While every effort is made to make a good and functional denture, it is sometimes hard to achieve a stable and retentive denture. This is mainly due to the jaw bone constantly shrinking with age, smoking, or some systemic diseases such as diabetes or even chewing pressure on the existing denture.
However, there are new advances in making dentures. One such advance is an implant-supported denture that increases the stability of the denture. This kind of dental appliance requires the placement of implants in your mouth before making the denture.
Dental implants are used to replace one or more missing teeth in your mouth. Implants are made of titanium or similar materials that are well suited to the human body. They are artificial replacements for teeth roots that support a restoration or a dental appliance.
It normally takes a few phases and several months for your dentist to complete the treatment. In the first phase, your dentist will place the implants in your jaw bone. It requires 3-6 months for the bone to fuse to the implants.
In the 2nd phase, your dentist will place an extension or a post to extend the implants above the gum this process can also be performed during the first phase depending on the technique chosen by your dentist.
After your gums are healed, it is time for an impression to be made and a final restoration or appliance to be fabricated by the dental laboratory. In most cases, on your final visit, the restoration or the dental appliance is placed and adjusted to insure proper fit and function.
While every effort is made to place a successful and functional implant, it is not uncommon for implants to fail. This is mainly due to lack of proper attachment between the implant and the jaw bone during the bone fusing phase.

Finally, due to differences in the shapes of the jaws and the bone density, the back area of upper jaw may require an additional procedure such as "sinus lifting" to increase its predictability and long term success.
