If you are exploring long-term solutions for tooth loss, you have likely come across the term dental implants. When it comes to replacing an entire arch of teeth, there is more than one option available. One of the most advanced techniques today is the all-on-four dental implant treatment.
At our prestigious Harley Street clinic in London, we have helped hundreds of patients restore their smile, confidence and quality of life through expertly planned implant procedures. In this guide, we explain what all-on-four dental implants really are, how they compare to traditional full-mouth implants, and whether they could be the right option for you.

What Are All-on-Four Dental Implants?
All-on-four dental implants offer a modern and efficient solution for patients who need a complete set of upper or lower teeth replaced. Rather than placing an implant for each missing tooth, this method uses four/six carefully positioned implants to support a full arch of fixed prosthetic teeth.
It is a high-success option that restores function and aesthetics, often with a shorter recovery time compared to other approaches.
All-on-Four vs Full Mouth Implants: The Key Differences
Many patients want to understand how all-on-four dental implants differ from traditional full-mouth dental implants. While both are effective solutions, there are important distinctions between them.
All-on-four uses just four/six implants per arch, whereas a traditional full mouth approach typically involves six to eight implants per arch. This difference impacts the length and complexity of the surgery, the need for additional procedures such as bone grafts, and the overall cost.
From a cost perspective, using fewer implants means all-on-four can be a more cost-effective option without compromising on quality or longevity.
Understanding the Cost of Dental Implants in the UK
We understand that price is one of the most common concerns when considering dental implants, especially when replacing an entire arch. While each patient’s situation is unique, we can offer some general guidance on pricing.
The cost of a single dental implant typically begins from around £3,500. For all-on-four dental implants, pricing starts from approximately £18,000 per arch. Traditional full mouth dental implants, using more implants per arch, usually begin from £30,000 or more.
For those researching dental implant cost, the range of information available online can be overwhelming. That is why we provide clear, transparent treatment plans after a comprehensive clinical assessment.
