Restore your smile in as little as a day
with the original All-on-4® Treatment Concept from Nobel Biocare

Frequently Asked Questions

  • What is the All-on-4® Treatment Concept?
    • All-on-4® Treatment Concept is the name of an effective and efficient technique using 4 dental implants in the upper or lower jaw to secure a set of replacement teeth so they cannot come out. Dental implants support not only a substitute tooth, but create replacement root which connects with your jaw bone. This allows for a long term, permanent solution encouraging strong, sturdy support and a more natural smile. The All-on-4® Treatment Concept was pioneered and trademarked by Nobel Biocare, a world leader in innovative dental solutions, with collaboration by noted European implant dentist Dr Paulo Malo. Our extensive clinical research has resulted in a successful procedure which uses the fewest implants possible, thus avoiding the need for bone graft surgery, and delivers a permanent and natural smile solution in the shortest time possible.

  • How does THE All-on-4® TREATMENT CONCEPT differ from dentures?
    • Unlike denture wearers, those with the All-on-4® Treatment Concept enjoy:

      • A permanent set of teeth that both look and feel natural
      • A permanent set of teeth that won’t fall out at embarrassing moments
      • An uncovered upper palate allowing for more taste when enjoying meals
      • A stable bite force allowing them to eat any types of foods they enjoy
      • Reduced sagging around the mouth which would normally make the face look older
      • No more adhesives, creams or nightly removal
      • No more sore spots or gagging
  • Does the procedure hurt?
    • The All-on-4® Treatment Concept is designed to minimise pain. The dentist offers a local anesthetic or sedative in most cases and afterwards there will be minimal swelling and soreness. Patients are often surprised at how little pain they feel and how quickly they recover. Your dentist may recommend returning to work or their normal routine within 2-3 days, but many patients return to work the very next day.

  • How long does it take to complete All-on-4® TREATMENT CONCEPT ?
    • After the initial consultation, it normally takes just the one day before you are able to say goodbye to your old removable denture and leave the practice with your new, fixed teeth. This is possible due to the strategic positioning of the dental implants which makes potential, complicated surgery unnecessary. In addition, a couple of follow up appointments are typically necessary

  • How long does it take to recover from the procedure?
    • Patients are often surprised at how little pain they feel and how quickly they recover. Two to three days is usually recommended to relax and adjust to your new smile before returning to work, however many patients feel fine and return to work the next day.

  • What is the cost of THE All-on-4® TREATMENT CONCEPT?
    • Though cost varies by dentist, the average cost of an All-on-4® Treatment Concept is approximately £12,000-15,000 per jaw. You may have seen adverts for less, but use caution. Sometimes the lower cost is due to dentists who are not very well qualified or certified to do the procedure and/or they use untested products and implants which are not well scientifically documented. This could be one reason for complications, pain, and failure of the procedure in the long run.


      Since the All-on-4® Treatment Concept was designed to reduce the need for bone grafting, which can take over a year of expensive and painful procedures, and since only 4 implants are normally used the cost can be less than other options. The All-on-4® Treatment Concept is an investment not only in your appearance, confidence, and oral health but also in your overall quality of life.

  • Will the results look natural?

  • Can I get upper and lower teeth with the All-on-4® Treatment Concept

  • What is the success rate of the All-on-4® Treatment Concept?
    • The success of the All-on-4® Treatment Concept has been remarkable, not only based on the positive testimonials of those who’ve had the procedure, but on the scientific proven effectiveness. Published success rates currently stand conservatively at 93.8% and that’s with a 10 year follow-up*. (*Malo P, de Araujo Nobre M, Lopes A, Moss SM, Molina GJ. A longitudinal study of the survival of All-on-4 implants in the mandible with up to 10 years of follow up. J Am Dent Assoc 2011; 142(3); 310-320

  • Is age a concern?
    • Occasionally, older patients express concern that their age may prevent them from enjoying the benefits of dental implants. However, health is more of a determining factor than age. If you’re healthy enough to have a tooth extracted, you’re probably healthy enough to receive dental implants. Please contact your dentist for an analysis and diagnosis related to your particular case.

  • I’ve been told I can’t have fixed dentures without bone grafting, is that that case with the All-on-4® Treatment Concept?
    • The concept of the All-on-4® Treatment is based on angling the dental implants at such a degree as to connect with as much jaw bone as possible. This allows for fewer dental implants, which requires less bone and reduces the need for bone grafting. So for many patients, bone grafting is not necessary because the dental implant and bone can be thoroughly secured with the All-on-4® Treatment Concept. However, please check first with one of the dentists listed on this site.

  • Are fixed dentures, All-on-4® Treatment Concept, Teeth in a Day, One Day Smile the same thing?
    • Many names are now being used interchangeably referring to the All-on-4® Treatment Concept including, One Day Smile, Teeth in a Day, Fixed Permanent Dentures, and more. However, the proven effective technique of permanent dentures on a fixed arch with four implants was developed, and trademarked by Nobel Biocare. But be aware, some dental practice websites claim that they use Nobel Biocare products for the All-on-4® Treatment Concept when in fact they don’t. Only by using the Dentist Finder on this web site can you be certain that they have been certified as one of Nobel Biocare’s “Centres of Excellence” for the All-on-4® Treatment Concept. This means Nobel Biocare UK has verified that each dentist has received the proper training, have the surgical experience with this technique, and have an agreement with them that only high quality products from Nobel Biocare will be used in both the implants used and your new set of teeth.

  • Can this be done with other products other than Nobel Biocare’s?
  • What is a dental implant?
    • Dental implants are metal posts inserted into the jaw bone to replace the roots of missing teeth. They are made of commercially pure titanium—the same material used for replacement joints. Titanium is highly compatible with the human body and fuses with bone, which makes the implant immovable and allows it to act as a solid anchor for prosthetic teeth.
