Persons with oral myofunctional disorders suffer from multiple risk factors for impairments. A craniofacial malformation may be responsible for both behavioral as well as structural modifications. This includes the effect of appearance on self concept and behavior (Case, 1988). Structural modifications as well as negative oral habits include: an open mouth resting posture; mouth breathing; low forward tongue carriage; forward articulatory tongue placement (linguadental/lingua alveolar); abnormal lip, tongue and facial muscle movements during swallowing; reduced upper lip length and mobility; overcontraction of the mentalis muscle; negative habits such as nailbiting, thumb or finger-sucking, lip biting, and lip licking (Hale and Kellum, 1988). Clinical observations also include hypotonicity of the posterior oral musculature during swallowing activity. The purpose of this article is to explore the etiology of oral myofunctional disorders and present a new approach to treatment using functional prosthetic therapy.
患有口腔肌功能障碍的人面临多种导致功能受损的风险因素。颅面畸形可能是行为和结构改变的原因。这包括外貌对自我概念和行为的影响(凯斯,1988年)。结构改变以及不良口腔习惯包括:张口休息姿势;口呼吸;舌低位前伸;发音时舌前伸(舌齿/舌牙槽);吞咽时唇部、舌头和面部肌肉异常运动;上唇长度和活动度降低;颏肌过度收缩;咬指甲、吮拇指或手指、咬唇和舔唇等不良习惯(黑尔和凯卢姆,1988年)。临床观察还包括吞咽活动时口腔后部肌肉组织张力减退。本文旨在探讨口腔肌功能障碍的病因,并提出一种使用功能性修复治疗的新方法。
