Over Dentures

Over dentures are removable dentures built-over anchors. This type of conventional dentures resembles complete dentures. The difference is that the teeth in over dentures are not extracted. They use one or more teeth or dental implants for support. Dentists suggest this type of denture if the gum tissues and roots of a patient's remaining teeth are still strong. The remaining teeth are resculpted and covered with metal caps to stop future decay.

Maintenance of a denture on the jawbone ridge or alveolar ridge is important because it facilitates denture stability. Preservation prevents from becoming loose during speaking, eating and other activities. The body has a function to maintain only structures with immediate value. As for alveolar bone, the body recognizes the purpose of it, which is to hold tooth roots. If it no longer supports a tooth root, resorption takes place. This process simply means shrinkage. Reporption progresses at varying rates to different persons. It is rapid within the first year of loosing a tooth then progresses at a slower pace. In over dentures, pressure is reduced to the portions of the alveolar ridge. It also helps reduce shrinkage of the surrounding bone.

Over dentures are slightly more bulky but have the advantage of a natural feeling and providing a greater stability during chewing and speaking. It is more stable and retentive. It has a psychological advantage of still having teeth. Over dentures also does not need to be frequently relined because gums and jawbone recede less.

Generally this type of denture is more expensive. It costs more and requires more dental appointments until the procedure is completed. Frequent maintenance exams are needed because of the risk of decay to the roots of the remaining teeth. Oral hygiene is important to prevent gum disease. A fluoride gel must be place in the denture everyday in the area where the roots are. The over denture supporting teeth may be cleaned every three to six months so that a fluoride supply is replenished.
