Prosthetically driven implant placement assisted by tablet-based augmented reality and tooth-supported registration:...

This technical procedure describes a tablet-based augmented reality (AR) workflow for prosthetically driven single-implant placement using tooth-supported marker registration and postoperative planned-to-placed three-dimensional (3D) verification.

Cone-beam computed tomography (CBCT), intraoral scans, and digital wax-up data were integrated to generate a prosthetically driven implant plan. The planning dataset was converted into an AR-compatible model and visualized on a tablet using the TreLab software. A tooth-supported AR marker guide was fabricated for marker-based registration. During surgery, the surgeon intermittently consulted the AR overlay as a visual reference to the planned implant axis and contextual anatomy. The drill was not tracked, and the osteotomy depth and implant placement were conventionally controlled. Postoperative CBCT was performed, and planned-to-placed deviations were calculated by best-fit superimposition using the remaining teeth as the reference region.

The workflow was completed without intraoperative complications or technical interruptions. Planned-to-placed verification demonstrated an angular deviation of 3.25°, a coronal 3D deviation of 0.68 mm, and an apical 3D deviation of 0.93 mm. These results demonstrate the technical feasibility of integrating prosthetically driven implant planning, tablet-based AR visualization, tooth-supported registration, and postoperative planned-to-placed verification into a single-implant clinical workflow. Because neither the drill nor the implant was dynamically tracked and the quantitative overlay error was not measured, the findings should be interpreted as preliminary technical verification rather than as evidence of navigational accuracy or clinical superiority.
