Abstract

ABSTRACT Purpose: Retainers are crucial appliances for the long-term stabilityof occlusion after orthodontic treatment. However, patient discomfort or poor aesthetics often lead to a decline in compliance. Aiming to improve upon these qualities, this article illustrates anovel method for manufacturing a modified Hawley type retainer. Materials and methods: The proposed technique utilized a 3D printer. The acrylic plate was replaced by Co-Cr, and a clear and aesthetically pleasing organic polymer was used for the labial wire. Results: The modified Hawley retainer manufactured using the 3D metal printer could be fabricated with minimum thickness by using Co-Cr. In addition, the organic polymer wire enhanced theaesthetics. Conclusion: Our modified Hawley retainer has many advantages as a useful appliance that overcomes the drawbacks of conventional retainers. Although additional testing is required, patient comfortand ease of speaking after setting in the oral cavity are expected to be superior to those achieved with conventional retainers. The metal material has excellent durability and cleanliness, which brings great benefits to patients and orthodontists. Manufacturing with a 3D printer is expected to be an excellent alternative to conventional methods.

3D打印制造的金属保持架

目的:固位器是正畸治疗后牙合长期稳定的重要工具。然而，患者不适或美观不良往往导致依从性下降。为了提高这些品质，本文举例说明了一种制造改良霍利式固位器的新方法。材料和方法:提出的技术利用3D打印机。丙烯酸板被钴铬取代，一种清晰美观的有机聚合物被用于唇线。结果:利用3D金属打印机制备的改良霍利固位体可以用Co-Cr材料制备出最小厚度的霍利固位体。此外，有机聚合物丝增强了美观性。结论:我们改良的霍利固位器克服了传统固位器的缺点，是一种实用的固位器。虽然需要进行额外的测试，但患者在口腔内固定后的舒适度和说话的便利性有望优于传统固位器。金属材料具有优异的耐用性和清洁度，为患者和正畸医生带来极大的好处。使用3D打印机进行制造有望成为传统方法的一种极好的替代方法。
