The acrylic resin denture base is used more than the usual metal denture base because of the low cost, simple process to make and easy rebasing. But, as the strength of the resin is weaker, the upper resin denture base is three to four times as thick as the metal denture base. So, a study was made to make the upper complete resin denture base thinner while maintaining the strength of the resin denture bases currently in use now. To make the palatal area of the denture base thinner was made possible by the application of carbon fiber (CF)-cloth reinforcement. The resin denture base reinforced by the CF-cloth was of a thickness of 0.7 mm and was evaluated for the mechanical properties of bending. As a result, it was found that both the stiffness and strength were improved by 10% or more as compared with those of the ordinary resin denture bases.
由于成本低、制作工艺简单且易于重衬，丙烯酸树脂义齿基托的使用比普通金属义齿基托更为广泛。但是，由于树脂的强度较弱，上颌树脂义齿基托的厚度是金属义齿基托的三到四倍。因此，开展了一项研究，旨在使上颌全树脂义齿基托变薄的同时保持目前使用的树脂义齿基托的强度。通过应用碳纤维（CF）布增强，使得义齿基托的腭部区域变薄成为可能。用CF布增强的树脂义齿基托厚度为0.7毫米，并对其弯曲力学性能进行了评估。结果发现，与普通树脂义齿基托相比，其刚度和强度均提高了10%以上。
