三种全口义齿重衬材料临床应用的比较

Clinical comparison among three kinds of denture relining materials

背景:对于无牙颌患者而言,由于牙槽嵴的吸收,全口义齿戴用一段时间后,口腔黏膜与基托不密合,出现义齿固位不良,临床上常采取基托重衬解决义齿固位问题。目的:观察SofrelinerMS软衬材料、自凝树脂和热凝树脂3种材料在不同牙槽嵴和黏膜条件患者中全口义齿重衬后的临床效果。方法:选择2009-09/2011-09期间就诊于内蒙古医学院附属医院口腔修复科中为牙槽嵴、牙龈条件优和劣组患者各30例,将牙槽嵴、牙龈条件优和劣组各随机等分为3个亚组分别采用SofrelinerMS软衬材料、自凝树脂、热凝树脂进行全口义齿重衬,衬垫1年后复查,比较3种材料重衬后的义齿固位、舒适度、咀嚼功能恢复的满意度及清洁情况。结果与结论:牙槽嵴、牙龈条件劣组患者中采用SofrelinerMS软衬材料重衬义齿的修复效果明显优于自凝树脂、热凝树脂(P<0.05);而牙槽嵴、牙龈条件优组中3种材料的修复效果差异无显著性意义(P>0.05)。提示对于牙槽嵴、牙龈条件差的患者,应用SofrelinerMS软衬材料重衬义齿可使义齿稳固、舒适、并有效提高咀嚼功能。

BACKGROUND：Due to the absorption of alveolar ridge,edentulous patients present with poor denture retention after denture wearing over time.In clinic,base relining is often adopted to address complete denture retention.OBJECTIVE：To observe the clinical effect of Sofreliner MS soft lining materials,self-curing resin and thermoplastic resin in different conditions of alveolar ridge mucosa in patients with complete denture relining.METHODS：The Sofreliner MS soft lining materials,self-curing resin,thermoplastic resin were used in edentulous patients receiving complete denture relining under different ridge and mucosal conditions.After 1 year＇s review,the three kinds of materials were compared in denture retention,comfort level,satisfaction,masticatory function and denture cleanliness.RESULTS AND CONCLUSION：For patients with poor alveolar ridge or mucosa conditions,the Sofreliner MS soft lining materials had a rebasing denture effect obviously superior to the self-curing resin and thermoplastic resin（P 0.05）;for patients presenting with good alveolar ridge and mucosal conditions,three material repair effect had no significant difference（P 0.05）.If the alveolar ridge or mucosa conditions are poor for patients,the application of Sofreliner MS soft lining materials for rebasing denture can make the denture comfort and improve the masticatory function effectively.
