Understanding the All-on-4 Full-Arch Restoration
The all on 4 procedure is a dental implant technique for restoring a full upper or lower arch of teeth with just four titanium implants. This approach provides patients with a fixed, natural-looking prosthesis, often on the same day as surgery, by strategically utilizing the patient's available bone.
First performed in 1998, this treatment concept is built on the principle of osseointegration—the process where bone fuses with titanium. It has a long-term success rate of up to 98%.
How the All-on-4 Procedure Works:
The technique uses four strategically placed implants: two in the front of the jaw and two in the back, angled up to 45 degrees. This angulation maximizes contact with existing bone and avoids vital structures like sinuses and nerves. These four implants provide a stable foundation for a full-arch bridge.
Key advantages include:
- Immediate results - Leave the office with functional teeth on surgery day.
- Uses existing bone - The technique is designed to work with your available jawbone.
- High success rate - Up to 98% implant survival.
- Long-lasting - Implants can last for decades.
- An efficient solution - Restores a full arch with only four implants.

Ideal Candidates for All-on-4
The all on 4 procedure is designed for individuals who:
- Are missing all or most of their teeth.
- Have a failing dentition requiring full extraction.
- Are currently using removable prosthetics and are seeking a stable, permanent solution.
A key advantage is its suitability for patients with some bone loss, as the angled implants can use existing dense bone. Ideal candidates should be in good general health and committed to maintaining excellent oral hygiene. A thorough assessment, including a 3D scan, is crucial to confirm candidacy.

The Superiority of a Fixed Solution
The all on 4 procedure provides a permanent, fixed solution. The implants are anchored directly to the jawbone, offering unparalleled stability and helping to preserve your natural facial structure. This allows you to eat, speak, and smile with total confidence.
Key benefits of this fixed approach include:
- Excellent Stability: Your new teeth are securely fixed to the jawbone.
- Improved Bone Health: Implants stimulate the jawbone, which helps prevent the bone resorption that occurs with missing teeth.
- Full Dietary Freedom: After healing, you can enjoy all your favorite foods without restriction.
- Easy Maintenance: You can brush and floss your new teeth just like natural ones.
- Enhanced Comfort: The prosthesis feels natural and does not cover the roof of your mouth, enhancing taste and sensation.
In short, the all on 4 procedure offers a secure, comfortable, and healthy alternative to the daily hassles and long-term problems associated with removable tooth replacement options.
The All-on-4 Procedure: A Step-by-Step Guide
The journey to a new smile with the all on 4 procedure at UNO DENTAL SAN FRANCISCO is a refined process focused on comfort, safety, and predictable results. Thanks to advanced digital planning, many patients leave with a beautiful, functional smile on the same day as their surgery. The process unfolds in four main stages.
Step 1: Initial Consultation and Advanced Planning
Your journey begins with a comprehensive consultation to discuss your goals and review your health history. We perform a thorough oral exam and take a 3D Cone Beam Computed Tomography (CBCT) scan. This detailed imaging allows us to view your jawbone, nerves, and sinuses in three dimensions, ensuring precise and safe implant placement. Using this data, we create a personalized treatment plan, digitally design your new smile, and discuss sedation options to ensure your complete comfort. Learn more about our same-day solutions here: Same Day Dental Implants.
Step 2: The Day of the All-on-4 Procedure
On surgery day, your comfort is our priority. We will administer your chosen sedation, often IV sedation (twilight sleep), to help you relax. The procedure begins with gently removing any remaining failing teeth. We then prepare the jawbone and place the four titanium implants with precision: two straight implants in the front and two angled up to 45 degrees in the back. This angulation is designed to maximize contact with your existing bone. Finally, we attach connectors called abutments to the implants, which will secure your new teeth. The surgery for a single arch typically takes about two hours.
Step 3: Receiving Your Temporary Prosthesis
This is the most exciting part for many patients. On the same day as your surgery, we attach a custom-made, temporary bridge to the abutments. This concept of immediate function means you walk out of our office with a complete, aesthetically pleasing smile. We check your bite and make adjustments for comfort and a natural look. You can speak and smile with confidence right away, though you will need to follow a soft food diet initially.
Step 4: Healing and Final Restoration
A healing period of 3 to 6 months follows, during which osseointegration occurs—your jawbone fuses with the titanium implants, creating a solid foundation. We will monitor your progress through several follow-up appointments.
Once healing is complete, we craft your final, permanent bridge from highly durable and aesthetic materials. You can choose from options like Zirconia, known for its exceptional strength and natural look (lasting 15+ years), or acrylic over a titanium bar (lasting 5-7 years). This final restoration is custom-designed to fit perfectly and look beautiful, giving you a durable smile built to last for decades. Explore our Restorative Dentistry services to learn more.

Potential Risks and Cost Considerations
At UNO DENTAL SAN FRANCISCO, we believe in full transparency. While the all on 4 procedure has a patient satisfaction rate of around 95%, it's important to understand the potential risks and financial investment to make an informed decision.
Understanding Potential Risks
Although rare, potential complications can occur. Our meticulous planning and surgical expertise significantly minimize these risks.
- Implant Failure: In rare cases, an implant may not integrate with the bone due to infection or other health factors.
- Infection (Peri-implantitis): Similar to gum disease, this is an infection around the implant, usually preventable with proper oral hygiene.
- Nerve Damage: Advanced 3D CBCT imaging allows us to map nerve pathways precisely, making this complication extremely unlikely.
- Sinus Complications: The strategic angulation of upper-jaw implants is designed specifically to avoid the sinus cavity.
Our team's experience, combined with advanced technology, ensures your procedure is as safe and predictable as possible.
Cost Considerations for the All-on-4 Procedure
The all on 4 procedure is an investment in your long-term health and quality of life. As a solution that restores a full arch with only four implants and is designed to utilize existing bone, it represents a significant value.
The total cost is influenced by several factors:
- Prosthesis Material: High-end materials like Zirconia have a higher initial cost but offer superior durability and aesthetics compared to acrylic.
- Case Complexity: The specifics of your anatomy and the need for procedures like tooth extractions can affect the final price.
During your consultation, we provide a detailed, transparent cost breakdown. We also offer financing options to help make this life-changing treatment accessible. For a deeper dive into pricing, read our guide: How Much Do Dental Implants Cost? Complete Guide.
Frequently Asked Questions about the All-on-4 Procedure
Here are concise answers to some of the most common questions about the all on 4 procedure.
Is the All-on-4 procedure painful?
The surgery itself is not painful. We use local anesthesia and offer IV sedation (twilight sleep) to ensure you are completely comfortable and relaxed. Post-operative discomfort, swelling, and bruising are normal and can be managed effectively with prescribed medication for a few days. Most patients find the recovery easier than anticipated.
How long do All-on-4 implants last?
The titanium implants can last a lifetime with proper care, as they fuse with your jawbone. The lifespan of the teeth (prosthesis) depends on the material. An acrylic bridge typically lasts 5 to 7 years, while a premium Zirconia bridge can last 15 to 25 years or more. Good oral hygiene is key to longevity.
What can I eat after the All-on-4 procedure?
Initially, you will need to follow a soft diet for several weeks to protect the healing implants. This includes foods like smoothies, yogurt, and soft pasta. After the healing period and placement of your final prosthesis, there are no dietary restrictions. You will be able to eat all your favorite foods, including hard and crunchy items, with confidence.
