For patients missing most or all of their teeth in an arch, replacing them one implant at a time is not always practical or affordable. The All-on-4 technique was developed to solve exactly this problem.
This article explains how All-on-4 works, the advantages that make it popular, and the questions Markham patients should ask to decide whether it fits their needs.
What is All-on-4?
All-on-4 is a technique that replaces a full arch of teeth using just four dental implants as anchors. Two implants are placed at the front of the jaw and two are angled at the back, which maximizes contact with available bone. A full bridge of teeth is then secured onto these posts.
Because it uses angled placement, All-on-4 often avoids the need for bone grafting, even in patients who have experienced some bone loss.
What are the benefits?
- Fewer implants: A full arch is restored with only four posts, which reduces cost compared with individual implants for every tooth.
- Often no grafting: Angled placement uses existing bone, so many patients avoid additional procedures.
- Fixed, stable teeth: Unlike removable dentures, the bridge stays firmly in place.
- Faster results: A temporary set of teeth can often be fitted sooner than with traditional implant timelines.
Is All-on-4 right for you?
All-on-4 is a strong option for patients who are missing most of their teeth in an arch, who are tired of removable dentures, or who have been told they lack enough bone for conventional implants. A 3D assessment of your jaw is the best way to confirm suitability.

Frequently asked questions
How long do All-on-4 implants last?
With good care, the implants can last many years or decades, while the fixed bridge may need maintenance or replacement over time. Regular checkups and good hygiene are key to longevity.
Is All-on-4 cheaper than individual implants?
Yes. Replacing a full arch on four implants is typically more affordable than placing a separate implant for every missing tooth, while still providing fixed, stable teeth.
Will I have teeth the same day?
Many patients receive a temporary set of fixed teeth shortly after placement, with the final bridge fitted once healing is complete. Your dentist will confirm the timeline for your case.
