"Is 4 or 6 implants better?" is the most frequent question of those who evaluate one Toronto Bridge. In this guide we answer with clear clinical criteria and real numbers: how much does a Toronto Bridge cost on 6 systems, in which cases the two additional systems are really useful and when 4 systems are sufficient.
Why 6 systems instead of 4
The Toronto Bridge on 4 lifts (protocol All on 4) uses inclined posterior implants to bypass areas with little bone. The version on 6 plants it distributes the load over multiple support points: each implant works less, the prosthesis is more stable and there is redundancy — if one implant has problems over the years, the prosthesis remains supported by the other five.
Six implants are particularly suitable when: the bone is of good quality and volume (there is room to position them all at a good angle), the patient has a very strong chewing or bruxism, that is the arch to be rehabilitated superior with medium-good quality bone, or you want the maximum possible durability of the product.
How much does it cost: price comparison
| Configuration | Average price in Italy | From Sanitadental Clinic |
|---|---|---|
| Toronto Bridge on 4 systems (arch) | €8.000 – €13.000 | from €2,800 to €4,000 arched, depending on the case |
| Toronto Bridge on 6 systems (arch) | €10.000 – €15.000 | from €3,400 to €4,500 arched, depending on the case |
| Fixed temporary prosthesis | sometimes quoted separately | included in the plan |
| Future relining of the resin prosthesis | €500 – €1.500 | listed in writing in the maintenance plan |

The difference between 4 and 6 implants with us is a few hundred euros per additional implant (components + surgery): the price never doubles. The exact estimate — 4 or 6 implants, with possible extractions or grafts — is defined only on an x-ray or CT scan: request it for free via contacts.
4 or 6 systems: how you decide
The decision is clinical, not commercial, and is based on three elements evaluated with the 3D CT scan: bone volume and density available in strategic areas, length of the prosthesis (the more the prosthesis extends towards the bottom of the arch, the more posterior support is needed), e masticatory forces of the patient.
With poor bone in the posterior areas, 4 inclined implants are often the best choice because they avoid grafts. With good bone, 6 implants give a higher margin of safety. Those who always and only propose 6 implants - or always and only 4 - probably start from the price list and not from the CT scan.
Procedure and times
The operation with 6 implants lasts approximately 2-3 hours per arch under local anesthesia (sedation available on request). The protocol is the same as the 4 implant version: extractions if necessary, insertion of the implants, fixed temporary within 24-72 hours when primary stability allows it, definitive after 3-6 months of osseointegration.
For patients arriving from Italy we organize the plan in two trips in most cases, with assistance in Italian throughout the entire journey. You can find the complete description on the page Toronto Bridge treatment.
Because our price is lower than the Italian average
Two more implants mean more components and more surgical work: in Italy this often translates into +€2,000/3,000 of estimate. Here the increase remains limited because i operating costs of the clinic and internal laboratory are lower, not because we save on materials: we use implants from international CE-certified manufacturers and the same surgical-prosthetic protocol as the best European practices. Italian colleagues charge higher prices for structure and laboratory costs, not for a difference in intrinsic quality.
