Firm teeth in just one day? Sounds almost too good to be true? The innovative All-on-4 method makes this dream possible. Only four to six implants per jaw are needed to anchor a stable denture. And often without extensive bone augmentation.

In this blog, you will find out how the All-on-4 method works and what advantages it offers over conventional dentures.

Simply explained: What is the All-on-4 concept?

The All-on-4 method (fixed teeth in one day) offers people suffering from tooth loss a quick and reliable solution for fixed teeth. On the very day of treatment, you receive a stable denture that gives you back a better quality of life.

With this special implantation concept, your dentist places only four to six implants per jaw to securely anchor the dentures. The exact number depends on your individual jaw situation.

Your advantages at a glance:

  • Fewer implants, stable hold: your dentist creates a secure base for the fixed prosthesis by placing the implants in a special way.
  • Shorter treatment time: You leave the practice on the same day with your first fixed teeth.
  • Suitable for many: The method is often possible even if the jawbone is small, without the need for extensive additional surgery.

The All-on-4 method is particularly suitable for people who no longer wish to wear loose dentures or who have already lost several teeth.

Are you looking for a stable, fixed denture? Would you like to laugh and eat without a care in the world again? Then this could be the ideal solution for you.

New quality of life in just one day: experiences with the All-on-4 concept

Tooth loss can affect people of any age: whether it is due to tooth decay, periodontitis or accidents. When dentures no longer provide the desired support or teeth are gradually lost, many people look for a permanent solution. An example from our practice shows how the All-on-4 method can make a lasting difference to people’s lives.

  1. After years of ill-fitting dentures, our patient opted for the All-on-4 method. “I was immediately convinced that this was the right decision,” he said after the first consultation.
  2. Dr. Andreas Quidenus inserted six implants in the upper jaw and four in the lower jaw. The operation went smoothly and the patient was able to leave the practice the very next day with temporary, fixed teeth.
  3. After three months, our dental technicians fitted the new teeth perfectly in around four appointments. And soon our patient was able to enjoy everything again without any restrictions.

His conclusion: “After the healing phase, it felt like I had my own teeth back. I could finally eat and smile again without any worries.”

What happens after treatment with the All-4 method?

After treatment, a new chapter in life begins for many people. The feeling of being able to bite firmly again and at the same time being sure that the teeth will not slip brings new self-confidence.

  • Back to old joie de vivre
    Fixed teeth mean more than just functionality: patients often report that they can laugh with confidence again after treatment and enter social situations without feeling insecure. The fear of unpleasant moments – such as a denture slipping out of place – is a thing of the past.
  • Enjoyment without restrictions
    Many people who previously had difficulty eating enjoy everything they like again after All-on-4 treatment. Whether it’s crunchy fruit, a juicy steak or a fresh salad: biting down firmly is no longer a problem.
  • Stability and comfort
    In contrast to removable dentures, teeth fixed on implants are firmly anchored. They feel like natural teeth and offer long-term stability. No slipping, no pressure points: simply more comfort in everyday life.
  • Healthy jaw, healthy smile
    Implants ensure that the jawbone remains stable and does not recede any further. This is often a problem with conventional dentures. This also preserves the facial contours. Your smile looks vital and natural.
  • Fewer visits to the dentist
    With fixed teeth, there is no need for frequent readjustments or relinings, as is the case with conventional dentures. Regular check-ups and good oral hygiene are of course still a must to ensure the longevity of the implants.
