Dentists are accustomed to advantages and disadvantages in the materials at their disposal. This article was concerned with one disadvantage of microfilled composite resins, namely, chip fractures. Probably due to their higher coefficient of thermal expansion, higher water sorption, higher polymerization shrinkage, and lower tensile strengths, cohesive as well as adhesive chip fractures occur three to four times more often with microfilled composite resins than with conventional composite resins. Microfilled composite resins are indicated for esthetic purposes. They are contraindicated for Class IV and stress-bearing restorations. They are indicated for limited use in Class I restorations where esthetics is of primary importance. The technique of use must include acid-etching and intermediate bonding. The microfilled composite resins enjoy a smooth finish and high luster. This offers advantages in areas where smoothness is paramount. They may replace conventional composite resins for resurfacing existing restorations and veneering stained or mottled anterior teeth. They are indicated for treatment of cervical erosion.
牙医们已经习惯了他们所使用材料的优缺点。本文关注的是微填料复合树脂的一个缺点，即片状折裂。可能由于其较高的热膨胀系数、较高的吸水性、较高的聚合收缩率以及较低的拉伸强度，微填料复合树脂发生内聚性和黏附性片状折裂的频率比传统复合树脂高三到四倍。微填料复合树脂适用于美观目的。它们不适用于IV类修复和承受应力的修复体。它们适用于美观至关重要的I类修复中的有限使用。使用技术必须包括酸蚀和中间粘结。微填料复合树脂具有光滑的表面和高光泽度。这在光滑度至关重要的区域具有优势。它们可替代传统复合树脂用于现有修复体的表面重修以及为变色或有斑点的前牙制作贴面。它们适用于治疗颈部糜烂。
