Loose nightguards

[nvarras]

I have one account where the nightguard fit the model nicely but they are too loose in the mouth. Anyone know why this is happening? They are using alginate.

Not sure why, maybe it's the alginate...or the stone. However, can you just tighten it up more on the model, or carry it down further to get more of the undercuts?

It’s clear splint and I don’t block out. They’re tight on the model when they leave. come back for a remake and it’s loose on the new model. my guess is something the assistant is doing. just not sure what. Two other docs in the same office and zero issues.

Time for show and tell with an impression results/model pouring class.

If you start trying to change what you're doing as you guess whether it'll be fine or not this time you'll give yourself more problems as you have no way to know if this is a 'loose result model' or a 'tight/proper result model'.

When it comes back loose, does it have grind marks in it? A new model/impression provided?

That's what I was thinking. They adjusted it too much and made it loose.

Ive had this before... get them to check the expiry date on the alginate!
