不同全口义齿重衬材料的稳固性、舒适度和咀嚼功能比较研究

目的探讨不同全口义齿重衬材料修复牙列缺失的临床效果。方法选择我院收治的90例无牙颌患者为研究对象,根据修复材料不同分为自凝组、热凝组及软衬组。比较三组修复的稳固性、舒适度及咀嚼功能恢复情况。结果重衬修复后6个月评价固位改善情况,软衬组重衬后固位Ⅲ级比例（60%）显著高于自凝组（33.3%）和热凝组（40%）,软衬组重衬后悬浊液OD值（4.216±0.332）显著高于自凝组（3.109±0.312）和热凝组（3.125±0.325）,软衬组固位效果（9.4±0.8）、咀嚼功能（9.3±0.7）、舒适度评分[（9.3±0.6）分]均显著优于自凝组[（6.1±0.9）分、（5.8±0.8）分、（6.0±0.9）分]、热凝组[（6.5±0.8）分、（6.3±0.8）分、（6.4±0.8）分],差异均有统计学意义（P〈0.05）。结论 Sofreliner MS软衬材料固位效果良好,患者义齿舒适性高,咀嚼功能改善显著,适用于牙槽嵴吸收不均、弹性差的义齿重衬。

Comparison on the stability,comfort and chewing function of different denture materials in complete teeth repair

Objective To study the clinical effect of different denture material in complete teeth repair.Methods Ninety cases of edentulate patients with edentulous jaw were chosen as research objects, which were divided into self-curing group, heat setting group and soft lining group according to different restorative materials. Repair stability, comfort and chewing function recovery were observed. Results Six months after relining repair, the retainer Ⅲ level in soft lining group was significantly higher than that in self-curing group and heat setting group（60% vs33.3% and 40%）. Suspension OD value in soft lining group（4.216 ± 0.332） was significantly higher than that in self-curing group（3.109±0.312） and the heat setting group（3.125±0.325）. The retention effect, chewing function and comfort score in soft lining group [（9.4±0.8）,（9.3±0.7） and（9.3±0.6）, respectively] were significantly better than that in self-curing group [（6.1±0.9）,（5.8±0.8） and（6.0±0.9）, respectively] and heat setting group [（6.5±0.8）,（6.3±0.8） and（6.4±0.8）, respectively]. Conclusion The effect of Sofreliner MS soft lining materials is good, which provides high comfort denture and improves chewing function significantly. It is applicable to absorb uneven alveolar ridge with poor elastic denture liner.
