All-on-4 Dental Implants — A Full Smile in One Day

When Most or All of Your Teeth Are Gone — Full-Arch Restoration in One Day

The “All-on-4 / All-on-X” full-arch implant protocol restores a complete arch of teeth on as few as four titanium implants, with the back two angled to maximize bone contact. For Hillsboro and Beaverton patients missing most teeth in an upper or lower arch, it’s a durable and aesthetic alternative to traditional dentures. This technique provides a full-arch prosthesis supported on as few as four implants, making it a cost-effective and minimally invasive procedure. Unlike traditional implants, “all on 4 all on x” reduces the need for bone grafting, making it an excellent option for those with significant bone loss. The International Congress of Oral Implantologists (ICOI) recognizes full-arch implant-supported prostheses as an evidence-based treatment for complete edentulism.

Patients from areas like Aloha and Cornelius appreciate the efficiency of this procedure. With advancements in dental technology, we can provide immediate loading of the prosthesis, meaning you can walk out of our Hillsboro office with a brand new smile in just one day. For those living near Intel Ronler Acres or the Forest Grove area, this means less travel and inconvenience.

The Procedure: What to Expect

The “all on 4 all on x” procedure is meticulously planned and executed to ensure optimal outcomes. Initially, a comprehensive dental examination is conducted to evaluate your oral health and bone structure. Using advanced imaging techniques, we create a 3D model of your jaw to precisely determine the best placement for the implants.

During the surgery, which is performed under sedation, titanium implants are strategically placed in the jawbone. These implants act as anchors for the prosthetic teeth. The entire process, from extraction of any remaining teeth to implant placement and attachment of the temporary prosthesis, is completed in a single visit to our Hillsboro office at 7546 NE Shaleen St, Hillsboro, OR 97124. This streamlined approach minimizes discomfort and accelerates recovery.

Post-surgery, you’ll receive a customized temporary prosthesis. After a healing period of approximately three to six months, during which the implants fuse with your bone (a process known as osseointegration), a permanent prosthesis is attached. This final step ensures the stability and durability of your new teeth.

Why Patients Choose All-on-4 Over Other Options

Three concrete reasons our Hillsboro All-on-4 patients give us most often:

You walk out with teeth. Same-day temporary bridge means you go home the evening of surgery with a working set of teeth. No “denture in a cup” gap month. For patients who’ve been hiding a smile for years, this matters more than the math suggests.

Real chewing comes back. Most patients tell us they had no idea how much chewing they’d given up. Steak, apples, corn on the cob — things they hadn’t eaten in 10-15 years. Standard dentures restore roughly 25-30% of natural bite force; All-on-4 restores 90%+.

Bone stops shrinking. The four implants stimulate the jawbone the way natural tooth roots do. Patients in long-term dentures lose 1-2mm of jawbone per year — over 15 years that’s enough that the lower face starts collapsing inward (the “denture face”). All-on-4 stops this on day one.

The trade-off is upfront cost ($20,000-$35,000 per arch) and a 4-6 month total treatment timeline. Patients who prioritize lower upfront cost and don’t mind a removable prosthesis sometimes prefer a snap-in overdenture instead — see our implant-supported dentures page for that comparison.

Technology and Innovation in All On 4 All On X

The success of “all on 4 all on x” depends almost entirely on accurate surgical placement of the implants. Our Hillsboro practice uses 3D CBCT imaging and computer-guided surgical planning to design each case before surgery — the implants are placed where the bone is densest and where they’ll best support the prosthesis. This planning workflow is what makes high success rates and long-term stability possible.

The materials used for the implants and prosthetics are durable and biocompatible. Titanium, the metal used for the implants, is known for its strength and ability to integrate with bone. The prosthetic teeth are crafted from high-quality acrylic or porcelain, providing a natural appearance and feel.

For patients in Beaverton and beyond, this means peace of mind knowing that their new smile is supported by the latest in dental innovation. Our commitment to continuous learning and adaptation of new technologies ensures that you receive the best care possible.

