(1) Background: Due to the limitations of composite cements, the authors carried out tests to compare such materials with preheated composite materials because the latter may be an alternative to cements in the adhesive cementation procedure. (2) Methods: The materials used in the adhesive cementation procedure, i.e., Enamel Plus Hri (Micerium, Avegno, Italy), a heated composite material, and RelyX U200 Automix (3M, Maplewood, MN, USA), a dual composite cement, were tested for microhardness, compressive strength, flexural strength, diametral compressive strength, and elastic modulus. Composite material was heated to the temperature of 50 degrees Celsius before polymerisation. (3) Results: Higher values of microhardness (by 67.36%), compressive strength (by 41.84%), elastic modulus (by 17.75%), flexural strength (by 36.03%), and diametral compressive strength (by 45.52%) were obtained using the Enamel Plus Hri composite material compared to the RelyX U200 self-adhesive cement. The survey results revealed statistically significant differences. (4) Conclusions: Due to its better mechanical properties, the heated composite material (Enamel Plus Hri) is a beneficial alternative to composite cements in the indirect restoration placement procedure. As the strength parameters of the heated composite material increase, a higher resistance to the compressive and bending forces present in the oral cavity, and hence a greater durability of the created prosthetic reconstructions can be expected.
(1) 背景：由于复合粘结剂存在局限性，作者开展了测试，以将此类材料与预热复合材料进行比较，因为后者可能是粘结粘结过程中粘结剂的替代材料。(2) 方法：对粘结粘结过程中使用的材料，即Enamel Plus Hri（意大利阿韦尼奥的米切里姆公司），一种加热的复合材料，以及RelyX U200自动混合装（美国明尼苏达州枫木市的3M公司），一种双组分复合粘结剂，进行了显微硬度、抗压强度、抗弯强度、径向抗压强度和弹性模量测试。复合材料在聚合前加热至50摄氏度。(3) 结果：与RelyX U200自粘结粘结剂相比，使用Enamel Plus Hri复合材料获得了更高的显微硬度值（提高了67.36%）、抗压强度值（提高了41.84%）、弹性模量值（提高了17.75%）、抗弯强度值（提高了36.03%）和径向抗压强度值（提高了45.52%）。调查结果显示存在统计学上的显著差异。(4) 结论：由于其更好的力学性能，加热的复合材料（Enamel Plus Hri）在间接修复体放置过程中是复合粘结剂的有益替代材料。随着加热复合材料强度参数的增加，可以预期对口腔中存在的压缩力和弯曲力具有更高的抵抗力，从而使所创建的修复重建具有更高的耐久性。
