摘要： 目的: 评估激光熔融技术打印的钴铬合金翼板形舌侧保持器在临床上的使用效果。方法: 选取12例正畸治疗结束后的患者,6例通过激光熔融技术制作钴铬合金翼板形舌侧保持器,6例患者制作常规的舌侧丝固定保持器。所有保持器通过树脂粘接在下颌牙齿上,分别记录两种保持器的椅旁粘接操作时间,粘接后1、3、6个月,分别对两组保持器的固位及形变、牙列保持效果、牙周健康指数、舒适度等进行评估。结果: 金属翼板组椅旁操作时间为(5.27±2.58) min,显著低于舌侧丝固定组的(10.07±2.71) min(P＜0.05)。保持器佩戴半年内,金属翼板组的固位和形变、牙列保持效果、牙周健康指数、舒适度等评估指数显著优于舌侧丝固定组的(P＜0.05)。结论: 激光熔融技术打印的钴铬合金翼板形舌侧保持器各项性能能够满足临床要求。

Abstract: Objective: To evaluate the clinical performance of metal wing lingual retainer. Methods: Twelve patients after orthodontic treatment were selected. Six patients used the lingual retainer of cobalt-chromium alloy wing printed by laser fusion technology, and 6 patients used the lingual wire fixed retainer. All the retainers were bonded to the mandibular teeth by resin adhesive. The bonding operative time were recorded, and the retainer retention and deformation, dentition retention, periodontal health index, and comfort were evaluated at 1, 3, and 6 months after bonding. Results: The chair-side time of metal wing group (5.27±2.58) min was shorter than that of lingual wire group (10.07±2.71 min, P<0.05). The retention and deformation, dentition retention, periodontal health index, and Comfort Index of metal wing group were better than that of lingual wire group (P＜0.05). Conclusion: Metal wing lingual retainer printed by laser fusion technique could meet the clinical requirements.
