Introducing All-on-X System as an Alternative to Dentures

Hello. Good Day is always here to share

sincere stories about dentistry.

Yonsei Good Day Dental Clinic has newly introduced the

a treatment option that may become a new choice for edentulous patients:

the All-on-X system.

All-on-X was introduced for people who have lost most of their teeth,

or whose prognosis for several teeth is poor,

and who feel overwhelmed because they need comprehensive treatment.

Rather than the conventional method of placing one implant per tooth,

it is designed as a structure that supports the entire set of teeth with 4 to 6 implants.

It is a fixed full-arch implant treatment in which implants are strategically placed,

taking angle and position into consideration,

so that the function of the full dentition can be restored with the minimum number of implants.

Because the full prosthesis is supported by 4 to 6 implants,

it can reduce the burden of surgery and cost,

and has the advantage of restoring more than 80 to 90% of the function of natural teeth.

• Mandibular All-on-X completed (2025.12)

In some cases, a temporary tooth can be placed on the same day,

and it is a treatment option that allows a relatively quick return to daily life.

“You mean it’s just implant dentures?”

You may think that.

That is because implant dentures also involve placing only 4 to 6 implants before fitting dentures.

However, All-on-X is different from the structure itself.

Implant dentures use implants as a “fixation device”

to stabilize removable dentures,

whereas All-on-X directly connects a fixed prosthesis to the implants,

so it is not a structure that the patient removes and inserts on their own.

In other words,

implant dentures → removable

All-on-X → fully fixed

is the difference.

A fully fixed prosthesis provides more stable force transmission during chewing,

has less foreign-body sensation relatively,

and can be expected to feel similar to natural teeth.

Of course, rather than saying one treatment is simply “better,”

it is important to comprehensively determine the appropriate approach based on the patient’s alveolar bone condition, general health, and ability to maintain care.

● Cases with severe mobility of multiple teeth due to periodontal disease

● Cases of significant discomfort from long-term denture use

● Cases where multiple teeth are damaged

and overall reconstruction is needed

All-on-X may be a good option.

Problems involving the full dentition are not only about chewing function,

but are also connected to speaking, confidence in appearance, and comfort in daily life.

The key to All-on-X treatment

is not “placing many implants,”

but how it is designed and how the forces are distributed.

Yonsei Good Day Dental Clinic introduced the All-on-X system

to provide more systematic and stable full-mouth treatment,

and through precise diagnosis,

it establishes a treatment plan in a way that does not overstrain the patient,

after fully considering the patient’s alveolar bone condition, occlusion, and general health.

Losing all of one’s teeth can be a major burden

both physically and psychologically.

Yonsei Good Day Dental Clinic will continue researching treatment methods that are a little more comfortable and a little more stable,

so that patients do not have to carry that burden alone 😄

Recovery process, effects, and side effects may vary depending on the oral condition,

so consultation with a medical professional is absolutely necessary.
