title: Disposable trays for complete denture construction: a dimensional study of a type frequently used in the UK and of its suitability for the edentulous population.
abstract: 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.
