One method of reinforcing denture base material is to use fiber composite reinforcement. Different types of fibers, such as glass (GF), carbon/graphite, aramid, and ultrahigh-modulus polyethylene (UHMP) fibers have been tested for this purpose.
This article reviews the studies conducted on the fiber-reinforced denture base resin systems.
The literature has reported that the fiber concentration and its adhesion to polymer matrix influences the transverse strength of the fiber composite. The highest transverse strength value (265 MPa) with polymethyl methacrylate (PMMA) was obtained by incorporating 58 wt% GF into the resin. UHMP fibers incorporated into PMMA resin yielded the highest impact strength value (134 kJm-2) of the fiber-PMMA composites.
Despite the improved mechanical properties of fiber-reinforced denture materials, further research is required to show the clinical usefulness of the fiber reinforcement.
增强义齿基托材料的一种方法是使用纤维复合材料增强。为此已测试了不同类型的纤维，如玻璃纤维（GF）、碳/石墨纤维、芳纶纤维和超高模量聚乙烯（UHMP）纤维。
本文综述了对纤维增强义齿基托树脂系统所进行的研究。
文献报道纤维浓度及其与聚合物基体的黏附力会影响纤维复合材料的横向强度。通过在树脂中加入58 wt%的玻璃纤维，聚甲基丙烯酸甲酯（PMMA）获得了最高横向强度值（265 MPa）。掺入PMMA树脂中的UHMP纤维产生了纤维 - PMMA复合材料的最高冲击强度值（134 kJm-2）。
尽管纤维增强义齿材料的机械性能有所改善，但仍需要进一步研究以证明纤维增强在临床上的实用性。
