If you are missing most or all of your teeth on one arch, you have likely been weighing two options: replace each tooth individually, or restore the entire arch at once with All-on-4. For patients who want a permanent, natural-looking result without years of staged procedures, the difference between these approaches is worth understanding clearly — more clearly than any brochure tends to explain.
This article covers how All-on-4 works, how it stacks up against individual implants on cost, timeline, and candidacy, and what to expect when you sit down with a board-certified periodontist for a real evaluation.
01
What All-on-4 Actually Is
All-on-4 is a full-arch restoration technique. Rather than placing one implant per missing tooth, a periodontist places four strategically angled titanium implants into the jawbone and attaches a complete arch of prosthetic teeth to those four anchors — typically in a single appointment.
The name is straightforward: four implants, one arch, one day.
The two rear implants are angled at roughly 45 degrees, which lets them reach denser bone farther back in the jaw without requiring bone grafting in many patients. That angulation is what makes the single-day timeline possible for candidates who would otherwise spend months on bone-building procedures first.
02
How All-on-4 Compares to Individual Implants
Both approaches use titanium implants that fuse with the jawbone. The differences come down to quantity, staging, cost structure, and who qualifies.
Number of Implants and Surgical Appointments
Individual implants replace teeth one at a time. A full upper or lower arch typically requires eight to ten implants — sometimes more — placed across multiple appointments. Bone grafting is often needed at individual sites before placement can happen, which adds months to the process.
All-on-4 uses four implants per arch. Because the rear implants are angled to work with the bone that is already there, many patients avoid grafting entirely. The result is a complete arch supported by four anchors instead of eight or more.
Cost Structure
Individual implants are priced per tooth or per implant position. When you are replacing a full arch, those per-position costs add up fast.
All-on-4 spreads the cost of a full arch across four implants rather than eight to ten. On a per-position basis, that can work out to roughly half the cost of restoring the same arch individually — though the actual difference depends on your bone anatomy, the prosthetic selected, and what preparatory work your case requires. No honest provider will give you a fixed number before reviewing your imaging.
What you should expect from any reputable periodontist is a written, itemized treatment plan before you agree to anything. At Sterling Periodontics & Implantology, every patient receives exactly that — a take-home written plan after the initial evaluation, so you can review the numbers, ask questions, and decide without pressure.
Timeline
Individual implants follow a staged process. Each implant needs three to six months to osseointegrate — to fuse with the bone — before a crown can be attached. When multiple implants are placed at different times, the full restoration can stretch to a year or more.
All-on-4 compresses that timeline considerably. The four implants are placed in one surgical appointment, and a provisional arch is typically attached the same day. The final prosthetic follows after osseointegration, but you leave the office with functional teeth.
Who Qualifies
Individual implants require adequate bone volume at each replacement site. Patients with significant bone loss often need grafting before placement, which extends both the timeline and the cost.
All-on-4 was designed specifically for patients with bone loss. The angled rear implants reach areas of denser bone that remain even after years of tooth loss — which makes All-on-4 a realistic option for patients who were previously told they were not implant candidates.
That said, not everyone qualifies for All-on-4 either. Active, uncontrolled gum disease, certain systemic health conditions, and severe bone loss in specific locations can all affect candidacy. A thorough evaluation with 3D cone-beam imaging is the only way to know where you stand.

Why This Conversation Often Starts at 50+
Adults in their 50s, 60s, and beyond are the most common candidates for full-arch restoration, and for understandable reasons. Decades of dental disease, tooth loss, or failing bridgework accumulate. Dentures that once fit well become loose as the jawbone resorbs over time. And many patients in this group have spent years being told implants were not an option for them.
The anxiety around surgery is real. So is the concern about cost, especially when insurance coverage for implants is limited or unclear. And after years of being steered toward treatments that did not hold, there is reasonable skepticism about being oversold again.
Those concerns deserve a straight answer.
On surgery: All-on-4 is performed under local anesthesia, with sedation options available. It is more involved than a single extraction. Most patients describe the recovery as manageable, though individual experience varies.
On cost and financing: Sterling Periodontics accepts insurance and offers 0% financing for qualified patients. Before treatment begins, the practice will walk you through what your plan covers so there are no surprises.
On being oversold: The written take-home treatment plan is a meaningful safeguard. You get the full picture of what is recommended and why — in writing — before any decision is made.

