10 Questions About All-on-4 Dental Implants—Answered by a Henderson Implant Dentist
Everything You Need to Know Before Replacing Missing Teeth
If you’ve lost most or all of your teeth—or you’re tired of struggling with loose dentures—you’ve probably heard about All-on-4 dental implants. This advanced treatment has helped millions of patients regain the ability to eat comfortably, smile confidently, and enjoy life without removable dentures.
But before making any major dental decision, it’s natural to have questions.
At Marielaina Perrone, DDS, we believe informed patients make confident decisions. Below are answers to the ten questions we hear most often from patients considering All-on-4 dental implants in Henderson, Nevada.
1. What Are All-on-4 Dental Implants?
All-on-4 is a full-arch tooth replacement solution that uses four strategically placed titanium dental implants to support a fixed bridge of replacement teeth.
Unlike traditional dentures that rest on the gums, All-on-4 restorations are securely attached to dental implants, providing exceptional stability and function.
For many patients, temporary fixed teeth can often be placed the same day as surgery.
2. Who Is a Good Candidate?
You may be a candidate if you:
- have multiple missing teeth
- have severely damaged or failing teeth
- wear removable dentures
- want a permanent alternative to dentures
- have adequate jawbone
- are in generally good health
Even patients with moderate bone loss may still qualify because the angled placement of the posterior implants often reduces the need for bone grafting.
A comprehensive examination and CBCT scan determine whether All-on-4 is appropriate.
3. How Long Does Treatment Take?
The surgical appointment is usually completed in a single day.
Many patients leave wearing a temporary fixed restoration while the implants heal.
After approximately 3 to 6 months, once osseointegration is complete, your custom-designed final bridge is fabricated and attached.
What to Expect with All-on-4® or All-on-6 Dental Implants
Select each stage to understand how full-arch implant treatment typically progresses.
The same overall journey generally applies to All-on-6 treatment; the main difference is that six implants are used instead of four, with the number and position selected according to your anatomy, bone support, bite, and restorative plan.
1. Consultation and Full-Arch Planning
Determining whether four or six implants are appropriate
Treatment begins with a comprehensive examination, medical history review, bite evaluation, and three-dimensional imaging when appropriate. The condition of the remaining teeth, gum health, bone volume, facial support, and restorative goals are evaluated before choosing an All-on-4, All-on-6, or another full-arch approach.
✓ Comprehensive oral and periodontal examination
✓ Digital X-rays or 3D CBCT imaging when appropriate
✓ Evaluation of bone, bite, smile, and facial support
✓ Personalized recommendation for implant number and position
“The decision between four and six implants should never be based on a label alone. It should be based on the anatomy, forces, and restorative needs of the individual patient.”
— Marielaina Perrone, DDS
2. Preparing the Mouth
Creating a healthy foundation for full-arch treatment
Depending on your condition, preparation may involve treating infection or gum inflammation, removing teeth that cannot be saved, and reshaping or grafting bone when necessary. Some patients can proceed directly to implant placement, while others benefit from preliminary treatment first.
✓ Removal of failing teeth when necessary
✓ Treatment of active infection or periodontal disease
✓ Bone smoothing or grafting in selected cases
✓ Review of temporary-tooth options
3. Implant Placement and Temporary Teeth
Establishing support for the new arch
Four implants are used in the All-on-4 treatment concept, while an All-on-6 approach uses six. When initial implant stability and other clinical criteria are met, a fixed provisional restoration may be attached on the day of surgery. Not every patient qualifies for immediate loading, so temporary treatment must be individualized.
✓ Four or six strategically planned implants
✓ Local anesthesia and individualized comfort measures
✓ Fixed provisional teeth may be possible in qualifying cases
✓ Detailed postoperative and diet instructions
“Same-day teeth can be an important benefit, but the biology still has to be respected. A provisional smile must protect the implants while healing takes place.”
— Marielaina Perrone, DDS
4. Healing and Osseointegration
Protecting the implants while bone integration develops
During the next several weeks and months, bone heals around the implants. Patients are commonly instructed to follow a modified diet and avoid placing excessive force on the provisional restoration. Follow-up visits allow the bite, tissues, hygiene, and implant stability to be monitored.
