Abstract

A microporous filler giving greatly improved finish ability, systemic nontoxic X-ray opacification, low thermal expansion (27.2 x 10(-6)/degrees C), and satisfactory translucencies has been developed for dental composite resin restorations. These fillers are prepared from frits obtained by the low-temperature calcination of gelled inorganic sols followed by a pulsed high-temperature treatment. Composites prepared from these fillers are within the range of commercial products with regard to strength and setting contraction.

摘要

已开发出一种用于牙科复合树脂修复体的微孔填料，其具有显著改善的光洁度、全身性无毒X射线不透明度、低热膨胀率（27.2×10⁻⁶/℃）和令人满意的透明度。这些填料由通过凝胶态无机溶胶的低温煅烧然后进行脉冲高温处理获得的玻璃料制备而成。由这些填料制备的复合材料在强度和固化收缩方面处于商业产品的范围内。
