Removable prosthesis is the one that a patient can remove himself. Removable prosthesis has its pros and cons though it is a preferable choice for many who do not afford expensive treatments like fixed crown and bridge prosthesis and implants or due to unfavourable situations in their mouth.
Those who lose all their teeth either due to serious gum disease or tooth decay, are called, completely edentulous, and the removable prosthesis for them is called complete denture.
Tooth enamel is the hardest part of body but it becomes soft due to dental decay. Dental decay is develops due to the plaque that gets deposited on your tooth surface and shelters the bacteria that penetrate the gums, causing inflammation and pockets. When the damage is severe, the teeth are extracted as a last option. If a few teeth are removed you can opt for a partial denture, if all the teeth are removed, you are a patient for complete denture.
If there are remaining teeth, the option is a partial denture. There are certain specifications for the fixed and removable dentures thereby the treatment modalities are suggested to you as per your dental status. When several teeth in the upper and/or lower sections are missing and you do not have sufficient support available for fixed prosthesis your dentist will suggest you to go for removable partial denture that takes support from remaining natural teeth and the bone.
Types of complete dentures
- Conventional complete dentures
- Immediate dentures
- Tooth supported over-dentures
- Transitional dentures
- Cu – Sil dentures
- Flexy Dentures
Acrylic complete dentures
Different materials used to create dentures include metal, acrylic, and nylon. The artificial teeth that are used are mostly acrylic whereas porcelain teeth can also be used.
Who Should Undergo Conventional complete denture therapy?
Complete dentures are recommended if:
- All set of teeth has been removed
- There are issues with the bite due to missing teeth
- Missing teeth make the patient less confident – This is one of the most common reason why they do not want to have removable dentures. The dentures because they are seating directly on your gums and underneath bone, they do not have any support system other than that. There is nothing in the mouth that can hold the denture in place so that to restrict the movement except when the bone is good in amount and the other factors like salivary secretion that wets the dentures and keeps them in place. The dentures move with the jaw movements if they are not fabricated properly, if the impressions are not recorded precisely or due to any other technical or laboratory errors. Completely edentulous persons are mostly above age 60 and have insufficient bone and thus the loose dentures. They lose their confidence to attend the public gatherings just due to the fear of dentures might come out or might have unnatural movements during talking to people and might create some unnatural situations for them. One can expect immediate results as soon as the dentures are attached. Though they may not look entirely the same as your original teeth, they can help restore certain functions including proper speech and chewing.
What is the procedure?
If you have no teeth left in your mouth and you need complete dentures, your dentist will examine you properly and advice you radiographs such as OPG, full mouth X-ray. If everything is alright your dentist will take impressions of both the upper and lower bony ridges and construct models over which your dentures can be fabricated in the special dental laboratory. Measurement of the space lying between your ridges will be measured (Jaw relation record) so that the length and width of your artificial teeth can be selected for you that matches best to your personality. The dentist will try the waxed-up dentures in your mouth before fixing in permanent material. You can give your suggestons about the teeth how you want them to look for you. After trial the dentures are fabricated using materials such as acrylics. In the next appointment, the dentures are then fitted into the mouth.
The immediate denture is a dental prosthesis that is constructed to replace the lost dentition in upper and lower jaws. It is called immediate because it is insered in the mouth immediately after extraction of teeth. The procedure is bit different than the conventional dentures where the bony ridges are healed an dfirm. Here the extraction wounds heal under the dentures.
It is treatment of choice for those who are in socially exposed job and can not afford being without teeth in their work place. Also they do not have separate time for extraction, wound healing, bone formation and denture fabrication.
If you have few teeth remaining in your mouth and if they are not in good shape, your dentist will advise you to remove them as they are useless.
What is the procedure?
Your dentist will remove all your back teeth first if you have any an dlet the wounds heal atleast for 3 months. After that the impressions will be recorded keeping your front teeth intact in mouth to keep your dental aesthetics maintained and the fabrication will be commensed same as conventional dentures, the only problem is here you can not check how your artificial teeth will look in as the trial will not be possible unless the teeth in your mouth are extracted. The dentures are kept ready when your teeth are extracted an dwithin half an hour they are placed inside the mou. Some adjustments are done so that the dentures fit perfectly in mouth.
Tooth supported overdentures
Tooth supported overdenture is a type of denture for those who have a very few teeth remaining in mouth. The teeth that are healthy and have long roots can serve as abutments that can somewhat help in retention. Main reason behind keeping few teeth in mouth instead of extracting all and giving conventional dentures is, natural teeth stimulate the bone and thus avoid bone loss. There is a structure called periodontium that has periodontal fibres which help in holding the tooth inside the bone. These periodontal fibres send some signals to the bone through their receptors and thus keep the bone intact. That is the reason why your dentist insists on keeping your few healthy teeth intact. The intention is to provide better retaining dentures to you.
What is the procedure?
The teeth that are present in moth need to be treated endodontically (Root canal treatment) first so as to be reduced down 2-3 millimetres above the bone. The teeth are restored using some permanent restorative materials such as post and core, metal copings or amalgam or composite fillings. Sometimes your dentist might use some attachments for more precision (Precision attachments). Denture fabrication procedure is similar to the conventional dentures.
Flexible dentures provide a solution for patients who can’t or don’t want to use regular dentures. The most obvious advantage is that they are stronger and better in retention than conventional dentures. They are flexible and thus move with the muscular movements during chewing and other functions of mouth.
They cling to the gums and don’t require denture adhesive or metal clasps to hold them in place. Other advantages are – the material is clear and allows the natural gum colour to show through. Disadvantages are relining and repairs are difficult and are more expensive than the conventional dentures.
