Midline fractures appear to be the most common problem in maxillary complete dentures, and they can be prevented by reinforcement of the base material. In this clinical trial, complete upper dentures made, for patients having a history of midline fractures, that were reinforced with ultra-high modulus polyethylene fiber in woven form. This fiber was treated with a silane-coupling agent and sandwiched between acrylic dough. Laboratory procedures were conducted easily and conventionally, without any special equipment. At the end of 18 months, all of the dentures were well accepted and did not show any signs of fracture.
中线骨折似乎是上颌全口义齿最常见的问题，通过增强基托材料可以预防。在这项临床试验中，为有中线骨折病史的患者制作了用上高模量聚乙烯纤维编织物增强的上颌全口义齿。这种纤维用硅烷偶联剂处理后夹在丙烯酸面团之间。实验室操作简便且常规，无需任何特殊设备。18个月结束时，所有义齿都被很好地接受，且未显示出任何骨折迹象。
