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.
Unlike conventional dentures, immediate dentures are made in advance and can be positioned as soon as the teeth are removed. As a result, the wearer does not have to be without teeth during the healing period. However, bones and gums shrink over time, especially during the healing period following tooth removal. Therefore a disadvantage of immediate dentures compared with conventional dentures is that they require more adjustments to fit properly during the healing process and generally should only be considered a temporary solution until conventional dentures can be made.
It is extremely important to practice healthy dental hygiene when wearing dentures. There is an increased risk of developing a more serious medical condition should oral irritation result from improper dental hygiene. These conditions include, but are not limited to, periodontal disease, leukoplakia (thickened white, potentially precancerous patches on the mucous membranes, also called smoker’s tongue) and fungal (denture stomatitis) infections.
Made from high-quality materials that can mimic the shade and translucency of real teeth enamel, modern dentures offer a much more superior option to their predecessors. Not only that, modern dentures can also be customised to precisely fit your individual mouth and teeth structure. Besides enhancing the natural appearance of your smile, a well-fitted denture will significantly reduce the likelihood of the denture slipping and sliding in your mouth, causing discomfort and potential embarrassment – if they move or fall off in front of others.
Review: My first trip to natural dentures was a visit just short of panic. I had worked with another place before and had my estimate from them, but wasn’t really looking forward to going back. They made me feel just like a paycheck. The people at natural dentures made me feel very comfortable. They were friendly, informative, and welcoming. I was running out of insurance Tim so I had a rather close schedule. And they went out of their way to make it happen. Nels worked very hard at making me happy and doing a outstanding job. I will indeed go back there when I need to and recommend them to anyone that is looking.
By establishing two implanted attachments to the lower jaw, an overdenture is able to sit securely in place to instantly increase retention, stability, and comfort. This is especially important in lower-jaw, full-denture situations where traditional dentures tend to have less adhesion due to a limited foundation and the tongue muscle dislodging the prosthetic teeth.
Partial Dentures: Partial dentures can either be made with a plastic base or a metal framework that supports the number of teeth that need to be replaced. It is held in the mouth by using clasps and rests that are carefully adapted around the natural teeth. The partial denture that uses a metal framework is the traditional design, due to the rigidity and strength of the metal. Plastic partial dentures have normally been used as emergency or temporary replacements of missing teeth, allowing the gums and bone to heal before a definitive restorative solution is obtained. Recently, however, various materials such as Valplast have been developed to provide durable, flexible alternatives in certain situations.
Deposits such as microbial plaque, calculus and food debris can accumulate on the dentures, which may lead to issues such as angular stomatitis, denture stomatitis, undesirable odours and tastes as well as staining. The deposits can also quicken the rate at which some of the denture materials wear down.[26] Due to the presence of these deposits, there is an increased risk of the denture wearer and other people around them developing a systemic disease by organisms such as methicillin-resistant Staphylococcus aureus (MRSA),[27] but research shows that denture cleaners are effective against MRSA.[28][29][30] Therefore, denture cleaning is imperative for the overall health of the denture wearers as well as for the health of people they come into contact with.[31]
Problems with dentures may arise because patients are not used to having something in their mouth that is not food. The brain senses the appliance and interprets it as 'food', sending messages to the salivary glands to produce more saliva and to secrete it at a higher rate. This usually only happens in the first 12 to 24 hours, after which the salivary glands return to their normal output. New dentures can also be the cause of sore spots as they compress the denture-bearing soft tissues (mucosa). A few denture adjustments in the days following insertion of the dentures can take care of this problem. Gagging is another problem encountered by a minority of patients. At times, this may be due to a denture that is too loose, too thick or extended too far posteriorly onto the soft palate. At times, gagging may also be attributed to psychological denial of the denture. Psychological gagging is the most difficult to treat since it is out of the dentist's control. In such cases, an implant-supported palateless denture may have to be constructed. Sometimes there could be a gingivitis infection under the completed dentures, caused by the accumulation of dental plaque. One of the most common problems for wearers of new upper complete denture is a loss of taste sensations.
