Anterior open bite (AOB) is a malocclusion that generates aesthetic, speech, feeding and psychological issues, a fact that emphasises the importance of conducting early treatments to fix the disorder. Finger-sucking, pacifiers and oral habits are the main aetiological factors of AOB; thus, it is necessary to apply interceptive treatments focused on correcting and improving bite stability during childhood in order prevent the need of undergoing advanced therapy. The aim of this article is to present the early diagnosis of aetiological factors causing severe AOB and the interceptive treatment based on the use of bonded lingual spurs for one year. Results showed excellent bite stability after two years of follow-up; in other words, the proper treatment applied for the recommended growth and developmental periods enabled case stability.
前牙开颌（AOB）是一种错颌畸形，会引发美观、言语、进食及心理问题，这一事实凸显了进行早期治疗以矫正该病症的重要性。吮指、使用安抚奶嘴及口腔习惯是前牙开颌的主要病因；因此，有必要在儿童期进行旨在纠正和改善咬合稳定性的阻断性治疗，以避免需要接受进阶治疗。本文的目的是介绍导致严重前牙开颌的病因的早期诊断以及基于使用粘结舌刺一年的阻断性治疗。结果显示，经过两年随访，咬合稳定性极佳；换句话说，在推荐的生长发育期进行适当治疗可使病例保持稳定。
