What does All-on-4 mean?
All-on-4 commonly describes a fixed complete-arch prosthesis supported by four dental implants. It is one treatment approach, not a universal product or guaranteed protocol. The recommended number and position of implants can change with bone anatomy, health, bite forces, the condition of remaining teeth, and the proposed restoration.
The first decision is whether remaining teeth can be predictably treated or should be removed. A complete-arch solution should be compared with tooth-preserving care, conventional implant options, and removable prostheses when appropriate. The Southern California full-arch implant guide explains those alternatives in more detail.
Why can full-arch estimates differ?
Two estimates may include different services. A lower figure may omit services charged later, so ask whether the written plan includes each of the items below.
| Item | Ask whether it is included | Why it changes the total |
|---|---|---|
| Examination, records, and imaging | Confirm whether the evaluation and any three-dimensional imaging are part of the estimate | Imaging is used to plan implant placement and may be listed separately |
| Extractions and treatment of infection | Ask whether removal of remaining teeth and infection management are included | The number of teeth and the presence of infection vary widely between patients |
| Bone grafting or site development | Ask whether grafting is anticipated and, if so, whether it is included | Some plans reduce grafting needs, but grafting can still be recommended after evaluation |
| Anesthesia or sedation | Ask who provides it and whether the fee is included | A separate qualified provider may bill separately |
| Implant components and planned number | Ask which components are planned and how many implants | Component choices and implant count differ between plans |
| Temporary prosthesis | Ask whether a removable or fixed temporary is included | An immediate fixed temporary is not possible for every patient |
| Definitive prosthesis and laboratory fees | Ask which material is planned and whether laboratory fees are included | Materials and laboratory work are a major part of the total |
| Adjustments and follow-up visits | Ask how many follow-up visits are included during healing | Adjustment visits are sometimes billed separately |
| Maintenance, repairs, and replacement parts | Ask what is excluded and how repairs are handled | Ongoing care is often outside the original estimate |
Patients should compare the diagnosis, sequence, included components, and exclusions, not only the total shown in an advertisement.
Can everyone receive fixed teeth on the day of surgery?
No. An immediate provisional prosthesis may be possible when implant stability, anatomy, health, and the treatment plan allow it. Other patients need a removable temporary prosthesis or a different healing sequence. Fixed teeth on the day of surgery should not be promised before evaluation.
What risks and maintenance needs should be discussed?
The U.S. Food and Drug Administration identifies possible implant complications including infection, delayed healing, injury to nearby tissues, nerve or sinus problems, loosening, and implant failure. A full-arch prosthesis can also wear, chip, fracture, loosen, affect speech or bite adaptation, and require repair or replacement.
Long-term care includes cleaning beneath the prosthesis and attending professional maintenance. Smoking, uncontrolled medical conditions, active gum disease, hygiene limitations, and some medications may affect healing or long-term risk. Published averages cannot predict an individual result.
What should Chino patients ask at a consultation?
Ask which alternatives were considered, who performs each stage, what temporary and definitive restorations are planned, what is included in the estimate, what could add cost, and what maintenance is expected.
At Advanced Dentistry & Orthodontics, Dr. Nabeel Cajee leads implant surgery, and three-dimensional imaging is used to plan implant placement. Full-arch care is offered at all three offices; Chino patients may request an evaluation at the Pomona office, where the surgeon and anesthesiologist coordinate full-arch care. Financing options include Cherry, CareCredit, and in-house plans; the terms should be reviewed in writing before treatment. Review the full-arch implant treatment page and the dental implant treatment page, or request an evaluation at the Pomona office.
Frequently Asked Questions
Is All-on-4 always supported by exactly four implants?
No. The appropriate number and arrangement depend on anatomy, health, bite forces, and the restoration plan.
Is bone grafting always avoided?
No. Some plans may reduce grafting needs, but grafting or another approach can still be recommended after evaluation.
Are repairs and maintenance included in the original estimate?
Not necessarily. Ask for written details about maintenance, repairs, replacement components, and exclusions.
Who performs the surgery and the anesthesia for a full-arch case?
Ask the office to name the surgeon and the anesthesia provider for each stage. At Advanced Dentistry & Orthodontics the surgeon and anesthesiologist travel to the patient's office for full-arch cases.
