The procedure of downsizing and covering the teeth that have suffered excessive material loss due to decay, fracture or other similar reasons and cannot be restored with composite/porcelain fillings. Upon the request of the patient, crowns containing metals (alloys of precious or non-precious metals) or metal-free crowns (zirconium) that suit the type of used porcelain the most may be applied.
The type of fixed prosthesis used for filling the gaps caused by the absence of one or more teeth by downsizing the supporting teeth. Applied in the event when the implants cannot be fixed or are preferred. Just like a crown application, the choice of the base and the type of used porcelain depends on the size of the gap and the patient’s wish.
How are crowns and bridges made?
Before either a crown or a bridge can be made, the tooth (or teeth) must be reduced in size so that the crown or bridge will fit over it properly. After reducing the tooth/teeth, your dentist will take an impression to provide an exact mold for the crown or bridge. If porcelain is to be used, your dentist will determine the correct shade for the crown or bridge to match the color of your existing teeth.
Using this impression, a dental lab then makes your crown or bridge, in the material your dentist specifies. A temporary crown or bridge will be put in place to cover the prepared tooth while the permanent crown or bridge is being made. When the permanent crown or bridge is ready, the temporary crown or bridge is removed, and the new crown or bridge is cemented over your prepared tooth or teeth.
How long do crowns and bridges last?
Crowns and bridges can be used for many years. The most important step you can take to ensure the longevity of your crown or bridge is to practice good oral hygiene. Keep your gums and teeth healthy by brushing with fluoride toothpaste twice a day and flossing daily. Also see your dentist regularly for checkups and professional cleanings.
REMOVABLE PROSTHESIS (TOTAL AND PARTIAL PROSTHESIS)
Full and partial prosthesis are the apparatus designed to complete missing teeth, recover lost functions (chewing), phonetic problems (speech) and aesthetics and, to maintain and sustain health of the tissues and teeth remaining in the mouth. As the prosthesis are removable and can be taken out and replaced by the patient, the assiduity shown and the cleaning and care to be performed by the patient are crucial in terms of prosthesis and health of the patient. Besides the recovery of the missing teeth, using prosthesis is effective in terms of the general health of the patient since the teeth are the first link of the digestion system.
1) Total prosthesis (complete palate): Type of prosthesis applied for patients who have lost all teeth.
In recent years, total prosthesis lost their attribute of being the only alternative for completely toothless mouths. Implants placed into the jawbone and prosthesis prepared by obtaining support from these, give to patients the feeling of chewing with their own teeth and for this reason are frequently preferred as an alternative to total prosthesis.
2) Partial (sectional) prosthesis: Type of prosthesis that are attached to the tooth with metal pieces called crochets (hooks) that are made of the combination of special acrylic and metals.
3) Precision attachment prostheses (prosthesis with locking pins): Another type of prosthesis used in partial loss of teeth. Compared to classic partial prosthesis, this type of prostheses is more aesthetic, as they do not contain crochets (hooks), frames and other metal bases.
4) Removable implant supported prosthesis: Prosthesis similar to total prosthesis, which are installed on the implants, that are fixed to patients with insufficient bone stock (support). The shape and degree of stability of the prosthesis varies depending on the number of used implants.
Maintenance and cleaning of removable total and partial prostheses:
The procedure to be followed by a patient using total or partial prosthesis are as follows:
Clean the inner and outer surfaces of your prosthesis by removing it and using a toothbrush and soap after every meal. The conducted researches have proven that the method of cleaning the prosthesis by rubbing it with fingers under running water is not beneficial but just spreads the microorganisms that are present on the prosthesis and hands to the entire surface of the prosthesis. Clean the inner and outer surfaces with a toothbrush and soap without fail.
If you are having difficulties with holding the slippery prosthesis while cleaning and are worried about dropping it, perform this procedure by placing the prosthesis on a soft cloth. This small procedure will prevent the prosthesis from being dropped and broken.
Tooth paste can lead to the loss of smoothness of the surface of your prosthesis. Deteriorationof smoothness of the surface can create favorable conditions for adhesion (attachment) of microorganisms, thus hindering the process ofcleaning.In such a case, see your dentist and ask him/her remedy the problem. Do not use any kinds of cleaning agents that are produced for different purposes, such as bleacher, detergents etc. for cleaning the prosthesis. These agents not only damage the structure of the prosthesis, but are also extremely dangerous in terms of general health.
You may carefully use the tablets and solutions, produced especially for cleaning the prosthesis, in accordance with the instructions of the manufacturing company.
The hygiene of the inner mouth tissues, on which the prosthesis is placed, is also very crucial. If you place your prosthesis after cleaning it into an unclean mouth, the cleaning you have done will be wasted. Clean the toothless area in your mouth with a soft toothbrush or gauze after taking out your prosthesis and cleaning it. If there are some teeth in your mouth, also clean them with a toothbrush and tooth paste without fail.
Cleaning the crochets that ensure attachment of the partial prosthesis to the remaining natural teeth is extremely important in terms of protection of the remaining teeth in the mouth. If the food residues around and on inner surfaces of the crochets are not removed properly, they will damage the teeth. The crochets must be cleaned after each meal without fail.
When you remove your prosthesis keep them in a cup filled with water.
Do not perform or let others perform any operation on your prosthesis, such as grinding or additional repairs out of the control of your dentist. If you have a problem with your prosthesis, see to your dentist immediately.
Visit your dentist regularly once every 6 months for check-ups. These check-ups will prevent the problems which might arise in the future.
Remember that your prosthesis has a limited lifespan and must be replaced every two to five years. Otherwise, the adoption of the prosthesis on the newly formed tissues will be deteriorated and, its usage will become more difficult.
