01
Which teeth can be retained
Existing teeth are assessed individually. Removing teeth solely to fit a fixed concept is not an automatic starting point; the treatment plan follows the clinical findings.

Your treatment options
What we assess before recommending All-on-4
A full-arch plan considers which teeth can be retained, the available bone, the final bite and how the restoration will be cleaned each day.
02
Fixed or removable
A fixed implant-supported restoration and a removable denture differ in surgery, cleaning, repair, cost and how they feel in daily life.
03
A maintainable final design
The full-arch restoration must allow cleaning underneath and stable bite contacts. Maintenance continues after the final teeth are fitted.
Treatment options
All-on-4, All-on-6 and other treatment options
All-on-4 uses four implants in one jaw. If six or eight implants are recommended, we explain that as an All-on-6 or All-on-8 plan with a separate estimate.
All-on-4
A connected zirconia full-arch restoration supported by four implants in one jaw.
¥3,300,000 per arch, including tax.
All-on-6
Six implants may be planned when additional support is appropriate for the anatomy and restorative design.
¥3,960,000 per arch, including tax.
All-on-8
Eight implants may be considered in selected plans. More implants are not automatically better; the anatomy and restorative plan determine the proposal.
¥4,840,000 per arch, including tax.
Removable denture or staged care
A removable denture, treatment of selected teeth or a staged plan may better match medical, financial or cleaning priorities.
After your examination, we will explain the recommended option, total fee and expected schedule before you decide.
Examination and treatment planning
Planning the implants and new teeth together
Before surgery, we assess speech, appearance, bite and access for daily cleaning. The findings guide both the implant positions and the design of the new teeth.
- Prognosis of each remaining tooth and active infection
- Bone volume, sinus and nerve anatomy on CT
- Lip support, tooth display, speech and restorative space
- Bite, jaw relationship and clenching or grinding
- Ability to clean beneath the full-arch restoration

Treatment details
Fees, treatment time and possible risks
The figures below are general guides. After examining you, we will provide a written estimate and expected schedule.
- Treatment
- Placement of four implants in one jaw to support a connected, fixed full-arch restoration. Treatment includes surgery and subsequent restorative stages.
- Fees
- Self-pay care. All-on-4 is ¥3,300,000 per arch including tax. All-on-6 is ¥3,960,000 and All-on-8 is ¥4,840,000 per arch. If bone augmentation is needed, GBR starts from ¥77,000, a socket lift is ¥198,000 and a sinus lift is ¥275,000. Other additional procedures are included in the written estimate.
- Time and visits
- Usually several months and multiple visits. The schedule and number of procedures vary with the bone, healing, temporary restoration and any grafting.
- Possible risks and side effects
- Surgery can cause swelling, pain, bleeding and infection. Nearby nerves or blood vessels may be injured, and an implant may fail to integrate or later lose stability. Medical conditions, smoking and limited bone can affect suitability. The restoration requires daily cleaning and regular professional maintenance.
Amounts include tax. Self-pay care is not covered by Japanese public health insurance. When insured care may apply, eligibility and cost depend on the diagnosis and your insurance status.

Frequently asked questions
Questions about All-on-4
Does All-on-4 use four implants?
Yes. All-on-4 uses four implants in one jaw. If examination shows that six or eight implants are recommended, we will explain that as an All-on-6 or All-on-8 plan with a separate estimate.
Will I have fixed teeth on the day of surgery?
Not in every case. The timing and type of temporary restoration depend on implant stability, bone and the surgical findings.
Can I clean under a fixed full-arch restoration?
Yes, but it requires specific brushes or cleaning aids and regular professional maintenance. The restoration shape is planned with cleaning access in mind.
Is a denture still an option?
Yes. A removable denture may avoid implant surgery and can be appropriate depending on health, anatomy, priorities and budget.
Can I start with an online consultation?
Yes. Photographs and existing records can help with an initial discussion, but the final diagnosis and estimate require an in-person examination and CT review.
