Comparative Evaluation of All on 4 versus All on 6 Implant Supported Full Arch Prostheses: A Review of Clinical Outcomes, Biomechanics, and Prosthetic Considerations

Key Points

• The aim is to evaluate the clinical outcomes and biomechanical differences between All-on-4 and All-on-6 implant protocols.
• Conducted a comparative review of existing literature on All-on-4 and All-on-6 techniques.
• Assessed implant survival rates, complications, and patient-centered outcomes.
• Analyzed biomechanical properties and prosthetic designs associated with each protocol.
• Both All-on-4 and All-on-6 protocols showed high success rates.
• All-on-6 demonstrated better stress distribution and support for prosthetics.
• All-on-6 is more favorable for patients with adequate bone volume.
