All-on-4® Dental Implants in Agoura Hills, CA

All-on-4® is the gold-standard solution for replacing a full arch of missing or failing teeth — using just four strategically placed implants per arch. At Agoura Advanced Dentistry, Dr. Kambiz Kamangar plans every All-on-4 case with 3D cone-beam imaging and, in many cases, can deliver a fully fixed temporary bridge the same day as surgery. No removable dentures, no covering the roof of your mouth, no compromise on chewing power.

All-on-4 is the right tool for patients missing all teeth in one or both arches, those with failing teeth that aren’t worth saving, current denture wearers seeking a permanent solution, and people previously told they don’t have enough bone for implants — All-on-4’s angled posterior implants often work even with significant bone loss.

Who Is the Right Candidate for All-on-4?

All-on-4® is the right tool for a specific patient profile. The 3D consultation will tell us exactly where you fit, but here’s the general framework:

Strong All-on-4 Candidates

• Currently wear conventional dentures and want a fixed, permanent solution — no slipping, no adhesives, no removing them at night.
• Have failing teeth that aren’t worth saving — advanced periodontal disease, multiple large fractures, root resorption affecting most of an arch.
• Are missing all or most teeth in one or both arches already.
• Have been told elsewhere they “don’t have enough bone for implants.” All-on-4’s angled posterior implants engage denser bone in front of the sinus or nerve, often eliminating the need for grafting.
• Want predictable certainty. All-on-4 is all-inclusive — one price covers consultation, imaging, surgery, temporary, and final prosthesis.
• Are healthy enough for outpatient surgery. Most medical conditions are manageable with planning. We coordinate with your physician when needed.

When We Recommend a Different Approach

• If you have only 1–3 teeth missing, individual implants or an implant-supported bridge is usually the better choice — less invasive, lower
• If you have severe bone resorption beyond what angled implants can compensate for, we may recommend All-on-6 (six implants) or a combination of implants plus bone grafting before placement.
• If you have a heavy bite, bruxism, or grinding habits, All-on-6 distributes load across two extra implants and gives you a safer long-term margin.
• If you’re a poor surgical risk (uncontrolled diabetes, active heart conditions, certain medications), we coordinate with your physician and may stage the procedure or recommend an alternative.

What Happens If You Do Nothing

This is the conversation patients rarely have with themselves. If you have failing teeth or wear ill-fitting dentures and choose to “live with it,” here’s what typically happens over time:

Bone Loss Accelerates

The jawbone needs the stimulation of tooth roots (or implants) to maintain density. Without that stimulation, the bone resorbs at roughly 25% in the first year after tooth loss and continues progressively. Patients who wait 5+ years often need significant grafting before implants are even possible — adding and 6–9 months of healing time to whatever treatment plan they eventually choose.

Facial Structure Changes

The lower third of the face is supported by your teeth and jawbone. As bone is lost, the chin moves up and forward, lips thin, and the face takes on the “sunken” appearance that ages patients prematurely. This is reversible with implants. It is not reversible with dentures alone.

Nutritional Decline

Patients with failing teeth or loose dentures unconsciously stop eating tough vegetables, lean proteins, and fibrous fruits. Studies show measurable shifts toward soft, calorie-dense, lower-nutrient foods within 12 months of significant tooth loss.

Social and Confidence Impact

This one’s hard to quantify but every patient describes it. Avoiding photos, speaking with a hand near the mouth, declining dinner invitations. The decision to do something — anything — about your teeth almost always comes after years of these small daily compromises stacking up.

Post-Op Timeline: Day 1 Through Year 1

Knowing what to expect makes the recovery far easier. Here’s the typical timeline our patients experience:

Day of Surgery

• Procedure takes 2–4 hours per arch under local anesthesia (with optional sedation).
• You leave with a fixed temporary bridge — full set of teeth from the moment you walk out.
• Mild numbness, some swelling. Most patients drive themselves home if no sedation was used.
• Soft food only for the first 24 hours (smoothies, yogurt, mashed potatoes).

Days 2–7

• Swelling peaks at 48–72 hours then recedes.
• Most patients return to work on day 3–5.
• Continue soft diet. Salt-water rinses 4× daily.
• Follow-up visit at day 7 to check the temporary fit and remove sutures.

Weeks 2–6

• Soreness fully resolves by week 2.
• Diet expands to soft cooked foods (pasta, fish, well-cooked vegetables).
• You learn to clean around the temporary bridge.
• Most patients describe this as “the new normal” by week 3–4.

Months 2–4

• Osseointegration is happening (the bone fusing with the implants). You can’t feel it.
• You’re eating most foods comfortably. Hard, crunchy items still require care.
• One progress check-in around month 3.

Months 4–6

• Final impressions taken once integration is verified.
• Final prosthesis fabricated by our master ceramist (2–4 weeks).
• Final placement: temporary off, final on. This is “the second day you got your smile back.”

Year 1 and Beyond

• Hygiene visits every 6 months — same as natural teeth.
• You eat normally. 90% of natural chewing power.
• Most patients describe All-on-4 as feeling like real teeth within 60–90 days. Within a year, they forget it’s even a prosthesis.

How to Decide If All-on-4 Is Right for You

The honest answer is that you can’t decide from a website. The decision needs a 3D scan, a bite analysis, and a face-to-face conversation about your goals, health, and budget. What you can do from a website is screen yourself in or out:

• If you’re missing all or most teeth in an arch and have been told you can’t get implants because of bone loss — book a consultation. All-on-4 was specifically designed for your situation.
• If you wear dentures and they’re not staying put — book a consultation.
• If you have failing teeth and a dentist has been recommending crown after crown to “save” them — book a consultation. Sometimes the right answer is to start over with a fixed full-arch solution.
• If you’re missing only 1–3 teeth — All-on-4 isn’t the right answer for you. Look at single-tooth implants or implant-supported bridges instead.
• If you have heavy bite or significant bone loss — look at All-on-6 as a stronger alternative.
