OptiShade offers unmatched portability, affordability, and accuracy. With a repeatability of 0.2-0.4 ΔE, it aligns closely with spectrophotometric standards. It requires no subscription, protects user data, integrates with Matisse for ceramic layering, and communicates easily via iOS platforms. It is the only color-matching device compatible with the Matisse system for ceramic recipe prediction.
OptiShade is compatible with iPhones and iPads running iOS/iPadOS 17 or later. A comprehensive list of supported models from 2018–2024 is available in the last question. Note that Android devices are not supported due to the lack of a key functionality required by the OS system.
No. Android lacks critical system capabilities required for secure and accurate use of OptiShade. There are currently no plans to support Android. A dedicated iOS device is recommended.
Yes, OptiShade is compatible with iPad Pro (3rd gen and newer) and iPad Air (4th gen and newer), using a separately purchased USB-C cable. Earlier iPads use the Lightning cable included in the kit. The app interface is not optimized graphically for iPads, but all functionalities are fully operational. Make sure your iPad is capable of running iOS 17 or later.
No subscription is required. The OptiShade app is free to download from the App Store and offers unlimited measurements and image sharing.
Connection to Mac desktops or laptops is not possible due to the absence of essential functionalities and the unavailability of the Optishade app for computers.
The only way to read measures in a computer is through the Matisse Web App.
No. OptiShade functions fully offline. Internet access is only needed to share files or to interact with Matisse software.
All data is locally stored on your Apple device, encrypted, and never collected or shared by the app. Only you determine where and with whom data is shared.
Pricing varies by region based on shipping and import duties. OptiShade offers high repeatability and accuracy at a lower price point than other professional dental color-matching devices.
No, but it is highly recommended for dental technicians. Matisse provides precise ceramic recipes based on tooth measurements, restoration space, substrate color, and other parameters, drastically improving the accuracy and success of aesthetic restorations.
OptiShade is ideal for anterior teeth, and can also measure premolars and molars depending on access and clinician technique.
Yes. The app includes a continuously updated database for comparing results with standard commercial shade guides that can be dowloaded in the link https://www.styleitaliano.org/optishade/app/#color-database
Integration with Composhade and Matisse enables even more accurate matching through recipe generation.
No. The most precise measurements are taken at the center of the image. For optimal accuracy, capture one tooth per photo.
Yes. OptiShade integrates with the CompoShade App to suggest composite layering recipes using Enamel Plus HRi materials, accounting for thickness and translucency.
Applications include:
- Composite shade matching
- Ceramic layering and restoration
- Tooth bleaching monitoring (ΔE values)
- Color research and documentation
- Aging of materials
- Shade verification
- Denture tooth selection
- Quality control and education
OptiShade provides color readings with an error margin under 0.4 ΔE, aligned with professional spectrophotometers. Repeatability testing (over 10,000 measures) confirms consistent results across devices (0.2–0.4 ΔE94 within same device; 0.3–0.5 ΔE94 across different devices).
- Positioning: Requires consistent alignment; minimal training is sufficient
- Fogging: Patients should hold their breath during measurement
- External light: Avoid ambient light, sunlight, or dental unit lighting
- Contextual color: Gingiva and adjacent teeth can influence results
Monthly, under optimal conditions. Replace immediately if contaminated, scratched, or exposed to risk of cross-infection. Calibration caps are disposable and sold in packs of five.
No. OptiShade has built-in calibration and lighting, eliminating the need for external accessories. However, double-checking with traditional shade methods can add value in complex cases.
Not for measurements. OptiShade images are fully calibrated. However, Matisse software supports DSLR-based workflows using grey cards, though OptiShade is the preferred input method.
This is normal. Red or orange signifies that the measured tooth color is not close to any value of the shade guide you are comparing to. This does not indicate an error. Technicians and clinicians can interpret L*a*b* deviations to guide adjustments.
OptiShade is produced and distributed by Smile Line. Contact your local dealer (https://www.smileline.ch/en/dealers) or email mail@smileline.ch for direct inquiries.
