在一项受试者内交叉临床试验中，对15名完全缺牙受试者佩戴下颌固定假体和长杆可拆卸种植体支持假体进行了心理测量和功能测量。在本文中，心理测量评估的结果。8名受试者首先接受固定桥，7名接受可拆卸式桥。在佩戴假肢至少两个月后，受试者对心理测量量表做出反应，该量表测量了他们对与假肢相关的各种因素的看法。他们还咀嚼测试食物，同时记录咀嚼活动。然后更换假体并重复手术。在研究结束时，患者被要求选择他们希望保留的假体。在视觉模拟量表上，患者对两种类型的种植体支持假体的评分显著高于其原始传统假体的所有测试因素，包括总体满意度。然而，除了咀嚼胡萝卜、苹果和香肠的困难外，两种种植体支持的假体之间没有统计学显著差异。对于这些食物，固定假体的评分更高。受试者对类别量表的反应与他们对视觉模拟量表的反应一致。这些结果表明，虽然患者发现固定桥咀嚼较硬的食物明显更好，但他们对两种类型的假体的总体满意度没有差异。
In a within-subject cross-over clinical trial, psychometric and functional measurements were taken while 15 completely edentulous subjects wore mandibular fixed prostheses and long-bar removable implant-supported prostheses. In this paper, the results of a psychometric assessment are presented. Eight subjects first received the fixed bridge and seven the removable type. After having worn a prosthesis for a minimum of two months, subjects responded to psychometric scales that measured their perceptions of various factors associated with prostheses. They also chewed test foods while masticatory activity was recorded. The prostheses were then changed and the procedures repeated. At the end of the study, patients were asked to choose the prosthesis that they wished to keep. Patients assigned significantly higher scores, on visual analogue scales, to both types of implant-supported prostheses than to their original conventional prostheses for all factors tested, including general satisfaction. However, no statistically significant differences between the two implant-supported prostheses were detected except for the difficulty of chewing carrot, apple, and sausage. For these foods, the fixed prostheses were rated higher. Subjects' responses to category scales were consistent with their responses to the visual analogue scales. These results suggest that, although patients find the fixed bridge to be significantly better for chewing harder foods, there is no difference in their general satisfaction with the two types of prostheses.
