Accuracy
Guided Surgery Narrows Deviation — It Does Not Erase It
Accuracy is a chain: the CBCT, the registration of the scan to it, how the guide seats, the tolerance in the sleeve, and the drill itself. Every link contributes. Guided placement is dramatically more predictable than freehand, but the honest way to plan it is to leave margin to the inferior alveolar canal, the sinus, and adjacent roots for that accumulated tolerance — not to plan to the last fraction of a millimeter and hope.

The tolerance chain: CBCT, registration, guide seat, sleeve, and drill — every link adds deviation, so margins are planned around the stack, not the ideal.

Restoratively driven positions: The positions the guide enforces come from the restorative plan, not from where the bone was easiest.
