All-on-4 Implants

Replace Your Entire Smile With Just Four Implants

All-on-4 is a revolutionary full-arch restoration that uses four strategically placed Straumann implants to support replacement teeth for an entire upper or lower jaw—or both. If you’re missing all your teeth or wearing dentures you’ve grown to hate, All-on-4 offers a permanent, comfortable, natural-functioning alternative that actually preserves your jawbone and facial structure.

The genius of All-on-4 is biomechanical efficiency. Two implants are positioned vertically in the front jaw where bone is densest. Two are tilted at 45 degrees in the back, anchoring to available bone and distributing bite forces ideally. This configuration eliminates the need for bone grafting in 70-80% of cases, reduces surgery time, and delivers stability equal to or exceeding traditional multiple-implant approaches.

Why All-on-4 Beats Dentures and Individual Implants

Compared to Dentures: Dentures sit on your gums, shifting when you chew. You’ll spend decades cleaning them nightly, using adhesives, managing adjustments and replacements, and experiencing jawbone loss because dentures do not prevent the natural bone resorption that occurs after tooth loss. All-on-4 implants are fixed permanently into your bone, don’t move, require normal brushing and flossing, function like natural teeth, and preserve your jawbone for life. After years of dentures, All-on-4 feels like getting your life back.

Compared to Individual Implants per Tooth: Replacing all upper or lower teeth with individual implants requires 10+ implants, extensive surgery, often bone grafting, and 6-12 months of treatment. All-on-4 uses just four implants, minimizes surgery, usually eliminates grafting, and is significantly more cost-effective. You get nearly identical function and longevity at a fraction of the cost and complexity.

The All-on-4 Process Step-by-Step

Phase 1: Consultation & Evaluation You meet with our implant-trained doctor. We examine your mouth, review your history, and take CBCT imaging (3D X-rays) to measure bone in precise detail. We determine implant positions, assess whether grafting is needed, discuss the temporary prosthesis (teeth you’ll wear immediately), and plan your timeline. You leave understanding exactly what to expect.

Phase 2: Surgical Day (Implant Placement & Immediate Loading) You arrive at our office where we administer local anesthesia to ensure you feel no pain. Our doctor surgically places four Straumann implants in their pre-planned positions. For two of them, gentle tilting angles (30-45 degrees) allow them to seat deeply into posterior bone, providing ideal load distribution. Total surgery time is typically 60-90 minutes. You feel no pain (you’re numb), though you’ll sense pressure and vibration.

Immediate Prosthesis (Same Day): Within hours, your temporary teeth are attached to the implants. This is a full arch of replacement teeth fabricated beforehand to your specifications. You leave with teeth—no gaps, no missing smile. The temporary is functional, comfortable, and looks natural. Many patients are amazed they can eat soft foods and resume their life immediately.

Phase 3: Recovery (First 2 Weeks) Mild to moderate swelling peaks at day 2-3, then gradually resolves. You may have bruising. Discomfort is easily managed with prescribed or over-the-counter pain medication. You can eat soft foods (using your temporary teeth) from day one. No straw use, smoking, or alcohol for 5 days. Keep the surgical sites clean. Most patients feel nearly normal by day 7.

Phase 4: Osseointegration (3-6 Months) This is the critical phase where your bone fuses to the implants. You wear your temporary teeth normally—eating, speaking, smiling. You cannot feel this happening, but it’s essential. Straumann implants typically achieve full integration in 3-4 months. During this time, maintain excellent oral hygiene and attend follow-up appointments to monitor healing.

Phase 5: Final Restoration (Permanent Prosthesis) Once osseointegration is complete, we remove your temporary prosthesis and have your lab fabricate your final restoration. Your permanent All-on-4 teeth are custom-designed in shade, shape, and function to match your facial features and bite perfectly. We verify fit, adjust bite alignment, and permanently screw the prosthesis to your implants. You leave with a restoration designed to last 20-30 years with proper care.

All-on-4 Implant Configuration Explained

Anterior Implants (2 vertical): Placed in the front of your jaw where bone is naturally deep and dense. These are positioned vertically (perpendicular to your jaw) and serve as primary load-bearers, anchoring the front teeth and providing stability.

