The aim of this survey was to determine how a sample of dentists working in general dental practice in the UK sought to restore the mouths of patients who had shortened dental arches (SDAs).
A survey was conducted over a period of six months on four commercial dental laboratories. Cases of SDAs comprising the anterior teeth and 2 to 4 premolars were examined; dental prescriptions were scrutinized and a special data collection form was completed accordingly.
A total of 140 SDA cases were examined. Most of these cases were for mandibular SDAs (88.6%). Of the recorded SDA cases, 67.2% were restored by cobalt-chromium based removable partial dentures (RPD); 25.7% were extended by acrylic-resin based RPDs; implants were provided to restore 8 SDA cases (5.7%); and only two SDA cases (1.4%) were extended by cantilevered fixed bridges. Neither the gender of the patient ([Chi (2)= 4.19, p>0.05) nor the length of the SDA ([Chi (2) = 6.51, p>0.05) influenced the choice of prosthesis to be implemented.
It would appear from the results of this survey that among the different restorative treatment options for SDA, the RPD was the most popular treatment option for dentists surveyed in this UK study. Extending the SDA by either an implant-supported prosthesis or cantilevered fixed bridges did not appear to be a popular choice of treatment.
本调查旨在确定英国普通牙科实践中工作的牙医样本如何试图修复患有短牙弓（SDA）的患者的口腔。
在四个商业牙科实验室进行了为期六个月的调查。检查了包含前牙和 2 至 4 个前磨牙的 SDA 病例；仔细审查了牙科处方，并相应地完成了特殊数据收集表。
共检查了 140 个 SDA 病例。这些病例大多为下颌 SDA（88.6%）。在所记录的 SDA 病例中，67.2%通过钴铬基可摘局部义齿（RPD）修复；25.7%通过丙烯酸树脂基 RPD 扩展；为 8 个 SDA 病例提供了种植体修复（5.7%）；只有两个 SDA 病例（1.4%）通过悬臂固定桥扩展。患者的性别（[Chi（2）= 4.19，p>0.05）或 SDA 的长度（[Chi（2）= 6.51，p>0.05）均不影响所实施假体的选择。
从这项调查的结果来看，在 SDA 的不同修复治疗选择中，RPD 似乎是这项英国研究中调查的牙医最受欢迎的治疗选择。通过种植体支持的假体或悬臂固定桥扩展 SDA 似乎不是一种受欢迎的治疗选择。
