目的：探讨分层堆塑技术对Ａｒｔｇｌａｓｓ烤塑树脂机械性能的影响。方法：用ＭＴＳ－８８０型拉力试验机，测试经古莎光固化箱固化的古莎产Ａｒｔｇｌａｓｓ系列材料的牙颈部、牙体部和切端材料，以及三种材料经分层堆塑固化后各自的抗压强度和直径拉伸强度。结果：分层堆塑固化后的抗压强度明显小于牙体部及切端材料，而与牙颈部材料无显著差别；牙颈部材料的抗压强度明显小于相互之间无明显差别的牙体部及切端材料。分层堆塑固化后的直径拉伸强度明显大于三种材料各自的直径拉伸强度，牙颈部材料的直径拉伸强度明显小于牙体部和切端材料，后两者之间无显著差别；结论：分层堆塑技术使直径拉伸强度提高，可以使修复体的抗折裂能力增强；分层堆塑技术与Ａｔｇｌａｓｓ系列材料结合可以达到比较满意的临床修复效果。
Objective: To investigate the effect of layered plastic technology on the mechanical properties of Artglass bakelite resin. Methods: The cervical, dental part and incision materials of the Gusha artglass material cured by the Gusha photocurable box were tested with the MTS-880 Tensile Tester, and each of the three materials was cured by layering Compressive strength and diameter tensile strength. Results: The compressive strength of layered plastic was significantly lower than that of dental materials and incision materials, but no significant difference with the dental materials. The compressive strength of dental materials was significantly lower than that of dental materials without significant difference Department and cut the end of the material. The tensile strength after stratified plastic curing was significantly larger than that of the three materials. The tensile strength of dental materials was significantly less than that of dental materials and incision materials. There was no significant difference between the two. Conclusion: Layered plastic technology can increase the tensile strength of the diameter, which can enhance the ability of the prosthesis to resist fracture. The combination of layered plastic technology and Atglass series of materials can achieve satisfactory clinical rehabilitative effect.
