Restorative treatment of microdontia teeth is often considered as the final step of post-orthodontic treatment. Based on digital workflow, this clinical report presents pre-orthodontic reshaping of anterior teeth in the smile disharmony of a young patient using bilayering composite injection technique. Transparent silicone indexes for dentin and enamel fillings were fabricated from three-dimensional-printed models of the digital wax-up. This noninvasive, simple and straightforward injection technique was able to provide semipermanent reversible aesthetic restorations while awaiting for adulthood and definitive prosthodontic solution. Closure of diastemas before orthodontic treatment were carried out to restore functional contact point and to guide future teeth movements.
过小牙的修复治疗通常被视为正畸后治疗的最后一步。基于数字化工作流程,本临床报告介绍了使用双层复合注射技术对一名年轻患者微笑不协调时的前牙进行正畸前重塑。从数字化蜡型的三维打印模型制作了用于牙本质和牙釉质充填的透明硅树脂导板。这种无创、简单直接的注射技术能够在等待成年和确定的修复解决方案期间提供半永久性可逆的美学修复。在正畸治疗前关闭牙间隙,以恢复功能性接触点并引导未来牙齿移动。