What Patients Tell Us After All-on-4

The single thing nearly every All-on-4 patient says at their 6-month follow-up is the same: “I had no idea how much I’d been compensating.” Hiding the smile in photos. Cutting steak into tiny pieces. Avoiding the work lunch where there’d be salad. Sleeping with a partial in. After All-on-4, those workarounds disappear inside about 2 weeks of getting the temporary bridge.

Recovery in the first 48 hours is real but manageable. Pressure soreness, some facial swelling that peaks around day 2, fatigue from the surgical stress. We send you home with a prescription for 600mg ibuprofen rotating with 1000mg acetaminophen every 4 hours, ice pack instructions for the first 24 hours, and a soft-food list for the first 6 weeks (yogurt, eggs, mashed potatoes, soft fish, well-cooked pasta). Most patients are back to desk work in 2-3 days. Physical labor: 5-7 days.

The honest hard part isn’t pain — it’s the 6-week soft-food restriction while the bone integrates. Patients who plan ahead (stocking the pantry, lining up smoothie ingredients) handle it well. Patients who don’t sometimes describe it as the most frustrating week of the process. We brief you on this at the consultation.

Candidacy — Who’s a Good Fit and Who Isn’t

All-on-4 was designed for adults missing all or most teeth in an arch — that’s its core indication. The honest filters Dr. Gvozden applies during the CBCT-based consultation:

Strong candidates:

• Adequate anterior bone for the two vertical implants (most patients qualify even with significant posterior bone loss)
• Reasonably controlled medical conditions (HbA1c under 7 for diabetics, no IV bisphosphonates, no recent head/neck radiation)
• Willing to commit to the 4-6 month total timeline and the soft-food window

Cases we discuss carefully or refer:

• Heavy smokers who can’t or won’t quit 2 weeks pre-surgery (failure rate climbs significantly)
• Severe bone atrophy where even angled implants can’t get primary stability — these may need zygomatic implants (referred to specialty centers in Portland)
• Patients with severe bruxism without a willingness to wear a protective night guard
• Active uncontrolled gum disease — we treat this first before placement

If you’ve been told elsewhere you’re not a candidate, get a second opinion with CBCT imaging. Modern angled-implant techniques have made All-on-4 possible for cases that conventional straight-implant protocols can’t handle.

All-on-4 Cost in Hillsboro — Honest Numbers

| Component | Typical Cost (Per Arch) |
|—|—|
| Standard All-on-4 (acrylic-on-titanium prosthesis) | $20,000-$28,000 |
| Premium All-on-4 (zirconia bridge) | $28,000-$35,000 |
| All-on-6 upgrade | +$5,000-$10,000 |
| Bone graft per site (if needed) | $500-$2,000 |
| Sinus lift per side (if needed) | $1,500-$3,000 |
| Both arches at once (full mouth) | $40,000-$65,000 |

Insurance reality: Most dental plans contribute the prosthesis annual maximum ($1,500-$2,000) and often part of the extractions. Implant placement itself is rarely covered. We verify your specific benefits before treatment and put it in writing.

Financing the rest: CareCredit (0% for 24 months on qualifying balances; longer plans with interest beyond), Cherry Health (up to 60 months), Sunbit (up to 72 months). Most All-on-4 patients land on $400-$700 monthly over 36-60 months.

VIP Membership Plan: $299/year takes 15% off — on a $25,000 case that’s $3,750 in real savings. Membership pays for itself many times over on a case this size.

Long-Term Care After All-on-4

The maintenance routine is straightforward but non-negotiable:

• Daily: Brush twice with a soft-bristle brush. Use a Waterpik (water flosser) under the bridge — string floss alone doesn’t reach. The space under the bridge against the gum is where biofilm collects and is the #1 cause of late peri-implant inflammation.
• Every 3 months (first year): Professional cleaning. We use ultrasonic instruments designed not to scratch the titanium-bridge interface.
• Every 4-6 months thereafter: Standard hygiene visit + bite check.
• Annually: Periapical radiograph around the implants to monitor bone level. Catching peri-implantitis early is the single biggest factor in long-term success.
• Every 5-7 years: Dr. Ostovar unscrews the bridge for ultrasonic cleaning of the underside. Composite plugs in the access channels get redone. Same-visit reseating.

