About All-on-4
All-on-4 is an implant treatment for those suffering with dentures or those diagnosed with tooth decay or gum disease that prevents them from keeping their teeth. The All-on-4® treatment concept is Nobel Biocare's solution.

It is a completely new concept procedure that restores chewing function and aesthetics on the day of surgery by fixing the full bridge with 4 implants for the lower jaw and 4 to 6 implants for the upper jaw.
Because of this, the treatment period was very long and the Treatment fee was very high. With All-on-4, the Treatment fee can be reduced and the treatment period can be shortened. With All-on-4, the Treatment fee can be reduced and the treatment period can be shortened.
All-on-4 trouble
Examining the cases of patients who had problems and visited the clinic with a second opinion, the most common post-treatment trouble with All-on-4 was the "final prosthesis" (tooth part).

Re-doing implant treatment is very difficult. To avoid regret, please decide on a clinic based on the appropriate Treatment fee and correct information.
At All-on 4 Clinic, we strive to provide medical consultations that suit the patient. We will explain everything until the patient is satisfied, so please have a free counseling session first.
Why does trouble occur?
This is because surgery-led operations are often performed (implants are placed where there is bone, relying on the experience of a dentist, a mold is made, and the tooth part is later created by a technician).
In terms of architecture, it is like putting the pillars in first, without drafting blueprints, and then building the house.
At All-on-4 Clinic, after first creating a [Radiographic Guide], we perform prosthesis-led treatment in which surgery is performed after making an implant placement plan with DTX studio™ implant (implant simulation software).
About a radiographic guide
A radiographic guide is like a transparent denture, reproducing the final prosthesis, used to determine the implant placement position. It is placed in the patient's mouth and check if the tooth shape and alignment match the patient's face.
By doing so, the patient can get an idea of the final finish.
If all goes well, a CT scan is taken with the radiographic guide in the patient's mouth and DTX studio™ implant is used to plan the implant placement position.



Free first counseling session
First of all, please feel free to come for a counseling session.
It is completely free of charge, and you are welcome to come just to hear an explanation.
In our counseling room, the clinic director will carefully listen to you, perform a CT scan, then conduct an examination, give a diagnosis, and create and propose a treatment plan that will restore your smile in as short as just 24 hours after the procedure.

01. Non Gum
Our All-on-4 is different from the traditional All-on-4 treatment, where in all cases the bone is shaved and artificial gingiva is applied.
With precise examination and diagnosis, there are about 10% of cases that can be done without artificial gingiva.


02. Zygomatic technique
In some cases, recession in the upper jaw bone can prevent the application of All-on-4. However, we have a method that uses long zygomatic implants that are fixed in the cheekbones to realize All-on-4 for everyone.
03. Facility
All-on-4 CLINIC awaits you in a sophisticated space on the 3rd floor of the building that houses the Tiffany Bridal Boutique near the center of Ginza. You can take your time with the consultation, without worrying about other patients, in our counseling room.


04. General anesthesia
The procedure begins with the introduction of anesthesia selected by the anesthesiologist according to the patient's procedure and wishes.
05. Warranty / Follow-up services
From the postoperative period onwards for the rest of your life, we will provide post-treatment support according to your lifestyle. We guarantee a complete maintenance program and reliable follow-up for wear and tear of the superstructure.

02. Zygomatic technique
In cases where the maxillary bone has atrophied to the extent that All-on-4 cannot be applied, it is possible to use All-on-4 with all patients by making full use of "zygoma Implants" which implants a long implant in the cheekbone.

Doctor
Ryoji Kitami

I have gained experience in implant treatment in the Implantology Department of a university hospital and have helped with many patients with serious complaints.
I believe that my role is to support those who have unfortunately lost their teeth, or have been told that they cannot keep their teeth, so that they can once again enjoy delicious meals and live with a smile on their face.
In addition to utilizing the skills I have built up in implantology at the university hospital, I also provide a wide range of general dentistry services other than implants, so please feel free to contact me with any concerns or questions you may have.
Kiyoto Mizutani

I belong to various academic societies and study groups, constantly learning about medical care and striving for "the treatment I would personally want to receive and the treatment I would want my family to receive," and I continue to devote myself to my studies.
In addition to treatment for dental caries and periodontal disease, I can also provide implants, esthetic treatment, and orthodontic treatment.
The mouth is the entrance to good health. I will do my best to help my patients have a lifetime of smiles, health and beauty in their mouths.
I strive to make medical treatment a "pleasant time" rather than a "painful time," so even those who are uncomfortable with dental treatment can come to our clinic with peace of mind.
