PURPOSE
Previous studies disclosed the ability of a light-activated denture reline material to strengthen a particular denture base material. The present study investigated the ability of the reline material to strengthen denture base materials processed by other means.
MATERIALS AND METHODS
Four denture base materials were tested for flexural strength at proportional limit (FSpl) with or without being relined.
RESULTS
The reline material maintained the FSpl of the microwave-processed and the autopolymerizing denture base materials. It increased the FSpl of the heat-processed and the light-activated denture base materials.
CONCLUSION
the light-cured reline material increased the flexural strengths of the heat-processed and the light-activated denture base materials and maintained those of the microwave-processed and the autopolymerizing denture base materials.
目的
先前的研究揭示了一种光活化义齿重衬材料增强特定义齿基托材料的能力。本研究调查了该重衬材料增强通过其他方法加工的义齿基托材料的能力。
材料与方法
对四种义齿基托材料在有或没有重衬的情况下进行比例极限下的抗弯强度（FSpl）测试。
结果
该重衬材料保持了微波加工和自凝义齿基托材料的FSpl。它提高了热加工和光活化义齿基托材料的FSpl。
结论
光固化重衬材料提高了热加工和光活化义齿基托材料的抗弯强度，并保持了微波加工和自凝义齿基托材料的抗弯强度。
