A denture reline is a material used to line the denture in the side that touches the skin. ( intaglio surface of denture) When you have a new denture, skin rubbing and pain are normal. This is because the pressure on the skin from the denture causes inflammation and swelling. This is more severe after an extraction or oral surgery. After wearing the denture for awhile, this usually improves. The skin heals and toughens. This is why most new dentures start with a soft reline placed inside of them. It allows the skin to heal and fits the denture to the changing shape of the mouth. Types of denture reline the inside part of the denture that touches the skin is lined with different materials. The main difference between the materials is how soft they are.
There are 4 basic groups of denture reline material:
- Temporary soft reline This is a very soft and temporary bandage or cushion material. Used most often to fit dentures on the day of extractions or oral surgery, this liner is very flimsy and can be removed with finger pressure. It usually lasts for a few days to a few weeks. At Midtown Dentistry we like to use COE COMFORT.
- Temporary rigid reline This is a medium strength, resilient, semi-soft reline. It is used inside dentures for a period of about three months and provides a good fit and shape while the gums heal. At Midtown Dentistry we like to use COE SOFT.
- permanent soft reline This is a permanently soft material that is made as the inner part of a permanent denture. The idea behind it is to serve as a cushion for thin gums that suffer when dentures press on them. These type of dentures have a shorter life-span and are not meant for everyone – but for the specific problems of patients with “knife ridge” types of jaw bones. Only dentists with significant experience in denture construction can choose this kind of treatment successfuly.
- permanent hard reline This is used to “update” and old denture. As the gums shrink, dentures lose their fit. If the teeth are still clean and usable, the denture can have part of it removed and re-made using a reline with a hard plastic that makes it fit the new shape of the gums and bone.
