摘　　要：目的:对唇腭裂患者术后采用不同基托设计的双重牙列修复前后的咀嚼效能和语音效果进行评价,判断其修复效果。方法:选择6例腭侧孔腔在1cm×1cm以内,或腭部隐裂患者,分别给予双重牙列修复,一种是颊侧基托和假牙列的双重牙列,另一种是颊侧基托和假牙列并在腭侧作基托,覆盖孔腔和隐裂。分别在初戴前及初戴后、初戴1个月后行咀嚼效能和语音测试,采用SPSS11.0软件包对资料进行配对t检验。结果:2种设计方式的双重牙列初戴后,1个月咀嚼效能显著提高(P<0.01),被检敏感音之间的差异主要集中在第2共振峰(F2)和第3共振峰(F3)上(P﹤0.05)。2种设计之间比较,咀嚼效能和语音检测均无显著差异。结论:2种设计方法均可显著提高咀嚼效能,改善语音功能。唇腭裂患者如腭侧孔腔很小,在1cm×1cm以内,或腭部隐裂患者,不必行腭侧基托设计,语音、咀嚼效能和美观同样得到提高和改善。PURPOSE： To evaluate the masticatory efficiency and phonetics in patients with cleft lip and palate before and after double dentition denture treatment, and determine the results of the treatment. METHODS： 6 patients who had cleft lip and palate with defect smaller than 1cm×1cm or submucous cleft palate were selected to undergo double dentition denture treatment. Two kinds of base design were used. One was with artificial teeth and buccal base only. The other was with artificial teeth and base on both the buccal and palatal sides. Masticatory efficiency and phonetics effect were tested before and immediately after treatment and 1 month after treatment. The data were analyzed using SPSS11.0 software package for paired t test. RESULTS： There was statistically significant difference in masticatory efficiency, before and immediately after treatment and 1 month after treatment （P〈0.01）. As for phonetics , there was statistically significant difference on F2 and F3 before and immediately after treatment as well as 1 month after treatment （P〈0.05）. While there were no statistically significant difference both on masticatory efficiency and phonetics between the two kinds of design. CONCLUSION： Both the two kinds of treatment can improve the masticatory efficiency and phonetics effectively. It is not necessary to use the palatal base when the defect is smaller than 1cm×1cm or submucous cleft palate present.