No. The hard case is an optional accessory for travel convenience. It is not necessary for in-office use.

Q&A
FAQ
No. Unfortunately, Android lacks a functionality essential to the Optishade Styleitaliano (OS) system, and it cannot work safely in that environment. At the moment, there are no future plans to bring Optishade Styleitaliano (OS) to Android. It is suggested to have a dedicated iOS device for measuring.
Yes. The USB-C cable must be purchased separately for iPad Pro (3rd generation and later) and iPad Air (4th generation). Other iPads – including the iPad Pro (1st Generation) – use the Lightning cable you’ll find included in the Optishade Styleitaliano (OS) intro kit. Although the Optishade App is not graphically optimized for iPad, the functionalities are exactly the same.
No subscription is needed. You can download the Optishade App from the App Store for free. The number of measurements and image shares is unlimited.
The Optishade App can run on any Apple computer with Apple M1 chip and above (read and share function). Due to hardware restrictions, the device cannot be connected to laptops or desktop computers, directly, while files can be analyzed and shared on any device. New measurements can only be obtained with Optishade Styleitaliano (OS) connected to an iOS or iPADOS device, and these measurements can be analyzed on any of these devices and on M1 computers also.
Yes. Besides getting the precise and accurate L*a*b* coordinates, the main function of Optishade Styleitaliano (OS) is it allows comparison with ready made shade guides through a constantly updated database to compare the best match to commercial Shade Guide libraries. You can download and update colors for your library from www.styleitaliano.org/optishade/app
Note: Matching a Vita Classic or Vita 3D color can be extremely difficult with ceramics, as recreating the exact color of a shadeguide requires much more information than the nomenclature of the ceramic powder. The Matisse software (www.matisse.ai) provides also recipes to match Vita Shade guides.
No. As the most precise measure is taken at the center of the image frame, it is indicated to capture one tooth at a time.

You are the owner of your measurements and no one besides you (or whoever you choose) can read them. Optishade Styleitaliano doesn’t collect data from your device, or your patients. Everything is safely kept inside the Apple’s ecosystem, and only you choose how and where to share. Files are end-to-end encrypted.
No. With Optishade Styleitaliano you don’t need shade guides, DSRL cameras, grey cards, cross polarization filters or brackets. Optishade Styleitaliano already has all the functions needed for color matching.
Double shade matching, and any additional data, is always appreciated, as it provides extra info about tooth appearance and can sometimes make us aware about possible errors. Classical shade matching becomes less of a necessity with this kind of technology.
No, you can take measurements and use the OS app off-line. Just make sure your device is connected when sending or receiving files, or when using the Matisse software.
Price varies depending on your country (distance may be a reason of high shipping charges) and import taxes in your country. The price of Optishade Styleitaliano is lower than any existing dental color device offering the same level of repeatability and accuracy. Also, it is the only device compatible with Matisse.
While Optishade StyleItaliano and Matisse Software can work independently, Matisse nevertheless becomes a must-have for the dental technician to achieve a perfect shade matching with ceramics, thus eliminating remakes.
Matisse eliminates the dilemma in choosing the framework, ceramic powders, and enamels. With the Matisse customized recipes, the dental technician will be able to achieve an unbelievable result and leave both patient and dentist mesmerized!
The recipes generated include framework advice, a pure ceramic mixture recommendation, and an enamel guideline.
The customized recipes are calculated by taking 7 important parameters into consideration:
• The case indication
• The ceramic brand
• The framework brand
• The total amount of space available for the restoration
• The color of the preparation
• The color of the target tooth
• The enamel type
*Getting a recipe takes less than 30 seconds, upload the Optishade Styleitaliano photo, select the options and generate the recipe.

When used in optimal conditions, the calibration cap should be changed every month. When the white reference is touched, scratched, has visible contamination and if there is any chance of cross contamination, it has to be immediately replaced. Calibration caps are disposable, and they can be bought separately in packs of 5.
A sub-optimal state of the Calibration Cap may compromise the accuracy of the full system.
