Hello,

I’m Director Lee Juri of Seoul Vardi Dental Clinic.

“Is there any option besides dentures at my age?”

“Implants are too many, so I can’t afford the cost...”

For people whose teeth have almost all been lost, those who could barely eat because their teeth were loose every day, and those who felt uncomfortable even meeting other people, there are probably many of you like this.

But if you’re thinking about placing full-mouth implants, the cost is no small matter. The long treatment period can also be burdensome, making you hesitate.

At times like this, there is a method that has recently been drawing attention. It is the treatment that restores all missing teeth with just 4 implants: All-on-4.

Is this really possible?

How can 4 implants support the entire mouth?

How is it different from dentures?

About All-on-4, which you may be hearing about for the first time, I have organized in detail who it is mainly for, as well as its pros and cons.

If you are considering full-mouth implants, be sure to read this!!!!

It may become a completely new option.

All-on-4

All on 4

When teeth are lost throughout the mouth, the first treatments that usually come to mind are dentures or implants.

One treatment that can be another alternative for these patients is the All-on-4 treatment method.

all on 4

As the name suggests, it means a method that restores all teeth with just 4 implants.

In general, if you assume full-mouth implant treatment, about 8 to 10 implants are needed.

However, All-on-4 is designed so that the entire mouth can be supported by placing only half of that, 4 to 6 implants.

It is often described as slightly different from the so-called snap-on dentures...

All-on-4 does not require dentures; it is a method that restores the entire dentition with just 4 implants.

Snap-on dentures involve placing implants and then fitting dentures on top of them.

Who is it suitable for?

  • Those who have lost almost all teeth, or who need all teeth extracted
  • Those whose existing dentures are uncomfortable and unstable
  • Those whose jawbone has been severely resorbed, making regular implants difficult

It is not for everyone.

In particular, patients who have worn dentures for a long time. Patients who have insufficient molar bone and for whom implant surgery is difficult are being recommended for this treatment.

Because analysis is important, CT scans must also be performed in advance.

Above all, since only 4 implants are placed instead of a full set, the burden of surgery is reduced.

It is also more economical.

It offers better stability than dentures, and its biggest advantage is that you do not need to take it in and out.

Visually, it is also more natural than dentures.

Because it can be used like your own teeth, it can also restore functions such as pronunciation and chewing ability.

As a drawback, inflammation can occur just like with implants, and cleanliness must be maintained.

This applies to all dental treatments, so I will not mention it further.

In the past, when all teeth were lost, the only alternatives were dentures or full-mouth implants,

but now there is the option of “All-on-4.”

Less burdensome than full-mouth implants, better for chewing than dentures, and convenient to use.

I think those are the 3 things to remember.

Every treatment has pros and cons, and the suitable method can differ depending on each person’s condition.

If you are struggling with total tooth loss, find the treatment that is right for you through a thorough consultation and diagnosis!

This was Lee Juri.
