All-on-X
Dental Implants:
A Permanent Way to Smile Again
All-on-X is a full-arch implant restoration — a complete set of fixed teeth supported by a small number of titanium implants placed in the jawbone. The “X” simply refers to the number of implants used, which typically ranges from four to six depending on your anatomy and clinical needs.
Unlike traditional dentures, which rest on the gums and can shift or require removal at night, All-on-X restorations are permanently anchored to your jaw. You eat with them, sleep with them, and smile with them — just like natural teeth.
The prosthetic arch is made from high-strength zirconia, the strongest material used in restorative dentistry. It is custom-designed to look and function naturally, with proper proportion, color, and bite relationship built in from the beginning. You’ll see the plan and approve the design before anything is permanent — because no one should commit to a new smile they haven’t already seen.

- Good option if not a candidate for fixed implants
All-on-X Full Mouth Implants
(Fixed)- 4+ implants per arch for permanent teeth
- Fixed/permanent (never removed)
- Temporary teeth provided during 4-6 month healing
- Premium zirconia prosthetics for natural appearance
- Doesn’t cover roof of mouth

- Customizable color, shape, and fit
Is This the Right Option for You?
For patients who have lost most or all of their teeth, All-on-X offers a fixed, natural-looking full-arch restoration supported by just four to six implants. No nightly removal. No adhesive. No more adapting around your smile.
All-on-X is designed for patients who have experienced significant tooth loss — or who are facing it — and want a permanent, fixed solution rather than a removable appliance.
Many patients who come to us for All-on-X have been quietly adapting for years. They describe avoiding certain foods, hiding their smiles in photographs, and carrying a low-grade self-consciousness into everyday social situations. Most assumed this was simply how things would be from here on.
All-on-X was developed for exactly those patients. It doesn’t just restore teeth — it restores the ability to eat, speak, laugh, and smile without thinking about it first.
- Lost most or all of your teeth in one or both arches
- Multiple failing, cracked, or severely decayed teeth
- An existing denture that no longer fits or functions well
- Adequate jawbone to support implants (confirmed by 3D imaging)
- Good general health and no uncontrolled systemic conditions
- A desire for a permanent, fixed restoration
- “I’m nervous about the procedure.” — Completely understandable. Sedation is available at every level, and our team’s job is to make sure you feel calm and safe from your first phone call forward.
- “I’m not sure I can afford it.” — A real concern for many of our patients. We talk openly about cost, share financing options, and help you understand the long-term picture before any decisions are made.
- “What if I don’t like how it looks?” — You’ll see and approve your restoration digitally before anything becomes permanent. We don’t proceed until you’re confident.
- “I’ve delayed care a long time.” — You’re far from alone. Many of our All-on-X patients waited years before finding a practice they felt comfortable in. There’s no judgment here — just a starting point.
Not every full-arch restoration is the same. Dr. Mendelsohn will evaluate your jawbone, health history, and goals to recommend the most appropriate solution. Here’s an overview of the fixed implant-supported options we offer:
All-on-4
Four implants per arch, with two placed at a slight angle in the back to maximize contact with available bone. A proven, widely used approach — particularly effective for the lower jaw.
All-on-6
Six implants per arch for greater load distribution and stability. Often recommended for the upper jaw, where bone density is typically softer, or for patients who want maximum support.
Crown & Bridge on Implants
The closest option to natural teeth. A fixed bridge supported by six to eight implants per arch. Easiest to clean and most similar in feel to having individual teeth.
A note on implant-supported hybrid dentures: For some patients — particularly those with significant bone loss or limited manual dexterity — a hybrid denture (screw-retained, removed only by your dentist) may be the most appropriate option. We’ll walk through all options at your consultation so you can make a fully informed decision.
