Implant overdentures
Jaw bones tend to resorb and flatten over time. As a result, conventional dentures can be poorly retentive, loose and unstable. This can cause considerable embarrassment while chewing, speaking and during function, thus reducing your quality of life.
Overdentures are a more stable, modern version of traditional dentures. While conventional dentures rest solely on the gum tissue and the underlying jawbone, overdentures are supported by dental implants. Depending on retention needs, the denture can rest on two or more implants per arch.
Overdentures have the same advantage as removable dentures in that they can be removed when required, to be cleaned and reattached to the implants after cleansing. They can be “clicked” onto the implants by means of locators or bars for maximum stability and retention. Locator attachments require replacement every few years.
Patients who are missing most or all of their teeth, have adequate bone levels and an acceptable medical history are usually excellent candidates for implant placement and retention with overdentures.
This is a simple, cost effective and rewarding procedure, which can considerably increase your quality of life.

A comprehensive examination
During the initial examination, radiographs and scans are conducted to assess the volume and quantity of bone available. Using this information, implant numbers and position are determined and a personalised treatment plan is fabricated.
Inserting dental implants
3D planning software is used to finalise the implant positions. Dental implant surgery is a pain-free procedure involving a minor incision in the gums over the jaw bone. The implants are then inserted as planned. A temporary/ immediate denture may be inserted during the healing period.
Healing time
A period of healing is required to allow the jaw bone to fuse with the implant – a process known as osseointegration. This may take several months (3-6) depending upon the site of implant placement, medical condition and bone quality of the individual patient.
Fabricating the overdentures
Following healing and osseointegration, a series of records are taken over 4-5 visits. This involves, primary and secondary impressions, recording jaw relationships, try in and insertion. These records are sent to a trusted laboratory where skilled technicians fabricate the implant overdenture.
Insert and follow-up
Following fabrication, a try-in of fit, shape, shade and appearance of the prosthesis is carried out. The implant overdenture is then inserted onto the locators or bar which are in turn attached to the implants in the jaw/s. Follow up appointments are arranged to ensure that the implant site and prosthesis are closely monitored over the next few months.
