将商业牙科复合材料中使用的一小部分液体树脂添加到商业玻璃离聚物修复剂中使用的液体中，以产生含氟化物的混合修复型材料，该材料将粘附到牙本质上，同时比玻璃离聚物更坚固，更不脆，并且对口腔中的干燥更不敏感。压缩强度，屈服强度，弹性模量，断裂韧性，和拉伸强度进行了分析，这种混合，轻弯曲材料。此外，还对材料的水溶性、与牙本质的粘附性和表面粗糙度进行了体外实验。结果表明，杂化材料的早期（一小时）的力学性能超过玻璃离子。此外，该材料的脆性和溶解性小于商业玻璃离子，而对牙本质的粘附性不受影响。最重要的是，表面裂纹，一个记录的问题，一些玻璃离聚物时，他们变得干燥，是减轻与这种混合配方。
A small percentage of the liquid resin used in commercial dental composites was added to the liquid used in a commercial glass-ionomer restorative in order to produce a fluoride-containing hybrid restorative-type material that would adhere to dentin while being stronger, less brittle, and less sensitive to desiccation in the oral cavity than glass ionomer. Compressive strength, yield strength, elastic modulus, fracture toughness, and tensile strength were analyzed for this hybrid, light-curved material. In addition, the solubility in water, adhesion to dentin, and surface roughness were also examinedin vitro. The results suggest that the early (one-hour) mechanical properties of the hybrid material exceed those of glass ionomer. In addition, the brittleness and solubility of the material are less than those of commercial glass ionomer, while adhesion to dentin is unaffected. Most importantly, surface crazing, a documented problem with some glass ionomers when they become desiccated, is alleviated with this hybrid formulation.
