目的:探讨选择性压力印模在下颌后牙游离缺失中的应用效果。方法:通过对临床上38例下颌远中游离缺失的Kennedy一二类患者采用选择性压力印模制作支架式可摘局部义齿,追踪其治疗效果。结果:32例患者义齿修复为优占84.2%,5例为中占13.2%,远超历史资料水平,效果良好。结论:选择性压力印模在下颌后牙游离缺失中的应用效果满意,提高了修复体质量。 Objective: To explore the effect of selective pressure impressions on the free deletion of mandibular posterior teeth. Methods: Seventy - eight Kennedy patients with mandibular distal mandibular distraction were treated with selective pressure implants to make scaffold removable partial dentures to track the therapeutic effect. Results: In 32 cases, the denture repair accounted for 84.2% of excellent and 5 cases of 13.2%, far exceeding the historical data and the effect was good. Conclusion: The application of selective pressure impression in the removal of mandibular posterior teeth is satisfactory and the quality of prosthesis is improved.
