3D Facial Scanning

A three-dimensional facial record can support dental planning and outcome assessment, with accuracy varying by scanning method.

[1]

The short answer

Three-dimensional facial scanning creates a digital record of facial form for dental diagnosis, treatment planning, and outcome assessment.

What is 3D facial scanning?

How facial scanning is used in dentistry
QuestionAnswer
What is captured?A three-dimensional digital record of facial form.[1]
Where is it used?Orthodontics, prosthodontics, and maxillofacial surgery.[1]

[1]

How can a dental team use it?

Dental studies have used facial scanning in orthodontics, prosthodontics, and maxillofacial surgery. It may be used for diagnosis, planning, and assessing an outcome after treatment.

[1][2]

How accurate is a facial scan?

Stereophotogrammetry, structured light, laser scanning, and mobile-device systems differ in accuracy and in how easily they connect with other digital records. Standard methods for combining facial scans with CBCT and intraoral scans remain underdeveloped.

Accuracy questions to ask
QuestionWhy it matters
Which system was used?Accuracy evidence may be tied to a particular system.[2]
What is the scan for?Interpretation depends on the intended clinical use.[1][2]

[2][1]

What other records might be combined with it?

Cone beam computed tomography and intraoral scans can be combined with a facial scan as part of a digital record set. The practical challenge is joining those records through a reliable method.

[1]

What does the scan mean for a patient?

For a patient, the scan supplies a three-dimensional record of facial form for planning or outcome assessment. Mobile scanning is used because it can be lower cost, accessible, and compatible with digital workflows.

[1]

Is 3D facial scanning safe?

Smartphone systems can capture detailed three-dimensional facial models, but their trueness and precision are less well established. Accuracy matters when a scan is integrated with other treatment records.

Frequently asked questions

Why might a facial scan be used with an intraoral scan or CBCT image?

They capture different digital records. A facial scan may be combined with intraoral scanning and cone beam computed tomography for diagnosis, planning, or outcome assessment.
