For many people, tooth loss is a major turning point, affecting not only the aesthetics of their smile, but also everyday life – speaking, chewing and self-confidence. Fortunately, today there are several ways to replace teeth. For a long time, the most common solution was a removable complete denture. In recent years, however, more and more patients have chosen a modern alternative – fixed teeth on implants, most often using the All-on-4, All-on-6 or All-on-x method. Why is this option considered a breakthrough in tooth replacement?


What does All-on-4/6/x mean?

The All-on-4 method involves strategically placing four dental implants in one jaw to provide a solid foundation for a complete denture. The All-on-6 variant uses six implants, while All-on-x refers to an individually designed number of implants based on the needs of a particular patient.

The great advantage of these methods is that the patient receives solid teeth in just one day , even if they have very few of their own teeth or have worn a removable prosthesis for a long time.


The main differences between All-on-4 and classic removable dentures

PropertyAll-on-4/6/xClassic prosthesis
StabilityFirmly anchored in the jawFree-standing, can be moved
Comfort while eatingAbility to bite even harder foods normallyLimited functionality, dietary restrictions
AestheticsNatural appearance, looks like your own teethLess natural appearance
MaintenanceCleans like your own teethNeed to remove, clean outside the mouth
Psychological impactFeeling of “own” teeth, greater self-confidencePatients often perceive it as a temporary solution
DurabilityWith proper care, decades of useThe need for more frequent adjustments or replacements

Why choose All-on-4?

1. Fixed solution without compromise

With All-on-4/6/x, you no longer have to worry about your teeth falling out when you talk, laugh or eat. The implants hold the restoration firmly, making it feel more natural.

2. Better functionality

Unlike dentures, implants allow for real biting. No restrictions on soft foods – you can enjoy harder foods like apples, nuts or steak again.

3. Bone preservation

When a tooth root is missing from the jaw, bone is lost. Implants stimulate the jawbone in a similar way to a natural tooth, thereby preventing bone loss. Dentures do not have this effect – on the contrary, they can put pressure on the bone and accelerate bone loss.

4. Natural appearance and speech

With dentures, speech can be slurred or muffled. All-on-4 allows for completely natural speech. In addition, modern dentures look indistinguishable from real teeth.


When might a classic prosthesis be appropriate?

Although All-on-4 is significantly more comfortable and functional, there are situations where a classic removable prosthesis is a temporary or only solution – for example, in cases of serious health limitations, insufficient bone mass, or if the patient is looking for a cheaper option. In such cases, the prosthesis can be replaced with a fixed solution later.


Investing in quality of life

It is true that All-on-4 is more expensive than a classic prosthesis. On the other hand, it is an investment in the quality of life for decades. Without the need for constant extractions, without the fear of the replacement shifting, without restrictions on food – and most importantly with the feeling that your teeth are truly “yours”.
