摘　　要：目的:将按扣式分段全口义齿应用于无牙颌小口畸形患者的修复中,评价其修复效果。方法:采用分段式印模技术。沿中线两侧的全口义齿上制作腭部按扣式机械结构。在两侧金属支架相当于上中切牙的位置,各做半个金属基牙,并在此之上制作烤塑冠。义齿就位时,同时将烤塑冠就位,将整个义齿连成一体,并提供稳定作用。结果:按扣式分段全口义齿能够在患者口腔中自如就位,并发挥良好的功能。结论:按扣式分段上颌全口义齿可用于无牙颌小口畸形患者的修复。PURPOSE： Prosthetic rehabilitation with stud structure to sectional complete denture for a patient with microstomia was done and the treatment result was evaluated. METHODS： A sectional impression tray technique was used. And a custom-made palatal hinge mechanism with stud structure on the left and fight side of the upper complete denture along the middle line were also designed and fabricated, Half metal abutment was fabricated on the left and fight side of the denture on the position of the upper central incisor, and a PFM was made according to the metal abutment, After the sectional upper complete denture was inserted, the PFM was set to connect the sectional denture as a whole and provide stability. RESULTS： The sectional upper complete denture was successfully and easily inserted and provided adequate function in the patient＇s mouth, CONCLUSIONS： Application of stud structure to sectional upper complete denture for patient with microstomia is feasible.
