All on 4

An advanced, cost-effective procedure that can transform your smile and allow you to eat foods you never thought you’d eat again. The Sydney Implant Institute can deliver you a new set of teeth in as little as a day.

What is an All on 4 (AO4)?

All on 4 dental implants are an innovative and increasingly popular procedure whereby an entire set of broken down, loose, painful or missing teeth are replaced with a new set of fixed teeth. The new teeth are supported by just four dental implants, which are inserted into the jaw bone.


A cost-efficient and permanent solution that provides a fixed, full-arch prosthesis. Implants are fixed and do not need to be removed


Surgery is usually completed in one day and the teeth are issued that evening or the following day


Fewer surgical appointments means faster recovery time and less trips to the dentist!


Recommended by 98% of patients who see a rapid improvement in function, aesthetics, speech and self-esteem*

How does All on 4 work?

An All on 4 replaces an entire arch of teeth (upper or lower) with four dental implants and a fixed bridge. If you need the upper and lower teeth replaced, there will be eight dental implants and two bridges. Before All on 4, we used six to ten implants per arch of teeth and usually with a large amount of bone and gum grafting.

All on 4 utilizes the bedrock bone in front of the sinuses in the upper jaw and in front of the dental nerves in the lower jaw. Bone grows into the implants allowing them to be fixed and able to support teeth. The back implants are angled which means we use the good bone in the front part of the jaws. This angulation also allows the top of the implant to be in line with the position of a first molar, meaning we can replace 12 teeth (first molar to first molar) with just 4 implants and no bone grafting.

Dental AO4 Bridges (Initial and Upgrades)

Play Video

Your All on 4 bridge can be made from a number of different materials. Everyone undergoing an All on 4 at The Sydney Implant Institute will initially be issued a metal reinforced acrylic bridge. We utilise Sydney’s most specialised and premium dental laboratory to fabricate our bridges. Located just up the road in Macquarie street Assia and his team (see video) use Phonares premium teeth and high impact Ivocap acrylic to create a beautiful and durable bridge. This bridge is included in the initial All on 4 cost.

Acrylic and Titanium

Also known as a “hybrid” bridge, this bridge utilises a custom milled titanium substructure to support the same material and teeth the initial bridge was fabricated from. The main difference between this bridge and the original bridge is that the strength is obtained from the titanium substructure, not the bulkiness of the acrylic.

  • You must fast (no food or drink except a few sips of water) from midnight the night before surgery
  • Do not drive yourself to or from the surgery and please be accompanied by someone. They will likely want to go for a walk or leave the surgery while you are in surgery and recovering. They can go home and come back before the bridge is issued if that is more convenient.
  • If you have any questions, write them down so you can ask the team before surgery.
  • Discuss your medications with your dentist, GP or sedationist prior to taking them before the procedure .
  • Wear comfortable, loose fitting and warm clothing.
  • Bring an Ipad or something to read if you’d like and a secure bag for your belongings
