All-on-4 Dental Implants
All-on-4 Dental Implants is a specialized dental service provided by the board-certified specialists at Aloha Dental Specialty Center in Beaverton, OR. A full arch of fixed teeth on just four implants — often with teeth delivered the same day as surgery.
We know dental care can be stressful. Our team goes out of their way to make every visit comfortable, clear, and unhurried.
Four Implants, Twelve Teeth, One Surgery — The All-on-4 Explained
All-on-4 is a specific surgical and prosthetic protocol that uses exactly four implants to support a complete arch of fixed teeth. The two anterior implants are placed vertically in the dense bone between the mental foramina (lower) or in the premaxilla (upper). The two posterior implants are tilted at 30 to 45 degrees to engage longer lengths of bone while avoiding the maxillary sinuses above and the inferior alveolar nerve below. This angulation eliminates the need for bone grafting in most cases — which is what makes All-on-4 a major improvement for patients who have been told they lack sufficient bone.
The protocol was developed by Dr. Paulo Malo in Portugal and has over 20 years of peer-reviewed clinical data supporting its reliability. At our Beaverton office, Dr. Ostovar performs All-on-4 cases with CBCT-guided surgical planning and digitally designed prosthetics. On surgery day, failing teeth are extracted, implants are placed, and a pre-fabricated provisional prosthesis is attached to the implants — all in one visit. You leave with a full set of fixed, non-removable teeth that same day.
The provisional prosthesis is worn for four to six months while the implants integrate with the bone. During this period, you eat a soft diet to avoid overloading the healing implants. Once integration is confirmed by follow-up imaging, we replace the provisional with a final prosthesis — typically a milled zirconia bridge with individually characterized teeth. This final restoration is designed for decades of function: stain-resistant, chip-resistant, and indistinguishable from natural teeth.

Understanding Your Investment
At Aloha Dental Specialty Center, we provide transparent pricing before any treatment begins. The cost of your procedure depends on clinical complexity, materials used, and sedation requirements. We walk you through every line item during your consultation so there are no surprises.
What Affects Cost:
- Clinical Complexity: Bone loss, sinus proximity, nerve involvement, or the need for grafting affects treatment planning and surgical time.
- Materials: We use research-backed implant systems, purified bone graft matrices, and high-strength ceramics from established manufacturers.
- Sedation: Options range from local anesthesia to IV sedation, each with different associated costs. We discuss the best option for your comfort and procedure.
Insurance & Financing
We accept most major dental insurance plans and file claims on your behalf. Our team verifies your benefits before treatment and submits pre-treatment estimates with clinical documentation to maximize coverage.
For out-of-pocket costs, we partner with CareCredit and Cherry for flexible payment plans. We also offer our ADSC Dental Savings Plan for patients without insurance.
Recovery & Healing Timeline
Understanding the healing process helps you plan ahead and follow post-operative instructions for the best possible outcome.
First 48 Hours
Mild swelling and tenderness are normal. Apply ice packs in 20-minute intervals and take prescribed or over-the-counter anti-inflammatory medication. Eat soft foods and avoid the surgical site when chewing.
Days 3 to 7
Swelling peaks around day three and then improves. The tissue begins closing over the surgical site. Continue with soft foods and use any prescribed antimicrobial rinse. Most patients return to normal activities during this phase.
Long-Term Healing
Surface tissue heals within two to three weeks. Bone integration and deep healing continue for three to six months. Avoid smoking, follow up as scheduled, and maintain good oral hygiene throughout recovery.

The Biomechanics of Tilted Implants: More Bone Contact Without Grafting
Tilting posterior implants at 30 to 45 degrees is not a compromise — it is a biomechanical advantage. By angling the implant along the anterior wall of the maxillary sinus or the mental foramen shelf, the implant engages up to 50 percent more bone length than a vertical implant in the same location. The increased anterior-posterior (A-P) spread between the front and back implants reduces cantilever forces on the prosthesis. Studies show that tilted implants achieve primary stability values (insertion torque of 35+ Ncm) equivalent to or greater than vertical implants, and long-term survival rates are statistically identical at 98 percent or above over 10-year follow-ups.
Why Choose a Specialist?
All-on-4 is a protocol, not a product — and outcomes depend entirely on the clinician executing it. The angles of the posterior implants, the decision to load immediately or stage, the design of the provisional prosthesis, and the management of the healing diet all require judgment born from extensive experience. Dr. Ostovar has completed hundreds of All-on-4 cases and manages both the surgical and prosthetic phases personally. His ICOI fellowship included dedicated training in immediate-load full-arch protocols. Not every clinician offering "teeth in a day" has this level of specialized training.

From Dr. Ostovar: What I Tell My Implant Patients
“In my experience placing thousands of dental implants, I’ve found that the patients who do best are the ones who understand what they’re getting into. It’s not a painful procedure — most people tell me it was easier than the extraction. But it is a process. You’re looking at 3-6 months from implant placement to final crown, sometimes longer if we need to build bone first.
I won’t sugarcoat it: not every patient is a candidate right away. If you’ve had teeth missing for years, you’ve likely lost bone. That doesn’t mean you can’t get implants — it means we may need a bone graft or sinus lift first. I’d rather take the time to build a solid foundation than rush and risk failure.
The materials matter too. We use Nobel Biocare and Straumann titanium implants — these are the systems with the best long-term research behind them. For the crown, I typically recommend zirconia or e.max porcelain depending on the location in your mouth. Front teeth get a different material consideration than molars.
If you’re comparing costs, a single implant at our Beaverton office runs $3,500-$5,500 including the crown. That’s competitive for the Portland metro area, and we offer CareCredit 0% financing. Most PPO dental insurance plans now cover a portion of implant costs — our team will verify your benefits before we start.”

