A multi-centre randomized clinical trial is under way at 14 university dental schools in Germany to compare prosthodontic treatments for the shortened dental arch (SDA). One of the aims of this pilot-study was to measure the effect of two treatment options of the SDA on oral health-related quality of life and on the Research Diagnostic Criteria (RDC) for temporomandibular disorders (TMD). Thirty-four patients participated in the pilot-study. Inclusion criteria were: all molars were missing and the presence of at least both canines and one premolar in each quadrant. Participants were randomly assigned to receive either removable partial dentures including molar replacement (RPD_group) or retain a premolar occlusion (PROC_group). The Oral Health Impact Profile (OHIP-49) and the RDC for TMD were completed by participants before treatment (pre-treatment), 6 weeks (6 wks), 6 months (6m) and 12 months (12 m) after treatment. At the 12-month follow up, data of 10 women and 11 men (mean age: 62 +/- 10 years) were available. Medians of the OHIP total-scores were as follows: RPD (n = 10), 43.5 (pre-treatment), 18.2 (6 wks), 13.3 (6m), 14.7 (12 m). PROC (n = 11): 31.8 (pre-treatment), 27.1 (6 wks), 8.8 (6m), 8.3 (12 m). Significant differences were shown for RPD_group between pre-treatment and 6m/12 m and for PROC_group between pre-treatment and 6m. There were no significant differences between treatment groups at any time. Within each group, an improvement of life-quality was observed. No significant difference could be reported between the two therapy concepts. This may be due to the low sample size within the pilot study.
德国14所大学牙科学院正在进行一项多中心随机临床试验，以比较针对短牙弓（SDA）的修复治疗方法。这项初步研究的目的之一是测量SDA的两种治疗方案对口腔健康相关生活质量以及颞下颌关节紊乱病（TMD）研究诊断标准（RDC）的影响。34名患者参与了该初步研究。纳入标准为：所有磨牙缺失，且每个象限至少有两颗尖牙和一颗前磨牙。参与者被随机分配接受包括磨牙替代的可摘局部义齿（RPD组）或保留一颗前磨牙咬合（PROC组）。参与者在治疗前（治疗前）、治疗后6周（6周）、6个月（6个月）和12个月（12个月）完成口腔健康影响量表（OHIP - 49）和TMD的RDC。在12个月的随访中，获得了10名女性和11名男性（平均年龄：62±10岁）的数据。OHIP总分的中位数如下：RPD组（n = 10），43.5（治疗前），18.2（6周）, 13.3（6个月），14.7（12个月）。PROC组（n = 11）：31.8（治疗前），27.1（6周），8.8（6个月），8.3（12个月）。RPD组在治疗前与6个月/12个月之间以及PROC组在治疗前与6个月之间显示出显著差异。在任何时间点，治疗组之间均无显著差异。在每组中，生活质量均有改善。两种治疗方案之间未报告有显著差异。这可能是由于初步研究中的样本量较小。
