Frequently Asked Questions

Our core services include:

• Teeth-supported, mucosa-supported, and bone-supported surgical guides

• Stackable surgical guide systems

• Surgical guides for crown lengthening procedures

• Guides for apicoectomy, sinus lifting, bone harvesting , and PTFE CARRIER for Guided Bone Regeneration 

• Customized zirconia and titanium membranes

• All-on-X implant planning and prosthetic design

• Digital Smile Design

To begin designing your surgical guide, we typically require:

• DICOM files (CBCT scan)

• STL files (intraoral scan or model scan)

• Implant system details

If you're unsure about file preparation, we’ll guide you step-by-step.

The double-scan protocol is a digital planning method used in fully edentulous patients to achieve prosthetically driven implant positioning with high positional accuracy.

It allows precise correlation between:

• The patient’s anatomical structures

• The intended prosthetic outcome

Clinical Overview

The protocol typically involves:

1. CBCT scan of the patient wearing a radiographic denture (scanning prosthesis)

2. Separate scan of the denture alone (CBCT or surface scan)

The two datasets are digitally aligned using radiopaque reference markers to accurately position implants according to the planned restoration.

For optimal alignment accuracy, the denture or scanning prosthesis should:

• Be well-fitting and stable (no mobility during scan)

• Contain 6–8 evenly distributed radiopaque markers (e.g., gutta-percha or composite markers)

• Have markers placed in non-linear, asymmetrical distribution to improve software matching

• Avoid metal components that may create artifacts

• Be fully seated during patient CBCT acquisition

Stability during scanning is critical.

Scan Requirements

Required:

• Patient CBCT (DICOM) with radiographic denture in full seating position

• Clear visualization of radiopaque markers

For the denture scan, you may choose one of the following:

Option A — Denture CBCT (DICOM)

• CBCT scan of the denture alone

• Must clearly capture all radiopaque markers

Option B — 360° Surface Scan of the Denture (STL)

• High-resolution extraoral or lab scanner

• Complete 360° capture including intaglio surface

• No missing data areas

• Markers clearly visible

A high-quality 360° STL surface scan is often preferred over denture CBCT due to reduced artifact and improved surface accuracy.

Important Considerations

• The prosthesis used in the scan must represent the intended restorative design (vertical dimension, occlusion, tooth position).

• Any change in prosthetic design after planning may require re-planning.

• The clinician remains responsible for verifying prosthetic parameters prior to approval.

Standard turnaround time:

• 24–48 hours for most single-unit cases

• 2–4 days for full-arch or complex cases
