Your journey to a new smile

Four carefully planned steps

From your first assessment to your new smile and long-term care.
1

Full Clinical Assessment

Allow up to 2 hours
Free of charge*

Your full clinical assessment, 3D scans and personalised treatment plan, all planned in a fully digital workflow to ensure accuracy.

* One free consultation per person.

2

Your Surgical Reset

Usually 4 to 6 weeks after assessment

Your planned procedure: implants and new fixed teeth, usually in one appointment. Your surgery is fully guided, for precision and speed.

You leave the chair with fixed teeth. No waiting around on the day. This is the 21D way.

You are not put to sleep. Oral medication helps you relax and a local anaesthetic numbs the treatment area.

3

Healing, checking and refining

Usually 4 to 8 weeks after surgery

The timing is a clinical decision, not patient choice. We check your healing and implant stability, and capture new digital scans.

4

Your final smile sign-off

Allow approximately 60 minutes

This appointment may or may not involve adjusting and refining your prosthetics. That’s a clinical decision. We’ll also explain how to look after your new smile.

Annual maintenance

Your smile is a long-term investment. Annual maintenance helps us monitor your implants, bone and prosthetics. Attending every year keeps your warranty valid.

The annual maintenance cost is currently £250 per annum (October 2026), payable prior to the appointment.

Rebuilding lost smiles.
‍It's all we do.

We focus entirely on the people with very high need: people who need all their teeth replacing with implants.

Built so it lasts and is easy to look after

A fully digital workflow

We use a fully digital workflow to ensure accuracy.

Fully guided surgery

All our surgery is delivered fully guided, for precision and speed without compromise.

Fixed teeth in around three hours

Surgery usually takes three hours for both jaws. Not the whole day. You leave the chair with fixed teeth.

Patent pending modular prosthetic

Our screw-assembled prosthetic makes long-term management simple: easy to replace if needed, and affordable. No cement, and the veneer is replaced in minutes, without drills or needles.
