Support is the principle that describes how well the underlying mucosa (oral tissues, including gums) keeps the denture from moving vertically towards the arch in question during chewing, and thus being excessively depressed and moving deeper into the arch. For the mandibular arch, this function is provided primarily by the buccal shelf, a region extending laterally from the back or posterior ridges, and by the pear-shaped pad (the most posterior area of keratinized gingival formed by the scaling down of the retro-molar papilla after the extraction of the last molar tooth). Secondary support for the complete mandibular denture is provided by the alveolar ridge crest. The maxillary arch receives primary support from the horizontal hard palate and the posterior alveolar ridge crest. The larger the denture flanges (that part of the denture that extends into the vestibule), the better the stability (another parameter to assess fit of a complete denture). Long flanges beyond the functional depth of the sulcus are a common error in denture construction, often (but not always) leading to movement in function, and ulcerations (denture sore spots).
Daily cleaning of dentures is recommended. Plaque and tartar can build up on false teeth, just as they do on natural teeth.[24] Cleaning can be done using chemical or mechanical denture cleaners. Dentures should not be worn continuously, but rather left out of the mouth during sleep.[25] This is to give the tissues a chance to recover, and wearing dentures at night is likened to sleeping in shoes. The main risk is development of fungal infection, especially denture-related stomatitis. Dentures should also be removed while smoking, as the heat can damage the denture acrylic and overheated acrylic can burn the soft tissues.
Remember: You can do serious harm to your denture and to your health by trying to adjust or repair your denture. Using a do-it-yourself kit can damage the appliance beyond repair. Glues sold over-the-counter often contain harmful chemicals and should not be used on a denture. If your denture breaks, cracks or chips, or if one of the teeth becomes loose, call your dentist immediately. In many cases, dentists can make necessary adjustments or repairs, often on the same day. Complicated repairs may require that the denture be sent to a special dental laboratory.
Our hope is that, regardless of your skill level when you join one of our lab teams, you will continue to grow as a dental lab professional. ADDL was founded by and is managed by dental lab technicians. What does this mean for you? Not only will you be managed by someone who has experience working in your position, you will have the opportunity to be considered for management team positions, such as on-site management and upper-management roles.
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.
Teeth can fall out for a number of reasons, ranging from genetics to drug abuse. Most commonly, teeth are removed or fall out on their own due to severe tooth decay. Neglect to upkeep oral hygiene or not seeking proper treatment for damaged teeth, can lead to the onset of decay which in turn leads to loss of teeth. Visiting you dentist in 6 month intervals is a good preventive measure to spot any early signs of decay.
