In the last 10 years, tremendous improvements in strength and shade selection for resin composites have been achieved. Also, a new generation of enamel-dentin bonding systems has been developed, and patient expectations of esthetic treatment have risen. Several techniques are available for restoring posterior teeth. When a caries lesion is limited, a direct esthetic restoration is indicated. Essential elements for obtaining good, long-term clinical results for direct esthetic restorations of posterior teeth are: (1) cavity preparation; (2) knowledge of the characteristics of the three dental substrates; (3) rubber dam use and matrix and wedge placement; (4) correct use of the enamel-dentin bonding system; (5) proper selection of the resin composite material; (6) use of the multilayering technique; (7) finishing and polishing procedures; and (8) maintenance of the restoration.
在过去10年里,树脂复合材料的强度和色泽选择取得了巨大进步。此外,新一代牙釉质-牙本质粘结系统已经研发出来,患者对美学治疗的期望也有所提高。有多种技术可用于后牙修复。当龋损局限时,可采用直接美学修复。在后牙直接美学修复中获得良好长期临床效果的基本要素包括:(1)窝洞预备;(2)了解三种牙体组织的特性;(3)使用橡皮障以及放置成形片和楔子;(4)正确使用牙釉质-牙本质粘结系统;(5)正确选择树脂复合材料;(6)采用分层技术;(7)修整和抛光程序;以及(8)修复体的维护。
