丙烯酸义齿基托的加固仍然存在问题。丙烯酸修复体骨折在修复实践中很常见，但尚未得到可靠解决。本研究比较了 3D 鞋面模型中可拆卸完整传统假肢的丙烯酸基体对咀嚼力的抵抗力。40 个包含两种类型增强网的丙烯酸基础试样（20 个带玻璃纤维网（FIBER-FORCE ^® - Synca，Bio Composants Médicaux ^TM，Tullins，法国），20 个带金属网（DENTAURUM ^® -Ispringen，德国）），20使用传统的 PMMA 丙烯酸基料（LUCITONE 199 ^® -Dentsply Sirona，York，PA，USA），和 20 使用永久性软衬里材料 (MOLLOPLAST-B ^®-DETAX GmbH & Co. KG, Ettlingen, Germany) 进行了测试 - 总共 80 个样本。一半的标本是为低牙槽嵴制作的，一半是为高牙槽嵴制作的。使用方差分析和学生t 的单向分析对数据进行分析- 独立测试样本的测试。在高牙槽嵴组中，玻璃纤维网增强假体的抗断裂性最强，而在低牙槽嵴组中，非增强假体的咀嚼阻力最大。在高牙槽嵴组和低牙槽嵴组中，具有永久性软衬里材料的假体对骨折的抵抗力最低。结果表明，根据牙槽嵴的高度为每个临床病例选择正确的加固材料可能有助于预防假体骨折。

Comparison of the Masticatory Force (with 3D Models) of Complete Denture Base Acrylic Resins with Reline and Reinforcing Materials

The reinforcement of acrylic denture base remains problematic. Acrylic prosthesis fractures are commonly observed in prosthodontic practice and have not been reliably resolved. This study compared the resistance to masticatory force of acrylic bases of removable complete conventional prosthesis in 3D upper models. Forty acrylic base test specimens containing two types of reinforcement meshes (20 with glass fiber meshes (FIBER-FORCE^®- Synca, Bio Composants Médicaux^TM, Tullins, France), 20 with metal meshes (DENTAURUM^®-Ispringen, Germany)), 20 with a conventional PMMA acrylic base (LUCITONE 199^®-Dentsply Sirona, York, PA, USA), and 20 using a permanent soft reline material (MOLLOPLAST-B^®-DETAX GmbH & Co. KG, Ettlingen, Germany) were tested—a total of 80 specimens. Half of the specimens were made for a low alveolar ridge and half for a high alveolar ridge. The data were analysed using one-way analysis of variance and Student’s t-test for independent test specimens. In the high-alveolar-ridge group, the prosthesis reinforced with the glass fiber mesh was the most resistant to fracture, while in the low-alveolar-ridge group, the non-reinforced prosthesis showed the highest resistance masticatory force. Prostheses with the permanent soft reline material showed the lowest resistance to fracture in both high and low-alveolar-ridge groups. The results show that the selection of the right reinforcement material for each clinical case, based on the height of the alveolar ridge, may help to prevent prosthesis fractures.
