All-on-X Full-Arch Dental Implants in Woodland Hills
A complete, fixed arch of teeth — anchored permanently to 6 or more implants, never fewer. Built stronger. Designed to last.
What Is All-on-X?
All-on-X is a full-arch dental implant solution that replaces an entire row of missing or failing teeth with a single fixed prosthetic arch, anchored directly to implants placed in the jawbone. The “X” refers to the number of implants used to support that arch — and at First Dental Implant Center, that number is never fewer than 6.
The result is a complete set of teeth that does not come out, does not require adhesive, and is designed to function like natural teeth — for chewing, speaking, and smiling with confidence.
The Stunning System — Dr. Kass Nourishad’s All-on-6 Protocol
Dr. Kass Nourishad developed the Stunning System after observing a pattern across the implant industry: many providers default to placing the fewest implants possible per arch to reduce cost and chair time. First Dental Implant Center takes the opposite approach.
The Stunning System is a full-arch protocol built on a minimum of 6 implants per arch — delivered at no extra charge. More implants distribute bite force more evenly, reduce the load placed on any single implant, and create a more stable long-term foundation. This is not an upsell. It is the standard of care Dr. Kass has built his practice around for more than 20 years.
Why 6 or More, and Never Fewer
Picture a table. A table built on four legs is functional, but the moment one leg weakens or fails, the entire structure becomes unstable. A table built on six points of support distributes weight more evenly and tolerates the loss of a single point of support far better.
The same principle applies to a full dental arch under constant biting force. Fewer implants means each one carries more load, and failure of a single implant has a greater impact on the entire restoration. Six or more implants spread that load across more points of support — which is the foundation of why the Stunning System is built the way it is.
The Engineering Behind the Number
The load a full arch absorbs is not trivial. The human bite generates substantial force at the molars — enough that every fixture supporting the arch is under real, repeated stress with each chew, every day, for the life of the restoration. How that force is managed is an engineering problem, not a cosmetic one.
When an arch is supported by too few implants, each fixture absorbs a larger share of that force, and the unsupported spans between implants — the cantilevers — grow longer. Longer cantilevers act as levers, multiplying stress on the implants nearest the load. Over years, that concentrated stress is what contributes to loosening, bone loss around the implant, and eventual failure.
Adding implants changes the math. More fixtures mean shorter spans, smaller cantilevers, and force distributed across more points of anchorage — reducing the peak stress any single implant ever has to carry. Combined with deliberate implant angulation and cross-arch stabilization (the way the implants brace one another across the full curve of the jaw), the result is a foundation engineered to minimize micro-movement and long-term stress rather than simply hold teeth in place on the day of surgery.
This is why the Stunning System begins at six. Six is the floor, not the target — and for many patients, the engineering calls for more.
Six or More: Engineered to Your Case
Six implants per arch is our minimum, never our default answer to every patient. The right number for your restoration depends on the anatomy Dr. Kass evaluates before treatment: the length and shape of the arch, the density and volume of available bone, the position of anatomical structures, and the force your bite actually generates. Where the case calls for it, Dr. Kass places seven, eight, or more.
That decision is made during planning — deliberately, based on your imaging — not on the day of surgery and never to fit a fixed price or protocol. A one-size-fits-all implant count is exactly what the Stunning System was built to avoid. The number is engineered up from six until the foundation is right for you.
Why First Dental Implant Center Does Not Use Fewer-Implant Systems
Some full-arch systems on the market — including systems that rely on as few as four implants per arch — are marketed heavily for their speed and lower upfront cost. First Dental Implant Center does not offer or recommend these reduced-implant approaches.
A four-implant system places more functional demand on each individual implant. If one of those four implants fails or loosens over time, the entire arch is compromised — there are fewer remaining points of support to redistribute the load. Dr. Kass’s clinical philosophy, reflected in the Stunning System, is that a stronger foundation built on 6 or more implants reduces this risk and is more likely to deliver a result that lasts for decades, not years.
This is why every All-on-X case at First Dental Implant Center begins at 6 implants per arch — regardless of system name, cost-cutting trend, or industry default.
