Objective To study mechanical characters of the willow splint , and investigate the scientif ic parameters for the splintMethods 80 pieces of willow splints were divided into four groups according to t he sites of their applicationT wo pieces were selected randomly from the groups of the anteriosplint , postero splint, medial splint and lateral splintThe changes of deflection wit h load and time w ere measured and the law of t he changes were analysedResults ( 1) relationship between stress and strain of the splint w as in line w ith Hu e# s law under given load limits( 2) curves of the splint did not coincide when t he load w as increased or decreased( 3) Deflection of the splint would increase w ith time under ident ical load conditionsConclusion T he willow splint is a ind of stic and elastic texture bodyIts mechanic character is unstable and a study of t he improvement of the splint w ith a new material seems to be necessary Key Words!
