Load a jaw or dental CT study straight from your oral surgeon's office or hospital imaging portal and inspect it in the browser, slice by slice, without installing anything. The tool is built around the questions a dental CT actually answers “how much bone is left before the sinus floor”, “which direction is that third molar tipped”, “does this tooth have a vertical root fracture” and keeps every file on your own device the whole time. If your scan came from a cone-beam unit at a dental office, the dedicated free CBCT viewer is tuned for that smaller field of view; this page reads medical fan-beam CT of the jaw from a hospital or imaging center scanner.
Load Your Dental CTPoint the uploader at the CT export, ZIP archive included, and the parser splits the study into its axial acquisition plus any bone-kernel reconstruction of the maxilla and mandible.
Move through the thin axial slices, flip to sagittal or coronal reformats, and drop a ruler across the bone available above the mandibular canal or below the sinus floor.
Four models independently flag periapical lucency, canal proximity, or sinus involvement before Claude assembles the observations into one reviewable explanation.
A panoramic film flattens the jaw into a single two-dimensional strip, which hides exactly the depth information implant planning and impaction surgery depend on. A dental CT keeps the third dimension, so it can show how far an impacted lower third molar sits from the mandibular canal, how many millimeters of bone remain between a planned implant site and the inferior alveolar nerve or the maxillary sinus floor, and whether a root is angled toward or away from a neighboring structure. Oral surgeons lean on this depth data before extracting a wisdom tooth close to the canal, and implant planning software reads the same volume to pick an implant length and angle that avoids both the nerve and the sinus.
CT is also what settles questions a periapical film cannot answer on its own. A suspected vertical root fracture, a periapical lesion that does not resolve after root canal treatment, or a TMJ complaint with suspected condylar change all benefit from the cross-sectional detail a CT volume provides, because overlapping anatomy on a flat film can hide a fracture line or understate how far a lesion has eroded surrounding bone.
A medical dental CT is acquired as a helical volume of thin axial slices, then reconstructed on a sharp bone kernel that makes cortical margins, tooth roots, and canal walls crisp. Because the acquired voxels are isotropic, the same axial pass reformats into sagittal and coronal planes without any loss of detail, which is how the viewer follows a root or the mandibular canal along its full length instead of guessing at it from a single slice. Studies exported from Sirona, Planmeca, Carestream, and Vatech units all follow the same DICOM structure, so the viewer reads them the same way regardless of which unit produced the scan.
Decoding and rendering happen in the browser with the Canvas API. Nothing is pushed to a server; the study sits in IndexedDB until you clear it.
No desktop imaging software, no plugin. Open a tab, drop the CT export, and the axial stack loads inside Chrome, Firefox, Safari, or Edge.
Move through every slice with the slider or keyboard, then jump to the sagittal or coronal reformat when a root or canal is easier to trace along a different plane.
A window tuned for cortical and trabecular bone keeps tooth roots, the sinus floor, and the mandibular canal wall in sharp contrast on the same slice.
Draw a caliper from the alveolar crest down to the canal or sinus floor and read the distance in millimeters, the same unit an implant plan uses.
Step through consecutive slices to follow the mandibular canal past a wisdom tooth root or a planned implant site and see how close the two actually sit.
Dental CT reports lean on a handful of recurring phrases. “Periapical lesion” describes a dark area around a root tip that usually points to an infection tracking down from the pulp, and the report will note its size and how close it sits to nearby structures. “Canal proximity” or “contact with the inferior alveolar canal” refers to how near a tooth root or a planned implant site sits to the nerve canal, measured in millimeters, and drives whether a surgeon proceeds, repositions, or refers out. “Sinus pneumatization” describes the maxillary sinus expanding downward into the space where a molar root or implant would otherwise sit, which is why many upper posterior implant plans mention a sinus lift. Reports on a suspected fracture will describe a “vertical radiolucent line” through the root, distinct from the surrounding periodontal ligament space.
