Teeth protecting and straightening tool


PURPOSE: To offer a teeth protecting and straightening tool which can easily be handled by using poly ε-caprolactone to form the tool. CONSTITUTION: Poly ε-caprolactone used as a teeth protecting and straightening tool has a softening temperature of less than 100°C and can be softened when put in boiled water. The poly ε-caprolactone is excellent in fluidity and can easily be deformed when bitten by teeth to fit the arrangement of the teeth of each individual, since plenty of time is taken before the tool is hardened after heating and softening. Also the tool is easily handled since there is no necessity of biting the tool while it is hot. COPYRIGHT: (C)1991,JPO&Japio
