For patients facing the loss of most or all of their upper or lower teeth, the All-on-X implant protocol is one of modern dentistry’s most transformative treatments: a full arch of fixed, natural-looking teeth supported by as few as four dental implants — often placed in a single surgical visit, with temporary teeth the same day.
You may see this treatment called All-on-4, All-on-6, or All-on-X. The names describe the same concept: a complete set of teeth anchored to a small number of strategically angled implants, rather than one implant per tooth. At Expert Dental Group in Roseville, the entire process — 3D CBCT planning, surgery, and the final prosthesis — is handled by Dr. Leila Nikpour, a prosthodontist with 15+ years of specialized experience and 2,500+ dental implants placed.
What is the All-on-X protocol?
The All-on-X protocol replaces a full arch of missing or failing teeth with a fixed bridge on four to six dental implants. The back implants are angled to engage the densest available bone, often eliminating extensive bone grafting. Most patients leave surgery day with temporary teeth and return a few months later for their final, precision-crafted prosthesis.
The “X” simply stands for the number of implants — four, five, or six — determined by your bone anatomy and bite forces. Fewer implants does not mean a weaker result: the angled placement distributes chewing forces across the implants the way engineering distributes load across a bridge’s supports. Because the prosthesis is fixed (not a removable denture), it looks, feels, and functions far more like natural teeth — no slipping, no adhesives, no palate coverage on the upper arch.
Am I a candidate for All-on-4 if I’ve been told I have bone loss?
Quite possibly — yes. Bone loss is the most common reason patients are told they “can’t have implants,” and it is also the situation the All-on-X protocol was specifically designed to address. The angled posterior implants are positioned to take advantage of the bone you still have, frequently avoiding the sinus cavities and nerve areas where bone is thinnest.
When grafting is genuinely needed, it is planned with in-house 3D CBCT imaging, which maps your bone, sinuses, and nerves in high resolution before surgery. This guided approach makes procedures more predictable and less invasive than traditional freehand techniques. At your consultation, Dr. Nikpour will show you your own 3D scan and explain exactly what your anatomy allows — including an honest assessment if your case requires staged grafting before implants can be placed.
Good candidates are generally healthy adults missing most or all teeth in an arch, or facing extraction of remaining failing teeth. Uncontrolled diabetes, active gum disease, heavy smoking, and certain bone medications can affect healing and must be evaluated individually. Your medical history is reviewed carefully before any treatment is recommended.
What is All-on-4 surgery day like?
Surgery day is carefully choreographed to be calm and efficient. Most patients choose IV sedation, so you are comfortable and unaware during the procedure. Remaining failing teeth are removed, the implants are placed using the 3D surgical guide, and a temporary fixed bridge is secured — all in one visit, typically lasting a few hours.
You will not leave without teeth. That is one of the protocol’s defining advantages: you wake up with a full, functional set of temporary teeth. These temporaries are designed for the healing period — slightly softer diet, careful hygiene — while the implants integrate with your bone over the next three to six months. A companion should drive you home, and most patients rest for the remainder of the day.
How long does All-on-4 recovery take?
Most patients return to desk work within three to five days, with most swelling and soreness resolving in the first week to ten days. You’ll follow a soft-food diet during early healing, progressing as comfort allows. The deeper process — osseointegration, where bone fuses to the implants — takes three to six months, with scheduled check-ins along the way.
Here is what honest recovery looks like, week by week: days one through three bring the most swelling, managed with prescribed medication, cold compresses, and rest. By week two, most patients feel substantially normal and are eating a widening range of soft foods. The temporary bridge lets you smile, speak, and socialize throughout. At the three-to-six-month mark, once integration is confirmed, we take final impressions and craft your definitive prosthesis — the permanent, highly aesthetic teeth designed for decades of function.
How long do All-on-X implants last?
