Amelogenesis imperfecta represents a group of dental developmental conditions that are genomic in origin. Hypoplastic AI, hypomineralised AI or both in combination were the most common types seen clinically. This paper describes oral rehabilitation of a 9-year-old Malay girl with inherited hypoplastic AI using transparent thermoforming templates. The defective surface areas were reconstructed to their original dimensions on stone cast models of the upper and lower arches using composite, and transparent thermoform templates were fabricated on the models. The templates were used as crown formers to reconstruct the defective teeth clinically using esthetically matching composite. The usage of the templates allowed direct light curing of the composite, accurate reproducibility of the anatomic contours of the defective teeth, reduced chair-side time and easy contouring and placement of homogenous thickness of composite in otherwise inaccessible sites of the affected teeth.
牙釉质发育不全是一组起源于基因组的牙齿发育病症。临床所见最常见的类型是发育不全型AI、矿化不足型AI或两者兼有的组合型。本文描述了一名9岁患有遗传性发育不全型AI的马来女孩使用透明热成型模板进行口腔修复的情况。在上下牙弓的石膏模型上，使用复合材料将缺损的表面区域重建至原始尺寸，并在模型上制作透明热成型模板。这些模板用作牙冠成型器，临床上使用美观匹配的复合材料重建缺损牙齿。模板的使用使得复合材料能够直接光固化，缺损牙齿的解剖轮廓得以精确重现，减少了椅旁操作时间，并且在患牙原本难以操作的部位能够轻松塑形并放置均匀厚度的复合材料。
