All-on-4 in Fairfield, CA is one of the most searched dental procedures in our area — and for good reason. If you’re missing most or all of your teeth and want a permanent fixed solution that works like natural teeth, full arch implants are the most life-changing treatment modern dentistry offers. But when you start researching, you run into two terms — All-on-4 and All-on-X — and it’s not always clear what the difference is or which one you actually need.
At Fairfield Dentistry & Implants on Oliver Rd in Fairfield, CA 94534, Dr. Singh has completed over 1,500 implant cases including both procedures. This guide explains exactly what each option involves, how they differ, who is a candidate for each, and what patients in Fairfield should know before booking a consultation.
What Is All-on-4 in Fairfield, CA?
All-on-4 in Fairfield, CA is a full arch tooth replacement procedure where a complete set of fixed teeth — upper or lower — is anchored to exactly four dental implants. Two implants are placed vertically at the front of the jaw, and two are placed at an angle toward the back. That angled placement is the defining characteristic of All-on-4 — it maximizes contact with available bone and often eliminates the need for bone grafting even in patients who have experienced significant bone loss.
The result is a full arch of fixed teeth that are attached to the implants and do not come out. You do not remove them at night. They function, look, and feel like natural teeth.
The All-on-4 concept was developed and trademarked by Nobel Biocare. The technique uses exactly four implants per arch, and the prosthesis is designed specifically for that four-implant configuration.
What Is All-on-X in Fairfield, CA?
All-on-X is the broader term for full arch implant restoration using a variable number of implants — typically four, five, or six depending on what the patient’s bone structure, bite forces, and anatomy require. The “X” simply means the number of implants is not fixed — it’s determined by what gives the best outcome for that specific patient.
In practice, All-on-X procedures at our Fairfield practice most commonly use four to six implants per arch. Patients with higher bite forces, better bone density, or specific anatomical needs may benefit from five or six implants for additional stability and long-term durability.
All-on-X is not a brand name — it is a descriptive term used by implant surgeons to distinguish customized full arch protocols from the rigid four-implant Nobel Biocare system.
All-on-4 vs All-on-X in Fairfield, CA — The Key Differences
The honest answer is that for many patients, the distinction is less important than finding a skilled surgeon who will properly evaluate your bone structure and design the right treatment for you. That said, here is how they compare:
Number of implants — All-on-4 uses exactly four. All-on-X uses four, five, or six based on individual assessment.
Bone requirements — All-on-4 was specifically designed to work with limited bone, using angled implants to avoid the sinus and nerve areas where bone is often insufficient. All-on-X may use additional implants to compensate for bone deficiencies differently, or may require bone grafting in some cases.
Prosthesis design — All-on-4 prostheses are engineered for four attachment points. All-on-X prostheses can be designed around more implants, which some surgeons argue distributes bite forces more evenly over time.
Cost — All-on-4 with four implants is generally the entry point for full arch restoration. Adding implants in an All-on-X protocol adds to the cost but may provide better long-term outcomes for specific patients. At Fairfield Dentistry & Implants, full arch restoration starts at $14,999 per arch.
Long-term durability — Both approaches produce excellent outcomes when cases are properly selected and the surgery is well executed. The implant number matters less than bone quality, surgical precision, and how well the patient maintains the restoration.
Who Is a Candidate for Full Arch Implants in Fairfield, CA?
All-on-4 in Fairfield, CA and All-on-X procedures are appropriate for patients who:
- Are missing all or most teeth on one or both arches
- Have failing teeth that need to be extracted
- Wear full dentures and want a permanent fixed alternative
- Have been told they don’t have enough bone for traditional implants
- Are in good general health and do not have uncontrolled systemic conditions
Patients who have been told they cannot get implants due to bone loss are often still candidates for All-on-4 specifically because of the angled implant placement technique. The only way to know for certain is a 3D CT scan that maps your bone volume precisely. Dr. Singh reviews this imaging at every consultation before making any recommendations.
