All-on-4 for Covina Patients

All-on-4 replaces an entire upper or lower arch of teeth with a fixed bridge supported by four dental implants — two placed toward the front of the jaw and two angled toward the back to engage the bone you still have. It doesn't come out, doesn't need adhesive, and doesn't shift when you eat.

Covina sits close enough to our Sunset Ave office that most patients drive over on a lunch break for their consultation. That proximity matters more than it sounds for All-on-4, because full-arch treatment isn't one appointment — it's a surgical day, a handful of healing checks over the following months, and a final bridge fitting. A short drive turns each of those from an ordeal into an errand.

American Dental Group has been the implant practice for Covina residents for over two decades. All-on-4 cases here are planned and placed by Dr. Homan Hanasab, a board-certified periodontist — the specialty trained in the bone and gum foundation that a full-arch case depends on.

Also called All-on-X.

The “4” is a brand name rather than a fixed rule. The number of implants is set by your bone volume and bite — commonly four to six per arch — and Dr. Hanasab decides it from your 3D scan. Either way the result is one fixed full-arch zirconia bridge, not separate crowns on each implant.

Why Covina Patients Choose Full-Arch Implants Here

One office, start to finish

The 3D scan, the extractions, the implant surgery, the same-day provisional bridge, and the final zirconia bridge all happen at 436 N. Sunset Ave. Nothing is referred out to a surgical center across the valley, and one specialist stays accountable for the outcome.

Same-day teeth

In most Covina cases we place the four implants and attach a fixed provisional bridge in the same appointment. You drive home with a full arch, not an empty mouth.

Follow-ups that don't cost you a day

Osseointegration takes months and involves periodic checks. From Covina that's a five-minute trip rather than a freeway commitment.

A written estimate before you commit

You leave the consultation knowing what your case costs, what your insurance is expected to cover, and what financing looks like — before agreeing to anything.

What Treatment Looks Like

Full-arch implant treatment runs over several months. From Covina, the trip to each appointment is about 5 minutes.

  • Consultation and 3D CT scan. Bone volume, nerve position, and a digital plan for every implant — plus a written estimate.
  • Extractions and implant placement. Failing teeth out and four implants in, usually the same appointment. Sedation available.
  • Same-day fixed provisional bridge. You leave with teeth, not an empty arch.
  • Healing and osseointegration. Soft foods for one to two weeks, then periodic checks over several months. See our post-op care guide.
  • Final bridge. A custom permanent bridge in a durable material such as zirconia, fitted and adjusted to your bite.

Your Implant Specialist

All-on-4 cases are planned and placed by Dr. Homan Hanasab, a board-certified periodontist and dental implant specialist with more than 25 years of experience, and team dentist for the LA Clippers. Periodontists are the specialists trained in the gum and bone foundation implants rely on — which is precisely what determines whether a full-arch case lasts.

Consultation, surgery, the provisional bridge, and the final restoration all take place at our West Covina office. Covina patients aren't handed off to a separate surgical practice partway through treatment.

All-on-4 Questions from Covina Patients

How far is your office from Covina?

About 5 minutes. From Covina, head south on Citrus Ave, turn right onto San Bernardino Rd, then left onto Sunset Ave. We're at 436 N. Sunset Ave in West Covina with free on-site parking.

Can I have my All-on-4 consultation and surgery at the same visit?

No, and you shouldn't want to. The consultation includes a 3D CT scan that we use to plan every implant position digitally before surgery. Surgery is scheduled separately once that plan and your written estimate are agreed on.

Do you offer sedation for All-on-4 surgery?

Yes. Full-arch implant placement is a longer appointment than most dental work, and we offer sedation options so patients can get through it comfortably. We discuss what's appropriate for you at the consultation.

I already wear a denture. Can I switch to All-on-4?

Very often, yes — denture wearers are among the most common All-on-4 candidates. Years under a denture usually mean some bone loss, but the angled rear implants in All-on-4 are specifically designed to work with reduced bone, which is why patients previously turned down for implants frequently qualify.

Getting here from Covina

Our office is at 436 N. Sunset Ave, West Covina, CA 91790 — 2.6 miles from Covina, about 8 minutes without traffic. Head west on San Bernardino Road, then turn right onto Sunset Avenue. If you prefer the freeway, take the 10 west and exit at Sunset Avenue. Parking on site is free.

Covina is the closest city to our office after West Covina itself, and Covina patients make up one of our largest groups. Most tell us the drive is shorter than crossing their own town.

Where our Covina patients come from

We see patients from downtown Covina and Citrus Avenue, Covina Park, Heritage Plaza, Charter Oak and the neighbourhoods off Badillo Street. If you are anywhere in Covina, you are inside the four-to-five-mile radius most of our practice sits in — Covina is just east of us, and the trip is one freeway exit or one main road for almost everyone.

Why Covina patients come to us for All-on-4 full-arch implants

The short version is the credential. Dr. Homan Hanasab holds a DDS plus an MS in Periodontics and a Certificate of Advanced Graduate Studies, and he is the LA Clippers team dentist. A general practice closer to you can handle a cleaning and a filling; what it usually cannot do is place implants into compromised bone, graft it first, or manage gum disease that has gone past the surface. Those all happen in this office, with one clinician responsible from the scan to the final result.

That also means no referral out and back. For a patient driving in from Covina, the practical difference is fewer trips, not just a shorter one.

Questions from Covina

Covina patient FAQ

Is All-on-4 worth travelling from Covina for?

It is 2.6 miles, about 8 minutes without traffic, and full-arch work is not something most general practices offer. Head west on San Bernardino Road, then turn right onto Sunset Avenue. If you prefer the freeway, take the 10 west and exit at Sunset Avenue. Surgery day is the longest appointment; bring a driver.

Will I leave with teeth on the day of surgery?

In most cases, yes. A fixed provisional bridge is attached to the implants the same day or shortly after, so you do not go home without teeth. The permanent bridge is fitted once the implants have fused, which takes several months.

What if I have been told I don't have enough bone?

That is one of the reasons All-on-4 exists. Two of the four implants are angled to use the denser bone toward the front of the jaw, which often avoids the sinus grafting a conventional full-arch case would need. A 3D scan gives a definitive answer.
