The Straumann All-on-4 protocol fundamentally changed the treatment of full edentulism. With just four implants, an entire jaw can be restored with a fixed prosthesis — significantly reducing cost, surgical complexity and recovery time.
What Is Immediate Loading?
In the traditional protocol, 3–6 months are spent waiting for osseointegration before the prosthesis is made. In the immediate loading protocol, a temporary prosthesis is attached on the day of surgery. The patient leaves the clinic with fixed teeth the same day.
The Straumann BLX System
The Straumann BLX implant was specifically optimized for immediate loading. Its convergent design is engineered to achieve high primary stability (insertion torque) at the moment of placement — a prerequisite for same-day loading.
The Role of Digital Planning
In All-on-4, digital planning is not an advantage but a necessity. The correct angle of four implants (the two posterior implants are typically tilted 30–45°) directly determines the quality and load distribution of the fixed prosthesis. Without CBCT analysis this calculation cannot be made accurately. In 3Shape Implant Studio each position is virtually determined; the surgical guide executes the plan precisely.
Conclusion
The combination of Straumann All-on-4 and digital planning delivers the highest effectiveness ratio in full-arch rehabilitation. The patient leaves with a same-day fixed prosthesis, and the long-term outcome is built on the foundation of precise digital planning.
