Anterior open bite is a challenging condition for pediatric dentists and orthodontists as it causes aesthetic, speech, feeding, and psychological problems; this emphasizes the need for early diagnosis and interception of this malocclusion.
This study aimed to evaluate the effects of prefabricated metal-bonded tongue tamers and customized bonded spurs in the early treatment of anterior open bite.
A sample of seventy-five children aged 7-9 years were assigned into three groups in which anterior open bite was treated using tongue tamers (group-I), customized composite bonded spurs(group-II), and conventional fixed palatal cribs (group-III). Study model and cephalometric x-ray evaluations were done before and after a three-month follow-up. Data was gathered and statistically analyzed using ANOVA and Bonferroni tests.
Model overbite at central and lateral incisors was increased in all groups. The highest increase was found in group-I(3.16 ± 1.17, 2.81 ± 0.94)and group-III(3.08 ± 1.10,2.99 ± 1.00) though the difference was not statistically significant. Also, cephalometric overbite was non-significantly increased in all groups with a high increase in group-III(3.13 ± 1.10). Overjet decreased in all groups, with the greatest reduction observed in group-I(-2.58 ± 1.02 and -2.47 ± 0.80 in model and cephalometric respectively) and was significantly different from group-II using pairwise analysis. There was a decrease in SNA and ANB in all groups with more significant improvement in groups-I(-1.20 ± 0.88,-1.65 ± 0.74) and -III(-1.31 ± 0.92, -1.62 ± 0.75) than group-II(-0.63 ± 0.46, -0.90 ± 0.43). Moreover, FMA measurements decreased significantly in group-I (-2.6 ± 1.11). Regarding SNB measurement, there was a non-significant increase in all three groups with the highest increase in group-I(0.49 ± 0.48) followed by group-III(0.34 ± 0.63). The U1/FHP and L1/GoGn angles were non-significantly decreased in all tested groups with the highest decrease in group-I(-1.76 ± 1.00 and-2.54 ± 0.87 respectively).
Early treatment of anterior open bite, along with tongue tamers' simplicity and aesthetics promoted the malocclusion correction and occlusal function restoration.

前牙开颌对儿童牙医和正畸医生来说是一个具有挑战性的病症，因为它会导致美观、言语、进食和心理问题；这凸显了对这种错颌畸形进行早期诊断和干预的必要性。
本研究旨在评估预制金属粘结舌刺和定制粘结牙刺在前牙开颌早期治疗中的效果。
选取75名7至9岁的儿童作为样本，分为三组，分别使用舌刺（第一组）、定制复合粘结牙刺（第二组）和传统固定腭托（第三组）治疗前牙开颌。在三个月的随访前后进行研究模型和头影测量X线评估。收集数据并使用方差分析和邦费罗尼检验进行统计分析。
所有组中，中切牙和侧切牙的模型覆合均增加。第一组（3.16±1.17，2.81±0.94）和第三组（3.08±1.10，2.99±1.00）的增加幅度最大，尽管差异无统计学意义。此外，所有组的头影测量覆合均有非显著性增加，第三组增加幅度较大（3.13±1.10）。所有组的覆盖均减小，第一组减小幅度最大（模型和头影测量分别为-2.58±1.02和-2.47±0.80），经两两分析，与第二组有显著差异。所有组的SNA和ANB均减小，第一组（-1.20±0.88，-1.65±0.74）和第三组（-1.31±0.92，-1.62±0.75）的改善比第二组（-0.63±0.46，-0.90±0.43）更显著。此外，第一组的FMA测量值显著降低（-2.6±1.11）。关于SNB测量，三组均有非显著性增加，第一组增加幅度最大（0.49±0.48），其次是第三组（0.34±0.63）。所有测试组的U1/FHP和L1/GoGn角均有非显著性降低，第一组降低幅度最大（分别为-1.76±1.00和-2.54±0.87）。
前牙开颌的早期治疗，以及舌刺的简便性和美观性，促进了错颌畸形的矫正和咬合功能的恢复。
