Full-arch implant restorations have transformed the lives of edentulous patients. As the dental laboratory that fabricates these complex cases, we work closely with clinicians on both All-on-4 and All-on-6 protocols — and we have a uniquely practical perspective on how the two systems differ.
Biomechanical Considerations
All-on-4 uses four implants with two tilted posteriorly to maximize bone contact while avoiding the sinus. All-on-6 adds two more implants, distributing occlusal forces more evenly. From the lab side, this affects framework design: an All-on-6 can support a slightly more extensive posterior cantilever while maintaining acceptable stress distribution.
Framework Materials and Design
For full-arch implant bridges, we work with titanium, cobalt-chrome, and high-strength zirconia frameworks. The choice depends on the clinician's preference and the patient's occlusion. Titanium milled frameworks offer excellent biocompatibility and can be kept very thin. Zirconia frameworks offer outstanding aesthetics for patients with a high smile line.
Workflow and Turnaround
Both protocols require a multi-step workflow: verification jig, framework try-in, teeth arrangement approval, and final delivery. At Respect U Dental Lab, we guide clinicians step-by-step through this process. Proper communication of the vertical dimension of occlusion, inter-arch space, and smile design goals at the outset is critical.
Realistic Expectations for Patients
Both prostheses require professional cleaning and periodic checkups. The laboratory can provide a removable prosthesis for easy hygiene access, or a screw-retained fixed prosthesis for those who prefer the feel of fixed teeth. We offer both options and are happy to discuss which fits best for each clinical situation.
Whether you prefer All-on-4 or All-on-6, the success of the final restoration depends on close collaboration between the surgeon, the restorative dentist, and the laboratory. At Respect U Dental Lab, we are committed to being your partner throughout the entire process.
