All-on-4 restores an entire dental arch with a fixed prosthesis supported by four implants. It is intended for patients whose jaw is edentulous, or whose remaining teeth can no longer be saved. The two rear implants are placed at an angle, which makes the most of the available bone and often avoids a separate bone graft.
What All-on-4 costs in Tallinn
From the Unidenta price list, per jaw:
- Surgical stage — from €3,000
- PMMA temporary prosthesis — from €1,000
- Fixed zirconia prosthesis — from €4,000
That is from €8,000 per jaw. If you want more support points, All-on-5 (from €9,750) and All-on-6 (from €11,500) are also available.
Who All-on-4 suits
- The upper or lower jaw is edentulous, or the teeth need to be extracted soon.
- A removable full denture will not stay in place, rubs the gums or makes eating difficult.
- Bone volume is reduced at the back but preserved at the front of the jaw.
- You want a solution that does not cover the palate or move when you speak.
How treatment works
- Diagnostics. Examination and 3D imaging, measuring bone volume. Treatment plan with schedule and price.
- Surgery. In a single visit, unsalvageable teeth are removed and four implants placed.
- Temporary prosthesis. Usually fitted within a few days — there is no period without teeth.
- Healing. The implants fuse with the bone over 3–6 months.
- Final prosthesis. The definitive zirconia structure is made and fitted.
All-on-4 or a conventional full denture?
A full denture is cheaper — from €500 at Unidenta — but it rests on the gum, not on bone. Over time a jawbone without load recedes and the denture starts to move. With All-on-4 the implants carry load like tooth roots, which slows bone loss. An in-between option is an implant-supported overdenture: removable, but anchored to implants.
What to expect
- Treatment takes 4–7 months in total, although you have teeth throughout.
- Soft food is advisable for the first weeks.
- Smoking markedly increases the risk of implant failure.
- The prosthesis needs daily cleaning with an interdental brush or water flosser and an annual check-up.
Whether All-on-4 suits you becomes clear from the 3D scan — sometimes bone volume makes All-on-6 the wiser choice. Book a consultation at Unidenta in Tallinn for an individual plan with an exact cost.
