Overdentures are very stable but removable replacement teeth retained by dental implants that help both partial and fully edentulous patients regain a far better quality of life. The replacement teeth are retained by implants placed in the upper and/or lower jaw and the overdenture is secured to the implants through special attachments incorporated into the denture.
Key features of overdentures:
- A far more cost-effective way of replacing missing or failing teeth
- Provide significantly improved retention when compared to conventional dentures
- No need for a palate in the upper denture which improves both taste and temperature perception
- Being removable allows for easy cleaning of both the denture and implant abutment
- Easily maintained and repaired
Implant-supported crowns and bridges
The replacement of a single tooth with an implant-supported crown has many advantages over other treatment options and is used to restore the shape, function and appearance of natural teeth. When more than one tooth is missing implant-supported bridges can be used as an alternative to multiple implant-supported crowns and to span gaps where teeth have been lost.
Key features of implant-supported crowns and bridges:
- No need to wear a removable partial denture as a long-term solution to missing teeth
- No need to cut down healthy natural teeth to support a conventional bridge
- Aids bone preservation
- They are a long-lasting solution to improving your appearance and bite
For dental implants to be successful there needs to be enough jawbone to support them. If it is found there is not enough bone you will first need a procedure to add bone to your jaw before implants can be placed.
A bone graft is the addition of bone, or special bone-like material, to increase the volume of bone in the jaw and is placed and allowed to heal before any implants can be placed. There are many different types of bone grafts and the type given will depend on the individual case and amount of bone required. In some cases bone grafts may be placed at the same time as the implant.
If teeth have been missing in the upper jaw for any length of time the bone and surrounding tissues start to disappear. A sinus lift, or sinus augmentation, is surgery that adds bone to your upper jaw in the area of your molars and premolars when there is not enough bone, or the sinuses are too close to the jaw for implants to be placed.
