If you’re in Citrus Heights and most of the teeth in an arch are failing — or you’re already wearing a full denture — you’ve probably encountered a confusing menu: All-on-4, All-on-6, snap-on dentures, implant bridges. They all use dental implants, but they differ in meaningful ways. This guide compares them side by side so you can walk into a consultation knowing what to ask.
What Counts as “Full-Arch”?
A full arch is all the teeth in your upper or lower jaw. Full-arch restoration replaces every tooth in that arch with prosthetic teeth anchored to implants — typically four to six per arch. The key word is fixed: unlike a conventional denture, these teeth don’t come out, don’t shift when you eat, and don’t cover the roof of your mouth. It makes sense when saving individual teeth is no longer practical — advanced gum disease, widespread decay or fractures, repeated crown failures, or a denture you’re tired of fighting.
Option 1: All-on-4 — Fixed Teeth on Four Implants
The most widely used full-arch approach. Four implants per arch — the rear two angled to engage available bone — support a complete fixed set of teeth. Strengths: the angled design frequently avoids bone grafting even with significant bone loss, and temporary fixed teeth are often attached the same day as surgery. Trade-offs: four implants carry the full chewing load, so the prosthesis and bite must be engineered carefully. Best for: patients wanting fixed teeth with minimal surgery and grafting.

Option 2: All-on-6 — Six Implants for Broader Support
Same concept, with two additional implants distributing forces across more anchor points. Strengths: broader load distribution — more margin for strong bite forces and long-term durability. Trade-offs: requires sufficient bone in six positions, sometimes meaning grafting where All-on-4 would have avoided it; slightly more surgical time and investment. Best for: patients with adequate bone who want maximum support, including heavy grinders.
Option 3: Implant-Supported Overdenture — The Snap-On Denture
A full denture clipping onto two to four implants. Strengths: dramatically more stable than a conventional denture — no slipping, no adhesive — at the lowest investment of any implant full-arch option, with straightforward removable hygiene. Trade-offs: bulkier than fixed teeth, less chewing power, and attachments wear and need periodic replacement. Best for: patients prioritizing economy and easy cleaning.
Option 4: Conventional Full Denture (for Comparison)
The baseline many patients compare against. Strengths: lowest upfront investment, no surgery. Trade-offs: ongoing bone loss continues underneath, fit loosens over time requiring relines and replacements, chewing power is a fraction of natural teeth, and upper dentures cover the palate, dulling taste. Best for: patients who cannot undergo implant surgery medically, or as an interim solution.
Side-by-Side Comparison
| | All-on-4 | All-on-6 | Snap-on denture | Conventional denture | |—|—|—|—|—| | Fixed or removable | Fixed | Fixed | Removable | Removable | | Typical implants per arch | 4 | 6 | 2–4 | 0 | | Chewing power | High | Highest | Moderate | Low | | Bone preservation | Yes | Yes | Partial | No | | Grafting often needed? | Less often | Sometimes | Rarely | N/A | | Relative investment | Higher | Highest | Moderate | Lowest |
General patterns — your bone, bite, and health determine which options are actually available to you.
How a Prosthodontist Matches the Option to the Patient
This matching decision is where specialist training earns its keep. A prosthodontist evaluates bone volume and density (from 3D CBCT imaging), bite forces and jaw relationship, gum health, esthetic goals, and budget — then recommends the option your anatomy supports and your priorities favor.
Dr. Leila Nikpour is a prosthodontist with more than 15 years of dentistry experience, 2,500+ dental implants placed, and a one-year implantology fellowship in France. At Expert Dental Group, full-arch cases are planned on in-house 3D imaging — implant positions, angles, and the final tooth design verified digitally before surgery. Read more about Dr. Nikpour.
The Timeline
Consultation, 3D scan, and written plan → preparatory work (extractions/grafting if needed) → implant surgery, often with temporary teeth the same day → 3–6 months of healing with check visits → final prosthesis → ongoing maintenance. Most cases run 6–12 months from first visit to final teeth.
Cost Factors — An Honest Breakdown
Number of implants and chosen option, materials and craftsmanship of the final prosthesis, bone grafting if needed, extractions, and one arch or both. Beware advertised prices covering only the surgery or only the temporaries — a meaningful quote includes everything through the final prosthesis. At a free consultation, you’ll receive exactly that: a complete written plan with transparent, all-inclusive pricing and no obligation.
Frequently Asked Questions
Which full-arch option lasts the longest?
The implants can last decades in all implant options with proper care. Fixed prostheses generally outlast removable ones before needing refurbishment. Maintenance habits matter as much as the option chosen.
Can I switch from a snap-on denture to fixed teeth later?
Often, yes — existing implants can sometimes support a fixed prosthesis later, though additional implants may be needed. Worth discussing during planning if your budget or preferences might change.
Will people know my teeth aren’t real?
Modern full-arch prostheses are designed around your facial features, age, and preferences. Designed by a prosthodontist with esthetic training, the result looks like natural teeth, not “dental work.”
What if I grind my teeth?
Grinding doesn’t rule out full-arch implants, but it changes the engineering — possibly favoring All-on-6, a protective night guard, or specific materials. Mention it at your consultation; it’s a routine planning input.
How do I clean fixed full-arch teeth?
Daily cleaning with a water flosser, interdental brushes, and brushing — plus professional visits where the dentist removes the prosthesis for thorough cleaning. Most patients master the routine within weeks.
Is the drive from Citrus Heights to Roseville practical for this?
Full-arch treatment is a series of visits spread over 6–12 months. Citrus Heights patients make the short drive routinely because 3D planning, specialist experience, and single-office imaging consolidate care that would otherwise mean multiple referrals.
