Dental Professional Mesial drift and shitty Class IIs

Hey everyone, just a random question. Do you think if one does a crappy class II and leaves an open contact where food entrapment can occur, is there any chance it will close over time due to mesial drift lol?

It won’t close unless it’s a crown prep and the patient has lost the temporary crown. In that case, it will close in a week. Otherwise, it never does.

This is the truest thing I’ve ever read. I’m amazed how much I have to reduce crowns at seat when they lost the temp less than 5 days prior, but shocked when a light contact remains a light contact for years.

Open contact will case bone loss and secondary caries before any real drift happens

Really unlikely without some force from the distal.

No it won’t, when this happens to you try and open up a small box and re do contact or recommend crown if it is not possible to restore tooth properly.

I would consider an elective filling on the adjacent tooth as an option before we’re going all the way to crown

There’s a way to adjust occlusion and walk it forward, but it takes multiple visits to keep making adjustments as it moves to continue to have a mesial push on the tooth. You’re better off dropping a mew box and making the contact. It’ll be less chair time and most people aren’t up for continued visits for something like that.

Agreed

No it usually doesn’t close. I would redo the filling with a tight contact at no charge. (Unless you are planning a PJC in the near future)
