All-on-4 Dental Implants

Miss being able to chew, talk, and smile with ease? You can return to worry-free days with dentures supported by All-on-4® dental implants.

All-on-4 dentures need fewer implants, allowing for cost savings, less invasive treatment, a better chance of candidacy, and more. 

For lasting results that improve your appearance and dental function, visit Dr. Garrett Oka, DDS in Kailua-Kona, HI.

All-on-4 vs. Traditional Dentures Understanding the Differences

Traditional Dentures...

Are Completely Removable

Traditional dentures are held in place by suction, and with dental adhesive if needed. These dentures are less secure than All-on-X options. They can still offer improved functionality and a lovely smile — just with a little less peace of mind.


Are More Price-Conscious

For patients on a tighter budget, traditional dentures are more price-conscious. Our Kailua-Kona dental office understands how stressful implant costs can be, which is why we accept financing for all dentistry treatments.


Only Address Appearance and Bite

If you need an option to improve the aesthetics and functionality of your smile, traditional dentures can suffice. However, they will not be able to improve your bone health, which can lead to bone loss and visible sinking in your features over time.

All-on-4 and All-on-X Dentures...

Offer Improved Security

A common stress for dentures patients is the issue of security. Traditional dentures may shift position, but All-on-4 dentures will remain in the same place our dentist secures them to, so that you never have to worry about losing your smile.


Look More Natural

For the most natural-looking dental results, patients prefer All-on-4. It's completely discreet, and we use high-quality materials like zirconia to ensure that your dentures resemble regular enamel. 


Function Like Real Teeth

If you want the closest thing to a natural smile, All-on-4 is the way to go. The implants root your restoration to your jaw, allowing you to chew, talk, and smile just like you used to.

What Differentiates All-on-4 From Other Dental Implant-Supported Dentures?

Dentures supported by dental implants are considered the cream of the crop for tooth replacement. Restorations attached by All-on-4 implants, however, manage to go the extra mile. That's because:

All-on-4 Requires Fewer Implants

With All-on-4, one of the biggest benefits is all in the name. It requires just four dental implants to secure a full upper or lower denture — a smaller amount than is needed for typical implant-supported dentures. And, despite using fewer implants, your All-on-4 dentures from Dr. Oka will be just as secure as other implant-supported options.

All-on-4 Is Less Intensive

Nervous about care? You may prefer All-on-4. Since it only needs four implants per arch, the treatment will be less intensive than other kinds of dental implant-supported dentures, even potentially allowing you to avoid supplemental procedures like bone grafting. This means less time in the dentist's chair for surgery, as well as a slightly easier recovery timeline.

All-on-4 Is Easier to Qualify For

Often, patients with tooth loss will also have bone recession. This can be a challenge for implant providers, because dental implants need to fuse with your jaw bone. With All-on-4, the smaller amount of implants means that you need less bone material, allowing more patients to qualify for treatment.

Protect Your Smile and Your Health With All-on-4 Dental Implants

Though traditional dentures can help with issues of insecurity, functionality, and aesthetics, each of these problems can be resolved even better with All-on-4 dental implants.

Not to mention, with All-on-4, you'll experience another advantage that traditional dentures just can't provide: improved oral health. That's because dental implants stimulate bone tissue, which often is lost when patients lose their natural teeth, experience decay, or live with dental trauma.

Are All-on-4 Dentures Stable? Yes — And It's Thanks to Osseointegration

Traditional dentures are tricky to keep in place. All-on-4 dental implants solve that problem entirely, using a process called osseointegration.

Osseointegration occurs when a dental implant fuses with your jaw and gums. In fact, the implant will become so stable that it will even functionally replace your tooth roots.

This process takes about three to six months to finish, giving you a lifetime of security and peace of mind. Once it's complete, our Kailua-Kona dentist will attach your abutments and custom dentures for a picture-perfect new smile.

Not a Candidate for All-on-4? You May Be Eligible for All-on-X

Due to factors like the amount of jawbone tissue you have, you may not be a good candidate for All-on-4 dental implants. Luckily, there is another option from the same team: All-on-X. All-on-X dental implants can also anchor a full arch restoration.

Instead of using four implants, though, they can use anywhere from six to eight. Plus, with more implants to stimulate your bone tissue, they may be able to improve your oral health more than All-on-4 implants.

Dr. Oka is happy to explain your options, as well as the benefits of each, during your consultation at his welcoming Kailua-Kona office.

Financing Available

Typically, dental insurance does not cover implants — despite the tangible benefits to your health and happiness. To give you more options, we accept financing from providers like CareCredit® and Springstone.

Understanding the All-on-4 Placement Process From Start to Finish

Dental Consultation

First, you'll visit our Kailua-Kona dentistry practice for a consultation. Dr. Oka will assess your natural teeth, gums, and bones with the help of a 3D cone-beam computed tomography scanner. Then, he'll explain your dental options.

Supplementary Treatments

Some dentistry patients will need supplemental treatment, like bone grafting or tooth extraction, before they are candidates for All-on-4 or All-on-X. Once those dental treatments are complete and the area has healed, Dr. Oka can begin the next phase.

Implant Placement

Dr. Oka will only place implants if your teeth, bone, and gums are healthy enough. The process involves making openings in your gums and bone, where he will secure the implants. The number will vary, depending on if you've chosen All-on-4 or All-on-X.

Temporary Restoration

Our dentist can attach temporary acrylic teeth made by our on-site SprintRay 3D printer to your All-on-4 dental implants, so that you'll have beautiful and functional teeth throughout your treatment. In select cases, he may be able to place your abutment and permanent restoration instead.


Over the next three to six months, your implants will undergo osseointegration, a revolutionary dentistry process that allows them to replace the natural roots of your teeth. Dr. Oka will give you clear instructions on the best way to take care of your mouth during this time.

Abutment Placement

Our dentistry practice uses abutments to secure your dental implants to your new dentures. These abutments will be completely hidden by your new dentures, for the most subtle tooth replacement treatment.

Restoration Placement

For one final thoughtful touch, we use lifelike restorations crafted from your choice of IPS e.max® or zirconia. Once they're attached to your abutments, you'll be able to enjoy renewed functionality and aesthetics.
