3-D Photoelastic of Teeth-jaw and Its Clinical Practice
“夹部牙”光弹实验及临床应用

Method of making 3-dimensional photoelastis model of teeth-jaw is proposed. It shows that such a model is adequate for stress analysis.A new type of teeth the partially re- movable teeth of clamped dental plate(PRTCP)-is also introduced.Its design has been shown to be reasonable in clinical practice and photoelastic experiments.
