Retainer and pontic of FRP frame for crown and bridge resin were constructed with two different prepregs, used glass cloth and roving as reinforcement. Rigidity and adaptability of the FRP frame and bonding strength of jointing of retainer and pontic were investigated. The glass content was about 50 wt% for both kinds of prepregs. Bonding strength and modulus of FRP plate reinforced with glass roving were about 1.5 times larger than that of the FRP plate reinforced with glass cloth. Bonding strength of FRP specimen constructed by curing the prepreg put on the FRP plate was about 3 kgf/mm2. However, the bonding strength of specimen constructed by curing simultaneously the two prepregs was about 12 kgf/mm2. Though discrepancy of the FRP frame to stone cast of abutment tooth was proportional to the length of pontic, that of the FRP frame with a 50 mm pontic was less than 0.05 mm.
用于冠桥树脂的FRP框架的固位体和桥体采用两种不同的预浸料制成，分别使用玻璃布和粗纱作为增强材料。研究了FRP框架的刚性和适应性以及固位体与桥体连接的粘结强度。两种预浸料的玻璃含量均约为50 wt%。用玻璃粗纱增强的FRP板的粘结强度和模量约为用玻璃布增强的FRP板的1.5倍。将预浸料放置在FRP板上固化制成的FRP试件的粘结强度约为3 kgf/mm2。然而，同时固化两种预浸料制成的试件的粘结强度约为12 kgf/mm2。尽管FRP框架与基牙石膏模型的差异与桥体长度成正比，但桥体长度为50 mm的FRP框架的差异小于0.05 mm。
