All-on-4 dental implants are a type of full-arch restoration used to replace
all teeth in the upper or lower jaw with strategically placed implants. This
technique is ideal for patients who have lost most or all of their teeth or
are dealing with significant dental issues like decay or bone loss. Here’s a
breakdown of the procedure:
1. Concept:
• The "All-on-4" refers to four implants placed in the jaw to support a full
prosthetic arch (a complete set of teeth).
• These implants serve as the foundation for a fixed (non-removable) dental
bridge.
2. How It Works:
• Implant Placement: Four titanium implants are surgically inserted into the
jawbone. Two implants are placed at the front of the jaw, while the other
two are placed at an angle towards the back, allowing for better stability.
• Immediate Load: In many cases, a temporary set of teeth can be placed on
the same day of surgery. This means that you walk out with functional teeth
immediately.
• Healing: Over several months, the implants will fuse with the jawbone
through a process called osseointegration, ensuring a strong and permanent
foundation.
• Final Prosthesis: Once healing is complete, a custom-made, permanent set
of teeth (usually made from acrylic or porcelain) is attached to the
implants.
3. Benefits:
• Cost-Effective: Fewer implants mean a lower cost compared to replacing
each tooth with a single implant.
• Stability: The angled placement of the posterior implants ensures more
stability and requires less bone volume, even in patients with bone loss.
• Quick Results: You can receive a full set of functional teeth on the day
of surgery.
• Permanent Solution: The prosthesis is fixed in place, so no need for daily
removal like traditional dentures.
4. Who Is a Candidate?:
• People missing most or all of their teeth in the upper or lower jaw.
• Patients with significant bone loss who might not be candidates for
traditional implants.
• Those seeking a stable, non-removable solution.
5. Post-Surgery Care:
• Like any surgical procedure, there is a recovery period where you’ll need
to follow your dentist’s instructions for care.
• Regular dental hygiene is necessary to maintain implant health, including
brushing and regular check-ups.
6. Comparison to Dentures:
• Unlike traditional dentures, All-on-4 implants are permanently fixed,
don’t require adhesive, and feel more natural since they are anchored in the
jawbone.
• No risk of slipping or shifting during eating or speaking, and they
provide better chewing efficiency.
