There is no responsible one-price answer for All-on-4 treatment before an examination and treatment plan. A full-arch estimate may include imaging, extractions, bone procedures, anesthesia or sedation, implant surgery, temporary teeth, the definitive prosthesis, follow-up, and maintenance. Ontario patients should compare written estimates line by line rather than comparing only the advertised starting price.
What does "All-on-4" mean?
All-on-4 commonly refers to a fixed complete-arch dental prosthesis supported by four implants, often with angled posterior implants. It is one full-arch approach rather than a universal product or guarantee. A clinician may recommend a different number or arrangement of implants based on available bone, anatomy, bite forces, health, and the proposed restoration.
The decision should begin with whether remaining teeth can or should be preserved. Teeth should not be removed simply to fit a branded treatment concept without a diagnosis and discussion of tooth-preserving and removable alternatives.
Why do full-arch quotes differ?
Two estimates can describe very different treatment. Ask whether each quote includes:
- Examination, diagnostic records, and three-dimensional imaging when indicated
- Extractions and management of infection
- Bone grafting or other site-development procedures
- Anesthesia or sedation and who provides it
- Implant components and the planned number of implants
- A temporary removable or fixed prosthesis
- The definitive prosthesis, its material, and laboratory fees
- Adjustments during healing
- Hygiene instruction and professional maintenance
- Repairs, relines, replacement components, or remake exclusions
A low advertised figure may exclude parts of treatment that appear later. A higher figure may include services that another quote lists separately. Request the diagnosis, procedure sequence, included components, and exclusions in writing.
Does everyone receive fixed teeth on surgery day?
No. Some patients may receive an immediate provisional prosthesis when implant stability, anatomy, health, and the treatment plan allow it. Others need a removable temporary restoration or a different healing sequence. "Teeth in a day" should not be presented as a guarantee.
What risks and maintenance requirements should be discussed?
The U.S. Food and Drug Administration lists possible implant complications including infection, delayed healing, injury to nearby structures, nerve or sinus complications, loosening, and implant failure. Full-arch prostheses can also wear, fracture, loosen, affect speech or bite adaptation, and require repair or replacement.
Patients must be able to clean beneath the prosthesis and attend professional maintenance. Smoking, uncontrolled medical conditions, active gum disease, hygiene limitations, and some medications may affect healing or long-term risk. Published group outcomes cannot predict an individual result.
What alternatives should be compared?
Depending on the diagnosis, alternatives may include preserving and restoring selected teeth, a conventional removable denture, an implant-retained removable overdenture, or another fixed implant design. Each option differs in surgery, cleaning, repairability, stability, cost, and future maintenance.
How should insurance and financing be evaluated?
Dental benefits and exclusions vary by plan. Patients should ask the office for the proposed procedure codes and a written estimate, then verify benefits directly with the insurer. An estimate of benefits is not a guarantee of payment. Financing terms should be reviewed for interest rate, promotional-period rules, fees, total repayment, and consequences of a missed payment.
Where can Ontario patients request an evaluation?
Ontario patients may request a full-arch evaluation at Advanced Dentistry's Pomona office. The evaluation should determine whether implants are appropriate, which alternatives should be considered, and what the individualized estimate includes. Review the practice's All-on-4 treatment information, dental implant information, and Dr. Nabeel Cajee's profile, or request an evaluation.
Frequently Asked Questions
Is All-on-4 always supported by exactly four implants?
The named concept uses four implants, but a clinician may recommend another number or configuration based on anatomy, bone, bite forces, and the restorative plan.
Is a same-day fixed bridge guaranteed?
No. An immediate provisional prosthesis depends on implant stability, surgical findings, health, and the treatment plan.
Can the final cost be confirmed over the phone?
Usually not. A diagnosis, appropriate records, and a written plan are needed to determine the procedures and components required.
Do full-arch implants require ongoing maintenance?
Yes. Daily cleaning beneath the prosthesis, professional maintenance, and monitoring of implants, tissues, bite, and components remain necessary.