If you grind at night, plan on a hard acrylic night guard — bridges fracture from chronic bruxism more often than implants do. We design and deliver the guard at the final restoration appointment.

Long-Term Success Rates and Clinical Evidence

All-on-4 and All-on-X full-arch implant systems have been studied extensively since the protocol was first introduced in the 1990s. Long-term clinical data from the International Congress of Oral Implantologists (ICOI) and peer-reviewed dental journals show 5-year success rates consistently above 95% for both upper and lower arches when the surgery is performed by experienced implant teams using proper planning and technique.

At East Wind Dental Care in Hillsboro, three doctors place implants — Dr. Ostovar (FAGD), Dr. Gvozden (Tufts-trained, 30+ years oral surgery), and Dr. Youngblood (OHSU DMD). Dr. Ostovar and Dr. Gvozden have completed hundreds of full-arch and complex implant cases over the past 15+ years, and our outcomes align with published clinical benchmarks. The key factors that drive long-term success include accurate pre-surgical CBCT planning, strategic implant placement in areas of dense bone, immediate loading protocols that allow osseointegration without overloading the implants during healing, and patient adherence to post-operative care instructions.

Implant failure — when it occurs — typically happens within the first six months during the osseointegration phase, often due to infection, excessive bite forces before healing is complete, or uncontrolled systemic conditions like unmanaged diabetes or heavy smoking. Once the implants have fully integrated (usually 3–6 months), the 10-year survival rate for properly maintained All-on-4 prostheses exceeds 90%, comparable to traditional implant-supported bridges.

Our Hillsboro team uses 3D CBCT imaging and computer-guided surgical planning software for every full-arch case to minimize surgical risk and maximize implant positioning accuracy. This technology-driven workflow, combined with our three-doctor collaboration model, allows us to handle complex cases — including patients with significant bone loss who may have been told elsewhere they are not candidates — and deliver predictable, durable outcomes.

