项目摘要

A randomized controlled parallel clinical trial at the two hospitals was conducted from April 2004 to July 2006. The permuted block method of randomization with a block size of four consisting of,. treatment with RLD by a senior clinician (SC), treatment with RLD by a junior clinician (JC), treatment with ARD by a SC and treatment with ARD by a JC, in a combination of treatments and clinicians groups (treatments=ARD and RLD ; clinicians=JC and SC) was used. Outcomes: a) numbers of sore spots ; b) duration of wearing dentures; c) pain perception ; d) satisfaction ratings; e) masticatory performance ; f) mandibular movement at the lower incisal point during chewing Results Seventy-four patients who had been consecutively sampled (aged 53 to 89 yrs) were randomized for this trial. No significant differences were observed in any of the baseline characteristics between the ARD and RLD. Significant differences in the number of sore spots in the support and border areas for the mandibular mucosa were clearly observed between the RLD and ARD groups. In contrast, there were no differences in the number of sore spots in the frenum area. Furthermore, significant differences in the number of sore spots in the support and border areas for the maxillary mucosa were definitely observed between the JC and SC groups. The RLD wearers were able to wear their dentures an additional day longer than the ARD wearers. Significant differences between the RLD and ARD groups in the maxillary and mandibular pain ratings were observed. There was no significant difference in the masticatory performance and mandibular movement at the lower incisal point during chewing between the ARD and RLD groups.

2004年4月至2006年7月在两家医院进行了随机对照平行临床试验。随机化的排列块方法，块大小为4，由，组成。RLD由高级临床医生（SC）治疗，RLD由初级临床医生（JC）治疗，ARD由SC治疗，ARD由JC治疗，采用治疗和临床医生联合组（治疗=ARD和RLD；临床医生=JC和SC）。结果：a)痛点数量；B)假牙佩戴时间；C)疼痛感知；D)满意度评分；E)咀嚼性能；f)咀嚼时下颌下切点的运动结果74例连续取样的患者（年龄53 ~ 89岁）被随机分配到本试验中。在ARD和RLD之间没有观察到任何基线特征的显著差异。RLD组和ARD组在下颌黏膜支持区和边界区溃疡点数量上有明显差异。相比之下，在系带区疼痛点的数量没有差异。此外，JC组和SC组在上颌黏膜支持区和边界区溃疡点数量上也有明显差异。RLD佩戴者比ARD佩戴者能多戴一天假牙。RLD组和ARD组在上颌和下颌疼痛评分上存在显著差异。在咀嚼过程中，ARD组和RLD组的咀嚼性能和下颌下切点运动无显著差异。
