Conservative dentistry: non-beveled esthetic restorations in anterior teeth

The pursuit of esthetic excellence in dentistry today requires dental practitioners to enhance their knowledge and technique in restorations of the anterior teeth. Due to the high incidence and prevalence of fractures in this dental area, mimicking the optical properties and characteristics of the dental structure in young patients (aged 6 to 15 years) is a major challenge. This case report describes the minimally invasive, non-beveled restoration of two fractured anterior teeth (class IV). After diagnosing fractures of teeth 11 and 21 in a 10-year-old patient, a composite mock-up was performed, followed by a diagnostic wax-up. With the aid of a silicon guide, the restorations were prepared without beveling the enamel surface. We performed color stratification by using different types of composite resins. Finally, finishing and polishing procedures were carried out.

当今，追求牙科美学卓越性（esthetic excellence）需牙科医师精进前牙修复的相关知识与技术。鉴于该牙区牙折发病率与流行率均较高，模拟6至15岁青少年患者牙体结构的光学特性与特征是一项重大挑战。本病例报告（case report）介绍了两例IV类洞（Class IV）折断前牙的微创无斜面修复术（minimally invasive, non-beveled restoration）。在确诊一名10岁患者的11号与21号牙发生牙折后，我们先制作了复合树脂模拟修复体（composite mock-up），随后完成了诊断性蜡型（diagnostic wax-up）。借助硅橡胶导板（silicon guide），我们在未对牙釉质表面进行斜面预备的前提下完成了修复体预备。我们采用不同类型的复合树脂开展色彩分层充填（color stratification），最终完成修形与抛光操作。
