目的:通过美学方法解决单侧交叉咬伤的复杂II类病例,即一种混合正畸治疗,将矫正器与微型系统和辅助系统相结合。
方法:一名14岁的女性患者,患有II类牙齿和后交叉咬伤,接受正畸治疗。患者拒绝常规的固定多支架治疗,因此接受了与微型支架和分段舌部矫治器联合使用的矫正器。提供治疗前后记录和2年随访记录。
结果:治疗目标,即理想的遮挡和改进的轮廓,在12个月内实现。治疗后全景摄影显示良好的根平行度,没有牙髓骨高度降低或根尖吸收的迹象。患者对功能和美学结果感到满意,稳定在2年。
结论:本病例报告表明,混合矫正器方法可用于治疗后牙合和II类错牙合,缩短治疗时间,最佳的口腔卫生和卓越的美学。
To resolve a complex Class II
case with unilateral crossbite through an aesthetic approach, namely a hybrid orthodontic treatment combining aligners with miniscrews and auxiliaries.
A 14-year-old hypodivergent female patient with dental Class II and posterior crossbite presented for orthodontic treatment. The patient refused conventional fixed multibracket treatment and was therefore prescribed aligners used in association with miniscrews and sectional lingual appliances. Pre- and post-treatment records and 2-year follow-up records are presented.
Treatment objectives, namely ideal occlusion and improved profile, were achieved in 12 months. Post-treatment panoramic radiography showed good root parallelism, and no sign of either crestal bone height reduction or apical root resorption. The patient was satisfied with the functional and aesthetic outcomes, which were stable at 2 years.
This
case report illustrates that a hybrid aligner approach may be used to treat posterior crossbite and class II malocclusion with reduced treatment times, optimal oral hygiene and excellent aesthetics.
