It is the responsibility of the dentist to fabricate a denture that is fully functional and perfectly esthetic. One prime oral function that has always been overlooked in this regard is speech. It has been thought that speech will follow mere replacement of teeth and that it is the patient's duty to fine tune this function with practice. Phonetics, esthetics, function and comfort form the foundation of a successful prosthodontic treatment. Accurate approximation of palatal contours of a maxillary complete denture to a patient's tongue can improve speech intelligibility, if other factors such as tooth position, occlusal plane and occlusal vertical dimension are satisfactory. Customizing palatal contours of a maxillary complete denture can be accomplished by using tissue-conditioning material, which provides sufficient working time for a patient to pronounce a series of sibilant sounds while recording dynamic impression of the tongue. This article describes a technique of obtaining palatogram and customizing palatal contours of a maxillary complete denture with autopolymerizing acrylic resin to improve the intelligibility of speech.
制作一副功能完备且美观无瑕的假牙是牙医的职责。在这方面一直被忽视的一项主要口腔功能是言语功能。人们一直认为,只要换上牙齿,言语功能自然就会恢复,患者有责任通过练习来微调这项功能。语音、美观、功能和舒适度构成了成功的口腔修复治疗的基础。如果牙齿位置、咬合平面和咬合垂直距离等其他因素令人满意,那么上颌全口义齿的腭部轮廓与患者舌头的精确贴合可以提高言语清晰度。通过使用组织调整材料来定制上颌全口义齿的腭部轮廓,该材料可为患者提供足够的操作时间,以便在记录舌头的动态印模时发出一系列咝音。本文介绍了一种获取腭图并用自凝丙烯酸树脂定制上颌全口义齿腭部轮廓以提高言语清晰度的技术。
