Relining is the procedure used in resurfacing of the tissue of a denture base to a person’s gum with new material to make it fit the underlying tissue more accurately. A new acrylic base is placed into the denture to fill the space that exists between the original denture contour and altered tissue contour duplicating the new form of the oral structures of the mouth. A reline can help prevent food from getting under your dentures as well as bring back suction, stability and comfort. Relining of dentures should be done every one to two years to keep them secure and functional.
Rebasing is the procedure to replace the entire denture base with new denture rebase material providing a stable denture. Rebasing can be recommended when the existing teeth of your denture remain in good condition and have not been worn out compared to denture base material. A rebase may be required if your denture has been old, cracked, weak or broken.
Denture reline Vs Rebase: Everything you need to know.
Denture relining is performed to replace the lining of your dentures to make them fit correctly in your mouth because as time passes by, the dentures that once fit snugly in your mouth might begin to loosen up. Your dentures may require regular relining depending on changes that occur when your dental tissue, bone, and mouth throughout your life due to shrinkage. This is a common part of denture maintenance and is crucial to the health of the oral tissues and bone support. The dentures can cause problems such as gum irritation or even cutting them and if left untreated the gums can get infected. Relining the denture will help a lot. However, the number of relines required for your dentures may vary depending on factors such as oral hygiene, loss of weight, teeth, bone, aging, health, alcohol consumption, and certain medications.
- Hard denture reline: Hard denture reline lasts longer than soft resins. However, it might not be as flexible and may not be suitable for patients with sensitive gums. The dentist will remove a layer of plastic from the denture and put a material which is like putty in the denture that will take the shape of your mouth to get an impression afterward.
- Soft denture reline: Many patients prefer soft resin liners as they are much more comfortable and if you have sore spots then it will make wearing dentures very uncomfortable. To create soft reline, they will put pliable silicone material around the dentures that will snugly fit around the tissues of your gums.
Denture rebase is similar to relining the difference in reline Vs rebase is that a rebase is done to remove the denture’s fitting and replaces the entire pink acrylic denture base material with new acrylic instead of just the lightning. The procedure helps to make the denture much more stable without changing the denture teeth as well as improves denture fitting, appearance, strength and vertical dimension. Rebasing a denture can extend the functional lifespan. Denture rebasing is done if the denture no longer fits like before and when the denture teeth have not depreciated compared to the denture base material. Other reasons that might factor on the recommendation of denture rebase include:
- Damaged or broken denture
- Weak or old pink acrylic denture base
- Replacement of the temporary denture to a permanent one
