摘要 目的利用"中性区技术"制作全口义齿,并探讨该技术对修复体(全口义齿,特别是下颌全口义齿)稳定性的作用。方法随机选取28例无牙颌患者,采用二次印模法,"中性区技术"排牙,制作全口义齿,并使基托磨光面呈凹面形,观察临床效果。结果通过该方法制作的全口义齿固位性、稳定性明显提高,且很少发生黏膜压痛,取得了较满意的临床效果。结论准确的印模和颌位关系,人工牙的正确中性区位置,可以提高全口义齿的稳定性和舒适度。 Objective To use the neutral zone technique to make complete denture,and investigate the effect of neutral zone teeth arrangement technique on the stability of denture. Methods A total of 28 edentulous patients were randomly chosen,and the complete denture was finished with a two-step impression method,and the neutral zone position of artificial teeth was paid attention to. The polished surface morphology was concave. Results The stability of complete denture was enhanced with rarely mucosal tenderness,and the clinical results were satisfactory. Conclusions The more accurate impression and jaw position and correct neutral position of artificial teeth result in the improvement of the stability and comfort of complete denture by neutral zone teeth arrangement.