Frequently Asked Questions
What does All-on-4 mean exactly?
All-on-4 refers to a full arch of teeth ("all") supported on ("on") four dental implants ("4"). It is a trademarked protocol developed by Nobel Biocare based on Dr. Paulo Malo's research. The technique uses two straight anterior implants and two tilted posterior implants to support a fixed, non-removable prosthesis of 10 to 14 teeth.
Do I really get teeth the same day as surgery?
Yes, in most cases. Dr. Ostovar places the four implants and attaches a prefabricated provisional prosthesis on the same day. You leave our Beaverton office with a full set of fixed teeth. These provisional teeth are functional and aesthetic, though they will be replaced with a stronger final prosthesis after the implants integrate.
How much does All-on-4 cost at your Beaverton office?
A single arch All-on-4 treatment typically ranges from $22,000 to $30,000, which includes all implants, extractions if needed, the provisional prosthesis, and the final zirconia prosthesis. Upper arches tend to cost slightly more due to bone density considerations. We provide exact pricing after your CBCT consultation.
Is All-on-4 safe for someone with bone loss?
This is exactly the patient population All-on-4 was designed for. The tilted posterior implants bypass areas of bone loss — particularly around the maxillary sinuses — by engaging denser bone further forward and at an angle. Many patients who were told they need extensive bone grafting for traditional implants are excellent All-on-4 candidates without any grafting.
What is the difference between All-on-4 and All-on-6?
All-on-4 uses four implants; All-on-6 uses six for additional support. The choice depends on bone quality and the patient's bite force. Six implants distribute load across more points, which can be advantageous in patients who clench or grind. Dr. Ostovar recommends the approach that best fits your anatomy.
How long does All-on-4 surgery take?
The surgical phase takes approximately two to three hours per arch. Adding extractions, prosthetic fitting, and adjustments, the total appointment runs about four to six hours for a single arch. The procedure is performed under IV sedation, so the time passes quickly and you will not remember the details.
What can I eat after All-on-4 surgery?
For the first three months, you follow a soft-food diet: scrambled eggs, pasta, fish, mashed potatoes, yogurt, smoothies, and similar foods. This protects the implants during the critical integration period. After the final prosthesis is placed, you can eat virtually anything — steak, raw vegetables, crusty bread, and all the foods you have been missing.
Will All-on-4 implants look natural?
Yes. The final zirconia prosthesis includes individually shaped teeth with natural color variations and realistic gum-colored material. We digitally design the smile to complement your facial proportions, lip line, and skin tone. Patients routinely tell us that friends and family cannot tell they have implants.
How long do All-on-4 implants last?
The four titanium implants are designed to last a lifetime with proper care. The prosthesis (the visible teeth and gum structure) typically lasts 15 to 25 years before needing refurbishment. Zirconia prostheses tend to outlast acrylic versions. Regular maintenance appointments every six months are important for longevity.
Is All-on-4 better than traditional dentures?
In almost every measurable way, yes. All-on-4 restores 80 to 90 percent of natural bite force versus 20 to 30 percent with dentures. There is no slipping, no adhesive, no palate coverage, and no accelerated bone loss. The psychological benefit of permanently fixed teeth is also significant. The only advantage of dentures is lower upfront cost.
What is the success rate of All-on-4?
Published literature reports All-on-4 survival rates of 95 to 99 percent at the 10-year mark. Dr. Ostovar's practice outcomes align with the upper end of this range. The most common complication is not implant failure but provisional prosthesis fracture during the healing phase, which is easily repaired.
Can smokers get All-on-4?
Smoking increases the risk of implant failure significantly. We require patients to stop smoking at least two weeks before surgery and strongly recommend permanent cessation. If quitting is not possible, we discuss the improved risks honestly. Some smokers proceed with All-on-4 successfully, but the risk-benefit conversation is essential.
What happens if I need extractions before All-on-4?
Extractions are performed at the beginning of the same surgical appointment. Failing teeth are removed, the sockets are cleaned and grafted if needed, and the implants are placed in the best pre-planned positions. There is no need for a separate extraction appointment in most cases.
How is All-on-4 different from snap-on dentures?
All-on-4 produces a fixed prosthesis that is permanently screwed onto the implants — only a dentist can remove it. Snap-on dentures (overdentures) are removable; you take them out nightly for cleaning. All-on-4 feels more like natural teeth, provides stronger bite force, and better preserves bone, but costs more.
Do you offer financing for All-on-4?
Yes. We work with several third-party financing companies that offer plans with low or zero interest for qualified applicants. Monthly payments can make All-on-4 surprisingly accessible. Our treatment coordinator will review all financial options at your consultation so cost does not prevent you from getting the care you need.
