Implant Supported Dentures

A dental implant is a "root" device, usually made of titanium, used to support restorations that resemble a tooth or group of teeth to replace missing teeth.

The dental implants are root-form endosseous implants, i.e., they appear similar to an actual tooth root and are placed within the bone. The bone of the jaw accepts and osseointegrates with the titanium post. Osseointegration refers to the fusion of the implant surface with the surrounding bone. Dental implants will fuse with bone and thereafter when the implant is properly integrated in the bone then it can be finally loaded with the dental prosthesis. Dental implants can be used to support a number of dental prostheses, including crowns, implant-supported bridges or dentures.

 

 

IMPLANT SUPPORTED DENTURES

With ageing process the degenerative changes can also be seen in the mouth. Sometimes due to negligence, caries or some other reason the person may lose all its teeth. Loss of teeth produces number of changes in the persons habits which may include difficulty in eating, speaking and may also produce some type of psychological depression and person usually try to avoid socialising himself.

In earlier day’s removable complete denture were the only available options for the patient but with the introduction of implants there are numbers of option available with dentures.

Patients who wear removable complete dentures and have problem of loose dentures may go for implant retained denture wherein two implants in the lower jaw and two in the upper jaw can be placed and these implants provide retention to the dentures. These dentures need to be removed in night like other denture.

The other one is implant supported overdentures wherein the implants are placed in upper and lower jaws followed by placement of complete dentures. These dentures are retained in place by means of a bar framework which is attached to the dental implants over which denture gets attached. These dentures can be removed by the patients and can be cleaned.
 


The new technique of ALL ON FOUR is also a method to rehabilitate patients with complete loss of teeth. In this 4 implants are placed in upper jaw and 4 implants are placed in lower jaw and the denture is secured by means of screws which hold the denture with the implants. These dentures need not be removed by the patients and can be periodically removed by dentist and cleaned.

Most important benefit with implant supported prosthesis is that it decreases the bone resorption rate and increase the life of denture and patient also feel more convenient with it.
