Abstract：
Early loss of deciduous teeth is a challenging situation to handle. In recent years, the loss of deciduous teeth has become very frequent because of the increased risk of caries. Space maintainers play a vital role in preventing space loss. Lingual arch space maintainers are effectively used to maintain space in the lower arch. In order to retain the length of the lower arch and to prevent mesial migration of the mandibular first permanent molar, lingual arch space maintainers are often indicated. Conventional lingual arch fabrication is technique-sensitive and cumbersome. Additionally, it has many documented drawbacks like solder breakage, cement loss, soft tissue lesions, etc. With the advent of newer technology like three-dimensional (3D) printing, the fabrication of appliances and prostheses has become more predictable, accurate, and relatively easier. The present case report highlights the technique and advantages of 3D printing to fabricate lingual arch space maintainers, which has the potential to revolutionize preventive orthodontics in pediatric dentistry.
摘要：
乳牙的早期脱落是一种具有挑战性的情况。近年来,由于龋齿的风险增加，乳牙的脱落变得非常频繁。空间维护者在防止空间损失方面起着至关重要的作用。有效地利用了舌弓空间保持者来保持下弓的空间。为了保留下弓的长度并防止下颌第一恒磨牙的内侧迁移，舌弓空间维护者经常被指示。传统的舌弓制造技术敏感且麻烦。此外,它有许多记录的缺点，如焊料破裂，水泥损失，软组织病变,等。随着三维（3D）打印等新技术的出现，矫正器和假肢的制造变得更加可预测，准确,相对容易。本案例报告强调了3D打印制造舌弓空间维护者的技术和优势，这有可能彻底改变儿科牙科的预防性正畸。
