舌向集中与半解剖式全口义齿的满意度及咀嚼效能比较

The comparison of denture satisfaction and masticatory efficiency between lingualized and semi-anatomic occlusal complete dentures

目的比较牙槽嵴重度吸收无牙颌患者对舌向集中牙合和半解剖式牙合2种牙合型全口义齿的满意度和咀嚼效能差异。方法选择18例牙槽嵴吸收严重的无牙颌患者,为每位患者分别制作舌向集中牙合和半解剖式牙合全口义齿各1副,随机选择其中1副义齿使用3个月后更换另1副义齿。记录每副义齿的疼痛修改次数,并于使用1、3个月后分别进行满意度问卷调查,测定咀嚼效能。结果患者对舌向集中牙合全口义齿的固位稳定和咀嚼功能评价显著优于半解剖式牙合(P<0.01)。2种牙合型义齿的咀嚼效能无显著差异(P>0.05)。舌向集中牙合全口义齿因疼痛调改的次数明显少于半解剖式。结论对于牙槽嵴吸收严重的无牙颌患者,应用舌向集中牙合型可以提高全口义齿的固位稳定和舒适程度。

Objective To compare the satisfaction and masticatory efficiency of lingualized and semi-anatomic occlusal dentures. Methods Eighteen edentulous patients with severe resorption of residual ridge were treated with semi-anatomic oeelusal dentures or lin- gualized occlusal dentures for three months. Then they changed to wear another type of oeelusal dentures for three months too. The satisfac- tion was assessed with satisfaction questionnaires and the masticatory efficiency was measured after each denture was worn for one and three months respectively. Results Compared with semi-anatomic occlusal dentures,the stability of lingnalized occlusal dentures was sig- nificantly better （P 〈 O. 01 ）. There was no significant difference in mastieatory efficiency and mastieatory period time between [ingualized occlusal dentures and semi-anatomical occlusal complete dentures（P 〉 0.05）. Grinding time of wearing lingualized occlusal dentures was less than that of semi-anatomic occlusal dentures. Conclusions Lingualized occlusal dentures can improve the performance of dentures by enhancing their stability and comfort for edentulous patients with severe resorption of residual ridge.
