What is a dental implant

Dental implants are metal posts inserted into the jawbone 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 (substitute) teeth.

What is the All-on-4® treatment concept

The All-on-4® treatment concept is an effective and efficient technique that uses four dental implants in the upper or lower jaw to secure a set of replacement teeth. These dental implants not only support the substitute teeth, but also act as replacement roots that connect with your jawbone. This allows for a long-term, permanent solution encouraging strong, sturdy support and a natural smile.

The All-on-4® treatment concept was pioneered and trademarked by Nobel Biocare in collaboration with noted European implant dentist Dr Paulo Malo. As a result of our extensive clinical research, the procedure uses the fewest implants possible, avoids the need for bone graft surgery (where substitute bone is added) and delivers a permanent, natural-looking solution in a very short time.

How does the All-on-4® treatment concept differ from dentures

Unlike dentures, the All-on-4® treatment concept will provide you with a permanent, fixed solution that can last a lifetime if cared for correctly. The teeth look and feel natural, and because they are strong and stable you can enjoy all of your favorite foods again – no more worrying about your dentures falling out!

As the replacement teeth are fixed in place they offer all of the benefits of your original teeth, meaning that you don’t have to worry about sagging around your mouth making you look older or annoying adhesives that can make wearing dentures both sore and a chore.

Does the procedure hurt

The All-on-4® treatment concept is designed to minimise pain. In most cases your dentist will offer local anesthetic or a sedative, and after surgery you may experience minimal swelling and soreness. Patients are often surprised at how little pain they feel and how quickly they recover.

How long does it take to recover from the procedure

Your dentist will typically recommend that you take two or three days to adjust to your new smile, however, many people will feel fit to return to their daily schedules as soon as the day after surgery.

How long does it take to complete the All-on-4® treatment concept

After the initial consultation, it normally takes just 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 that removes the need for more complicated surgery. In addition, a couple of follow up appointments are typically necessary to ensure that you’re happy with the results and that everything is healing well.

What is the cost of the All-on-4® treatment concept

The cost of the procedure varies from dentist to dentist but the average cost ranges from £12,000-15,000 per jaw. Since the All-on-4® treatment concept was designed to reduce the need for bone grafting (which can take longer, cost more and be a little painful) and because only four implants are normally used, the cost of the procedure is often 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

Yes! All of the dentists listed on our site are highly trained experts and will work with you to make the replacement teeth that are the ideal shape and shade – they will be virtually indistinguishable from natural healthy teeth. In addition, molds are carefully taken of the natural contours of your jaw to ensure a perfect fit for the shape of your face.

Can any dentist perform the All-on-4® treatment concept

Any dentist surgically qualified to place implants can attempt this type of procedure. However, dentists found using our Find a Dentist search tool on this site have all been certified by Nobel Biocare as “Centers of Excellence” for the All-on-4® treatment concept. This means they have received the proper training and have surgical experience with this technique. Furthermore, all of these dentists will only use high quality products from Nobel Biocare for a beautiful, long-lasting smile.

Does it matter what kind of implants are used for the procedure

Yes. Just like any other medical procedure, the quality of the products used are integral to success. The implants and components used in the All-on-4® treatment concept are permanently in your body so they should be scientifically tested, proven and of the highest quality.

Nobel Biocare is a world market leader in dental implants.

Can I get both upper and lower teeth with the All-on-4® treatment concept


What questions should I ask my dentist to ensure they are the best person to perform the procedure

As a patient, it’s important that you feel comfortable with the procedure so don’t feel shy to ask if you have any concerns. It’s always good to know the qualifications and the experience of the dentists performing the procedure, and also the type of implants that they will be using.

To ensure you feel in safe hands, use our Find a Dentist search tool on this site to locate one of our “Centers of Excellence” near you. These professionals have a proven track record of performing the procedure and use only Nobel Biocare products to ensure the best results. If you have any more concerns or questions you can also contact us for more information.

What is the success rate of the All-on-4® treatment concept

The success of the All-on-4® Treatment Concept has been remarkable. We know this from the positive testimonials of those who’ve had the procedure, and also from the science behind the products. The 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 my age a concern

Not at all! You might feel that your age may prevent you 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 likely to be healthy enough to receive dental implants. If in doubt, you should contact your dentist for a consultation.

I’ve been told I can’t have fixed dentures without bone grafting, is that the case with the All-on-4® treatment concept

The All-on-4® treatment concept 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. 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, if you have any doubts you can check with a dentist at one of our “Centers of Excellence” and they will let you know if you are suitable for the procedure and if it will require bone grafting or not.

Are fixed dentures, the All-on-4® treatment concept, Teeth in a Day and One Smile the same thing

Many names are now being used interchangeably to refer to the All-on-4® treatment concept including, One Day Smile, Teeth in a Day, Fixed Permanent Dentures and more. However, this procedure was first developed and trademarked by Nobel Biocare. 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 Find a Dentist on this website can you be certain that they have been certified as one of Nobel Biocare’s “Centers of Excellence” for the All-on-4® treatment concept. This means that they have received the proper training and have the necessary surgical experience with this technique. Furthermore, all of these dentists will only use high quality products from Nobel Biocare for both your implants and your new set of teeth.

Can the treatment be done with products other than those from Nobel Biocare

The short answer is yes, but this is rarely going to result in the best-case scenario. As Nobel Biocare developed the treatment concept they have also engineered the best dental implants and components for the procedure, all of which are the result of, and are supported by, extensive scientific research and clinical studies. Our implants also come with a lifetime warranty, meaning you can rest assured that you will always receive the best care possible with our products.
