False Teeth and Dentures

Dentures are false teeth normally replaced when somebody missing them partially or fully. These teeth are normally supported by the soft as well as hard material around it, which is normally designed to give support and to keep the teeth placed in the oral cavity. These teeth are both fixed and removable depending on the location these are placed. There are two arches of the mouth I-e upper and lower jaw. Upper jaw is called maxilla and the lower one is named as mandible and similarly the dental prosthetics are named.

History of Dentures

Traces of denture’s emergence have been found since 15th century but there are strong possibilities of its existence well before that time. People of ancient times use bones, ivory or teeth snatched from the bodies of the dead people in war. That time, dentistry was also in its infancy so these implants were not of very good quality and wore in very short period of time. People, who were well off at that time, also use prosthetic teeth but material was very expensive I-e gold and silver. Porcelain dentures were, firstly, made in the last third decade of eighteenth century by Alexis Duchateau.

Dentures are normally indicated in many situations such as teeth loss (any reason I-e aging, trauma, fight, falling or any road traffic accident), any disease related to the gums and teeth, genetic or any other reason of tooth decay or impaired dental developments and many more. Dentures are used for physiological reasons, aesthetic causes, phonetics and self esteem improvements. This prosthetic device gives lot of support to the oral cavity and helps in mastication to improve the saliva production and ultimately digestion. Moreover, aesthetic improvements by the use of dentures are remarkable.

Types of Dentures

Dentures are classified on the basis of their placement such as complete and partial dentures. Complete dentures are used mostly in those individuals in whom there’s not much left in the mouth and one of the arches is completely toothless and the placement of complete denture is recommended. Partial dentures are used in those individuals who are missing only few teeth. Partial dentures are more practiced in dentistry clinics because accidental damages affect only few teeth and incidence of accidental traumas are far greater than other reasons. Partial denture placement is a dental specialty because dentist have to look after all the aspects such as angles of placement for normal mastication; acceptable facial appearance while the moth is open and close; approximation with the opposite arcade so it definitely helps in mastication and wouldn’t bother the individual; presence of any periodontal diseases close to the prosthetic placement and many more.

There are many impediments and difficulties in the placement of these prosthetic devices because individuals are not normally used to having anything in their mouth which isn’t food. Problem with the prosthetic device is that sensations present in the oral cavity send messages to the brain and consider that stuff as food and result in massive salivation. Moreover, if the prosthetic is not placed properly and it is loose fit then sores can develop in the oral cavity that might lead to oral ulcers and many other serious complications. Dentures which are loosely fit always originate complains regarding gagging. Sometimes, dentures are placed too far in the oral cavity that it has direct contact to the soft palate and this might also be one of the causes of continuous gagging. Additionally, highly sensitive individuals may also signs of gagging and reason behind most of the time is psychological unacceptability of the dentures. These cases are then treated with palateless dentures which are supported by the implants. At times, patient may also experience loss of taste to some extent.

Those individuals who have very weak teeth and always planning to visit their dentists, dentures are a nice option for them. Complete removal of all teeth and placement of dentures in upper and lower arcade is a possibility for such individuals. But, most of the people have sen regretting after the dentures have been placed because the dentures can deliver only 15-20 % of the total masticatory force as compared to the natural teeth and patients have to work more to chew their food.

Fitting Dentures

For appropriate denture fittings, there are three main principles that should be at the top in the priority list of a dentist. Firstly, support; the oral cavity offers to this foreign material in the oral cavity. Maxillary portion of the denture is normally supported by an extended palate while mandibular dentures are supported by buccal shelf and gingival mucosa. Healthy mucosa can produce remarkable results. Secondly, stability; lateral, upward, downward or any movement should be restricted because a slightly loose fit can originate these movements and it ultimately results in failure of the dentures. Appropriate approximation of the edentulous ridges and denture base can ensure good stability. Thirdly, retention; excellent chemistry between the surface of the dental mucosa and denture base can result in excellent retention of the denture.
