An overdenture is a removable dental prosthesis that covers and rests on one or more remaining tooth roots. A removable partial denture is a dental prosthesis that replaces some teeth and is built around existing natural teeth. Both the overdenture and the removable partial denture may be connected to the remaining tooth roots or remaining natural teeth with anchors made of metal or plastic. These connections improve stability and the retention of both prostheses.
Dentures Cost
Processing a denture is usually performed using a lost-wax technique whereby the form of the final denture, including the acrylic denture teeth, is invested in stone. This investment is then heated, and when it melts the wax is removed through a spruing channel. The remaining cavity is then either filled by forced injection or pouring in the uncured denture acrylic, which is either a heat cured or cold-cured type. During the processing period, heat cured acrylics—also called permanent denture acrylics—go through a process called polymerization, causing the acrylic materials to bond very tightly and taking several hours to complete. After a curing period, the stone investment is removed, the acrylic is polished, and the denture is complete. The end result is a denture that looks much more natural, is much stronger and more durable than a cold cured temporary denture, resists stains and odors, and will last for many years.
Hypochlorite cleansers have a disinfectant action and they remove non-viable organisms and other deposits from the surface, but they are not very good at eliminating calculus from the denture surface. Immersing dentures in a hypochlorite solution for more than 6 hours occasionally will eliminate plaque and heavy staining of the denture. Furthermore, as microbial invasion is prevented, the deterioration of the soft lining material does not occur.[32] Although, corrosion of cobalt chromium has occurred when hypochlorite cleansers have been used and they may also result in the fading of the acrylic and silicone lining, but the softness or elastically of the linings are not greatly changed.[35]
Like a bridge, partial dentures rest on surrounding teeth to fill in the gaps where one or more teeth are missing. But unlike a bridge, partial dentures are fully removable by the wearer. Partials are affordable alternatives to other types of dental prosthetics and are custom-made to blend in with each patient’s natural teeth. It takes a little time to adapt to new partials, but many people find that they reclaim much of their original function and aesthetics with partial dentures in place.
Conventional full dentures are used to replace a full set of teeth either on the upper or lower jaw. When all of the patient’s natural teeth have been removed and the gum tissues have healed, conventional full dentures may be placed in the mouth. In between, the patient may be fitted with an immediate denture that can be inserted on the same day the teeth are extracted. Using immediate full dentures is beneficial for the patient because this means that he does not have to go without teeth for a certain period. Readjustment of the dentures will have to be made after several months because the supporting bone will reshape as it heals and this will cause the denture to loosen.
