| I have been making Dentures for 30 years and it still amazes me why someone hasn't came with a softer more flexible Denture. Hard plastic Dentures cause Denture Wearers alot of Gum Structure Problems. Dentures are made of Hard Plastic Dental Resin actually to hard for human jaws and gum structures, causing sore irritating gums especially when they become loose and sounding like marbles clacking around in your mouth. They are testing new flexible materials but there having a problem keeping denture teeth from falling out. But someday soon they will perfect softner more flexible Dentures for the Denture Wearers to be confortable with. Dentures being softner and more flexible should feel alot more like there own natural teeth. |

| Getting use to New Dentures for the First Time Denture Wearer! |
| Getting use to New Dentures can have it's problems like no room in your mouth for food, slurred speech, feels like two rocks in your mouth, hard time chewing, bitting your tongue etc.. All this is natural and your worst enemy is YOUSELF and your best friend is TIME! So take your time if this is your first time wearing Dentures as time goes by they will keep feeling better and better. Even after only having your them a for a few hours they will start feeling more natural to you so let time help you get use to them. Upper Dentures (top ones) are easier to get used to then the lowers. With upper Dentures you have a (palate) roof of your mouth for suction to help hold them in. It will form a seal around the rim of your Dentures and hold them in tighter than the lower Dentures. Lower Dentures just set on the ridge of your lower jaw bone with really nothing to hold them down tight. Wearing lower Dentures can be much more difficult than wearing upper Dentures. |
| Problems Dentures can Cause |
| Dentures cause Slurred Speech--- not use to them or Dentures could be to thick Dentures Clacking against each other--- not use to them yet or to Loose Dentures become Loose and Irritating--- Dentures are to Loose and need relined Dentures will cause Sore Spots--- Dentures are to long in certain areas Dentures can gag you--- Dentures to long in roof of mouth Dentures can cause Gum Shrinkage--- caused by weight loss and hard Dentures |
| Helpful Hints for New Dentures |
| 1. Take Small Bites 2. Take your Time 3. Just play aroung with your Dentures the first few days. 4. Getting use to Speaking more clearly---Read out loud and listen to the words that come out wrong and then say them over and over until you say them right. 5. Put alittle water in sink before cleaning your Dentures, if you drop them they will just hit the water and won't break 6. Sleep with your new Dentures in your mouth the first few nights, it will help you get use to them faster. |
| Dentures (also known as dental plates), can be defined as a set of artificial teeth, which are used when a patient has lost real teeth on the mandibular arch, the maxillary arch, or both. Patients can become entirely edentulous (without teeth) due to severe malnutrition, genetic defects such as Dentinogenesis imperfecta, periodontal disease, tooth decay or trauma. Dentures can help give the edentulous patient better masticatory (chewing) abilities, as well as enhance their aesthetic appeal by providing the illusion of having natural teeth, providing support for their lips and cheeks, and correcting the collapsed appearance commonly seen between the nose and the chin.
Removable partial dentures are for patients who are missing some of their teeth on a particular arch. Fixed partial dentures, better known as permanent bridges, are made from crowns that are fitted on the remaining teeth to act as abutments and pontics made from materials to resemble the missing teeth. Fixed bridges are more expensive than removable appliances but are more stable. One type of fixed bridge, a cantilever bridge uses only a tooth or teeth to support the entire bridge and should be used only when the span is not more than the supporting teeth. Conversely, complete dentures or full dentures are worn in patients who are missing all their teeth in an arch (i.e the maxillary or mandibular arch).

They were carved from bone or ivory, or made up of teeth sourced from graveyards, the recent dead or living donors who exchanged their teeth for profit. These dentures were uncomfortable, attached visibly to a base supported by any remaining teeth with a thread of metal or silk. The false teeth were often made with ivory from the hippopotamus or walrus, and usually rotted after extended use. [citation needed]London's Peter de la Roche is believed to be one of the first 'Operators for the Teeth', men who fashioned themselves as specialists in dental work. Often these men were professional goldsmiths, ivory turners or students of barber-surgeons.[1] The first porcelain dentures were made around 1770 by Alexis Duchâteau. In 1791 the first British patent was granted to Nicholas Dubois De Chemant, previously assistant to Duchateau, for De Chemant's Specification, "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." He began selling his wares in 1792 with most of his porcelain paste supplied by Wedgwood.[citation needed] Single teeth in porcelain were made since 1808. Later dentures were made of vulcanite and then, in the 20th century, acrylic resin and other plastics. In Britain in 1968 79% of those aged 65-74 had no natural teeth, by 1998 this proportion had fallen to 36%.[citation needed] [edit] Problems with Complete Dentures This article or section does not adequately cite its references or sources.