When Individual Implants Make More Sense
All-on-4 is not always the right answer. If you are missing only a few teeth and the remaining ones are healthy and stable, individual implants preserve more of your natural dentition and may be the better long-term choice.
Individual implants also allow for more targeted treatment. If bone loss is limited to one area, a single implant or a small implant-supported bridge can address that area without treating the entire arch.
The right approach depends on how many teeth are missing, the condition of what remains, bone volume across the arch, and what you are hoping to achieve. A periodontist who has reviewed your imaging can walk you through which option fits your anatomy.
05
What a Consultation with a Periodontal Specialist Looks Like
Not every dental office offering All-on-4 has the same level of training. Periodontists are specialists who complete two to three years of post-doctoral training focused on the supporting structures of teeth — bone, gum tissue, and the surgical anatomy that determines implant outcomes. A Diplomate of the American Board of Periodontology, like Dr. Mohamed Khaled at Sterling Periodontics & Implantology, has completed a rigorous credentialing process on top of that specialty training.
For a procedure as significant as full-arch restoration, that distinction is directly relevant. The angulation of implants, the management of remaining gum tissue, and the assessment of bone quality all require a level of expertise that goes beyond general implant placement.
At Sterling Periodontics, the consultation includes a thorough clinical evaluation, 3D imaging where indicated, and a written treatment plan you take home. Same-day and urgent appointments are held weekly for patients who want to move forward without a long wait.

Frequently Asked Questions
How long does the All-on-4 procedure take?
The surgical placement of the four implants and attachment of the provisional arch is typically completed in a single appointment. The final prosthetic is placed after osseointegration, which takes several months.
Does insurance cover All-on-4 dental implants?
Coverage varies significantly by plan. Some plans cover a portion of implant-related costs; others do not. Sterling Periodontics accepts insurance and reviews coverage before treatment begins. Zero-percent financing is available for qualified patients.
Am I a candidate if I have been told I have too much bone loss for implants?
Possibly. All-on-4 was designed for patients with bone loss, and angled rear implants may reach denser bone that remains after tooth loss. A 3D imaging evaluation is required to confirm candidacy.
What is the difference between seeing a periodontist and a general dentist for All-on-4?
Periodontists complete focused post-doctoral training in bone, gum tissue, and implant surgery. That specialty training applies directly to the surgical and anatomical decisions involved in full-arch restoration.

The Next Step
A 2017 systematic review included 24 studies of the All-on-4 concept and reported 99.8% implant survival beyond 24 months among included reports. Most studies were observational and patient selection, follow-up, and outcomes varied. This is a study result, not a promised result for a new patient or a comparison proving that four implants are best for every jaw.
“Your first visit is a conversation, not a procedure. We send your plan in writing after, so you can think it over at home.”
If you are weighing All-on-4 dental implants in Beverly Hills against individual implants — or trying to figure out whether you are a candidate at all — the most useful thing you can do is get a proper evaluation. Not a phone estimate or a price quote based on a description. An actual clinical evaluation with imaging, a specialist who can answer your specific questions, and a written plan you can take home before committing to anything.
That is what is available at Sterling Periodontics & Implantology on Wilshire Boulevard in Beverly Hills. Schedule a consultation with Dr. Mohamed Khaled and leave with a clear picture of your options — on your own terms, without pressure.
Treatment recommendations, timelines, and outcomes vary by patient and require an in-person clinical evaluation.
