A study of fracture loading test of cracked teeth with Ni-Ti memorial alloy
Abstract：AIM：To test fracture loading of extracted imitating teeth withNi-Ti memorial alloy(SMA). METHODS: All the extracted first low molars were divided into two groups(A,B). Group A was the control group while group B was the test group. Each contains 20 teeth. All the teeth were prepared into imitating cracked teeth. And those of group B were strengthened with SMA. The fracture loading test was performed on both groups after filling all the teeth with composite resin. RESULTS: The force of anti-fracture of extracted imitating cracked teeth with SMA(group B) was obviously higher than that of the teeth without SMA(group A). CONCLUSION: The test supplied scientific mechanism of using SMA to prevent further crack of teeth in clinic.