Frequently Asked Questions — All-on-4 in Hillsboro

Quick Reference Facts — All-on-4 Dental Implants at East Wind Dental Care

• Cost Range (2026): All-on-4 with acrylic bridge $20,000-$28,000 per arch, premium zirconia bridge $28,000-$35,000 per arch. Both arches (full mouth) $40,000-$65,000. All-on-6 upgrade adds $5,000-$10,000 per arch. Cost includes extractions, 4 titanium implants, same-day temporary bridge, and final fixed prosthesis after osseointegration.
• Insurance Coverage: Most plans contribute toward extractions and annual prosthetic maximums ($1,500-$2,000). Implant placement itself is rarely covered. We verify your specific benefits before treatment and provide written cost breakdown. Expect to finance the majority.
• Treatment Timeline: Surgery and same-day temporary bridge completed in one day (4-6 hours per arch). Final permanent prosthesis delivered 3-6 months later after osseointegration (bone-implant fusion). “Teeth in a day” refers to the temporary bridge, not the final permanent restoration.
• Candidacy — Good Fit: Adults missing all or most teeth in an arch, with adequate anterior bone for 2 vertical implants (angled posterior implants work with less posterior bone). Reasonably controlled systemic conditions. Ability to handle a 4-hour surgical visit.
• Candidacy — NOT Recommended: Uncontrolled diabetes (HbA1c above 7-8), heavy smokers unwilling to quit for 2+ weeks before surgery, severe bone atrophy where angled implants cannot achieve primary stability, or untreated severe bruxism without willingness to wear a night guard post-restoration.
• Technology — 3D CBCT Planning: Every All-on-4 case uses 3D cone beam CT imaging and computer-guided surgical planning. Implants are placed where bone density and arch support are optimal. This digital workflow is the primary driver of high long-term success rates.
• Number of Visits: Consultation + CBCT scan → surgical placement day (same-day temporary) → 1-week post-op check → 4-week check → 3-month check → final impression → permanent bridge delivery. Total 6-7 appointments over 4-6 months. Professional cleanings every 3 months in the first year.
• Pain/Recovery Timeline: First 48 hours: pressure soreness and facial swelling (peaks day 2), fatigue from surgical stress. Managed with rotating ibuprofen 600mg + acetaminophen 1000mg, ice packs first 24 hours. Most patients return to desk work in 2-3 days. The most significant restriction: soft-food diet for 6 weeks during bone integration.
• Success Rate/Longevity: 10-year implant survival rate exceeds 90% with proper maintenance and hygiene. Implants typically last 20+ years, often lifetime. The bridge prosthesis is the wear component: acrylic-on-titanium needs refurbishment at 7-10 years (~$6,000-$10,000 per arch); zirconia bridges last 15-20+ years.
• Provider Credentials: Dr. Merat Ostovar, DMD, FAGD, with 15+ years experience and 2,500+ implant procedures completed in Hillsboro. CBCT-guided planning on every full-arch case. Fellow of the Academy of General Dentistry — a credential held by fewer than 7% of general dentists nationwide.
• Financing Options: VIP Membership Plan ($299/year) saves 15% — on a $25,000 case, that’s $3,750 in real savings. CareCredit 0% interest for 24 months, Cherry Health up to 60 months, Sunbit up to 72 months. Most patients: $400-$700 monthly over 36-60 months. Free consultation with CBCT imaging.
• All-on-4 vs. Dentures: All-on-4 is fixed (not removable by patient), restores 90%+ chewing force, prevents bone loss, and feels like natural teeth. Traditional dentures are removable, restore only 20-40% chewing force, do NOT prevent bone loss, and often need adhesive. Implant overdentures are a middle option — removable but snap onto implants, restore 60-80% chewing force.
• Fixed vs. Snap-In: All-on-4 bridge is screwed into implants — only a dentist can remove it (done every 5-7 years for deep cleaning). You brush it in your mouth like natural teeth; you don’t remove it at night. Snap-in overdenture is removable for cleaning. Most patients prefer the fixed feel — it’s closer to natural teeth.
• Daily Care: Brush twice daily with soft-bristle brush. Water flosser (Waterpik) under the bridge daily — the space between the bridge and gum is where biofilm collects, the primary cause of long-term peri-implant inflammation. String floss alone doesn’t reach well. Professional cleanings every 3-4 months.
• All-on-4 vs. All-on-6: All-on-4 uses 4 implants (2 vertical front, 2 angled back at 30-45 degrees). All-on-6 uses 6 implants for more distributed support. All-on-6 is recommended for heavy bite forces, larger arch spans, or bone density patterns favoring more support points. Adds $5,000-$10,000 per arch. The implant count is a clinical decision based on your CBCT, not a sales upgrade.
• Long-Term Cost Comparison: All-on-4 30-year total cost (including one bridge refurbishment) is typically lower than replacing conventional dentures every 5-7 years plus relines, adhesive, and treatment for accelerating bone loss.
• Special Considerations — Smoking: Heavy smokers have significantly higher implant failure rates. We require a 2-week quit period before surgery. Continuing to smoke during healing materially increases risk of failure and infection. Honest smoking history is essential for accurate risk counseling at consultation.

How much do All-on-4 implants cost in Oregon?

Across Oregon, All-on-4 typically runs $20,000-$35,000 per arch as of 2026. At our Hillsboro office on Shaleen Street, that range covers all extractions of failing teeth, four titanium implants placed by Dr. Gvozden (Tufts-trained, 30+ years surgical), the same-day temporary bridge, and the final fixed prosthesis after 3-6 months of osseointegration. Both arches together: $40,000-$65,000. Premium materials (zirconia bridge vs. acrylic) push the upper end. CareCredit, Cherry Health, and Sunbit financing typically bring monthly payments to $400-$700 over 36-60 months. VIP Membership members save 15%.

How long do All-on-4 implants last?

The titanium implants themselves typically last 20+ years and often a lifetime once they’ve fully osseointegrated. The bridge prosthesis on top is the wear part: an acrylic-on-titanium bridge typically needs refurbishing or replacement at 7-10 years; a zirconia bridge lasts 15-20+. Long-term published 10-year survival of the full-arch prosthesis is above 90% when patients keep up with 3-month hygiene visits and use a water flosser daily. The single biggest cause of late failure we see is heavy unrelieved grinding without a night guard.

