Abstract：
BACKGROUND: To assess the long-term functional orthodontic outcome of the Tübingen palatal plate (TPP) in children with Robin sequence (RS) in comparison to age- and sex-matched healthy controls.
METHODS: Between 09/2019 and 10/2020, we performed orthodontic assessments in 41 children at our Department of Orthodontics. Included were patients with RS (17 non-syndromic; four syndromic) and healthy controls (n = 22, average age in both groups 9.9 y). Facial analyses of 2D images, digital study casts and cephalometric measurements were made.
RESULTS: The orthodontic examinations showed no statistically significant group differences regarding functional extraoral, intraoral and pharyngeal parameters, or in skeletal patterns. The relationship between the upper and lower incisors was significantly increased (overjet 4 (2-10) vs. 3 (0-9) mm; p = 0.01) with a significant deficit in the lower face proportions (Jaw Index 4.15 (1.9-9.6) vs. 2.98 (0-9); p = 0.02; Facial convexity angle 157 (149-173) vs. 159 (149-170); p = 0.01).
CONCLUSIONS: Children with RS treated with the TPP showed normal long-term functional orthodontic outcomes, thanks to the functional adaption of the stomatognathic system. However, soft tissue growth did not completely match skeletal growth, resulting in a more convex facial profile.

摘要：
背景：评估Tübingen腭板（TPP）在Robin序列（RS）儿童中与年龄和性别匹配的健康对照组相比的长期功能性正畸结果。
方法：在2019年9月至2020年10月之间，我们在正畸学系对41名儿童进行了正畸评估。包括RS患者（17例非综合征；四种综合征）和健康对照（n=22，两组平均年龄9.9岁）。二维图像的面部分析，进行了数字研究模型和头颅测量。
结果：正畸检查显示，在功能性口外，口内和咽部参数，或骨骼模式。上下切牙之间的关系显着增加（overjet4（2-10）与3（0-9）mm；p=0.01），下面部比例显着不足（颌骨指数4.15（1.9-9.6）与2.98（0-9）；p=0.02；面部凸角157（149-173）vs.159（149-170）；p=0.01）。
结论：使用TPP治疗的RS患儿显示出正常的长期功能性正畸结局，由于口颌系统的功能适应。然而,软组织生长与骨骼生长不完全匹配,导致更凸的面部轮廓。
