中文摘要
目的 比较快慢速扩弓治疗对鼻腔结构改建的影响。方法 选取牙弓狭窄者40例,随机分为2组,术前和术后分别拍摄锥形束CT,比较治疗前后鼻腔结构的变化。结果 快速扩弓组较慢速扩弓组基骨弓宽度和鼻腔骨性结构打开量大;上颌骨宽度和鼻腔软组织变化无明显差异。结论 快速扩弓治疗更有益于改善鼻腔功能。
英文摘要
ObjectiveThis study aims to compare the effects of fast and slow expansion on nasal cavity structure.MethodsA total of 40 patients were selected and randomly divided into two groups. Cone-beam computer tomography (CBCT) was obtained before and after surgery and used for comparing the changes in nasal structure before and after treatment.ResultsFast expansion had resulted in greater changes in the basilar and nasal bone arch extension structures than slow expansion. No significant difference at maxillary width and nasal parenchyma.ConclusionRapid expansion therapy has more beneficial effects on nasal function.
