All-on-Four / Pro-Arch
 
Those who have lost all of their teeth — or are soon to have their last, failing teeth removed — have several options for tooth replacement. One of the most advanced and reliable techniques is to permanently attach lifelike prosthetic (new replacement) teeth to dental implants that are anchored in the jawbone, without needing a dental implant for each and every one of your missing teeth.
 
All-on-Four or Pro-Arch treatments have developed over the last decade. Four precisely placed implants are inserted into either jaw and an immediate temporary bridge is secured onto the implants on the same day. This gives the patient the ability to function normally. This means that you do not have to wear a removable denture during the healing phase. Once the bone fuses to the implants (known as osseointegration), impressions are taken and a new bridge is constructed using CAD/CAM.
 
If looked after, the procedure will provide a long lasting restoration to replace your missing teeth.

If you're missing one or more teeth, you may notice a difference in chewing and speaking. There are options to help restore your smile. Bridges help maintain the shape of your face, as well as alleviating the stress in your bite by replacing missing teeth.
If the bone under your gum is not tall enough, not wide enough, too thick or too soft, a procedure can be done to add bone to your jaw before implants can be placed.
When all teeth are missing or in such condition that they need to be replaced, dental implants are the best permanent solution.
