Why Scanning? The iTero System


More precise impressions the first time around ( no retakes)


The Challenge of PVS Impressions

Pulls & Tears

Bubbles & Voids

Distortion

Tray-Tooth Contact

Poor Tray Bond

Delamination

Temperature

Technique (DFU’s)

Time Sensitivity

Chemistry

Varying Shrinkage

Stone Model Pouring

Die Trimming Discrepancies

iTero – Parallel Confocal Imaging

• Cadent iTero features parallel confocal imaging,not conventional triangulation which utilizes laser and optical scanning to digitally capture the surface and contours of the tooth and gum structure.

• The iTero scanner captures 100,000 points of laser light in perfect focus at 300 focal depths of the tooth structure. These focal depth images are spaced approximately 50 microns apart.


Only iTero is 100% Powder Free Scanning

• iTero is the ONLY Intra-Oral Scanning System that does not require powdering for any type of scanning, on any type of restoration

• Powdering, Accent Frosting, Dusting….it’s all the same messy, expensive, time consuming procedure

• Lava COS, E4D, and Cerec all require some type of powdering procedure depending on the system an type of restoration

Example – Powdering with the Sirona Cerec System


Tooth Coating with Triangulation/ Sampling

• Triangulation/sampling scanners require the teeth to be coated with titanium oxyde to avoid light scattering.

• Hard to get to the undercuts with this technology


iTero vs. Sampling – Data Capture

VS.


Type of file obtained

• When you scan with Itero or a dental cast scanner , you get an STL file

• STL means stereolithographic file.

• STL are widely used for:- rapid prototyping

- computer-aided manufacturing. (CAD-CAM)

- STL files describe only the surface geometry of a three dimensional object without any representation of color, texture or other common CAD model attributes. (wikipedia)

You tube video of scanning


First use of Itero in Orthodontics

• Elimination of impressions

• Replacement of dental casts

- Great for multiple locations( accessible anywhere)

- No more storage

• Integration with conebeam CT technology




Use of 3D virtual models ( obtained by scanning)

• Treatment simulations

• Quick, easy, & precise measurement tools

• Occluded upper and lower study models


Treatment simulations


Second use: Scan for Invisalign

Eliminates PVS impressions and retakes. Your registration is always good.

Better patient and doctor experience

Quicker ClinCheck turnaround time Better fitting aligners


Based on 1,000+ scans:

• Time from submission to digital Treatment Plan = 2-3 days

• Virtually eliminates rejections

Eliminates PVS impressions

Better patient and doctor experience Quicker turnaround time Better fitting aligners

iTero – Why Scan for Invisalign?


Better fitting aligners

More detailed anatomy specially in the undercut areas allows for better fitting aligners.No tissue compression decreases theamount of black triangles

iTero – Why Scan for Invisalign?

7x Fewer Fit Issues Compared to PVS


Better fitting aligners!


Invisalign Experience

• With Itero, the fit of aligners is more precise. Potential for better and faster treatment….


Invisalign Experience

• Fit of aligners is awesome … Patients feel difference


Cadent and Invisalign

• Integration of Orthodontic Full-Arch iTero Impressions

• New 3-D Diagnosis and Treatment Management Applications Developed by Cadent for Invisalign Services

- Real-time Chair side Applications

- Case Assessment

- Case Planning

- Case Presentation

Third use; Indirect bracketing with Cadent technology

Virtual placement of brackets on 3D STL dental casts


Fabrication of precise custom transfer trays


Transfer to patien’t dentition


Fourth use: Fabrication of printed orthodontic appliances


3D virtual software


Production of a composite model


Printing of the 3D appliance with laser sintering


Retention Appliance


Conclusions

• 3D technology is advancing very rapidly in Oorthodontics

• Started in 1992 and is now almost mainstream

• Possibilities of CAD CAM impressions and appliances fabrications are just starting to emerge but will expand rapidly in the future.

• Far from perfect but getting much better everyday.