The implants themselves — the titanium posts fused to your bone — have excellent long-term track records, with published studies showing survival above 95% at ten years and beyond. The prosthesis (the visible teeth) is different: like any restoration, it experiences wear and may need maintenance or eventual replacement over the years, particularly if you grind your teeth.
Longevity is not luck; it is maintenance. Daily hygiene with the right tools (water flossers and interdental brushes work well under fixed bridges), professional cleanings on schedule, and a night guard if you clench all protect the result. At Expert Dental Group, All-on-X patients are enrolled in a structured maintenance program with periodic imaging, because catching small changes early is what keeps implant treatment successful for decades.
How much does All-on-4 cost in Roseville?
In the Roseville and Sacramento region, full-arch All-on-X treatment typically ranges from roughly $20,000 to $35,000 per arch. The range reflects real variables: the number of implants, whether extractions or grafting are needed, the materials chosen for the final prosthesis (acrylic, nano-ceramic, or zirconia), and the complexity of your bite.
Anyone quoting you an exact figure without a 3D scan and examination is guessing. Schedule a consultation for an exact quote based on your case — you’ll receive a written, itemized plan covering surgery, temporaries, and the final prosthesis, plus a clear discussion of phasing and financing options. Treating one arch now and the second later is common, and we’ll map the full journey so there are no surprises.
All-on-4 vs. traditional dentures: what’s the real difference?
A traditional denture rests on the gums and is removable; an All-on-X bridge is fixed to implants. Fixed teeth don’t slip during speech or meals, restore far more chewing force, and stimulate the jawbone — slowing the bone loss that continues under dentures. Upper All-on-X bridges also leave the palate uncovered, so taste and temperature sensation feel normal.
Dentures remain a valid, lower-cost option, and for some patients they are the right choice. But patients who have lived with both consistently describe the fixed implant bridge as the closer return to natural teeth. If you’ve been tolerating a denture that moves, sore spots, or a diet of soft foods, a consultation can show you — on your own 3D scan — whether All-on-X is possible for you.
Frequently asked questions about All-on-4 dental implants
Will I be without teeth at any point?
No. One of the defining features of the All-on-X protocol is that you receive a fixed set of temporary teeth on the day of surgery. You leave the appointment with a complete smile and never go through a toothless healing period.
Is All-on-4 surgery painful?
Surgery itself is performed under sedation or anesthesia, so you feel nothing during the procedure. Post-operative discomfort is typically managed with prescribed medication for the first few days; most patients describe it as less difficult than they expected, with swelling peaking around day two or three and then steadily improving.
Can All-on-4 be done if I currently wear dentures?
Yes — denture wearers are among the most common All-on-4 patients, and many say they wish they’d done it sooner. Long-term denture wear does cause bone shrinkage, which is why the 3D CBCT evaluation is essential: it shows exactly how much bone remains and whether the standard protocol or a grafting-first approach is right for you.
What are the temporary teeth made of, and what can I eat?
Temporary bridges are typically crafted from high-quality acrylic designed for the healing months. You’ll eat soft foods initially — eggs, fish, pasta, cooked vegetables, smoothies — and progress as healing allows. Your final prosthesis, in stronger materials, restores a much broader diet.
How do I clean fixed All-on-X teeth?
Daily cleaning uses a soft brush, a water flosser, and interdental brushes or floss threaders to clean beneath the bridge where it meets the gums. We’ll demonstrate the technique and check your home care at every maintenance visit. Professional cleanings with implant-safe instruments are scheduled regularly.
What if one implant fails?
Implant failure is uncommon, but the protocol accounts for it: treatment is planned so the prosthesis remains supportable, and a failed implant can typically be replaced after healing. This is one reason periodic imaging and maintenance visits matter — they catch problems while they’re small and solvable.
Is there an age limit for All-on-4?
There is no upper age limit — jawbone can integrate implants successfully well into the 80s and beyond, provided overall health allows surgery. What matters is your medical fitness for the procedure, bone quality, and commitment to maintenance, all of which are assessed at your consultation.
