Overview
Guided implant surgery uses three pieces of technology in sequence: a cone-beam CT (CBCT) of the jaw, an intraoral or model scan of the teeth, and planning software that aligns the two so the implant can be placed in the position dictated by the final tooth rather than by what feels easy with a freehand drill. The plan is converted into a 3D-printed surgical guide that constrains the drills to the planned position.
Where guides change outcomes
- Aesthetic zone single implants — sub-millimetre angulation matters for emergence.
- Posterior maxilla near the sinus — knowing exactly how much bone you have prevents perforation.
- Posterior mandible near the inferior alveolar nerve — guides reduce the risk of nerve injury.
- Full-arch flapless surgery — guides make this approach realistic.
- Less experienced surgeons benefit more than highly experienced ones.
What guides don't do
A guide does not improve poor case selection, does not preserve the buccal plate during extraction, and does not improve a surgeon's hands. Mucosa-supported guides can flex (sub-millimetre deviation is common in pooled data), so guides are an aid, not a substitute for clinical judgement.
Typical workflow
- CBCT of the jaws and intraoral scan or stone model scan.
- Data merged in implant planning software.
- Implant position planned from the final crown backwards ("crown-down" or "prosthetically driven").
- Surgical guide designed and 3D printed (1–2 weeks lead time).
- Guide used at surgery to drill at the planned position, angle, and depth.
