There is an association between increased overjet and risk of trauma to the maxillary incisor teeth in children and adolescents. It would therefore seem sensible to recommend overjet reduction as early as possible to help reduce this risk. However, orthodontic outcomes are essentially the same whether you start treatment in the early or late mixed dentition, while early treatment carries a heavier burden on compliance - taking longer and involving more appointments. This article explores the complex association between early overjet reduction and dental trauma in the context of current best evidence. Careful case selection is advised when justifying early intervention for increased overjet based on reducing trauma risk.
上颌切牙外伤风险与覆𬌗增加之间存在关联。因此,建议尽早减少覆𬌗,以降低这种风险,这似乎是合理的。然而,无论在早期混合牙列还是晚期混合牙列开始治疗,正畸治疗结果基本相同,而早期治疗的顺应性负担更重——治疗时间更长,需要更多的预约。本文在现有最佳证据的基础上,探讨了早期减少覆𬌗与牙齿外伤之间的复杂关系。在基于降低外伤风险的情况下,为增加的覆𬌗进行早期干预时,建议仔细选择病例。
