摘要
目的:对比分析无牙患者对传统非解剖型人工牙与改良长正中型人工牙制作的全口义齿满意度和全口义齿咀嚼效能的影响。方法:选择60例牙槽嵴吸收严重的无牙患者,随机分为2组,分别采用传统非解剖型和改良长正中型人工牙制作全口义齿,在戴用义齿1个月和3个月后,测试无牙患者对2种全口义齿的满意度,同时通过吸光度法测定咀嚼效率,比较2种型全口义齿咀嚼效能的异同。采用SPSS11.0软件包对数据进行统计学分析。结果:2种不同型全口义齿在美观、语音、舒适度方面均无显著差异;而长正中型组的咀嚼功能显著优于非解剖型组。结论:对于牙槽嵴严重吸收的无牙患者,应用改良长正中型有利于患者在咀嚼过程中稳定使用义齿,提高咀嚼效能,且可提高患者的满意度。
PURPOSE： To compare and analyze the effect of unanatomic and long centric complete occlusal denture on the satisfaction of edentulous patients and mastication.METHODS： Sixty edentulous patients with severe resorption of residual ridge were treated with unanatomic occlusal and long centric occlusal complete dentures.One month and three months after wearing dentures,the satisfaction evaluation from edentulous patients for the different complete dentures was analyzed,and the masticatory stroke was tested,the masticatory efficiency of the two complete dentures was detected by light absorption method.SPSS 11.0 software package was used for data analysis.RESULTS： Compared with unanatomic occlusal dentures,appearance,pronunciation and comfort of long centric occlusal denture wearers were not significantly different for one and three months（P〈0.05）.But the masticatory function of long centric occlusal denture wearers was significantly better than anatomic occlusal denture wearers（P〈0.05）.CONCLUSIONS： Modified occlusion is feasible for restoration of masticatory efficiency of edentulous patients using long centric occlusal complete dentures,and they are more acceptable by edentulous patients with severe resorption of residual ridge.
