目的探讨中腭板式和中空式连接体可摘局部义齿修复对语音功能的影响。方法选择2007年1月至2009年2月南阳市口腔医院收治的上颌肯氏I类牙列缺损患者16例,均分别制作中空式和中腭板式连接体义齿。初戴不同义齿时,统计患者的语音清晰度,并进行对比分析。结果戴中腭板式义齿时,患者的语音清晰度为(87.5±6.1)%,明显高于戴前、后腭杆组成的中空式连接体义齿时的语音清晰度(25.0±4.3)%(P<0.05)。结论与中空式连接体义齿相比,采用中腭板式义齿可较快恢复患者发音功能,发音清晰度明显改善并接近正常。
Objective To explore the effect of removable partial dentures on the speech function in the palatal-plate type and hollow-type connectors. Methods From January 2007 to February 2009, Nanyang Stomatological Hospital, Ikea Kennedy I-dentition defect patients were selected in 16 cases, were made hollow and the palate plate denture. First wearing different dentures, the patient’s voice clarity statistics, and comparative analysis. Results The speech intelligibility (87.5 ± 6.1)% was significantly higher than that of the hollow denture with the anterior and posterior palatal rods (25.0 ± 4.3)% (P <0.05). Conclusion Compared with the hollow type denture, the palatal plate denture can restore the patient’s phonetic function quickly and the articulation clearly improves and approaches to normal.