Traditional dentures have helped a lot of people, and for some patients they remain a reasonable option. But many of the patients we see have spent years working around the limitations of removable dentures — and didn’t realize there was another way. The comparison below is meant to clarify the practical differences, so you can make a fully informed decision about what’s right for you.
| Feature | All-on-X Implants | Traditional Dentures |
| Fixed in place | Permanent — non-removable | Removable |
| Stimulates jawbone | Yes | No — bone loss may continue over time |
| Requires adhesive | No | Often Yes |
| Chewing ability | Near-normal | Reduced for many patients |
| Slippage when speaking | None | A common concern |
| Nightly removal | Not required | Typically recommended |
| Implant longevity | 20+ years typical with proper care | Fit and lining changes over time |
| Appearance | Custom zirconia, shade-matched | Varies |
Every All-on-X case at our practice begins long before any treatment is performed. Our approach is built on a simple idea: we show you what we see. By the time you sit in the chair for your procedure, you’ve already seen the imaging, reviewed the plan, and approved the design. No “trust me” required — and no surprises along the way.
- Consultation & 3D Imaging
We start with a thorough evaluation including 3D X-rays and a digital scan of your mouth. This gives Dr. Mendelsohn an accurate picture of your available bone, anatomy, and the ideal implant positions for your case. You’ll see the images alongside us and have everything explained in plain language — because understanding your own situation is the foundation of every good decision that follows.
- Digital Treatment Planning & Smile Design
Using AI-assisted design software, we plan your restoration digitally before anything is touched. You’ll see a simulation of your outcome — the shape, proportion, and appearance of your new teeth — and have input before any commitment is made.
- Implant Placement Surgery
The implants are placed under anesthesia. Sedation is available for any level of anxiety — from mild nervousness to significant dental fear. A transitional prosthetic is placed the same day so you leave with a full set of teeth.
- Healing & Osseointegration
Over the following three to four months, the implants fuse with your jawbone — a process called osseointegration. During this time, you’ll follow a softer diet and attend follow-up visits. We monitor your healing closely throughout.
- Final Restoration Delivery
Once your implants are fully integrated, your permanent zirconia prosthetic is placed. Before final seating, you’ll have the chance to evaluate the look and fit — we want you to love what you see before anything is finalized.
- Long-Term Maintenance
All-on-X restorations require dedicated home care and regular professional maintenance. We’ll show you exactly how to clean your restoration with the right tools — a water flosser, super floss, and interdental brush — and schedule your ongoing visits to protect your investment for the long term.
One of the most important things we share with every implant patient: the work does not end at delivery. Long-term success depends on how well the restoration is maintained at home and how consistently patients keep their professional maintenance appointments.
Unlike natural teeth, implants cannot develop cavities — but the gum tissue and bone around them are still vulnerable to inflammation and infection if hygiene is neglected. Patients who stop caring for their implants after placement are at the highest risk for long-term complications.
What we recommend for daily care: A water flosser (Waterpik), super floss to thread under the arch, and an interdental brush for accessing smaller spaces. We will demonstrate the proper technique at your delivery appointment and review it at every maintenance visit.
Fixation screws will occasionally require replacement at a modest additional cost — this is normal and expected as part of long-term care. Hybrid dentures are typically removed annually by our team for professional cleaning and evaluation.
With proper care, the implants themselves can last a lifetime. The prosthetic arch is designed for many years of use, though it may be updated over time as wear occurs or as your needs change.
What Patients Ask Us About All-on-X
These are the questions we hear most often — answered honestly, the way we’d explain them in the office.
- What does All-on-X mean?
All-on-X refers to a full-arch tooth replacement procedure in which an entire set of teeth is supported by a fixed number of implants — typically four to six — placed in the jawbone. The “X” represents the number of implants used. Rather than replacing each tooth individually, All-on-X uses strategically positioned implants to anchor a full prosthetic arch that is permanently fixed in place.
- What's the difference between All-on-4 and All-on-X?
All-on-4 is a specific version of the All-on-X concept that uses exactly four implants per arch. All-on-X is the broader category that includes any number of implants — four, six, or more — depending on what the patient’s jawbone and clinical situation require. Some patients benefit from six or more implants for greater stability and load distribution, particularly in the upper arch where bone is naturally softer.