Posterior Implants (2 tilted): Placed in the back of your jaw at 30-45 degree angles, tilting toward the front. This tilting:

• Uses deeper, denser bone at the angle
• Maximizes bone contact and load-bearing surface
• Often eliminates the need for bone grafting
• Distributes bite forces more efficiently than if they were vertical

This biomechanical design was developed in Europe and has decades of clinical evidence supporting success rates of 95%+ at 10+ years.

All-on-4 vs. All-on-6 vs. Zygoma Implants

All-on-4: Standard approach, four tilted implants, works for 70-80% of patients, most economical.

All-on-6: Six implants (four tilted posterior, two vertical anterior) for patients with more bone or who prefer maximum implant support. Higher cost, marginal improvement in outcomes for most patients.

Zygoma Implants: Anchored to the cheekbone (zygoma) instead of the jaw for patients with severe bone loss. Rarely needed; reserved for extreme cases.

We recommend All-on-4 unless your bone structure specifically indicates otherwise.

Candidacy for All-on-4

Ideal candidates:

• Missing all or most teeth in one or both arches
• Adequate jawbone height/density (assessed via CBCT)
• Ages 18+ (jawbone fully developed)
• Committed to excellent oral hygiene
• Non-smokers or willing to quit during healing
• Reasonable overall health

Possible candidates requiring additional planning:

• Severe bone loss: bone grafting may precede All-on-4, adding 3-4 months
• Uncontrolled diabetes or medical conditions: we coordinate with your physicians
• Smokers: healing is slower, success rates drop; we strongly recommend quitting

Very rarely, patients are advised against it: If your medical status or bone structure is extremely compromised, we may recommend dentures or further evaluation. However, most people seeking All-on-4 are candidates.

The Temporary vs. Permanent Prosthesis

Temporary Prosthesis (Immediate): Fabricated before surgery, screw-retained to the implants. Allows immediate function, eating soft foods, speaking clearly, and regaining confidence. It’s beautiful and functional but not as refined as the permanent. Worn 3-6 months during osseointegration.

Permanent Prosthesis (Final, Lasting 20-30 Years): After osseointegration, fabricated to exacting specifications in our lab. Superior shade matching, ideal bite alignment, longevity-tested materials. Screw-retained or cemented (we recommend screw-retained for retrievability). This is your “forever” restoration.

Bone Loss: The Hidden Advantage of All-on-4

Dentures do not prevent bone loss. Your jawbone resorbs because there’s no stimulation from tooth roots (dentures sit on top of bone, not in it). Over time, denture wearers can experience significant jawbone loss, leading to:

• Dentures that fit worse over time, requiring constant adjustments
• A sunken, prematurely aged facial appearance
• Progressive loss of lower face definition

All-on-4 implants reverse this. Implants stimulate bone directly, halting loss and even triggering modest bone regeneration in some cases. Your jawbone stays strong and your face maintains its youthful structure—a significant difference over 20-30 years.

All-on-4 Care and Longevity

Daily care (just like natural teeth):

• Brush twice daily with soft-bristled toothbrush
• Floss daily (special floss for prosthetics)
• Rinse after meals

Professional care:

• Cleanings and exams every 6 months
• Annual full imaging to monitor bone

Avoid:

• Smoking (accelerates bone loss around implants)
• Chewing on hard objects (ice, hard candy, pens)
• Extreme contact sports (rare risk of implant trauma)

Expected lifespan:

• Implants themselves: 30-40+ years or lifetime
• Prosthesis (teeth): 15-25 years, then may need replacement due to normal wear
• Many All-on-4 patients never need replacement; others do once in their lifetime

Cost and Financing

All-on-4 includes surgical planning and CBCT imaging, four Straumann implants, immediate temporary prosthesis, final permanent restoration, and first year of post-operative care. When considering long-term value, All-on-4 is often more economical than dentures over a lifetime since dentures require frequent replacements every 5-8 years, adjustments, and ongoing maintenance costs. We offer financing through Cherry, CareCredit, and Sunbit with flexible payment plans. Insurance may cover a percentage; we’ll verify your benefits. Contact us for a personalized cost estimate.
