Usually when bone, tooth structure, or soft tissue touches the wall of a double-arch tray, you can expect your tray will distort and you may have to adjust your restoration or be faced with a remake.

We suggest you pay extra attention to the occlusal table width of your double-arch trays.

The average facio-lingual distance from soft tissue to soft tissue for most patients is 16 mm. In contrast, many of the trays on today's market have an occlusal table width of 14 mm. In reality, this is like trying to place a size 9 foot into a size 7 shoe.

A wide occlusal tray is desirable. From quadrants to full arch triple trays selection and modification can yield predictable results.

Look for trays with an occlusal table width of 20 mm. One such set of trays is made by WOW/NEO. WOW/NEO #2203 trays work very well for most quadrant impressions

Here are a few suggestions:

Try the tray in your patient's mouth prior to tooth preparation or anesthetizing. Carefully examine for any source of impingement.

If hitting the retro-molar pad area, use a full double arch tray, such as WOW/NEO #2205, which does not have any bars in the retro molar pad area. If you do not wish to take full arch impressions, you could still use this tray and only load one half of it with impression material.
