Abstract

Objective: To evaluate the effects of the rapid palatal expander (RPE) on the hyoid bone and tongue position in skeletal Class I patients, compared to control groups.

Methods: Eighty-four Class I subjects, aged 6-14, were selected. Among these, 28 patients were treated with RPE, 28 with function-generating bite (FGB) appliance, and 28 were untreated. Lateral cephalograms taken before (T0) and after (T1) treatment were retrieved. Changes in the hyoid bone and tongue position were evaluated, and the area above the tongue was measured.

Results: No significant difference in the hyoid and tongue posture was observed across the groups. However, there were significant differences for HC3 (distance from H-point to the third cervical vertebrae), H2H (distance from H-point to SN plane), and TT-Eb (tongue length) between T0 and T1 in all groups.

Conclusion: The results suggest that hyoid bone and tongue position changes were related to growth rather than treatment.

I 类受试者使用快速腭扩张器进行正畸治疗后舌骨和舌头位置的变化。

目的与对照组相比，评估快速腭部扩张器（RPE）对骨骼Ⅰ类患者舌骨和舌头位置的影响：方法：选取 84 名 6-14 岁的 I 类患者。其中，28 名患者接受了 RPE 治疗，28 名患者接受了功能性咬合矫治器（FGB）治疗，28 名患者未接受治疗。采集了治疗前（T0）和治疗后（T1）的侧头颅照片。评估舌骨和舌头位置的变化，并测量舌头上方的面积：结果：各组患者的舌骨和舌头位置无明显差异。然而，在所有组别中，HC3（H点到第三颈椎的距离）、H2H（H点到SN平面的距离）和TT-Eb（舌长）在T0和T1之间存在显著差异：结果表明，舌骨和舌头位置的变化与生长而非治疗有关。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
