个别托盘在重度牙槽嵴吸收的覆盖义齿取模中的应用

Application of individualized pallet to overdenture moulding in patients with severe alveolar ridge resorption

目的:探讨个别托盘在重度牙槽嵴吸收的覆盖义齿修复取模中的应用。方法:选择2016年7月～2017年12月在我科就诊的牙槽嵴重度吸收行覆盖义齿修复的患者6例,男2例,女4例,红膏+藻酸盐取初印模,常规灌注石膏模型,制作自凝塑料个别托盘,取终印模,灌注石膏模型,常规测合,试排牙,试戴,调磨,1周、3周、3个月后复诊,填写问卷调查报告。结果:义齿完成后初戴,调合后咬合稳定,无左右翘动,咬合接触广泛均匀,边缘密合; 1周、3周后复诊,局部压痛少,舒适度、咀嚼效能高; 3个月后复诊,义齿无压痛,无翘动,边缘密合,固位好,满意度高。结论:个别托盘提高了印模的精确性,提高了义齿的适合性和患者满意度。

Objective: To assess the outcomes of applying individualized pallet to overdenture moulding patients with severe alveolar ridge resorption. Methods :Six patients(2 males,4 females) with severe alveolar ridge resorption undergone overdenture restoration in our department were enrolled from July 2016 to December 2017.Initial moulding was performed using red impression compound with dental alginate,followed by conventional gypsum perfusion to prepare individualized pallet using self-curing resin.Final impression was injected with dental plaster,and subjected to testing of the horizontal and vertical level,teeth aligning and repeated adjustment via grinding of the dentures in interval of 1 week,3 weeks and 3 months during which questionnaire was used to maintain the patients′ experience. Results :Initial implantation of the overdenture indicated stable and uniform occlusion without horizontal tilting.Follow-up visit in 1 week and 3 weeks showed less local pressure pain,yet higher comfort and chewing capacity.By three month after denture implantation,the pressure pain totally vanished.The overdutures was completely fixed and fitted,with which the patients had higher satisfaction. Conclusion :Individualized pallet can improve accurate moulding,denture occlusion and patients′ satisfaction.
