[...] a composition for the purpose of making of artificial teeth either single double or in rows or in complete sets, and also springs for fastening or affixing the same in a more easy and effectual manner than any hitherto discovered which said teeth may be made of any shade or colour, which they will retain for any length of time and will consequently more perfectly resemble the natural teeth.[8]
Removable partial dentures are for patients who are missing some of their teeth on a particular arch. Fixed partial dentures, also known as "crown and bridge" dentures, are made from crowns that are fitted on the remaining teeth. They act as abutments and pontics and are made from materials resembling the missing teeth. Fixed bridges are more expensive than removable appliances but are more stable.
More modern dentures can be fitted immediately after removal of the last tooth. They are made prior to the operation and allow the user full faculty of their mouth straight after their insertion. However, immediate dentures may lose their fit as the bones and gum shrink during the healing process. Immediate dentures are often used as a temporary solution until conventional dentures can be fitted at a later date.
When dentures no longer fit well, the correct action is to seek follow-up care. Denture adhesive is recommended for dentures, even well fitting ones. Adhesives improve retention, seal the borders to prevent food from slipping under, and cusion the soft tissues from the rigid acrylic. Using denture adhesive may improve the fit, but it tends to work best when only a small amount is used. Covering the entire denture fitting surface in adhesive makes it stay in less well. Adhesives may compensate for gradual loosening of a denture, but it is only a temporary solution; it does not solve the problem. Fortunately, dentures can often be relined with relining materials to improve the fit, and this process costs less than creation of new dentures. Overall, a well-made denture could last about 5 years (or more), but this is different for every patient.
Dentures that fit well during the first few years after creation will not necessarily fit well for the rest of the wearer's lifetime. This is because the bone and mucosa of the mouth are living tissues, which are dynamic over decades. Bone remodeling never stops in living bone. Edentulous jaw ridges tend to resorb progressively over the years, especially the alveolar ridge of the lower jaw. Mucosa reacts to being chronically rubbed by the dentures. Poorly fitting dentures hasten both of those processes compared to the rates with well-fitting dentures. Poor fitting dentures may also lead to the development of conditions such as epulis fissuratum. In addition, the occlusion (chewing surfaces of the teeth) tends to wear away over time, which reduces chewing efficacy and decreases the vertical dimension of occlusion, (the "open-ness" of the jaws and mouth).
The Premium Denture is very high in natural appearance. It features enhanced natural appeal, wear and stain resistance, with detailed customization. As with the UltimateFit and EconomyPlus Dentures, the Premium’s extra-high density teeth are first set in wax for you to try in. Changes may be made at that time. After you have approved the look of your Premium Denture, the lab will custom finish your denture in the permanent acrylic base material. This additional customization results in a more natural look.
