In present study dried animal and human bones were used, since there are so many factors as medullary bleeding which hinder adhesion of bone in vivo. Using TOM/100E type universal strain gage, tensile and bending strength were determined in each material. Aron αA was employed, because it has a rapid set time and is simple in procedure. Prior to applying the adhesive it is the most difficult preparation to grind bone horizontally so as to obtain the complete contact between the both bony surfaces.
The results showed that the adhesive was relatively strong to tensile strength, but bending strength was extremely low which was less than 1/20 of tensile strength. If dimension of the bony surface becomes twice, the set time of the adhesive duplicates proportionally.
Chemical osteosynthesis is considered to have severe problem as weakness for bending strenghth.
