What’s Implant?

Have you heard of “implant”?


Implant is the dental treatment burying artificial tooth root in the jawbone where tooth is lost, and attaching artificial tooth on that.

With the implant treatment, you can have strong, natural-looking, and beautiful tooth. And you can enjoy the meal compared to denture, bridge, or post crown.

Structure of implant is as shown on the picture.

We Ryouki Dental Clinic (Higashi-Osaka Implant Center) offer many implant treatments to spread the treatment and to provide patients with fulfilling lives.

Pros of Implant Treatment

1. You can have natural-looking tooth close to the tooth you lost.

In the implant treatment we bury strong artificial dental root, so you have strong and beautiful tooth without discomfort and you can enjoy eating compared to denture, bridge, or post crown.

2. Strong biting force

With denture, you can bite with 30% of your original tooth force. While with implant, there are more than 80% of functional recovery.

3. Prevention of disuse atrophy of bone

In human body unused tissues slim down, and it is called “disuse atrophy”.
In false tooth, only indirect force is applied to jawbone, so jawbone gets slim and it makes the old-looking face.
While in implant, direct force is applied to jawbone as well as the original tooth, disuse atrophy doesn’t occur and you can keep your young-looking face.

4. Stop the occlusion collapse

After you lose tooth, left teeth have burden beyond necessity, and “occlusion collapse” occurs losing other teeth at an accelerated pace.
Once this occlusion collapse occurs it is hard to stop, but implant treatment is the only solution to stop this.

5. You can bite without applying burden to other teeth.

If you lose tooth, burden is applied to other teeth when you bite. It deteriorates other teeth, and trouble spread to teeth other than original teeth in the end.
Implant treatment can bring the affected teeth back to mostly original states without applying burden to other teeth.

Many kinds of Implant

Implant working as solo

Lost tooth or unhealthy tooth can be replaced by implanted tooth.


Implant as Bridge

Applying implant treatment to 2 teeth, 3 teeth can be created.


Implant to support denture

Applying implant treatment to 2 teeth, 3 teeth can be created.


Comparison with Denture

Strong biting force

With denture, you can bite with 30% of your original tooth force.
While with implant, there are more than 80% of functional recovery.

Good wearing feel

A big difference between denture and implant is the wearing feel.
With denture you always feel something attaches, but with implant you forget you attach something.

No discomfort

Patients with denture have always stress with the discomfort.
While in implant, you feel natural without any feelings of discomfort.

Chewy texture

One of way of enjoying food is feeling chewy texture.
With denture with less transmission of force, you have to care when you chew hard food and you can’t enjoy the chewy texture.
While with implant which strong tooth root is directly buried into jawbone, you can enjoy chewy texture of the food itself as much as want.

Implant Glossary


Osseointegration is the direct structural and functional connection between living bone and
titanium, the surface of a load-bearing artificial implant.
Titanium and bone connect after 3 to 4 weeks of implant treatment, and the ratio contact gets high after 3 months of it.
In a few months after treatment, we have to be careful not to apply burden on implant. For this, root of implant should be covered by gum after burying implant during the healing period until osseointegration occurs. (5 to 6 months for upper jaw, 3 to 4 months for lower jaw.)

GBR(Guided Bone Regeneration)

When width or height of bone is not enough in implant surgery, GBR(Guided Bone Regeneration)is applied wrapping special cloth around alveolar bone to reproduce bone and make alveolar bone thick.
Implant is buried in the hole where tooth was extracted. Mostly the hole is bigger than implant, so implant is covered after being buried.
If we open the gum six months after surgery, bone is reproduced in the gap between the hole and the implant.

Sinus lift

There is a hole called sinus maxillaris on the bone of upper jaw. Due to the sinus maxillaris, the bone of upper jaw is much thinner than the one in lower jaw, so when implant is buried in the upper jaw, there are more restrictions compared to being buried in the lower jaw.
There are cases the bone of upper jaw has not enough thickness, and bone should be added. Sinus lift is applied in this case.
In Sinus lift, mucosa of sinus maxillaris is lifted by separating from the bottom of sinus maxillaris. To support this, own bone or bone prosthetic material is transplanted in the gap, and thickness of bone for implant is secured.

Socket lift

Socket lift is applied to upper jaw as sinus lift. But difference is using the spring of membrane in the bottom of upper jaw (schneiderian membrane) breaking alveolar bone without exposing sinus maxillaris.
Specifically, we expose alveolar bone opening up gum in upper jaw, hammer the bone in the bottom of sinus maxillaris with special equipment (osteotome), and separate the membrane pushing up revealed schneiderian membrane to sinus maxillaris.
In the gap between separated schneiderian membrane and the bottom of sinus maxillaris, implant is buried after filling own bone or artificial bone with injector. And the mucous membrane (gum) is stitched up after checking the initial fix.
Compared to sinus lift, socket lift is more adapted because it needs less burden temporally and physically because exposing sinus maxillaris is unnecessary.

Process of Implant Treatment

There might be bit difference depending on the bone state, but the basic process of treatment is as follows:

Screening and diagnose

After screening including X-ray, we plan the treatment.
We also diagnose if implant treatment is feasible or not.


CT shooting

Dental CT camera shoot the part implant will be buried in 3D.



We have surgery to bury implant to jawbone.
Depending on the case we have dental casting and create false tooth at the same time.
We will attach false tooth on the same day.


Have dental casting → attach false tooth

We have dental casting and create false tooth.
It will take 1 to 2 weeks from having dental casting to attach the false tooth.



We have checkup once in 3 month to see if the implant was buried become like periodontal disease treatment (peri-implantitis) or if there are any troubles in other teeth. Taking check-ups are necessary condition to take warranty of implant treatment.


Process of attaching implant
1. State of losing a teeth

This is the state of losing teeth due to accident or periodontal disease.

2. Create a hole for implant body

We open a small hole in the jawbone with drill.

3. Bury a implant and stitch it up.

We bury a root part of implant body in the hole, and stitch it up covering with gum.

4. After 3 to 4 months, attach the base for upper part.

After jawbone and implant body are connected, we install the base part to attach upper part of implant (tooth part).

5. Make the mold of base and create the upper part.

We make the mold of base installed in 4, and create the upper part.

6. Attach the upper part to the base, and complete!
