What is the All-on-4® concept?
The All-on-4® concept is a well-established treatment protocol designed for the benefit of patients. This approach involves the placement of four dental implants in the upper or lower jaw to support a fixed dental prosthesis. In most cases, this procedure can be performed without the need for bone grafting.
It is essential to gather all necessary information before considering this treatment. Consult your dentist to obtain detailed information and determine whether this option is suitable for your situation.
Zygomatic implant
Another alternative to avoid bone grafting in most cases!
Zygomatic implants are used for patients with severe bone loss in the upper jaw (maxilla). As the name suggests, these implants are anchored in the zygomatic bone, also known as the cheekbone or malar bone, located near the maxillary sinuses.
If the patient is a good candidate, zygomatic implants can allow for the placement of a fixed implant-supported prosthesis, providing a stable and functional option despite significant bone loss in the maxilla.

Process toward the All-on-4® treatment concept
Step 1
Your first meeting with Dr. Carbery and his team
- Meet with the dentist to assess your oral health.
- Discuss your needs, expectations, and medical history.
Step 3
Treatment planning
- Develop a personalized plan based on your oral health and expectations.
- Present the treatment steps, timeline, expected results, and obtain informed consent.
Step 4
Surgical procedure
- Follow the established protocol, which involves placing four implants in the jaw under local anesthesia.
- Depending on your case, a fixed temporary prosthesis may be placed immediately or within a few days, allowing you to regain dental function quickly.
Step 5
Healing period
- The osseointegration phase (fusion of the implants with the bone) varies for each patient and typically takes several months. This will be evaluated by the dentist.
- Possible adjustments may be made to ensure patient comfort and the stability of the temporary prosthesis.
Step 6
Placement of the final implant-supported prosthesis
- Based on the patient’s choice, the temporary prosthesis is replaced with a permanent one (zirconia or acrylic), designed for durability, aesthetics, and functionality.
Step 7
Follow-up and maintenance
- Regular check-ups to monitor oral health and implant condition.
- Hygiene and maintenance advice to extend the lifespan of your dental prosthesis and implants.