The Foundation Is Designed Before a Single Incision
The strength of a full-arch restoration is determined long before surgery — in the planning. Every Stunning System case is engineered on the screen first: Dr. Kass uses 3D cone beam CT imaging to map bone volume, density, and the exact position of nerves and sinuses, then plans the number, position, angle, and depth of every implant against that anatomy. Surgical guides built from that plan carry it precisely into the procedure, so placement matches design rather than improvisation.
This is where the implant count is decided, where cantilevers are minimized, and where load distribution is solved as an engineering question — before any surgery begins. It is the difference between placing implants and building a foundation.
Designed for Your Face — Not a Machine-Produced Template
Many full-arch providers — including national chains — rely on CAD/CAM systems that produce standardized prosthetics from a limited set of templates. The result can look noticeably artificial: too uniform, too symmetrical, disconnected from the patient’s actual facial structure.
Dr. Kass takes a different approach. Every Stunning System case begins with an individualized analysis of the patient’s facial structure, age, and gender — the same variables that shape how a natural smile looks and ages over time. The goal is a result that looks like it belongs to you, not a result that looks like it came from a catalog.
This personalization is supported by the same 3D imaging and digital impressions used to plan your restoration, detailed further on our Technology page — ensuring the final smile is designed around your face, not a template.
Who Is a Candidate for All-on-X?
All-on-X is designed for patients who have lost most or all of their teeth in an arch, or who have teeth that cannot be saved due to decay, periodontal disease, or trauma. It is also a common solution for patients currently wearing dentures who want a fixed, permanent alternative.
Candidacy depends primarily on the volume and quality of available jawbone. Patients with significant bone loss may still be candidates after bone grafting and ridge augmentation — a service Dr. Kass performs directly, without referral to an outside specialist.
- Most or all teeth missing or failing in one or both arches
- Currently wearing removable dentures and seeking a fixed alternative
- Been told by another provider that you are not a candidate (bone grafting may change that answer)
- Seeking a long-term, permanent solution rather than a removable one

Validated Expertise — Not a Marketing Claim
Dr. Kass Nourishad’s credentials are not self-declared. His status as a Diplomate of the International Congress of Oral Implantologists (ICOI) is earned through a documented case history, peer review, and demonstrated surgical and restorative competency — a process that requires submitting 500 documented implant cases for evaluation. It is the highest level of recognition in the field of oral implantology, and it is held by a small fraction of practicing implant dentists.
Dr. Kass is also a Fellow of the American College of Oral Implantology and has an extensive publication history in implant dentistry. He has been performing full-arch implant reconstruction for more than 20 years and, in 1989, established the first dedicated implant center in Santa Barbara County — making him the first oral health professional in California to open an implant-exclusive practice, a founding history that predates the national implant chains operating in Southern California today.

What to Expect
Step 1 — Consultation & 3D Imaging
Dr. Kass evaluates your bone structure, health history, and goals using cone beam CT imaging and digital impressions. You leave knowing exactly what your treatment involves, whether you qualify for same-day delivery, and what it will cost.
Step 2 — Custom Treatment Planning
Every case is planned individually. Dr. Kass analyzes your facial structure, age, and gender to design a smile that looks natural on you — not a template produced by a machine. Implant number, placement, and angle are mapped before surgery.
Step 3 — Implant Placement
Using surgical guides developed from your 3D imaging, Dr. Kass places 6 or more implants with precision. For qualifying same-day cases, your fixed temporary arch is delivered the same day as placement — see our Teeth in One Day page for details.
Step 4 — Healing & Integration
Implants integrate with the jawbone over a period of months. Dr. Kass monitors healing through follow-up visits and digital imaging to confirm the foundation is stable before final restoration.
Step 5 — Final Restoration
Once integration is complete, your permanent prosthetic arch is placed. The result is a fixed, non-removable smile that functions and feels like natural teeth — built stronger, designed to last.
Built to Hold — Not Just to Fit
A foundation built on more points of support has a structural advantage that lasts: even in the rare event that a single implant develops an issue years down the line, the surrounding fixtures continue to carry the arch — where a reduced-implant system has far less margin to absorb that loss. Combined with even force distribution that reduces long-term stress on bone, and the healing verification Dr. Kass confirms through imaging before final restoration, the result is a foundation designed for durability measured in decades.
