A full-arch restoration typically requires 4 to 6 dental implants per arch. The number depends on factors like bone density, jaw structure, and the chosen implant system.

Implant Options for Full-Arch Restoration

🦷 All-on-4 – Uses four implants for a cost-effective and efficient solution.
🦷 All-on-6 – Uses six implants for added stability and strength.
🦷 Implant-Supported Dentures – Can require 4 to 8 implants for removable dentures.

Factors Affecting the Number of Implants

Bone Density – Stronger bone may need fewer implants, while weaker bone may require more.
Jaw Size & Shape – A larger jaw may benefit from additional implants.
Patient’s Bite Force – Higher chewing pressure may require extra support.
Type of Prosthetic – Fixed bridges may need more implants than removable dentures.

Procedure Overview

1️⃣ Consultation – The dentist assesses bone health and plans implant placement.
2️⃣ Implant Surgery – 4 to 6 implants are placed strategically in the jawbone.
3️⃣ Healing Phase – The implants integrate with the bone (osseointegration).
4️⃣ Final Restoration – A custom bridge or denture is secured to the implants.

FAQs

Can fewer than 4 implants be used?
🗸 In rare cases, mini implants may be used, but they offer less stability.

Are more implants always better?
🗸 Not necessarily—proper placement is more important than quantity.

What happens if I don’t have enough bone?
🗸 Bone grafting may be needed to support the implants.
