摘要:

目的  探索Hawley保持器与热压膜保持器两种常用的正畸保持器对成人正畸患者中文语音发音的影响。方法  采用临床随机对照的形式,将20名研究对象随机分为两组,每组10名,A组戴用Hawley保持器,B组戴用热压膜保持器。分别于戴入保持器前(T0)、刚戴入保持器时(T1)、戴入后1 d(T2)、戴入后1周(T3)、戴入后1个月(T4)共5个时间点进行5次中文语音音频资料的采集,运用Praat 5.4.21语音分析软件和SPSS 19.0对采集的语音资料进行语音参数分析。结果  两种正畸保持器均能引起单元音/e/、/i/、/ü/,辅音/s/、/f/、/x/、/t/、/j/和/q/的语音参数变化,其中Hawley保持器对/i/、/ü/、/s/音的影响持续时间可达1个月以上,热压膜保持器对语音的影响多可在1个月内恢复正常发音。结论  两组正畸保持器均可影响成人正畸后中文语音的发音,其中Hawley保持器对语音的影响更大,而热压膜保持器对语音的影响多可较快恢复正常。

Abstract:

Objective  This study investigated the influence of Hawley retainer and vacuum-formed retainer on the articulation of Chinese speech of adult orthodontic patients. Methods  A total of 20 volunteers were recruited in this randomized controlled trial in accordance with the inclusion criteria. Participants were randomly distributed into two groups, namely, the Hawley retainer group and the vacuum-formed retainer group. Speech performance was evaluated at the following time intervals: before wearing retainers (T0), immediately after wearing both upper and lower retainers (T1), 24 h later (T2), 1 week later (T3), and 1 month later (T4). The phonetic parameters were acquired through the use of computer-based voice analysis software Praat version 5.4.21, and the final data were analyzed using SPSS 19.0. Results  Both retainers can influence the phonetic parameters of vowels /e/, /i/, and /ü/ and consonants /s/, /f/, /x/, /t/, /j/, and /q/. However, the Hawley retainer showed a more remarkable effect on the articulation of Chinese speech, and the distortion of /i/, /ü/, and /s/ sounds can last for more than 1 month. Nevertheless, the recovery period of the patients’phonetic function in the vacuum-formed retainer group was within 1 month. Conclusion  Both retainers can induce distortion of some Chinese vowels and consonants in the speech of adult orthodontic patients, but the Hawley retainer can more significantly influence the articulation of Chinese speech than vacuum-formed retainer.
