摘要:

本文报道了1例应用数字化双导板技术辅助复合树脂直接粘接修复下前牙区牙间隙的临床复杂案例。针对因牙冠体积比例异常导致的下前牙宽间隙,基于数字化技术对牙体形态进行恢复,联合三维打印制作舌侧形态导板及唇侧轮廓导板。通过双导板系统精准控制复合树脂堆塑及牙体形态构建,实现了下前牙区牙间隙的微创美学修复。本病例为牙间隙微创美学修复的临床操作提供了标准化流程参考,尤其对宽间隙病例的形态功能重建具有指导意义。

Abstract:

This study presents a complex clinical case of minimally invasive esthetic restoration for mandibular anterior diastema using digital double-guide technology-assisted composite resin direct bonding. The patient exhibited abnormally proportioned dental crowns leading to wide diastema. Digital technology was employed to reconstruct optimal tooth morphology,complemented by 3D-printed lingual morphological guides and labial contour guides. The double-guide system enabled precise control of composite resin layering and morphological construction,achieving minimally invasive esthetic rehabilitation. This case establishes a standardized protocol for diastema restoration,demonstrating particular clinical significance for morphological and functional reconstruction in wide interdental spacing cases.

Key words: digitalization, double-guide technique, diastema, minimally invasive esthetics, resin restoration