This page is built for medical fan-beam CT of the jaw, the kind ordered by an oral surgeon or hospital before a complex extraction, implant case, or when a lesion needs a closer look than a 2D film provides. If your scan instead came from a cone-beam CT (CBCT) unit at a dental office, which is common for routine implant planning and endodontic work-ups, the dedicated free CBCT viewer is tuned for that smaller field of view and voxel size. Both viewers share the same browser-based, nothing-uploaded approach; they simply cover different acquisition types, and this one does not resolve enamel-level detail or gum tissue the way a clinical exam and a periapical film do.
Yes. Loading and browsing a dental or jaw CT study costs nothing and has no slice limit. AI analysis of the study runs on credits, currently $10 per analysis session.
Yes, a caliper tool lets you draw from the alveolar crest down to the canal or sinus floor on the axial, sagittal, or coronal reformat and reads the distance in millimeters, the same way an implant plan is measured.
It can, but cone-beam studies are usually smaller and denser than hospital CT. For a CBCT export from a Sirona, Planmeca, Carestream, or Vatech unit, the dedicated free CBCT viewer is tuned specifically for that format.
Yes. Load the CT, switch to bone windowing, and step through the axial and coronal planes around the third molar root and the mandibular canal to see how much bone separates them.
The DICOM files are parsed and rendered entirely in your browser. Nothing is sent to a server, and closing the tab or clearing site data removes the study.
No. The viewer and its AI explanation describe what the images show in plain language; they do not replace a dentist or oral surgeon reading the study and examining you in person.

Dental CT is usually acquired as a true volumetric series, so it reconstructs well into sagittal and coronal reformats and, on supported devices, a rotating 3D surface render of the jaw. Canal position, root angulation, and available bone are easier to communicate on a rotating render than on a stack of flat slices, though sharpness still depends on the original slice thickness, spacing, and reconstruction kernel chosen at the scanner.
Learn how 3D DICOM viewing worksOn Analyze My Teeth, the viewer helps you review panoramic, bitewing, periapical, DICOM, and CBCT files for educational understanding before dentist, endodontist, oral surgery, or oral radiology review.
Review impacted wisdom teeth, implant planning anatomy, periapical lesions, root fracture concerns, jaw cysts, and TMJ bony findings as points to discuss with a dental professional.
Dental CT and CBCT files are easier to discuss when you know which tooth, root, canal, sinus, jaw structure, or panoramic X-ray finding is being shown.
AI explanations can organize visible imaging patterns, but they do not diagnose disease, replace clinical examination, or decide treatment. A dentist, oral surgeon, endodontist, or oral radiologist should confirm important findings.
Dental radiographs should be selected for a clinical reason and interpreted with the exam. Use this viewer to understand what is visible, then confirm tooth number, symptoms, radiation context, and treatment choices with a dental professional.
Often yes. A panoramic X-ray can show whether wisdom teeth are present, tilted, impacted, or close to nearby teeth. CBCT may be better when the dentist needs three-dimensional detail near the mandibular nerve, sinus, or roots.
Sometimes. Some root fractures are visible on periapical X-rays, but vertical or hairline fractures can be hidden by overlap, restorations, or projection angle. CBCT and an endodontic exam may be needed to confirm the concern.
CBCT is usually more useful when three-dimensional position changes care, such as impacted wisdom teeth, implant planning, root resorption, suspected fracture, periapical lesion extent, jaw cyst boundaries, or TMJ bone detail. Radiation exposure still needs a clinical reason.
A dentist should confirm the tooth number, symptoms, bite tests, pulp vitality, periodontal probing, previous treatment, image quality, and whether the imaging finding changes extraction, root canal, implant, or follow-up decisions.
AI cannot confirm pain source, pulp vitality, infection activity, cancer, biopsy need, or whether a tooth needs extraction, root canal treatment, implant surgery, or medication. It can miss subtle disease and can be fooled by artifacts.
Use the X-ray viewer for panoramic, bitewing, and periapical images. Use the CBCT or DICOM viewer when your dental office gave you a DICOM folder, ZIP export, or 3D volume.