What is the downside of All-on-4 dental implants?

Honest answer: All-on-4 is a serious surgical procedure and a serious investment. The downsides Hillsboro patients should weigh: cost ($20,000-$35,000 per arch, financing required for most), 3-6 month healing window before final teeth are seated, more strict daily hygiene than natural teeth (water flosser under the bridge daily, professional cleanings every 3 months), and surgical risk inherent to any sedation procedure. For patients with active uncontrolled diabetes, heavy smoking, or recent head/neck radiation, the failure risk climbs and we may recommend a snap-in overdenture instead.

Can All-on-4 be done in one day?

The surgical placement and the same-day temporary teeth are done in one day — typically 4-6 hours per arch. You go home that evening with a working temporary bridge attached to the implants. What’s NOT done in one day: the final permanent prosthesis. The implants need 3-6 months of osseointegration before the final zirconia or acrylic bridge can be seated, because the temporary is intentionally engineered to stay slightly out of full bite while the bone fuses. The “teeth in a day” marketing language refers to the temporary, not the final restoration.

Are All-on-4 implants permanent?

Yes — fixed and not removable by you. The bridge is screwed into the four implants and only Dr. Ostovar can remove it (which we do every 5-7 years for a deep professional cleaning of the prosthesis underside). You don’t take it out at night, you don’t soak it, you brush it in your mouth like natural teeth. That’s the practical difference between All-on-4 and a snap-in overdenture: the overdenture is removable for cleaning; All-on-4 is fixed.

What’s the difference between All-on-4 and All-on-6?

All-on-4 uses four implants per arch — two vertical in front where bone is densest, two angled at 30-45 degrees in back. All-on-6 uses six implants spread more evenly. When does the extra count matter? Patients with heavier bite forces (heavy grinders, larger arch span), patients who want maximum long-term stability margin, or patients with bone density patterns that favor more support points. All-on-6 costs $5,000-$10,000 more per arch. Dr. Gvozden picks the count from your CBCT — clinical decision based on your bone, not a sales upgrade.

Who is a candidate for All-on-4?

Most adults missing all or most teeth in an arch — that’s exactly the population the protocol was designed for. Specifics: at least minimal bone in the anterior maxilla or mandible (the angled posterior placement avoids the sinus and finds bone where straight implants can’t), reasonably controlled medical conditions, and ability to handle a 4-hour surgical visit. Heavy smokers see higher failure rates and we’ll ask you to quit 2 weeks before. If you’ve been told elsewhere you’re not a candidate due to bone loss, get a CBCT-based second opinion.

Can All-on-4 implants be removed by the patient?

No — the bridge is screwed into the implants and only Dr. Ostovar can unscrew it. We do this every 5-7 years for a deep professional cleaning of the underside of the prosthesis. The screw access channels are sealed with composite that we drill out, unscrew the bridge, clean it ultrasonically, and replace it the same visit. If you want a removable solution you can take out at night, you want a snap-in overdenture instead — which uses fewer implants and lower cost but is genuinely removable.

How do I clean All-on-4 implants?

Daily routine: brush twice a day with a soft-bristle toothbrush like natural teeth, floss under the bridge using either a Waterpik (water flosser, by far the easiest) or Super Floss / Oral-B Superfloss with a stiff threader end. The space under the bridge against the gum is where biofilm collects and is the #1 cause of long-term peri-implant inflammation. Professional cleanings every 3 months (not 6) for the first year, then 4-6 months thereafter. We also unscrew and ultrasonically clean the bridge underside every 5-7 years.

Will All-on-4 ever need to be replaced?

The implants — typically no, they last 20+ years and often the rest of your life. The bridge prosthesis on top — yes, eventually. An acrylic-on-titanium bridge typically needs refurbishing at 7-10 years; a zirconia bridge holds up 15-20 years before fracture or wear forces replacement. Refurbishing is roughly 1/3 the cost of the original case ($6,000-$10,000 per arch for our Hillsboro patients). Heavy grinders should plan on shorter intervals and budget for a protective night guard.
