金属基托全口义齿不同排牙方式对初戴时期语音功能影响的临床评价

The clinical evaluation on voice features between two different teeth arrangement methods of the complete metalbased denture

目的:通过对2种不同排牙方式的金属基托全口义齿初戴时期语音功能进行临床评价,分析金属基托排牙方式对发音的影响。方法:以患者主观自评和客观的汉语语音清晰度方法,分别测试传统排牙方式和个性排牙方式的金属基托全口义齿在初戴当天和戴牙1周后的语音功能,并进行统计学比较。结果:义齿初戴时,两组患者均感觉不适,初戴1周后,第二组感觉明显优于第一组。语音清晰度测试结果为义齿初戴1周后,第一组94.57%±1.45%,第二组96.32%±2.14%,两组间差异有统计学意义(P<0.05)。不达标字统计分析结果,两组均为爆破音为主,唇齿音其次。戴用1周后爆破音和唇齿音不达标字第二组(56.9%;23.2%)明显少于第一组(59.6%;24.5%),P<0.05。结论:个性排牙的全口义齿仿真自然牙,语音功能优于传统排牙的义齿。临床上,应充分发挥其优势。

Objective： To evaluate the voice features of two different teeth arrangement methods on the complete denrare of metal base. Methods： Test voice features of the traditional teeth arrangement and personal teeth arrangement on the complete denture with metal base when denture was used at the beginning and then at 1 week by the patient＇s self-judgement and the measurement of Chinese intelligibility. Results： At the beginning of placement, the patients in both groups all felt uncomfortable with denture. After one week, the patients in second group with personal teeth arrangement felt much better than those in first group with traditional teeth arrangement. The result of the first group is 94.57%＋_1.45%. The result of the second group is 96.32% ±2.14%. The data of Chinese intelligibility showed significant differences between two groups after using denture 1 week （P〈0.05）. The analysis of non-compliance words illustrated plosive-based and labiodental-followed. After using denture 1 week, the plosive and labiodental of non-compliance words in the second group were 56.9% and 23.2% respectively. It＇s lower than which in the first group（59.6%, 24.5%）. The data of Chinese intelligibility showed significant differences between two groups （P〈 0.05）. Conclusion： The complete denture with personal teeth arrangement was shown to be similar to natural teeth. Its voice features were better than denture with traditional teeth arrange- ment. We should give full play to its strengths in clinical practice.
