AI in implant planning and guided surgery

Aipedia, by the Apex broking team · Last reviewed 2026-10-27

Dentists can use AI to segment CBCT scans and propose implant positions, but they must personally verify nerve, sinus and bone measurements before relying on a guide. Implant injuries can be serious and permanent, so errors traced to an unchecked AI plan are hard to defend.

Part of: AI in Dentists

In short

Implant planning software uses AI to segment CBCT scans, trace the inferior alveolar canal, outline the sinus floor and propose implant size and position, which can then be exported to a printed surgical guide. IR(ME)R regulation 12(9) still requires a recorded clinical evaluation of each CBCT exposure. GDC standards 7.2 (competence), 6.3.1 (accountability) and Principle 3 (consent) apply in full. If segmentation misplaces the nerve canal, the guide can direct an implant into it. Implant work may be treated as higher risk by indemnifiers, and one defence organisation's published position excludes software defects and product liability.

How AI is used in implant planning

Guided implant surgery relies on planning software, and AI can now do more of the work. Tools automatically segment teeth, bone and soft tissue from a CBCT scan, trace the inferior alveolar canal and mental foramen, mark the sinus floor, and suggest an implant position, angle and size based on the planned restoration. The plan can be sent to a laboratory or in-house printer to make a surgical guide. In some workflows the scan, segmentation, plan and guide are all produced by an external service, and the surgeon receives a finished guide to approve.

Speed is the attraction. The risk is that automated segmentation looks precise on screen even when the scan quality, artefacts from existing restorations or unusual anatomy have misled it.

The duties that apply

IR(ME)R: under regulation 12(9) a clinical evaluation of the outcome of each exposure must be recorded. That includes the whole CBCT volume, not just the area the software planned around.
Competence: under the Standards for the Dental Team, 7.2 requires you to work within your knowledge, skills and competence, including the ability to interpret CBCT and plan without the software.
Accountability: 6.3.1 says you can delegate responsibility for a task but not the accountability. A plan or guide designed by a lab, service or algorithm becomes your responsibility once you use it.
Consent: Principle 3 requires valid consent covering all relevant options, risks and costs, including the specific risk of nerve or sinus injury in that patient.
Devices and law: standard 1.9 means checking the regulatory status of planning software and guides used clinically.

What can go wrong

Illustrative scenario: a dentist plans a lower molar implant using automatic canal tracing. Artefact from an adjacent restoration causes the software to place the canal higher than it is, and the proposed implant length leaves what appears to be a safe margin. The dentist approves the plan without checking the cross-sections, and the printed guide places the implant into the canal. The patient has persistent numbness of the lip and chin.

Similar risks arise with the sinus floor, thin buccal bone and guides that do not seat fully. Incidental findings elsewhere in the CBCT volume can also be missed if attention is only on the planned site.

How indemnity usually responds

A nerve or sinus injury claim is usually brought against the treating dentist as clinical negligence, and the question is whether a reasonably competent implant dentist would have identified the risk. Relying on automatic segmentation is unlikely to answer that on its own. Implant dentistry may be treated as higher-risk work by indemnifiers, and the GDC indemnity guidance requires cover appropriate to your scope of practice, so make sure your arrangement reflects implant work. One defence organisation's published position on AI excludes software defects and product liability, so a fault in the planning software or a guide is usually a matter for the supplier contract; see AI contract clauses and indemnities and AI exclusions in policies.

Practical controls

Check the nerve canal, foramen and sinus floor yourself on cross-sections, not just the 3D render.
Record your own CBCT evaluation of the whole volume.
Confirm safety margins and implant dimensions independently of the software's suggestion.
Check the guide fits and seats before drilling, and have a plan if it does not.
Discuss specific risks for that patient and record the discussion.
Keep the plan files, the version approved and any changes you made.

How Apex helps

Apex arranges indemnity for dentists, including those placing implants. A broker reviews whether your cover reflects implant work planned with AI and how software or guide failures would be treated.

Frequently asked

Can I rely on automatic nerve canal tracing?

Use it as a starting point, not an answer. Automatic tracing can be misled by artefact, scan quality or unusual anatomy. Check the canal on cross-sections yourself and record that you did, because the competence and accountability duties remain yours.

Who is responsible if a lab-designed guide is wrong?

The patient's claim is usually against the treating dentist, who approved and used the guide. Any recovery from the lab or software provider depends on contract terms and product liability law, which one defence organisation says needs reform for AI.

Does my indemnity cover implant work automatically?

Not necessarily. GDC indemnity guidance requires cover appropriate to your scope of practice, and implant work may be treated as higher risk. Tell your indemnifier or broker if you place implants and confirm it is included, subject to the terms.

Should I keep the AI plan files?

Yes. Keep the scan, the automated segmentation, the plan version you approved, any changes you made and the guide design. If a claim arises, those files show what the software proposed and what you checked, which is central to showing a human made the decision.
