The restoration of primary incisors with extensive caries lesions is a clinical challenge of severe dimensions. Not only are these teeth difficult to restore, but the patient's behavior can affect the treatment negatively. Requirements for an acceptable restoration include natural color; durability; adhesive cementation that is biocompatible with the pulp; easily and rapidly placed; requires only one treatment visit. Compared to other options, stainless steel crowns are the easiest to place. The most attractive restoration for these cases today is the adhesively bonded resin-composite crown, made by using acetate crown-form matrices, but this is being surpassed by the stainless steel crown forms (3M Unitek) that can be preveneered. This article describes a step-by-step method of placing preveneered stainless steel crowns for primary incisors.
对患有大面积龋损的乳前牙进行修复是一项极具挑战性的临床难题。这些牙齿不仅修复难度大，而且患者的行为还可能对治疗产生负面影响。可接受的修复体要求包括自然的颜色、耐用性、与牙髓生物相容性良好的粘结水门汀、易于快速放置且仅需一次就诊治疗。与其他选择相比，不锈钢冠最容易放置。目前，对于这些病例最具吸引力的修复体是使用醋酸酯冠形基质制作的粘结树脂复合冠，但这种修复体正被可预成型的不锈钢冠（3M Unitek）所超越。本文介绍了一种为乳前牙放置预成型不锈钢冠的分步方法。
