If you are missing most or all of your teeth, you deserve a solution that looks natural, feels comfortable, and lasts for years. I am Dr. Shahdad Arami, DDS, and here at Northridge Dental Group, I help patients every day who are looking for a permanent way to restore their smile. One of the most transformative treatments I offer is all on 4 dental implants. This procedure gives you a full arch of beautiful teeth supported by just four strategically placed implants. In this guide, I will walk you through everything you need to know — from how the procedure works to what recovery looks like and why so many patients in Northridge and surrounding communities are choosing this option.
What Are All-on-4 Dental Implants?
All-on-4 dental implants are a modern tooth replacement system. The concept is straightforward. A dentist places four titanium implant posts into your jawbone. These posts act as anchors. A full set of fixed prosthetic teeth is then attached to those four implants. The result is a complete arch of teeth — upper, lower, or both — that stays in place permanently.
Unlike traditional dentures that sit on top of your gums, an all on four implant bridge is screwed directly onto the implants. You do not remove them at night. You brush them like natural teeth. They do not slip, click, or cause sore spots. This is what makes the all-on-4 concept so popular among patients who want something that truly feels like their own teeth.
How the All-on-4 Procedure Works
The treatment starts with a thorough evaluation. I use advanced 3D imaging to study the shape and density of your jawbone. This helps me plan the exact placement of each implant. Two implants go toward the front of the jaw, where bone is naturally thicker. Two more implants go toward the back, but they are angled at up to 45 degrees. This angled placement is key. It allows us to use the available bone without the need for bone grafting in most cases.
On the day of surgery, I remove any remaining damaged teeth, place the four implants, and attach a temporary set of fixed teeth. You walk out of our Northridge office with a full smile on the same day. After a healing period of about three to six months, we replace the temporary teeth with your final, custom-crafted prosthetic arch.
Same-Day Teeth: Is It Really Possible?
Yes. One of the greatest advantages of the all-on-4 protocol is that you can receive a functional set of teeth on the same day as your implant surgery. This is sometimes called “teeth in a day.” The temporary prosthesis is carefully designed to look great and allow you to eat soft foods while your implants integrate with the bone. Patients are often amazed at how quickly they can smile with confidence again.
Who Is a Good Candidate for All-on-4 Implants?
Most adults who are missing all or most of their teeth in one or both arches are good candidates. This includes people who currently wear full dentures and want a permanent upgrade. It also includes patients whose remaining teeth are too damaged to save.
One of the biggest benefits of all on four dental implants is that many patients who have been told they do not have enough bone for traditional implants can still qualify. Because the back two implants are tilted, the procedure takes advantage of denser bone areas. This often eliminates the need for bone grafting, which saves time, money, and discomfort.
Patients with certain health conditions such as uncontrolled diabetes or heavy smoking may need to address those issues first. During your consultation at our office, I evaluate your overall health, bone quality, and goals to make sure this is the right path for you.
Benefits of Choosing All-on-4 Dental Implants
- Immediate results — You receive a full set of temporary teeth on the day of surgery.
- No bone grafting in most cases — The angled implant design works with your existing bone.
- Improved chewing ability — Fixed implant teeth restore up to 90% of natural biting force, according to research published by the International Journal of Oral & Maxillofacial Implants.
- Long-lasting solution — Studies show that all-on-4 implants have a cumulative survival rate of approximately 94.8% to 98% at the 10-year mark, as reported in a systematic review published in the Journal of Clinical Medicine.
- Natural appearance — The prosthetic arch is custom-made to match your facial structure and desired smile.
- Easy maintenance — You care for them much like natural teeth with brushing, flossing, and regular dental checkups.
- Preserved jawbone — Implants stimulate the bone and help prevent the bone loss that happens after tooth extraction.
All-on-4 vs. Traditional Dentures
Many of my patients in the San Fernando Valley area come to me after years of struggling with removable dentures. Dentures can slide around, make eating certain foods difficult, and cause irritation to the gums. Over time, bone loss beneath dentures changes the shape of the jaw, which means frequent adjustments and relining.
All on 4 implant supported teeth eliminate these problems. Because the prosthesis is anchored to implants embedded in the jawbone, it stays put. You can bite into an apple, chew steak, and laugh without worrying about your teeth moving. The stability and comfort are a life-changing upgrade from traditional dentures.
What to Expect During Recovery
After surgery, most patients experience mild to moderate swelling and discomfort for a few days. I prescribe appropriate medication and give you detailed aftercare instructions. For the first few weeks, you will stick to a soft food diet to protect the healing implants.
During the healing phase, your implants go through a process called osseointegration. This means the titanium posts fuse with your jawbone, creating a rock-solid foundation. This process usually takes three to six months. During this time, you will have follow-up visits at our Northridge dental office so I can monitor your progress and make sure everything is healing beautifully.
Once healing is complete, we take final impressions and design your permanent prosthetic arch. This final set of teeth is crafted from high-quality materials like zirconia or acrylic with a titanium framework. It is designed for durability, function, and a stunning appearance.
How Much Do All-on-4 Dental Implants Cost?
The cost of all-on-4 dental implants varies depending on factors like the materials used, the complexity of your case, and whether extractions or other preparatory work is needed. In general, the all-on-four procedure is more affordable than placing six to eight individual implants with separate crowns for each tooth. It is also a long-term investment that can save you money over time compared to the ongoing costs of denture adhesives, relines, and replacements.
During your consultation, we provide a transparent cost breakdown so you know exactly what to expect. We also discuss financing options to help make this treatment accessible. If you are exploring options for dental implants in Northridge, we are happy to walk you through the numbers.

Long-Term Care for Your All-on-4 Implants
Taking care of your all-on-four implant teeth is simple. Brush twice a day with a soft-bristle toothbrush. Use a water flosser or interdental brushes to clean around the implant connections beneath the prosthesis. Visit our office at least twice a year for professional cleanings and checkups. With proper care, your implants and prosthesis can last decades.
The American Dental Association emphasizes that dental implants are a well-established and effective treatment for replacing missing teeth, and regular professional maintenance is essential for long-term success.
Frequently Asked Questions
How long do all-on-4 dental implants last?
All-on-4 dental implants are designed to be a long-term solution. With proper oral hygiene and regular dental visits, the implants themselves can last a lifetime. The prosthetic arch typically lasts 15 to 20 years or longer before it may need replacement or refurbishment.
Is the all-on-4 procedure painful?
Most patients report less discomfort than they expected. The surgery is performed under local anesthesia, and sedation options are available for added comfort. Post-operative soreness is manageable with prescribed medication and usually subsides within a few days.
Can I get all-on-4 implants if I have bone loss in my jaw?
Yes, in many cases you can. The all-on-4 technique uses angled back implants to take advantage of denser bone areas, which often eliminates the need for bone grafting. During your consultation, your dentist will evaluate your bone with a 3D scan to confirm eligibility.
How much do all-on-4 dental implants cost in Northridge, California?
The cost varies based on individual needs, the materials chosen, and any additional procedures required. Generally, all-on-4 treatment is more cost-effective than replacing each tooth with an individual implant. We provide a detailed cost estimate during your consultation and offer financing options to help with affordability.
What can I eat after getting all-on-4 dental implants?
Immediately after surgery, you will eat soft foods for several weeks while your implants heal. Once your permanent prosthesis is placed and healing is complete, you can enjoy most of your favorite foods, including meats, vegetables, and crunchy items. Most patients find their chewing ability greatly improved compared to dentures.