✓ Bone gradually integrates around each implant
✓ A soft or modified diet may be required
✓ The provisional restoration and bite are monitored
✓ Home-care techniques are reviewed and refined
“The temporary teeth may look complete, but the implants underneath are still healing. Protecting that phase is essential to long-term success.”
— Marielaina Perrone, DDS
5. Designing the Final Full-Arch Restoration
Refining appearance, comfort, speech, and bite
After healing is confirmed, the final restoration is designed using detailed records and the information learned from the provisional teeth. Tooth shape, shade, smile width, lip support, speech, cleaning access, and bite forces are considered before the definitive full-arch restoration is completed.
✓ Evaluation of implant stability and tissue health
✓ Customized tooth shape, shade, and smile design
✓ Refinement of speech, comfort, and facial support
✓ Final fit and bite verification
6. Long-Term Full-Arch Maintenance
Protecting the implants, restoration, gums, and bone
All-on-4 and All-on-6 restorations require lifelong professional and home maintenance. The prosthesis itself cannot develop cavities, but plaque, inflammation, peri-implant disease, wear, loosening, or bite changes can still occur. Regular examinations help detect problems before they become more difficult to manage.
✓ Clean beneath and around the restoration every day
✓ Attend recommended professional maintenance visits
✓ Monitor implant bone levels, tissues, and bite
✓ Wear a protective appliance if recommended
“Whether a restoration is supported by four implants or six, long-term success still depends on healthy tissues, a balanced bite, and consistent maintenance.”
— Marielaina Perrone, DDS
How All-on-6 Fits Into This Timeline
The consultation, surgery, provisional restoration, healing, final-restoration, and maintenance stages are generally similar for All-on-4 and All-on-6 treatment. All-on-6 uses two additional implants, but six implants are not automatically better for every patient. The appropriate number and arrangement depend on available bone, anatomy, bite forces, restoration design, and the treating clinician’s plan.
Individual treatment varies. Immediate provisional teeth are available only when clinical criteria are met and adequate implant stability is achieved. Some patients require additional procedures or healing before receiving temporary or final teeth.
4. Is the Procedure Painful?
Most patients are pleasantly surprised.
Treatment is performed using local anesthesia and, when appropriate, sedation to maximize comfort.
Following surgery, most patients describe discomfort as mild to moderate and manageable with prescribed or over-the-counter medications.
Many patients report the procedure was easier than expected.
5. How Long Do All-on-4 Dental Implants Last?
With proper care, the dental implants themselves can often last for decades.
Your prosthetic bridge may eventually require maintenance or replacement because of normal wear, but excellent home care and regular professional maintenance greatly improve longevity.
6. Do All-on-4 Implants Prevent Bone Loss?
Yes.
One of the greatest advantages of implant dentistry is that implants stimulate the jawbone similarly to natural tooth roots.
This stimulation helps:
- preserve bone volume
- maintain facial support
- reduce premature facial aging
- improve long-term oral health
Traditional dentures do not provide this benefit.
7. Are All-on-4 Better Than Dentures?
For many patients, yes.
Compared with removable dentures, All-on-4 typically provides:
- greater stability
- improved chewing ability
- better speech
- increased comfort
- no adhesives
- no slipping
- improved confidence
- a more natural feel
Many patients say All-on-4 feels much closer to having natural teeth again.
8. How Do I Care for My New Smile?
Daily maintenance includes:
- brushing twice daily
- cleaning beneath the bridge using recommended devices
- routine professional cleanings
- regular dental examinations
Proper maintenance is essential for long-term success.
9. How Much Do All-on-4 Dental Implants Cost?
The investment varies based on several factors, including:
- whether one or both arches are treated
- need for extractions
- implant complexity
- type of final restoration
- additional procedures
Although All-on-4 has a higher initial investment than traditional dentures, many patients consider it an investment in long-term health, comfort, function, and confidence.
Flexible financing options are available to help make treatment more affordable.