- How many implants does All-on-X require?
Most All-on-X procedures use four to six implants per arch. Four implants are often sufficient for the lower jaw; the upper jaw may require more due to softer bone density. Dr. Mendelsohn uses 3D digital imaging to evaluate your specific anatomy and determine the ideal number and placement before any treatment begins.
- Are All-on-X implants removable?
No. All-on-X restorations are fixed in place — screw-retained to the implants and removable only by your dentist. This is one of the most significant advantages over traditional dentures. You eat, speak, and sleep with them in place exactly like natural teeth. There is no adhesive, no nightly removal, and no risk of slippage.
- What are the downsides of All-on-4 dental implants?
Like any surgical procedure, All-on-4 involves a healing period and requires commitment to proper maintenance. Some patients experience temporary soreness, swelling, or dietary restrictions during recovery. The prosthetic arch will eventually require servicing over the years. And because the restoration is supported by four implants rather than six or more, some patients may be better candidates for All-on-6 depending on their bone structure. A thorough consultation and 3D imaging help determine which option is right for you.
- Do All-on-4 dental implants hurt?
Like any surgical procedure, All-on-4 involves a healing period and requires commitment to proper maintenance. Some patients experience temporary soreness, swelling, or dietary restrictions during recovery. The prosthetic arch will eventually require servicing over the years. And because the restoration is supported by four implants rather than six or more, some patients may be better candidates for All-on-6 depending on their bone structure. A thorough consultation and 3D imaging help determine which option is right for you.
- What is the recovery time for All-on-X?
Initial healing typically takes one to two weeks, during which most patients follow a soft-food diet. Full osseointegration — the process by which the implants fuse with the jawbone — takes approximately three to six months. Most patients return to normal daily activity within a week or two and leave their procedure with a full set of functional teeth the same day of surgery.
- How long do All-on-X dental implants last?
The titanium implant posts have an excellent long-term track record and can last 20, 30, or even 40+ years with proper care. The prosthetic arch is made from high-strength zirconia and designed to last many years, though it may require maintenance or updates over time depending on wear. Long-term success depends most on consistent home care and regular professional maintenance visits.
- How do you clean All-on-X implants?
Because All-on-X restorations are fixed in place, cleaning requires dedicated tools: a water flosser (such as a Waterpik), super floss to thread under the arch, and an interdental brush to access smaller spaces. Regular professional cleanings at Serenity Smile Designs are essential — your hygiene visits will include specialized cleaning protocols specific to implant restorations.
- What are the benefits of All-on-X?
All-on-X provides a fixed, stable full-arch restoration that functions and looks like natural teeth. Benefits include improved chewing ability and nutrition, restored confidence in speaking and smiling, elimination of denture slippage, preservation of jawbone, no nightly removal, and a natural-looking result made from high-strength zirconia. For patients who have lived for years adapting to tooth loss, it is often genuinely life-changing.
- What happens to dental implants after 20 years?
Titanium implant posts have an excellent long-term track record. Many implants last 20, 30, or even 40+ years with proper care and maintenance. The prosthetic arch above the implants may need to be updated or serviced over time due to normal wear. The most important factor in implant longevity is consistent oral hygiene and regular professional follow-up.
- What I wish I knew before getting dental implants?
Most patients wish they had started sooner. Common reflections include: the process was more comfortable than they expected; recovery was more manageable than feared; the impact on daily quality of life — eating, smiling, speaking — was greater than anticipated; and ongoing maintenance is genuinely important. At Serenity Smile Designs, we walk every patient through realistic expectations, timelines, and long-term care before any treatment begins. There should be no surprises.
- What's better than All-on-4 implants?
“Better” depends entirely on the individual patient’s anatomy, bone quality, and goals. For some patients, All-on-6 provides greater stability and is the superior option. For others with adequate bone, a crown-and-bridge-on-implants approach — which most closely replicates individual natural teeth — may be ideal. The best option is determined through a comprehensive evaluation, not a general ranking. We’ll help you understand which solution fits your situation specifically.
