Improved scanning of shiny telescope prosthesis

07 November, 2022 / editorial

In digital dentistry, transparent and shiny surfaces have to be matted for scanning purposes. Now there is a new scanning spray, SCANTIST 3D, which gives surfaces a fine, homogeneous matt coating. The spray coating does not have to be removed after scanning because the spray completely evaporates. In addition, SCANTIST 3D is free of pigments such as harmful titanium dioxide.

SCANTIST 3D – the self-disappearing extraoral 3D scan spray for dental applications. 

Hazardous substances in many conventional dental sprays
At Walter Stein Dental Laboratory (Germany), the staff have many years of experience with scanning sprays. “Using scanning sprays always made us feel a bit uneasy in the past. But we didn’t have a practical alternative until now,” according to Walter Stein. The owner of the dental laboratory is particularly concerned about the health aspects. Many conventional sprays contain pigments and titanium dioxide, which are said to have carcinogenic effects. It cannot be completely avoided that the staff may also be exposed to the spray mist when the objects are being treated.

Spray coating adheres stubbornly
Conventional sprays adhere stubbornly to surfaces and are very difficult to remove. This is time-consuming and detrimental to hygiene. The coating can never be completely removed; a residue will always remain on the objects and the surroundings. In addition, conventional sprays are often very coarse, which easily leads to an uneven spray coating. The actual surface data cannot be recorded correctly, which affects the accuracy of fit of the dental prostheses.

SCANTIST 3D dental spray – no pigments, homogeneous spray coating, complete sublimation
SCANTIST 3D scanning spray has been around since 2021. At Walter Stein Dental Laboratory, it has been in use for several months and the team is thrilled. SCANTIST 3D can be applied in a very thin and even layer, meaning that the scanners capture accurate surface data.

Moreover, SCANTIST 3D adheres to all the surfaces and is dry to the touch, making it particularly easy to use. What is special about the spray is that it evaporates by itself, thus completely eliminating the need for costly and time-consuming cleaning.

An entire work step is saved. Since the spray coating completely evaporates after approximately 20 minutes, the whole process is very hygienic.

Transparent and shiny surfaces, such as telescopic dentures, have to be matted for scanning purposes.
SCANTIST 3D is applied from a distance between 5 to 10 cm. It forms a homogeneous and very fine coating. The extension nozzle allows efficient and targeted application.
The new scanning spray SCANTIST 3D gives surfaces a fine, homogeneous matt coating. The coating thickness is between 2 to 4 µm.

Best scan results: The reliable data quality enables precise fabrication of the dental restorations.
Evaporation process: Since the spray coating completely evaporates after approximately 20 minutes, the whole process is very hygienic.

“But the most important thing for me,” emphasises Walter Stein, “is that SCANTIST 3D is free from harmful pigments and does not contain any titanium dioxide. The health aspects are becoming more and more important, especially among younger staff members. For me it goes without saying that creating good working conditions is a must. My employees have made clear their preference for SCANTIST 3D because of both its ease of handling and the health advantages. I’m totally with them on that.”

The young SCANTIST 3D team comprises engineers, inventors, and scientists who have set themselves the task of improving and simplifying scanning processes for dental restorations. With their extensive experience in the field of 3D scanning, the engineers are fully aware of the problem of permanently adhesive scan sprays and the laborious cleaning processes. Consequently, the team is working on ideal solutions to make life easier for users in the dental CAD/CAM field while, at the same time, considerably increasing the quality level of scan sprays.
