Impaction and TMJ cases need 3D. A panoramic radiograph guesses at depth.

A panoramic radiograph tells you a canine is impacted. It does not reliably tell you whether it sits buccal or palatal to the arch, how it relates to the roots of the neighboring lateral incisor, or whether resorption has already started — all decisions that change the surgical exposure and traction plan.

The same limitation applies to third molar assessment relative to the inferior alveolar nerve, TMJ evaluation before splint therapy, and any orthognathic case where skeletal asymmetry needs to be measured rather than estimated. CBCT resolves each of these — but the file still needs to reach the orthodontist's chair, not stay on a CD in an envelope.

CBCTHub opens the CBCT in the browser the imaging center already emailed a link for, so the 3D assessment happens at the consult, not a week later after the CD arrives.

What CBCTHub does for orthodontic diagnosis

Impacted tooth 3D localization

Determine whether an impacted canine or premolar is buccal or palatal, its angulation, and its proximity to adjacent roots using axial, panoramic and cross-sectional views side by side.

Third molar assessment

Evaluate impacted third molar depth and angulation relative to the inferior alveolar nerve canal and the second molar root before extraction referral.

TMJ and condyle evaluation

Scroll sagittal and coronal cross-sections through each condyle to compare position, cortical outline, and left-right symmetry.

Root proximity and resorption screening

Identify short or resorbed roots and interradicular proximity in three planes before deciding on mini-implant placement or extraction sequencing.

Orthognathic surgical planning cross-sections

Review the skeletal CBCT with the oral surgeon — ramus length, mandibular symmetry, and airway dimension — before finalizing a SARPE or orthognathic plan.

Airway and skeletal asymmetry review

Scroll sagittal slices through the oropharynx and compare left-right skeletal structures to flag findings that change treatment timing.

Common orthodontic workflows

Retained canine assessment

  1. 1.Open the CBCT and locate the retained canine on the panoramic reconstruction.
  2. 2.Scroll axial slices to determine buccal or palatal position.
  3. 3.Check the lateral incisor root for resorption on cross-section.
  4. 4.Measure angulation to plan exposure and traction direction.

Impacted third molar depth measurement

  1. 1.Scroll cross-sections at the level of the impacted molar.
  2. 2.Measure distance from the root apex to the IAN canal.
  3. 3.Check angulation relative to the second molar.
  4. 4.Share the finding with the oral surgeon before referral.

TMJ evaluation for splint therapy

  1. 1.Open sagittal cross-sections through each condyle.
  2. 2.Compare condylar position within the fossa on both sides.
  3. 3.Check cortical outline for flattening or erosion.
  4. 4.Document findings before starting or adjusting splint therapy.

Pre-surgical orthognathic case review

  1. 1.Open the CBCT alongside the treatment plan.
  2. 2.Measure ramus length and mandibular symmetry left to right.
  3. 3.Review airway dimension on sagittal slices.
  4. 4.Share the volume with the surgeon via link for joint case planning.

Panoramic radiograph vs. CBCT for impaction and TMJ

Desktop viewer vs. cloud collaboration: a desktop DICOM viewer keeps the CBCT on one office computer. CBCTHub keeps the same study accessible to the orthodontist, the oral surgeon, and the aligner lab from a single link — useful when a case needs more than one specialist to sign off.

Frequently asked questions

Can I localize an impacted canine in 3D?

Yes. Panoramic, axial and cross-sectional views side by side show whether the canine is buccal or palatal, its angulation, and whether it is resorbing the root of an adjacent incisor — the three findings that change the exposure and traction plan.

Does CBCTHub support cephalometric analysis?

You can place linear measurements and annotations on any slice or reconstructed view, including a generated lateral projection. Automated cephalometric landmark detection with a full tracing report is on the roadmap, not available today.

Can I evaluate the TMJ and condyle position?

Yes. Scroll sagittal and coronal cross-sections through each condyle to assess position within the fossa, cortical outline, and left-right symmetry — the standard read before splint therapy or further TMJ workup.

Is it useful for orthognathic surgical planning?

CBCTHub is used to review the skeletal CBCT before and during orthognathic planning — measuring asymmetry, ramus length, and airway dimension — and to share the volume with the oral surgeon. It does not perform automated surgical simulation or splint design.

Can I measure root proximity and resorption before appliance placement?

Yes. Cross-sections through the interradicular space show root proximity and resorbed apices in three planes, which is more reliable than estimating from a panoramic radiograph alone.

Can I share findings with the surgeon or the lab without them creating an account?

Yes. Generate a link and send it to the surgeon, the aligner lab, or a colleague for a second opinion. It opens directly in their browser, no login required.
