How to spot Less-Than-Perfect dental impressions

Presence of drag marks.

To avoid these, wait until the material is fully set before removal and extract it straight down for upper impressions and straight up for lower ones.

Bad impression #2

Improperly mixed material.

Blend the putties until a uniform color is achieved, without any streaks. Perform this step right before placing the material in the trays.

Bad impression #3

Movement of teeth during the process.

If the tray shifts, it can distort the impression. Securely hold the tray to prevent movement for a reliable impression.
