They can be copied, but there will always be some degree of distortion
and loss of surface detail with each successive generation of copy.

The traditional way would be to make an impression of the model (just
as an impression of the natural teeth would be) and pour it up in dental
stone.
Now CAD-CAM technology is coming into dentistry--models can be copied,
manipulated, etc. with optical scans and milling, as is done in
Invisalign orthodontic technology.

Not just any impression, think cast duplication for refractory cast
construction for RPD frames. Reversible hydrocolloid in a flask.
While not perfect, it's pretty damn good.
Again, die stone.

Why duplicate casts anyway ?
Just make new ones.

I agree, but I got the feeling this wasn't a clinical question.

I've got plaster models from 1996 and want a copy of current models to see
how much my mouth has changed.
Didn't realize dental modeling had gone high tech. The models my dentist
has for me appar to be plaster. I'll ask.

Just get your dentist to make you a new set for yourself.
Easier and more accurate than dupes.
Be prepared to pay a nominal fee.

Plaster is never used in my practice. Die stone only.

I still have some impression plaster around. Oh, and when I started
out I used copper band impressions and impression compound for C&B.

With some rubber base I would hope. <hehe>
Yeah, know that technic too, when was the last time
you used it ? For me since school, not once, but it
is a viable technic.

Re: Is it possible to make exact copies of plaster dental models?
I did a few copper bands with compound and relined with Permalastic back in
the 1980's. Optical impressions this century.

Re: Is it possible to make exact copies of plaster dental models?
Can someone tell me exactly what was done with this copper band technique?
I hear about it all the time, but never learned about it in school.
