舌向集中咀嚼效能的评价

目的:比较舌向集中全口义齿与半解剖式全口义齿的咀嚼效能。方法:搜集2009—2010年就诊的刃状及低平或凹形牙槽嵴患者60例,随机分为2组,分别用舌向集中型与半解剖式型人工牙制作全口义齿,采用固定咀嚼时间与咀嚼次数,分别检测舌向集中与半解剖式全口义齿患者戴义齿1、2、3、6个月的咀嚼效率,比较两者的咀嚼效率。采用SAS6.12软件包对数据进行统计学分析。结果:咀嚼时间固定或咀嚼次数固定时,舌向集中与半解剖式全口义齿咀嚼效率无显著差异(P>0.05)。结论:针对刃状、低平及凹陷状牙槽嵴条件的无牙患者,应用舌向集中全口义齿也能恢复良好的咀嚼效能。

Evaluation of masticatory efficiency of lingualized occlusal complete denture

PURPOSE: To compare the masticatory efficiency of lingualized occlusal complete denture with that of semi-anatomical occlusal complete denture.METHODS: Sixty cases with flat or depressed residual ridges were selected from 2009 to 2011.After randomly divided into two groups,the patients were treated with lingualized and semi-anatomical occlusal complete dentures,respectively.A comparative study of masticatory efficiency was carried out on patients wearing lingualized occlusal complete dentures with those wearing semi-anatomical occlusal complete dentures in different period(1st,2nd,3rd,6th month)after wearing.SAS6.16 software package was used for data analysis.RESULTS:Once masticatory time or masticatory times were fixed,there was no significant difference between lingualized occlusal dentures and semi-anatomical occlusal complete dentures(P>0.05).CONCLUSION: Lingualized occlusal complete denture can achieve good masticatory efficiency for edentulous patients with flat or depressed residual ridges.
