Virtual Diagnostic Wax Up

Virtual Wax Up

Evolve the way you do wax up. Now, more than ever before, you can have complete control over the desired restorative treatment plan. You can have multiple options for treatment, allow the patients to see the planning, and also fabricate temporaries from the approved treatment plan.

Key advantages:

  1. Complete control over design and approval process through online webmeeting.
  2. Multiple options of treatment can be saved for patient approval prior to fabrication.
  3. Design is custom tailored to every patient.
  4. Capable of virtually simulating excursive movements, adding or subtracting vertical dimension, and even virtual crown lengthening.
  5. Delivery of suck-down appliances for prep-guiding, putty matrices if temporaries are to be made chair-side, or even pre-fabricated temporaries.

Frequently Asked Questions

Who are you?

nSequence®, under various names, have existed as a full-service dental lab in Reno, Nevada for several decades. In 2008, we began adding digital dental technology and evolved alongside the advancements to become what we are today: a complete solution for all things dental. We now feature a highly advanced digital dental laboratory operating seamlessly with our conventional lab.

In early 2014, nSequence® was acquired by National Dentex Corporation (NDX) and was put as the leading, cutting-edge technology lab within the network.

How do I submit a case?

Detailed case requirements may differ slightly depending on the type of case you are doing with us.

For CT guided surgical cases, follow this printable protocol: CT Guided Protocol

For diagnostic wax ups:

1) Upper and lower VPS impressions

2) Bite registration

3) Digital photographs in Kois-based photo series. Click here.

4) Submit case RX through our website top right menu. Send Us a Case –> Digital Wax Up Order

What kind of files do I need to send you?

Patient CT scans must be exported in multi-file DICOM format (this is a standardized file format for all CT scans in the dental and medical fields). There will be several hundred DICOM files for one patient, you must zip these files into one zipped file before sending to nSequence. You can also send us other files such as photos, notes, STL files, and whatever other files may be pertinent to the case.

How do I zip my files?

First, make sure you know where the DICOM files are stored. Then follow the instructions in this video below. Once complete, fill-out the online RX found in our Send Us a Case section, follow the instructions, and you will be prompted to submit the zipped file. 

Can you teach me about bad scans?

Our scan protocols have to be followed, which means proper scan appliances or bite registrations are taken. Our scan protocols also suggest 0.3voxel minimum with a 20-30 second duration settings. Outside of the protocol, the main issues we want to emphasize in scans are these:

1. Field of view

2. Patient movement during scan

Field of View

Please be sure to capture as much of the patient’s anatomy as possible. Capture at least 1/3 of sinus and nasal cavities, capture all visible teeth and bone on facial edge of anatomy, capture past posteriorly to 3rd molars if possible, and capture the chin. If your scanner can only capture one arch at a time, be sure to take 2 scans which described boundaries.

Patient Movement

Another critical problem is movement. Prior to releasing the patient from the CT scan, be sure to check for possible movement in the scan. If there is movement, that means surgical guides or bone reduction guides will not seat properly and therefore will be highly inaccurate and possibly harmful to the patient.

This can easily be avoided if the entire scan is reviewed by you to look for double lines on the images. Double lines or boundaries is a clear cut way to find bad scans. Click on examples:

Can I mail you the CD containing the scans?

Although we highly recommend uploading the data through our website, we understand that sometimes there are circumstances preventing you from uploading the data to us. We just ask that you make sure the disc contains the scan(s) in DICOM format, and it is indeed the most current scan you have to date.

Can I use intra-oral or digital impressions?

Absolutely. You can help expedite the process by exporting the files first to STL and also be sure to let us know what scanner you used. Call us if you need further assistance.

What scans and what kind of CT scanners do you work with?

We can work with any scanner that can output multi-file DICOM. Be sure to follow our protocol when scanning the patient.
