What is Denture Relining?
Over time the shape of your gums and the bones that support the dentures can change, which means they may no longer fit properly. Relining is a method of adjusting the internal part of the base of the dentures with an acrylic resin to correct their fit. This technique doesn't alter the appearance of the dentures; it simply adapts the base to suit the changing shape of your gums. The Clinical Dental Technician will take an impression of your gums using your dentures, so you will be without them whilst the new base is added.
The procedure involves:
- Removing some of the plastic from the fitting surface of your denture
- Placing a layer of soft impression material onto this trimmed surface
- Repositioning inside your mouth to take an impression of your gums
- Using this accurate impression to create a new hard or soft base
What are the advantages of denture relining?
Denture relining allows the fit of your dentures to be improved, without the need for replacing them with a new set. They will fit much more securely, so you won't have to worry about them falling out or moving when you speak and eat. Relining also helps the dentures to last longer and improves your oral hygiene, as food is less likely to become trapped under your dentures, which can happen if they are too loose.
In many cases, patients no longer need to use denture adhesive.
Soft liners are made from a soft flexible silicone material and may need to be re-done every year. They are used if the mouth cannot tolerate a hard denture base and are far more common in the lower jaw.
Hard relines are a permanent solution compared to a soft reline and are made from the same material as the denture base. A hard reline will usually be used if your mouth is healthy and can support a new denture base.
What's the difference between relining and rebasing?
Rebasing involves replacing the entire base of the denture, rather than just altering its fitting surface. It is much less common than relining.
