Full-Arch Implant Reconstruction of Both Jaws, Planned and Placed with Surgical Guides
Both jaws rebuilt on dental implants. Each implant position was planned on the 3D scan against the final teeth, and printed surgical guides were used to place them there.
The Situation
Failing teeth in both jaws, with the patient wanting fixed teeth rather than dentures. A full-arch reconstruction replaces every tooth in an arch with a single bridge carried on four to six implants.
What Was Done
Every implant was planned in software on the cone-beam CT scan, against a digital design of the final teeth, so each one sits where the bite and the bridge need it. Printed surgical guides were seated on the jaw during surgery and directed each implant to its planned position and depth. On how closely guides hold to a plan, the systematic review and meta-analysis by Tahmaseb and colleagues in Clinical Oral Implants Research concluded that the accuracy of static computer-aided implant surgery falls within a clinically acceptable range in most clinical situations, while advising that a safety margin of at least two millimeters still be respected. A guide is an aid to placement, not a substitute for the margin.
The Result
Fixed teeth in both arches, made from a digital design of the final smile. The full-arch page explains the options, the sequence, and what the day of surgery is like.
