What Is All-on-4 and All-on-6 Implant Treatment?
All-on-4 implant treatment is a modern fixed prosthetic technique in which all missing teeth in a jaw are restored using just 4 specially angled implants; All-on-6 applies the same principle using 6 implants. In this method, strategically positioned implants provide the support for a fixed prosthesis placed across the entire jaw.
The All-on-4/6 system has largely replaced conventional removable dentures for individuals who have lost all their teeth, making a fixed, comfortable, and aesthetic smile possible in a significantly shorter timeframe.
What Is the Difference Between Conventional Implants and All-on-4?
While traditional methods require 8–12 implants to be placed across an entire jaw, the All-on-4 system achieves the same outcome with just 4 implants. The posterior implants are placed at a special angle (30–45°), allowing the available jawbone to be used with maximum efficiency.
This means:
- Bone grafting is generally not required
- The surgical process is shorter
- The overall treatment cost is more reasonable
- Recovery time is advantageous
All-on-6, on the other hand, provides greater support and more distributed force, making it the preferred choice for patients with sufficient bone density who desire a longer-lasting prosthesis.
Who Is All-on-4 / All-on-6 Suitable For?
This treatment is an ideal solution for patients in the following situations:
- Individuals who have lost all of their teeth
- Patients whose remaining teeth are about to be extracted
- Those who are unsatisfied with removable dentures
- Patients who want fixed teeth despite significant jawbone resorption
- Individuals who have previously been told they have “insufficient bone” for conventional implants
The All-on-4 Treatment Process, Step by Step
At Tower Dental Clinic, All-on-4 and All-on-6 treatments are carried out using CT-supported digital planning.
1. Digital Planning and Imaging A 3D CT scan of the patient’s jaw is taken, and the positions where the implants will be placed are determined with millimeter precision in a digital environment. This is a critical step that directly affects the success rate.
2. Surgical Procedure Under local anesthesia (with sedation if required), 4 or 6 implants are placed in a single session. The surgery takes approximately 2–3 hours.
3. Placement of the Temporary Fixed Prosthesis On the same day as implant placement, or within a few days, a temporary fixed prosthesis is fitted. The patient leaves the clinic with an aesthetic smile.
4. Healing Period (3–6 Months) During this period, the implants integrate with the jawbone. The patient continues with daily life wearing the temporary prosthesis.
5. Fabrication of the Permanent Prosthesis Once healing is complete, a digital impression is taken and a custom zirconia or hybrid permanent prosthesis is manufactured. Aesthetic form and shade are planned with great care.
6. Placement of the Permanent Prosthesis After trial fittings are completed, the permanent prosthesis is secured in place. The result: a natural-looking, fixed, and fully functional smile.
Advantages of All-on-4 Implant Treatment
Fixed Teeth on the Same Day The ability to leave the clinic with a temporary fixed prosthesis on the same day as surgery is the most frequently cited advantage.
Bone Grafting Is Generally Not Required The angled implant placement technique makes the most efficient use of the available bone tissue, reducing both time and cost.
Comfortable Chewing Function Thanks to the fixed structure — unlike removable dentures — nearly 90% of natural tooth chewing force is restored.
Natural Aesthetic Appearance Modern prosthetic design provides a natural look that harmonizes with facial features and lip support.
Improvement in Facial Aesthetics Lip collapse and the aged appearance that develop following tooth loss are largely restored with All-on-4.
Long-Lasting Solution With proper care, All-on-4 implants can last over 20 years.
How Long Does All-on-4 Treatment Take?
The total treatment process varies depending on the case:
- Initial surgery and temporary prosthesis: 1–3 days
- Osseointegration (healing and fusion) period: 3–6 months
- Permanent prosthesis completion time: 7–14 business days
For patients traveling from abroad, Tower Dental Clinic typically plans the entire process over two separate trips: the implants and temporary prosthesis are completed during the first visit, and the permanent prosthesis is finalized during the second.
Post-Treatment Care Recommendations
To extend the lifespan of All-on-4/6 implants, the following should be observed:
- Brush twice daily
- Use an interdental brush
- Clean between areas using a water flosser
- Professional check-up and cleaning every 6 months
- Limit tobacco use
- Use a night guard if bruxism (teeth grinding) is present
