Hi, I'm a young(er) dentist who is lacking in removable knowledge. What are the most important details that you as a denture technician need to know from the dentist?

1) And what are your thoughts on metal RPD vs flexible?

2) The local lab I use--patients complain that their flexible partials start becoming smelly pretty quickly just after a few years.. Is there a reason why?
There is another option that is called Hybride that combine the best of both. In cast partials, people do not like metal showing but it can be laser welded to add teeth, relined and it is a tooth born appliance. Years ago as I remember flexy partial were invented for people with allergic reaction to the metal. They are tissue born appliances, can not be relined and limited repairs most is not permanent ,there is no one option for all. Hybride does cover both satisfaction in aesthetics of the flexy and function of the cast. Yes there is no bond between the flexy material and the teeth just mechanical where in the cast there is a chemical bond between the tooth and the pink acrylic portion of the partial.

They are porous which creates smelly stains, can’t use rest seats therefore ridge takes a pounding.
If you Need to grind tooth heavy you are eliminating mechanical retention which is needed here.
Pain in the ass to adjust lab or chairside. If patients needs another tooth added in the future sometimes you will need to make a new one.We sometimes add with acrylic but don’t guarantee it.
I would recommend not doing these if there is only one single tooth on anterior specially lower ants.they usually pop off due to the lack of material, hell I would t do them at all

If you want it, I have a trick for addign to many them. It's enough to get them till another something gets made at least. Most will last for years, but I make zero promises.