Problems with dentures include the fact that patients are not used to having something in their mouth that is not food. The brain senses this appliance as "food" and sends messages to the salivary glands to produce more saliva and to secrete it at a higher rate. New dentures will also be the inevitable cause of sore spots as they rub and press on the mucosa. A few denture adjustments for the weeks following insertion of the dentures can take care of this issue. Gagging is another problem encountered by some patients. At times, this may be due to a denture that is too loose fitting, too thick or not extended far enough 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 or a hypnotist may need to be consulted). Sometimes there could be a gingivitis under the full dentures, which is caused by accumulation of dental plaque. Another problem with dentures is keeping them in place. There are three rules governing the existence of removable oral appliances: support, stability and retention. [edit] Support Support is the principle that describes how well the underlying mucosa (oral tissues, including gums and the vestibules} keeps the denture from moving in the vertical plane towards the arch in question, and thus being excessively depressed and moving deeper into the arch. For the mandibular arch, this function is provided by the gingiva (gums) and the buccal vestibule (valley region between the gums and the lip), whereas in the maxillary arch, the palate joins in to help support the denture. The larger the denture flanges (part of the denture that extends into the vestibule), the better the support. More recently, there has been a move to increase denture stability with implants. When pressure is applied to alveolar bone bereft of teeth (alveolar bone is the bone in which teeth normally reside), the bone reacts to this pressure by resorbing. After many years of denture wearing, the ridges upon which the dentures rest deteriorate and can easily all but disappear. The insertion of implants into the bone below the dentures can help to seriously combat this unfortunate occurrence. The implants are strategically placed to bear the brunt of the pressure when the denture is used for chewing, keeping the bone from melting away. When implants are integrated into treatment, the denture is now referred to as being an implant supported overdenture and the implants are referred to as overdenture abutments. [edit] Stability Stability is the principle that describes how well the denture base is prevented from moving in the horizontal plane, and thus from sliding side to side or front and back. The more the denture base (pink material) runs in smooth and continuous contact with the edentulous ridge (the hill upon which the teeth used to reside, but now consists of only residual alveolar bone with overlying mucosa), the better the stability. Of course, the higher and broader the ridge, the better the stability will be, but this is usually just a result of patient anatomy, barring surgical intervention (bone grafts, etc.). [edit] Retention Retention is the principle that describes how well the denture is prevented from moving in the vertical plane in the opposite direction of insertion. The better the topographical mimicry of the intaglio (interior) surface of the denture base to the surface of the underlying mucosa, the better the retention will be (in removable partial dentures, the clasps are a major provider of retention), as surface tension, suction and just plain old friction will aid in keeping the denture base from breaking intimate contact with the mucosal surface. It is important to note that the most critical element in the retentive design of a full maxillary denture is a complete and total border seal in order to achieve 'suction'. The border seal is composed of the edges of the anterior and lateral aspects AND the posterior palatal seal. The posterior palatal seal design is accomplished by covering the entire hard palate and extending beyond and ending onto the soft palate. As mentioned above, implant technology can vastly improve the patient's denture-wearing experience by increasing stability and saving his or her bone from wearing away. Implant can also help with the retention factor. Instead of merely placing the implants to serve as blocking mechanism against the denture pushing on the alveolar bone, small retentive appliances can be attached to the implants that can then snap into a modified denture base to allow for tremendously increased retention. Options available include a metal Hader bar or precision balls attachments, among other things. [edit] Complications and Recommendations The fabrication of a set of complete dentures is a challenge for any dentist, including those who are experienced. There are many axioms in the production of dentures that must be understood, of which ignorance of one axiom can lead to failure of the denture case. In the vast majority of cases, complete dentures should be comfortable soon after insertion, although almost always at least two adjustment visits will be necessary to remove sore spots. One of the most critical aspects of dentures is that the impression of the denture must be perfectly made and used with perfect technique to make a model of the patient's edentulous (toothless) gums. The dentist must use a process called border molding to ensure that the denture flanges are properly extended. An endless array of never-ending problems with denture may occur if the final impression of the denture is not made properly. It takes considerable patience and experience for a dentist to know how to make a denture, and for this reason it may be in the patient's best interest to seek a specialist, either a Denturist or a Prosthodontist, to make the denture. A general dentist may do a good job, but only if he or she is meticulous and usually he or she must be experienced. The maxillary denture (the top denture) is usually relatively straightforward to manufacture so that it is stable without slippage. The lower full denture tends to be the most difficult because there is no "suction" holding it in place. For this reason, dentists in the late 1990s have come to a general conclusion that a lower full denture should or must be supported by 2-4 implants placed in the lower jaw for support. A lower denture supported by 2-4 implants is a far superior product than a lower denture without implants, held in place with weak lower mouth muscles. It is routine to be able to bite into an apple or corn-on-the-cob with a lower denture anchored by implants. Without implants, it is quite difficult or even impossible to do so. Some patients who believe they have "bad teeth" may think it is in their best interests to have all their teeth extracted and full dentures placed. However, statistics show that the majority of patients who actually receive this treatment wind up regretting they did so. This is because full dentures have only 10% of the chewing power of natural teeth, and it is difficult to get them fitted satisfactorily, particularly in the mandibular arch. Even if a patient retains one tooth, that will contribute to the denture's stability. However, retention of just one or two teeth in the upper jaw does not contribute much to the overall stability of a denture, since a full upper denture tends to be very stable, in contrast to a full lower denture. It is thus advised that patients keep their natural teeth as long as possible, especially their lower teeth. [edit] Conclusion As can be expected with any removable appliance placed in the mouth, there will be some problems (in respect to the three principles mentioned above) with dentures no matter how well they are made. This is because the best the dentist can do is fabricate the upper denture to work in harmony with the lower denture when the patient is at rest. If the only variables in the equation are the patient's edentulous ridges and the two dentures, the dentist can set the teeth in certain ways to help prevent dislodgement during opening, closing and swallowing. Once food enters into the picture, though, the stability of the denture bases is not impervious to disruption. During chewing, the denture bases will sometimes act as class 1 levers, and when the patient bites down on the anterior, or front, teeth, the posterior, or rear, teeth are bound to move away from the ridge. Although the ideals of denture design will have it that the intaglio surface is in perfect, intimate contact with the ridge and the margins of the denture base will create a perfect suction seal (the seal is actually only on the maxillary denture), ideals are rarely if ever met in this imperfect world, and thus some movement is to be expected. Denture adhesive can then be utilized to compete against the forces trying to pull the denture base away from the mucosa. In a perfect world, a patient with a perfect edentulous ridge with a perfectly fitting denture would require no adhesive, as the actual form of the denture base should work in tandem with the three principles mentioned above, thus precluding movement in any way, shape or form. |
