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.
If needed, patients can get a full set of upper or lower dentures, but many patients get partial removable dentures and keep as many of their natural teeth as possible. Partial dentures can replace one or more teeth in the upper or lower set, allowing spaces for natural teeth. In other words, the teeth in partial dentures do not need to be next to each other.
Dentures provide several cosmetic benefits. They fill in gaps left by missing teeth so a person can feel more confident about his or her appearance. Dentures also prevent further shifting of the remaining teeth and improve facial structure. They offer a range of functional benefits, which include helping the patients chew food more easily and improving speech.
Fixed bridges are another tooth replacement option that are typically more durable and a more permanent solution than denture arches. A bridge spans the length of at least three teeth to replace a missing tooth or teeth in between. Bridges are cheaper than dental implants but do not offer all the same benefits when compared to replacing a missing tooth with an implant.
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.
