Removable dentures, as their name implies, are prostheses that can be removed. These are the dentures in everyday language.
Removable dentures are a more economical choice that is used when fixed prostheses exceed your budget. Also know that in any case, you can still do without it, by placing implants, in case of unilateral posterior, or bilateral for example, or ask a fixed bridge if there is an opportunity to bridge from one tooth to another.
There are two types of removable prostheses: partial dentures and total removable dentures. You will have a partial denture if you have teeth left; the prosthesis will then replace the missing teeth among the remaining teeth. The total prosthesis, for its part, is used, in case of total delivery, to replace all the teeth (up or down) that you miss.
There are two types of manufacturing for removable prostheses (partial or total). They can be made either entirely of resin, or of resin and metal. I would like to say to you very sincerely that the prostheses which are made completely in resin are prostheses of lesser quality.
They are fragile prostheses and they must be realized and proposed only for a short duration, while waiting for the definitive prosthesis. This is called a temporary or transient prosthesis. I will explain why you should never accept a removable prosthesis completely made of resin as a permanent prosthesis.
Even if you came across the best dentist working with the best prosthetist, for me totally removable dentures will always be fragile prostheses regardless of their competence. They are only to be used temporarily while waiting for a more solid final prosthesis.
"Why will removable dentures in resin never be definitive prostheses?"
Resin is a soft material, which must always be moist to keep all its flexibility and adapt to your oral cavity. But the resin is also a porous material. Its porosity induces food infiltration. It then becomes breakable; this is due to the drying of the resin which is less in contact with the saliva.
You can see the drying of a resin denture by its rapid fading. The fact of dropping a resin device is then enough to break it in two. I know what I'm talking about: I'm a dental technician and I got a lot of removable resin fixtures for repair. I worked regularly with this material and I know perfectly the defects.
So after all that I have just revealed to you, I hope that I convinced you to opt for a removable metal prosthesis if you chose this type of prosthesis. Thanks, opt for removable metal prostheses, they are stronger and therefore last longer.
Partial removable metal and resin dentures are called stellites.
Total metal prostheses consist of a wire mesh embedded within the resin. This solution is excellent, moreover, I advise you if you have more teeth. It increases the longevity and sturdiness of your denture.
Relining is imminent when the inner morphology of your mouth changes (ie the bone and gum) and your removable device becomes wider. It does not marry your gum anymore. This is where the problems arise. The device is no longer in place, localized pain can occur ... Be careful, because if you encounter such problems, your device needs a rebasage.
This is the solution to a device that no longer holds in the mouth. It is about putting resin back into the void, also called the intrados, created between your gum and your device. After this addition of resin, your device will perfectly marry your gum again as if it were new!
The effect of levitation or suction effect will be restored, it will not fall. Be aware that to properly maintain your device and keep it longer you must rebase your device at least once a year. Indeed, the morphology of your mouth changes constantly, and so you will not escape a rebasage.
Moreover, it is often because people who have a device neglect this annual interview that they end up changing it prematurely. It is this lack of regular maintenance that ends up weakening the device early and causes irreversible damage that will force you to redo it.
Please note that removable resin dentures (partial or total) have a lifespan that does not exceed 10 years.
I also advise you to ask the type of teeth that will be used for the realization of your removable device. There are two types. Porcelain teeth and acrylic teeth. Porcelain teeth are very aesthetic teeth and much stronger than acrylic teeth.
Their only drawback is that they make noise, they just slam. As I said, acrylic teeth are less robust: they wear out quickly and have a life of about 5 years.
A partial denture is usually quite unsightly, because it holds through hooks that are often conspicuous. These hooks can be metal or acetyl (resin color of the tooth). We can offer this last type of hook if you do not want metal hooks, for aesthetic reasons.
The interest of this type of hook is purely aesthetic, because of this, the hooks become virtually invisible. I strongly advise you to accept this kind of resin hook, because its main disadvantage is its fragility. Indeed, it breaks easily because it is resin and not metal.
these hooks are still under a lot of tension because the removable devices are removed daily; they must therefore be made of a robust material. Think about it when your dentist offers you a removable prosthesis.
So opt for metal hooks. You can ask your dentist to shorten the hook a bit, but not too much, because it will lose its effectiveness and your prosthesis may not hold in the mouth. He can also make it less visible by refining it at the end or by asking his prosthetist to place it as close as possible to the base of the tooth.
You should also know that if you break a hook on a partial metal prosthesis (stellite), the device must be completely redone. There is no way to repair a device whose hook is broken.
But you can also be categorical about the fact that you absolutely do not want to hook. Indeed, there is still another solution without a hook. It's attachment. An attachment is a slide or a push-button placed on a fixed ceramic crown on which the partial prosthesis will be clipped.
The attachment is more expensive and is not possible in all cases because it requires the installation of at least one ceramic crown. It is more expensive in the sense of accounting for the cost of the ceramic crown + the cost of attachment which is not negligible. Know that a dental technician bills an attachment about 75 € to the dentists.
Finally, we will finish the paragraph of removable devices on the metal used. The majority of laboratories manufacture their removable with Chrome-Cobalt. But it is also possible to use titanium. Ask your dentist to find out which metal is used, because I will praise the merits of titanium. Its major advantage is its lightness and therefore the comfort it brings to the prosthesis. It makes the prosthesis easier to wear and comfortable.
