If you are missing most or all of the teeth in an upper or lower arch, full-arch dental implants in Sacramento can give you back a complete, functional smile. But you will quickly encounter three main options — All-on-4, All-on-6, and implant-supported overdentures — and they are genuinely different treatments.
This guide compares them honestly: how they work, who each suits best, and what to consider when choosing.
What “Full-Arch” Means
“Full-arch” simply means replacing all the teeth in one jaw (upper or lower) — typically 10 to 14 teeth — supported by dental implants instead of resting on the gums like a traditional denture. All three options below are full-arch solutions; they differ in the number of implants, whether the teeth are fixed or removable, and how they feel day to day.
Option 1: All-on-4 Dental Implants
All-on-4 uses four strategically placed implants to support a full arch of fixed (non-removable) teeth. The two back implants are tilted to maximize contact with available bone, which often means bone grafting can be avoided.
- How many implants: 4 per arch
- Fixed or removable: Fixed — only your dentist removes it
- Feel and function: Feels closest to natural teeth; strong, stable chewing
- Best for: Patients who want a permanent, fixed solution and have adequate bone (or want to avoid grafting); often completed with temporary teeth the same day (“teeth in a day”)
- Maintenance: Brush and floss like natural teeth, plus professional cleanings; the prosthesis is occasionally removed by your dentist for deep cleaning
Option 2: All-on-6 Dental Implants
All-on-6 follows the same concept but uses six implants per arch, distributing bite forces across more anchor points.
- How many implants: 6 per arch
- Fixed or removable: Fixed — only your dentist removes it
- Feel and function: Maximum stability and support; excellent for strong bite forces
- Best for: Patients with good bone volume who want the most robust long-term support, or those replacing an arch where extra stability is beneficial
- Maintenance: Same home care as All-on-4; more implants can mean slightly more involved hygiene around the additional posts
The trade-off versus All-on-4: more implants generally mean more support, but also a more involved surgery and a higher overall investment. Neither is universally “better” — the right choice depends on your bone, your bite, and your goals.
Option 3: Implant-Supported Overdentures
An overdenture is a full denture that snaps onto 2 to 4 implants via attachments. Unlike a traditional denture, it does not rely on suction or adhesive — the implants lock it firmly in place.
- How many implants: Typically 2 to 4 per arch
- Fixed or removable: Removable — you take it out nightly for cleaning
- Feel and function: Far more stable than a conventional denture; dramatically better chewing than adhesive-held dentures, though not quite the feel of fixed teeth
- Best for: Patients who want major improvement over traditional dentures at a more accessible investment, or who prefer a removable appliance for easier cleaning
- Maintenance: Remove and clean daily; attachments (the snap components) wear over time and need periodic replacement
Side-by-Side Comparison
- Number of implants: Overdenture 2–4 < All-on-4 (4) < All-on-6 (6)
- Fixed vs. removable: All-on-4 and All-on-6 are fixed; overdentures are removable
- Chewing confidence: All three far exceed traditional dentures; fixed options feel most like natural teeth
- Bone requirements: Overdentures need the least; All-on-4’s tilted implants often avoid grafting; All-on-6 typically needs the most bone volume
- Daily maintenance: Overdentures are easiest to clean (removed nightly); fixed options need diligent brushing, flossing aids, and water flossers
- Long-term upkeep: Overdenture attachments need periodic replacement; fixed prostheses occasionally need professional removal and servicing
- Overall investment: Generally overdentures < All-on-4 < All-on-6, though your specific case determines the actual plan
Why a Prosthodontist Plans Full-Arch Cases
Full-arch implant treatment is among the most complex procedures in dentistry. It requires planning the implant positions, the bite, the esthetics, and the long-term maintenance as one integrated system — which is precisely what prosthodontists are trained to do.
Dr. Leila Nikpour, a prosthodontist serving the Sacramento area from Roseville, brings more than 15 years of dentistry experience, a one-year implantology fellowship in France, and 2,500+ dental implants placed to every full-arch case. Each case is planned with in-house 3D CBCT imaging, so implant angles, bone volume, and nerve positions are mapped before treatment begins — critical for approaches like All-on-4, where tilted implant placement must be exact.
How to Choose the Right Option
Ask yourself — and discuss with your prosthodontist:
- Do I want teeth that never come out, or am I comfortable removing an appliance nightly?
- What does my 3D scan show about my bone volume?
- How strong is my bite, and do I grind my teeth?
- What level of long-term maintenance am I prepared for?
- What does my budget allow, and what financing options exist?
There is no universal winner. The best full-arch solution is the one matched to your anatomy, your lifestyle, and your goals.

Frequently Asked Questions
Which is better: All-on-4 or All-on-6?
Neither is universally better. All-on-6 distributes forces across more implants, while All-on-4’s tilted placement often avoids bone grafting. The right choice depends on your bone volume, bite forces, and goals — a 3D-planned evaluation decides.
Are implant overdentures removable?
Yes. An implant-supported overdenture snaps onto 2–4 implants for stability but is removed nightly for cleaning. It is far more stable than a traditional denture but does not feel as fixed as All-on-4 or All-on-6.
Can I eat normally with full-arch implants?
Fixed full-arch options (All-on-4, All-on-6) restore strong chewing function close to natural teeth. Overdentures are a major improvement over conventional dentures. Your prosthodontist will set realistic expectations for your case.
How long do full-arch implants last?
The implants themselves can last decades with proper care. The prosthetic teeth may eventually need repair or replacement after many years of use. Regular checkups and good hygiene are essential.
What does full-arch treatment cost?
Cost varies with the number of implants, whether grafting is needed, and the type of final prosthesis. Schedule a consultation for an exact, personalized treatment plan and transparent pricing.
