数字化辅助诊断及正畸治疗下颌侧切牙埋伏阻生 1 例报告

BACKGROUND: The impaction of mandibular lateral incisors presents significant aesthetic and functional challenges in orthodontics, including Bolton ratio discrepancies and anterior occlusal anomalies. The increasing preference for nonextraction treatment further complicates space management within the dental arch. However, the advent of digital-assisted orthodontic technologies, particularly advanced digital simulations, has revolutionized the precision and effectiveness of diagnosis and treatment planning. These technologies enable clinicians to strategically leverage natural jaw development and create the necessary space for the alignment of impacted teeth without resorting to extraction. CASE PRESENTATION: This case report details the treatment of a 12-year-old male with an impacted mandibular lateral incisor, which resulted in both aesthetic concerns and functional impairments, alongside Class II malocclusion. By employing a digital-assisted diagnostic approach, including comprehensive digital simulations, we meticulously evaluated the feasibility of a nonextraction treatment plan. The strategy centred on harnessing the patient's mandibular growth potential to expand the available space naturally. The treatment involved surgical exposure of the impacted tooth, followed by precise orthodontic traction guided by continuous digital monitoring. The integration of digital tools throughout the treatment process was crucial in achieving successful eruption and alignment of the impacted tooth, thus restoring optimal aesthetics and function without the need for extraction. CONCLUSION: This case highlights the transformative impact of digital-assisted technologies in the management of complex orthodontic cases, such as impacted mandibular lateral incisors. The successful integration of these advanced tools with a nonextraction treatment approach underscores their potential to significantly enhance clinical outcomes. Digital technologies not only improve the accuracy and effectiveness of treatment but also facilitate a multidisciplinary approach that elevates the standard of patient care in addressing complex orthodontic challenges.

背景：下颌侧切牙阻生在正畸学中带来了显著的美学和功能挑战，包括 Bolton 比率不调以及前牙咬合异常。越来越多的人倾向于非拔牙治疗，这进一步增加了在牙弓内管理空间的复杂性。然而，数字化辅助正畸技术的出现，特别是先进的数字化模拟，彻底改变了诊断和治疗计划的精确性和有效性。这些技术使临床医生能够战略性地利用自然颌骨发育，并为阻生牙的对齐创造必要的空间，而无需拔牙。

病例介绍：本病例报告详细介绍了一名 12 岁男性下颌侧切牙阻生的治疗情况，该患者不仅存在美学问题，还存在功能障碍以及 II 类错颌。通过采用数字化辅助诊断方法，包括全面的数字化模拟，我们仔细评估了非拔牙治疗计划的可行性。该策略的核心是利用患者的下颌生长潜力自然扩展可用空间。治疗包括手术暴露阻生牙，然后通过持续的数字化监测引导精确的正畸牵引。在整个治疗过程中整合数字化工具对于成功实现阻生牙的萌出和对齐至关重要，从而在无需拔牙的情况下恢复最佳的美观和功能。

结论：本病例突出了数字化辅助技术在管理复杂正畸病例（如下颌侧切牙阻生）方面的变革性影响。这些先进工具与非拔牙治疗方法的成功整合突显了它们在显著提高临床效果方面的潜力。数字化技术不仅提高了治疗的准确性和有效性，还促进了多学科方法的应用，从而提高了解决复杂正畸挑战时的患者护理标准。
