Also known as: All-on-4 dental implants · full-arch implants
All-on-4 replaces all the teeth in one jaw with a fixed set of teeth held by four implants. Two implants go in the front of the jaw and two are angled at the back, which can avoid the need for a bone graft. Most patients need two trips.

How it compares
Both replace all the teeth in one jaw and are held by implants. They differ in whether you can take the teeth out.
Your dentist recommends an option based on your bone, your health and the result you want.
Who it suits
All-on-4 is a full-arch option: it replaces every tooth in one jaw, not a single tooth or a few.
Missing most or all teeth in one jaw
Bone loss at the back of the mouth
You smoke or vape, because it can disrupt healing
Your dentist makes the final decision after examining you and your scans.
Step by step
Treatment happens in two stages: the implants and temporary teeth first, then the final teeth once the implants have healed.
Your dentist examines your mouth and checks your jawbone on X-rays or scans.
Any decayed or damaged teeth are removed first.
Two implants are placed straight in the front of the jaw, and two are angled at the back.
A temporary set of teeth can be fitted the same day.
The implants fuse with your jawbone, which takes about 3 to 6 months. You follow a softer diet while you heal.
Your final set of teeth is made from new impressions and fitted.
The implants themselves can last a lifetime with proper care. How you look after them makes the difference. The risks are the same as for other dental implants.
FAQ
