You don't have to keep working around missing teeth or holding a denture in place every time you eat.
All-on-4 uses four titanium implants, positioned at precise angles, to support an arch of 10 to 14 prosthetic teeth anchored permanently in the jawbone. Because of how the implants are angled, they access the densest available bone, which means most patients can skip the bone grafting traditional implant approaches often require.

- Teeth the same day: a functional temporary arch is in place before you leave surgery
- No adhesives, no slipping, no nightly removal: your teeth stay exactly where they belong
- Preserves the jawbone by restoring the stimulation that missing teeth no longer provide
What All-on-4 Dental Implants Actually Are
All-on-4 is built around a straightforward principle: four precisely placed implants, angled to access the densest available bone, can anchor an entire arch of teeth without the grafting procedures that some traditional dental implant treatments may require. Two posts anchor near the front of the arch, two angle toward the back, and together they support a fixed prosthesis that stays in place, functions with the bite force of natural teeth, and stimulates the jawbone the way tooth roots do.
Patients who have lived with a removable denture consistently describe the shift as more significant than they expected. That is the point.
All-on-4 Treatment Options for the Upper Arch, Lower Arch, or Full Mouth
All-on-4 dental implants can restore the upper jaw, lower jaw, or both arches, with each treated arch supported by its own planned set of implants. The right configuration depends on which teeth need replacement, available bone, bite forces, and the relationship between the upper and lower jaws. A clinical examination and 3D imaging are needed to determine whether All-on-4 or a customized All-on-X approach is more appropriate for your anatomy
| Treatment Area | Potential Treatment | How It Works | Clinical Considerations |
|---|---|---|---|
| Upper arch | Upper All-on-4 restoration | A planned set of implants supports a fixed arch of replacement teeth in the upper jaw. | Planning considers upper-jaw bone volume, sinus anatomy, bite position, and the condition of any remaining teeth. |
| Lower arch | Lower All-on-4 restoration | Four strategically positioned implants can support a fixed set of replacement teeth in the lower jaw. | Implant positioning must account for available bone, nerve anatomy, bite forces, and the opposing upper teeth. |
| Upper and lower arches | Full-mouth All-on-4 treatment | Both arches are restored within one coordinated treatment plan, with each arch supported by its own implants and fixed prosthesis. | Full-mouth treatment requires careful coordination of the bite, facial proportions, bone support, healing, and the design of both arches. |
| Cases requiring additional support | All-on-X dental implants | Four to six implants may be used to support a full arch when additional placement points are appropriate for the case. | The number and position of implants are determined from 3D imaging, bone anatomy, bite mechanics, and the support needed for a predictable restoration. |
How the All-on-4 Procedure Works
Consultation and Imaging
A full exam, digital X-rays, and 3D cone beam scans map your bone structure and determine the optimal implant placement. No treatment is scheduled until you have a complete picture of your case.
Treatment Planning
Using your scan data, the doctors design a precise implant placement blueprint and plan the final prosthesis, including color, shape, and fit, before surgery begins.
Implant Placement Surgery
Four implants are placed in a single two-hour appointment. Any remaining teeth are extracted first, sedation options are available, and a temporary prosthetic arch is attached before you leave with functional teeth.
Healing and Osseointegration
Over three to six months, the implants fuse with the jawbone. Most patients return to normal activity within a few days and follow a modified soft diet while the foundation sets.
Final Prosthesis
Once bone fusion is confirmed, the temporary arch is replaced with your permanent custom prosthesis, matched in color, shape, and proportion, and fixed permanently in place.
Who Is a Good Candidate for All-on-4
The ideal candidate has lost most or all of their teeth in one or both arches, is wearing a full removable denture that no longer functions the way it should, or has remaining teeth that cannot be saved. Because the angled implant positioning works with the bone density you already have, many patients who assumed they were out of options due to bone loss can still move forward, often without grafting. General health factors and any systemic conditions that affect healing are reviewed at your consultation at Advanced Dental Solutions, where you will leave with a clear, imaging-supported answer on whether All-on-4 is the right path and exactly what the process looks like for your anatomy.
Why Patients in Torrance Choose Advanced Dental Solutions for All-on-4
Dr. Shawna Omid is a former faculty member of the UCLA School of Dentistry, and for patients searching for all on 4 dental implants in Torrance, CA, that standard of care matters. Peer-reviewed data puts All-on-4 survival rates above 95%, and those results depend on the quality of planning before surgery, not during it. Dr. Mona Nejad and Dr. Matthieu Sullivan carry the same approach: review your imaging, explain the plan and the reasoning behind it, and give you an honest picture of the timeline and recovery before anything is scheduled. Most PPO insurance plans are accepted, and financing is available through CareCredit, Cherry, and the HFD Program.

Frequently Asked Questions About All-on-4 Dental Implants
Yes. All-on-4 is an immediate-load technique, meaning a functional temporary arch is attached to the implants on the day of surgery. You leave with a complete set of teeth. The permanent prosthesis replaces the temporary one after osseointegration is confirmed, typically three to six months later, but you are not without functional teeth at any point in the process.
During the osseointegration period, a soft food diet is recommended to protect the healing implants. Once the permanent prosthesis is in place, patients can eat a full diet with the same function they would expect from natural teeth. Very hard or sticky foods are still worth avoiding as a general maintenance habit, but the day-to-day experience is significantly closer to natural teeth than any removable alternative provides.
The titanium implant posts are designed to be a permanent solution, and clinical data supports survival rates above 95% long term with proper maintenance. The prosthetic arch may need to be refreshed after ten to fifteen years depending on wear, bite force, and hygiene habits. Patients who stay current with checkups and follow a consistent home care routine consistently get more from the prosthesis over time.
In most cases, no. The angled posterior implants access the denser bone that exists deeper in the jaw, which allows placement to move forward in patients who would not qualify for conventional vertical implants without grafting first. Some complex cases do require it, and that determination comes from your 3D scan during the consultation, not as a surprise the day of surgery.
All-on-4 uses exactly four implants to support a full arch prosthesis. All-on-X is the broader category that uses four to six implants, with the number and positioning adjusted for cases where bone anatomy or bite mechanics call for more support points. Both achieve full arch restoration; the distinction is in how many implants a specific case requires to do it well.
The jawbone beneath missing teeth begins to resorb over time because it no longer receives the stimulation it needs from biting and chewing forces. This is what causes the sunken facial appearance that develops with prolonged tooth loss. All-on-4 implants restore that stimulation directly through the titanium posts fused into the bone, which slows or halts further resorption. A removable denture rests on top of the gum tissue and cannot replicate this effect.