Why Some Full-Arch Implants Fail — and How the Stunning System Is Built to Avoid It
Patients researching full-arch implants are often doing so after a difficult experience — a failed restoration, a bad outcome elsewhere, or fear of a future failure. It is worth addressing honestly.
Full-arch implants most commonly fail for a small number of reasons: insufficient bone volume at the time of placement, implant material that does not integrate reliably with bone, restorations that distribute bite force unevenly across too few implants, and inadequate pre-surgical planning that misjudges anatomy.
The Stunning System addresses each of these directly. Bone volume is assessed and, where needed, rebuilt through grafting before placement. Implants are USA-made, not sourced overseas. Six or more implants distribute load more evenly than fewer-implant systems. And every case is planned using 3D cone beam CT imaging before a single incision is made — removing the guesswork that leads to surgical surprises.
What Our Patients Are Saying
"Dr. Kass is a master of that craft. The results on my teeth are beyond anything I could have imagined. I was nervous going in, but the entire experience was straightforward. Fast, precise, and the outcome changed my life."
"Two other specialists told me I wasn't a candidate. Dr. Kass listened, looked at the imaging himself, and built a plan. I have a fixed smile today because of him."
"I drive 2.5 hours to see Dr. Kass. There is no one closer I would trust with this."
Real Results
Every case in our gallery is a patient who came to us with failing teeth, damaged bone, or full tooth loss — and left with a permanent, fixed result.
Investing in a Permanent Solution
First Dental Implant Center accepts most major PPO dental insurance plans and offers 0% financing on approved credit through CareCredit, Cherry, and Lending Club. Full-arch cases qualify for extended payment terms — cost should never be the reason a permanent solution stays out of reach.

What does “All-on-X” mean?
All-on-X refers to a full-arch dental implant restoration where “X” represents the number of implants supporting the arch. At First Dental Implant Center, every All-on-X case uses a minimum of 6 implants per arch — the foundation of Dr. Kass Nourishad’s Stunning System.
How many implants does First Dental Implant Center use for a full arch?
Dr. Kass Nourishad uses a minimum of 6 implants per arch for every full-arch case, at no extra charge. This is more than many providers use by default, and it is a deliberate choice to provide a stronger, more stable foundation for long-term results.
Why does First Dental Implant Center use 6 implants instead of 4?
Six or more implants distribute bite force across more points of support than a four-implant system. If one implant in a four-implant arch experiences a problem, the remaining three must absorb significantly more load. A six-implant foundation tolerates that kind of stress far better, which supports longer-lasting results.
Does every patient receive exactly six implants?
Six per arch is our minimum — never fewer. But it isn't an automatic answer for every case. Depending on your bone volume, arch shape, and bite force, Dr. Kass may plan for seven, eight, or more implants to build the strongest foundation for your specific anatomy. The number is determined during planning, from your 3D imaging, and is always engineered up from six rather than cut down to a price.
Can I get a fixed arch of teeth in one day?
Many patients qualify for same-day delivery of a fixed temporary arch following implant placement, depending on bone volume and overall health. Dr. Kass will evaluate your candidacy for same-day treatment during your consultation. Visit our Teeth in One Day page for details.
What if I've been told I'm not a candidate for implants due to bone loss?
Bone loss is one of the most common reasons patients are told they don't qualify for implants elsewhere. Dr. Kass performs bone grafting and ridge augmentation directly, which can restore the bone volume needed for successful implant placement. A consultation can determine whether this applies to your case.
What makes the Stunning System different from other full-arch systems?
The Stunning System is Dr. Kass Nourishad’s proprietary All-on-6 protocol, built on individualized facial analysis, 3D cone beam CT imaging, and a minimum of 6 implants per arch. Unlike machine-produced, standardized prosthetics, every Stunning System case is designed around the patient’s specific facial structure, age, and gender.
Are the implants used at First Dental Implant Center made in the USA?
Yes. First Dental Implant Center exclusively uses USA-manufactured implants — never materials sourced overseas to reduce cost. This is a deliberate quality standard, not a default.
