Esthetic treatment of a single darkened tooth represents a great challenge to the dental practitioner. The properties of dental ceramic-colour stability, mechanical strength, clinical longevity, esthetic appearance and compatibility with periodontal tissues-make this material a good choice for such treatment. We present a case of restoration of a single, highly darkened anterior tooth with a feldspathic porcelain veneer. Resolution involved preparation of the dental structure guided by orientation grooves and provisional restoration using composite resin, a silicone impression and adhesive luting. Conservative use of porcelain laminate veneers provides satisfactory esthetic outcomes and preserves sound tooth structure. The patient was very satisfied with the result and had no complaints during 2 years of follow-up.
对单颗变色牙进行美学治疗对牙科医生来说是一项巨大的挑战。牙科陶瓷的特性——颜色稳定性、机械强度、临床使用寿命、美学外观以及与牙周组织的兼容性——使其成为此类治疗的理想材料。我们报告一例使用长石质瓷贴面修复单颗高度变色前牙的病例。治疗步骤包括在定向沟引导下预备牙体结构,使用复合树脂进行临时修复、硅橡胶印模和粘结固位。保守使用瓷贴面可提供令人满意的美学效果,并保留完好的牙体结构。患者对治疗结果非常满意,在两年的随访期间无任何不适主诉。
