Microstomia is defined as an acquired or congenital condition involving a reduction of the oral aperture severe enough to compromise esthetics, nutrition, and quality of life. This clinical report describes a technique for fabricating a mandibular swing-lock complete denture with a hinge for a patient with muscular dystrophy. A hinge in the midline allowed the denture to collapse. The collapsed denture could then be inserted into the mouth and locked into position. A sectional impression technique was used and the custom hinge was designed on the cobalt-chromium metal framework of the complete denture. The protocol presented can provide a viable treatment option for edentulous patients with microstomia.
小口畸形被定义为一种后天获得性或先天性疾病，其涉及口腔开口缩小，严重程度足以损害美观、营养和生活质量。本临床报告描述了一种为患有肌肉萎缩症的患者制作带有铰链的下颌摆动锁定全口义齿的技术。中线处的铰链使义齿能够折叠。然后可以将折叠后的义齿插入口腔并锁定到位。采用了分段印模技术，定制铰链设计在全口义齿的钴铬金属框架上。所介绍的方案可为患有小口畸形的无牙患者提供一种可行的治疗选择。
