If your dentist or oral surgeon has asked you to get a CBCT scan before your implant procedure, you are on the right track. CBCT imaging is now considered the standard of care for implant planning — not because it is required by regulation, but because it genuinely makes the procedure safer and more predictable.
This guide walks you through every step of the process, from the moment you receive your referral to the day of your surgery. By the end, you will know exactly what to expect and why each step matters.
Why your dentist referred you for a CBCT scan
A dental implant is a titanium fixture placed directly into your jawbone. To place it safely, your surgeon needs precise three-dimensional information about your bone — its height, width, density, and the exact location of structures like the inferior alveolar nerve and the maxillary sinus.
A standard X-ray or OPG cannot provide this. It shows a flat 2D shadow of your jaw. That is useful for many things, but not enough to safely plan where a titanium fixture will live in your bone for the next 20 years.
CBCT gives your surgeon a complete 3D map of your jaw. It is the difference between planning a building with architectural drawings versus a scale model you can examine from every angle.
Step-by-step: what happens from referral to surgery
Here is the complete journey from the moment you receive your referral to the day of your implant surgery.
1.Get a referral prescription
Your implantologist writes a prescription specifying the CBCT scan type and the implant sites they need imaged. Bring this with you.
2.Book your appointment
Book at Envision Denta Kasba (Rajdanga Main Road) or Behala (Jadu Colony). Walk-ins are welcome, but an appointment guarantees your time slot.
3.Arrive and get scanned
The CBCT scan takes 20 to 40 seconds. You stand comfortably while the machine rotates around your head. No injections, no needles, nothing inside your mouth.
4.Report prepared by specialist
An MDS-qualified oral and maxillofacial radiologist reviews your full 3D dataset and prepares a detailed written report annotated for treatment planning.
5.Receive report and DICOM files
Your report and the full DICOM dataset are shared digitally within 12-24 hours. You forward these directly to your implantologist.
6.Virtual implant planning
Your surgeon loads your DICOM files into planning software and virtually positions the implant before making a single incision.
7.Implant surgery
Surgery proceeds with a precise, data-driven plan. Your surgeon knows exactly where to place the implant, how deep, and at what angulation.
What your CBCT report includes
At Envision Denta, our CBCT reports for implant planning are prepared specifically for your treatment team — not generic radiology reports. Here is what every implant planning report covers:
- Available bone height at each planned implant site (measured in millimetres)
- Available bone width — critical for selecting the correct implant diameter
- Bone density classification at the implant site (Type I through Type IV)
- Exact distance from the alveolar crest to the inferior alveolar nerve canal
- Sinus floor position and residual bone height for upper jaw sites
- Any pathology at or near the implant site that needs attention before surgery
- Recommendations for implant dimensions and any need for augmentation
The report is written so that your implantologist can move directly into planning without having to re-interpret raw imaging data. Our goal is to reduce the cognitive load on your surgeon and give them a clean, decision-ready document.
What are DICOM files and what does your surgeon do with them?
DICOM stands for Digital Imaging and Communications in Medicine. It is the universal format for medical imaging data. When you receive your CBCT results from Envision Denta, you get two things: a written radiology report and a DICOM dataset.
The DICOM dataset is the raw 3D data from your scan — hundreds of cross-sectional images that together form a complete volumetric model of your jaw. Your surgeon loads this into dedicated implant planning software.
What planning software can open these files?
Our DICOM files are compatible with all major implant planning platforms in use by implantologists in Kolkata and across India:
- SimPlant (Dentsply Sirona)
- Nobel Clinician (Nobel Biocare)
- coDiagnostiX (Dental Wings / Straumann)
- Blue Sky Plan (Blue Sky Bio)
- Planmeca Romexis
- Any standard DICOM viewer for general review
What your surgeon does with the 3D data
Using your DICOM data, your implantologist can virtually place the implant in the software before making a single incision. They will position the implant at the correct angulation and depth, confirm the safe distance from the nerve, and generate a surgical guide if needed. The result is a surgery that proceeds according to a precise, data-driven plan rather than intraoperative estimation.
How to prepare for your CBCT scan
Good news: a CBCT scan requires almost no preparation. There is nothing to eat or drink restrictions, no fasting, no special clothing requirements. A few practical things to note:
- Remove metal jewellery near your head and neck before the scan — earrings, necklaces, and hair accessories can cause artefacts
- If you wear hearing aids, remove them before the scan
- Bring your dentist's referral prescription — this tells our radiographers exactly which area to scan
- Inform us if you are pregnant or think you might be
- Inform us of any claustrophobia — the CBCT machine is open and most patients find it comfortable, but we can explain the process fully before you begin
Expect to spend about 20 to 30 minutes at the centre in total — the scan itself takes 20 to 40 seconds, and the rest is registration and positioning.
After the scan: what your surgeon does with the results
Once you receive your report and DICOM files, the next step is a pre-surgical consultation with your implantologist. At that appointment, they will review the report annotations and load your DICOM data into planning software.
Based on what the CBCT shows, your surgeon may:
- Confirm that sufficient bone is available and proceed directly to implant placement
- Recommend a bone grafting or sinus augmentation procedure before the implant, if bone volume is inadequate
- Adjust the planned implant size, length, or angulation based on the 3D anatomy
- Design a surgical guide (a physical template) for precise placement during surgery
- Identify any pre-existing pathology that needs to be treated first
All of these decisions are made before you are in the surgical chair. That is the entire point of the pre-surgical CBCT — to eliminate surprises and give you and your surgeon confidence that the procedure is planned correctly.
