Summary

Researchers compare two ways to take final impressions for complete dentures: the open mouth technique and the closed mouth technique. Adults who have been missing all their teeth for at least six months and have well-formed ridges join the study. Each person is assigned to one technique, and all dentures are made by the same operator with the same materials. Six weeks after getting their dentures, a blinded examiner checks how well they stay in place, and patients rate their satisfaction.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Two denture impression techniques: open mouth and closed mouth
What this could lead to
If one technique proves better, dentists could adopt it as the standard way to make complete dentures, leading to fewer adjustments and happier patients.
What could go wrong
This is a small, single-center study. Results may not apply to all patients or clinics, and denture fit depends on many factors beyond impression technique.
