joints and movable joints as experimental subjects, the cementing effect of four adhesives, including bone glue adhesive, AB glue, 502 glue and hot melt adhesive, were observed and compared. The results showed that the hydrogen peroxide concentrations and treatment times required for bones in varied parts were different: skull was bleached in 30% hydrogen peroxide for 1.5 h, cervical vertebra, lumbar vertebra and sternum were bleached in 25% hydrogen peroxide for 1.5 h; costal bone, humerus and scapula were bleached in 15% hydrogen peroxide for 1.5 h; metacarpal bone, coccygeal vertebra and phalanx and some other bones were bleached in 5% hydrogen peroxide for 2 h. Furthermore, bone glue adhesive had quick effect, tight bonding, high strength, and good shaping effect. The bleaching and cementing process determined in this study can effectively reduce the damage to the rabbit bones during the specimens preparation, keep the original appearance of the bones to the greatest extent, and make the specimens more vivid.
