This study compares the sizes of patients' edentulous arches with the shapes of a range of disposable stock trays from one manufacturer. In many dimensions there is considerable discrepancy between the two. It is concluded that, even with tray modification, it is almost impossible to obtain an accurate impression of the shape of the all-important sulcus regions. Such a conclusion emphasises the importance of obtaining further impressions in special trays which are modified appropriately.
本研究比较了患者无牙颌弓的尺寸与某一制造商一系列一次性成品托盘的形状。在许多维度上，两者之间存在相当大的差异。得出的结论是，即使对托盘进行修改，几乎也不可能准确印出极为重要的龈沟区域的形状。这一结论强调了使用经过适当修改的特制托盘获取进一步印模的重要性。
