A radiographic examination confirmed multiple caries on the teeth of both arches, as well as periodontal disease with generalized moderate-to-severe horizontal bone loss (Figure 5).

The tray should have a full extension similar to that of a complete denture in the corresponding region (Figure 8).

This could prevent the denture from displacement due to the movement of the muscle during its function (Figure 9).
No tray shows through the impression.
