Abstract:
Speech is a communication method found only in humans that relies on precisely articulated sounds to encode and express thoughts. Anatomical differences in the maxilla, mandible, tooth position, and vocal tract affect tongue placement and broadly influence the patterns of airflow and resonance during speech production. Alterations in these structures can create perceptual distortions in speech known as speech sound disorders (SSDs). As craniofacial development occurs, the vocal tract, jaws, and teeth change in parallel with stages of speech development, from babbling to adult phonation. Alterations from a normal Class 1 dental and skeletal relationship can impact speech. Dentofacial disharmony (DFD) patients have jaw disproportions, with a high prevalence of SSDs, where the severity of malocclusion correlates with the degree of speech distortion. DFD patients often seek orthodontic and orthognathic surgical treatment, but there is limited familiarity among dental providers on the impacts of malocclusion and its correction on speech. We sought to review the interplay between craniofacial and speech development and the impacts of orthodontic and surgical treatment on speech. Shared knowledge can facilitate collaborations between dental specialists and speech pathologists for the proper diagnosis, referral, and treatment of DFD patients with speech pathologies.
摘要:
语音是一种仅在人类中发现的交流方法,它依赖于精确表达的声音来编码和表达思想。上颌骨的解剖差异,下颌骨,齿位置,和声道会影响舌头的位置,并广泛影响语音产生过程中的气流和共振模式。这些结构的改变会在语音中产生感知失真,称为语音障碍(SSD)。随着颅面发育的发生,声道,下巴,牙齿的变化与语言发展的阶段平行,从胡言乱语到成人发声。正常的1类牙齿和骨骼关系的改变会影响言语。牙面不和谐(DFD)患者的颌骨比例失调,固态硬盘的患病率很高,其中错牙合的严重程度与语音失真程度相关。DFD患者经常寻求正畸和正颌外科治疗,但是牙科提供者对错牙合及其矫正对言语的影响的熟悉程度有限。我们试图回顾颅面和言语发育之间的相互作用以及正畸和手术治疗对言语的影响。共享的知识可以促进牙科专家和言语病理学家之间的合作,以进行正确的诊断。转介,和治疗DFD患者的言语病理学。