The hard case is an optional accessory designed for traveling with Optishade with a very compact solution. It is sold separately, as, If your intention is to use Optishade Styleitaliano in the office, you don’t need it.
OS fits in the palm of your hand, it has a convenient price, it has a repeatability of 0,4 DE or better, it needs no subscription for using the device, it doesn’t collect your data, it has color readings aligned with spectrophotometer, it compares the readings with common ready-made shade guides, it enables to send data via WhatsApp (and all other iOS communication channels) and receives App updates constantly. It is compatible with the Matisse software, which allows you to predict the mixing and layering of seamless ceramic crowns and veneers.
There are 4 main limits that can be easily controlled
a) Positioning: Optishade needs a perfect positioning in the mouth and on the model. If you are a first time user, it requires less than 30 minutes training to learn how to do a perfect measure. Find a thorough description in the users guide booklet and in the videos.
b) Fog susceptibility: patient needs to hold their breath while taking a measurement, if Optishade Styleitaliano captures fog, the measure will be ruined.
c) External light contamination: External light is a common enemy to almost any color matching system. Choose a position away from sunlight and windows. Close curtains, drapes and turn off intense light sources and the light from the dental chair unit, even if it is not pointing directly onto the working field. A light contaminated image is inaccurate.
d) Contextual Color: The tooth is measured in the mouth context, which means that includes the light reflections from the gums and neighbour teeth.

Optishade Styelitaliano is specifically designed for anterior teeth, where precise color matching is desired the most. Also, it is extremely easy to get perfect measurements of premolars (respecting the positioning and measurement principles described in the user manual), and depending on the patient and clinician skills, it is possible to get good measurement of molars.
This feature will come later in 2022. Stay tuned!
Optishade Styleitaliano gets precise and accurate L*a*b* coordinates for each color and its appearance in the mouth. With this precise data, there are endless applications.
The most important is the compatibility with the Matisse software for perfect ceramic restorations. With this software, you can calculate the substructure, ceramic mixing, framework staining and many other color features for ceramic restorations in challenging color matching cases, taking into account the substrate and available space among other things.
Optishade is useful for color research, shade estimation, treatment quality check, bleaching tracking, side-to-side comparison, aging of dental materials, denture teeth selection and to track any color change that might occur in natural teeth or dental materials. Future applications are already being developed.
Regarding accuracy, Optishade Styleitaliano (OS) readings are aligned with spectrophotometer data, meaning that when reading shiny surfaces within the dental color space the measurements have an average error under 0,5 DE. Those numbers, obtained with the highest standards allow OS numbers to be extrapolated to applications in colorimetry for research and material development.
Repeatability tests were done with more than 10,000 measurements that fell into the declared precision values (0,2 to 0,4 DE94 in the same device and 0,3 to 0,5 DE94 with different devices).
If you need to perform an accuracy or repeatability test for research purposes, contact jordi@styleitaliano.org
For measuring, Optishade Styleitaliano has its own calibration method. Images obtained with Optishade Styleitaliano are already normalized and provide all the needed color information. No post-production, software analysis or further treatment is needed. Grey cards or color checkers are not useful for this system.
For layering and mixing predictions, Matisse Software, is compatible with several Grey Cards which allow to create ceramic restorations with a DSLR camera. Nevertheless Optishade Styleitaliano is the suggested Matisse image acquisition method, as grey cards and color checkers were found to be less precise.
If you need to measure color checkers for research purposes, please contact jordi@styleitaliano.org
No absolutely not. When measuring a natural tooth, the aim is not to have a result showing green. The measure is the measure and it will simply show you how «far» you are from the closest color in the database. Natural teeth have hundreds of colors different from the shade guides.
If your result shows green, then you are close from an existing color in the shade guide. If you result shows you orange or red, it just means that the color you have just measured is less close.
Thanks to the two L*a*b* coordinates given (the ones of the Database and the ones of the tooth measured), an experimented technician will be able to interpret that he needs for example more L* (light), more a* (red) and maybe less b* (yellow).
