DISPOSABLE TRAYS FOR COMPLETE DENTURE CONSTRUCTION - A DIMENSIONAL STUDY OF A TYPE FREQUENTLY USED IN THE UK AND OF ITS SUITABILITY FOR THEEDENTULOUS POPULATION

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 impossibl e to obtain an accurate impression of the shape of the all-important s ulcus regions. Such a conclusion emphasises the importance of obtainin g further impressions in special trays which are modified appropriatel y.
