牙医越来越意识到舌头和嘴唇的力量对牙齿及其支撑结构的影响。1 -4这包括舌头与咀嚼、吞咽和后天习惯模式有关的功能。Wallace，5 Rogers，6 Brodie，7 Breitner，8和其他人指出，舌头从牙弓内对牙齿的力通常由脸颊和嘴唇的肌肉组织的作用来补偿。舌头对嘴唇的补偿作用施加不正常的力，可能会导致牙齿移位或导致开咬。如果由舌头产生的力被口腔中具有牙齿的相对结构补偿，则咀嚼机制将处于生理平衡，但是，如果由任何一个结构（例如舌头）施加的力超过由口腔的其他结构施加的补偿力，则可能导致牙齿位置的改变。本研究的目的是确定舌和口周结构对上下颌牙槽突和牙列的最大作用力以及吞咽时的侧向力。这项研究是在没有明显异常的口腔中进行的，这些异常是由于舌头或口周结构的力量造成的。
There is an increasing awareness among dentists of the influence of the forces of the tongue and lips on the teeth and their supporting structures.1-4 This includes the functions of the tongue that have to do with chewing, deglutition and acquired habit patterns. Wallace,5 Rogers,6 Brodie,7 Breitner,8 and others have pointed out that the force of the tongue against the teeth from within the dental arches is normally compensated for by the action of the musculature of the cheeks and lips. The tongue’s exerting an abnormal force in relation to the compensating action of the lips may cause migration of the teeth or may contribute to an open bite. If forces generated by the tongue are com pensated for by opposing structures with in the oral cavity, the masticatory mecha nism will be in physiologic balance, but, if the forces exerted by any one structure, for example, the tongue, are in excess of the compensating forces exerted by the other structures of the oral cavity, a change of tooth position might result. The purpose of this study was to de termine the maximum forces that can be exerted by the tongue and the perioral structures on the alveolar process of both the maxilla and mandible and on their respective dentitions and the degree of lateral forcc exerted in swallowing. The study was made on mouths with no ap parent abnormalities due to the forces of the tongue or the perioral structures.
