How All-on-4 works
Four implants are placed in the jaw. The two in front go in straight. The two in back are usually tilted, which lets them use the stronger bone toward the front of the jaw and avoid the sinuses and nerves. A full bridge of teeth is then fixed to all four. Because the angled implants make the most of existing bone, many patients who were told they needed bone grafts can have this treatment without them.
Who it helps
- People missing most or all of their teeth in one or both jaws
- People whose remaining teeth are badly decayed, loose or failing
- Denture wearers who are tired of slipping, adhesive and sore spots
- People who want fixed teeth without an implant for every missing tooth
The steps
Consultation and 3D scan
A CBCT scan and exam show your bone, nerves and sinuses, and whether All-on-4 or another option fits best.
Planning your teeth and implants
The new teeth are designed first, then the four implants are planned to support them.
Surgery day
Any remaining failing teeth are removed and the implants are placed, with oral sedation if you would like it.
Healing
The implants bond to the bone over the following months. You are not left without teeth during healing.
Final teeth
Your final full-arch bridge is fitted and adjusted to your bite.
All-on-4 or mini implants?
Both can replace a full arch, but they do different jobs. All-on-4 gives you fixed teeth that stay in. Mini implants most often hold a removable denture firmly in place, cost less and can work with thinner bone. Dr. Lemay has placed both for decades and will tell you which suits your mouth and your budget.
