Relining is the resurfacing of a denture with a new material. This can be achieved in one of two ways, direct (chairside) or indirect (lab).
Cold cured acrylic or tissue conditioner are used, but are not very durable and are only a short term solution. The fitting surface of the denture is cleaned, roughened, and slightly reduced. The flanges are trimmed (to reduce danger of over extension) and the undercuts removed. The new relining is then mixed and applied to the fitting surface.The denture is inserted and the patient asked to bite gently on the denture to ensure that the occlusion is not altered by the procedure. Border moulding can then be carried out.The denture is kept in situ for about 5 minutes after which it is removed and carefully examined. If cold cured acrylic was used the denture is placed in a hydroflask to complete the curing and to reduce the possibility of porosity. If tissue conditioner was used then the excess should be trimmed away and re-inserted. This should be carried out a couple more times to make sure the all of the excess is removed.
The result is a better fitting denture due to its new and well adapted fitting surface.
The fitting surface is cleaned.The undercuts are removed and the flanges are shortened. Minor defects and extensions can be corrected with self cured acrylic such as Total. A wash impression is then taken on the fitting surface of the denture with impression paste, with the patient in light occlusal contact.In the laboratory the technician's replace the impression paste with heat cured acrylic which is more durable than the materials used for direct relines.
Relines lead to an increase in palate thickness. When a number of relines have been carried out a rebase can be carried out to reduce this palatal thickness.
An Overdenture is a denture that uses precision dental attachments to hold the denture down. The overdenture attachment can be placed in tooth roots that have been saved, or placed into dental implant which have been placed to receive them.
Smoking can lead to tooth staining, gum disease, tooth loss and in more severe cases mouth cancer.
Most people are now aware that smoking is bad for our health. It can cause many different medical problems and, in some cases, fatal diseases. However, many people don’t realise the damage that smoking does to their mouth, gums and teeth.
Smoking can also lead to gum disease. Patients who smoke are more likely to produce bacterial plaque, which leads to gum disease. The gums are affected because smoking causes a lack of oxygen in the bloodstream, so the infected gums fail to heal. Smoking causes people to have more dental plaque and for gum disease to progress more rapidly than in non-smokers. Gum disease still remains the most common cause of tooth loss in adults.
