Introduction
The All-on-X surgical sequence is often described in broad strokes online, skipping the deep procedural details that practitioners actually need before pursuing hands-on clinical training. This guide offers a practical overview of that sequence, focusing on how we approach the workflow within the HTDS curriculum.
1. Pre-Surgical Planning and Imaging
The process begins with a 3D CBCT scan to evaluate bone volume, map anatomical structures, and assess overall case suitability. This planning is strictly prosthetic-driven. In other words, the intended position of the final prosthesis dictates where the implants go, rather than letting the surgical site dictate the restorative outcome.
2. Extraction and Immediate Site Preparation
For patients who still have failing teeth, coordinating these extractions with immediate implant placement is a crucial part of the protocol. You must carefully assess the socket bone quality at the time of surgery. These real-time findings will heavily influence your intraoperative positioning decisions.
3. The Implant Placement Sequence
You will place the implants according to your pre-surgical plan, paying close attention to angulation. Angling the posterior implants allows you to engage maximum available bone while safely avoiding key anatomical structures, such as the maxillary sinus or the inferior alveolar nerve canal. Navigating these technical details is where hands-on training becomes essential, as sudden variations in bone density often require on-the-fly planning adjustments.
4. Provisional Prosthesis Delivery
Most All-on-X protocols call for delivering a provisional prosthesis on the day of surgery or shortly after. This gives the patient immediate function and aesthetics during the healing period. To pull this off, you need seamless coordination between the surgical and prosthetic phases of the procedure.
5. Healing, Follow-Up, and the Final Transition
After placement, the patient enters a healing period of several months to allow for osseointegration. Regular follow-up visits let you monitor tissue response and implant stability. Once healing is complete, you can begin fabricating and delivering the final, definitive prosthesis.
Frequently Asked Questions
Q: Is same-day loading a mandatory part of the All-on-X protocol?
A: While immediate loading is a major benefit of All-on-X, it relies entirely on achieving high primary stability during surgery. If you do not hit your target insertion torque values, you must pivot to a delayed loading approach.
Q: Does this overview replace hands-on surgical training?
A: No. This guide simply outlines the sequence and planning logic. You need supervised, hands-on training to develop the actual technical skill and tactile feedback required to perform this surgery safely.
Q: What imaging is required before starting an All-on-X case?
A: A CBCT scan is the absolute standard. You cannot safely plan implant angulation or evaluate bone volume for an All-on-X arch using 2D radiographs alone.
Q: How do you determine the exact implant angulation?
A: You plan these angles digitally before surgery based on the patient’s bone anatomy. However, you must always remain ready to refine these angles during the procedure based on tactile feedback and intraoperative findings.