Patients in Fairfield, Suisun City, Vacaville, Cordelia, and Travis AFB come to us specifically because we do not tell patients they are not candidates without first completing a full 3D imaging assessment.
The All-on-4 and All-on-X Procedure at Our Fairfield Practice
For most patients, here is what the process looks like from consultation to final teeth:
Consultation and 3D CT scan — Dr. Singh reviews your bone density, volume, nerve positions, and sinus anatomy using cone beam CT imaging. This determines whether All-on-4 or a higher implant count is appropriate, and whether any bone grafting is needed beforehand.
Treatment planning — You receive a complete written treatment plan with all costs before committing to anything. No surprise fees.
Extraction and implant placement — Failing or remaining teeth are extracted and implants are placed in the same surgical appointment in most cases. Many patients leave this appointment with temporary fixed teeth the same day — this is commonly called teeth-in-a-day.
Healing period — Implants integrate with the jawbone over three to six months. During this period you wear a temporary prosthesis that is functional but not the final restoration.
Final prosthesis — Once osseointegration is confirmed, the final custom arch is fabricated and attached. This is the permanent set of teeth you will have for decades.
For patients who need urgent care due to dental pain or failing teeth, our emergency dental implant team at Emergency Dentist Fairfield can see same-day patients and begin the evaluation process immediately.
All-on-4 vs Dentures — Why Patients in Fairfield Make the Switch
Many patients who come to us for All-on-4 in Fairfield, CA have been wearing dentures for years. The difference in quality of life is dramatic and it is worth understanding why.
Traditional dentures sit on top of the gums and rely on suction or adhesive to stay in place. They move when you eat, limit what foods you can enjoy, and accelerate bone loss in the jaw because they do not stimulate the bone the way natural tooth roots do. Over time, the face changes shape as bone volume decreases — this is the sunken facial appearance that many long-term denture wearers develop.
All-on-4 implants are anchored directly in the bone. They stimulate bone the way natural roots do, preserving jaw structure. The teeth do not move. You can eat anything. You brush them like natural teeth. Most patients describe the change as getting their life back.
The upfront cost is higher than dentures, but implants do not need to be replaced every five to seven years the way dentures do. Over a lifetime, they are the more cost-effective option for most patients.

Frequently Asked Questions About All-on-4 in Fairfield, CA
What is the difference between All-on-4 and All-on-X in Fairfield, CA?
All-on-4 uses exactly four implants per arch using the Nobel Biocare protocol with two angled rear implants. All-on-X uses four, five, or six implants depending on the patient’s bone structure and bite requirements. Both produce a full fixed arch of permanent teeth. The right choice depends on your individual anatomy, which is determined by 3D CT imaging.
How much does All-on-4 cost in Fairfield, CA?
Full arch restoration at Fairfield Dentistry & Implants starts at $14,999 per arch. The final cost depends on whether extractions are needed, whether bone grafting is required, and how many implants are placed. We provide a complete written cost breakdown before any treatment begins.
Can I get All-on-4 if I have bone loss in Fairfield, CA?
Often yes. All-on-4 was specifically designed for patients with bone loss, using angled implants to access denser bone toward the front of the jaw. The only way to confirm candidacy is a 3D CT scan. Many patients told elsewhere that they don’t qualify are found to be good candidates after proper imaging.
How long does All-on-4 last in Fairfield, CA?
With proper care, the implant posts can last a lifetime. The prosthetic arch typically lasts 15–20 years before it may need replacement due to normal wear. The bone-stimulating effect of the implants preserves jaw structure long-term — something no denture can do.
Is the All-on-4 procedure painful?
The surgery is performed under local anesthesia and sedation options are available. Most patients report that the procedure itself is far less uncomfortable than they anticipated. Post-surgical soreness is manageable with prescribed medication and typically resolves within a few days to a week.
How soon can I eat normally after All-on-4 in Fairfield, CA?
You leave with temporary fixed teeth the same day in most cases. During the healing period — typically three to six months — a soft diet is recommended to protect the integrating implants. Once the final prosthesis is placed, you can eat a full normal diet including hard and crunchy foods.
