SCANTIST 3D–discover the first 3D scan
spray that evaporates automatically
after 20 minutes
An interview with Dr Sebastian Gell, co-owner of Scanningspray, the company that developed SCANTIST 3D
By Claudia Duschek, Dental
Tribune International
When using even the most
modern extra-oral scanners, it is
usually necessary to use matting
sprays to achieve great accuracy in
digital models. With the aim of improving scan quality, a German
company has developed SCANTIST
3D, a new 3D scan spray that was
specifically developed for extra-oral CAD/CAM applications in
dentistry. In this interview,
Dr Sebastian Gell explains the
main features and advantages of
the spray, which allows, for example, accurate scans of transparent
objects.
Dr Gell, could you please tell us
more about the need for digitisation in dental laboratories?
Nowadays, the number of dental restorations such as prostheses
produced by conventional means is
continuously decreasing. The desire for restorations made of
high-performance ceramics, which
increases aesthetic demands and
high-precision requirements, has
led to the development of digital
manufacturing processes using
computer-aided design (CAD) and
computer-aided
manufacturing
(CAM). Digitisation has therefore
become an essential process in the
fabrication of dental restorations in
modern dental laboratories.
The surface of the scan object is
digitised with the help of a 3D scanner, and a 3D model is created from
the data obtained. The digital
model can then be compared with
actual parameters and, in the event
of deviations, changes can be made
to the physical model. In the additive manufacturing process, digital
models also serve as input data for
a 3D print.
In order to ensure exact 3D
scan results, it is often necessary
to apply a coating to the scan object. How can optimal scanning
conditions be achieved with
SCANTIST 3D?
Three-dimensional scanning
requires that light emitted by the
scanner is reflected from the scan
object back into the sensor of the
scanner. In the case of a transparent or translucent surface, for example, the light passes through the
surface instead of being reflected
from it. As a result, the scanner is
not able to capture the surface
structure.
For this reason, it is often necessary to apply a coating before scanning objects that are transparent,
translucent, reflective, shiny or
highly structured with deep pockets. SCANTIST 3D forms a thin layer
of white, homogeneous coating
which eliminates reflections and
other inhomogeneities and thus
provides ideal conditions for optical scanning.
The handling is extremely simple and comfortable. SCANTIST 3D
is applied evenly to the surface of
the scan object at a distance of 5 to
10 cm. The spray cans are equipped
with a special valve with a very fine
nozzle. This makes handling easy
and efficient, as the spray is applied
with pinpoint accuracy and precision. The coating has a layer thickness of about 2 µm and adheres to
all materials, even to very smooth
surfaces.
SCANTIST 3D is the first evaporating extra-oral 3D scan spray. Why
is this a crucial advantage for dental
laboratories?
Conventional extra-oral 3D
scan sprays are based on ground
white colour pigments. The disadvantage is that the applied coating
must be removed again after scanning. The cleaning process is very
tedious, costly and time-consuming. Unlike conventional sprays,
the coating of SCANTIST 3D VANISHING evaporates about 20 minutes after application. The spray
does not contain pigments and
thus avoids the pigment-contamination of sensitive areas, such as
laboratories, equipment and users.
You can even apply SCANTIST 3D
VANISHING directly, on the spot,
without taking any costly precautions to avoid pigment-contamination. Overall, SCANTIST 3D eliminates the fundamental application
problems of conventional 3D scan
sprays and thus greatly increases
efficiency and productivity within
the digitising process.
Dr Sebastian Gell is a professor of business administration at FH Aachen University of Applied Sciences in Aachen in Germany. He is also a co-founder of Scanningspray, the company specialising in surface matting for optical 3D scanning
that developed SCANTIST 3D. (Images: Sebastian Gell, SCANTIST 3D)
This new scanning spray is free
from titanium dioxide. Why is this
important?
In a scientific opinion issued on
14 September 2017, the Committee
for Risk Assessment of the European Chemicals Agency proposed
the classification of titanium dioxide as a Category 2 carcinogen by
inhalation. Based on this opinion,
titanium dioxide has now officially
received its carcinogenicity classification according to the EU Classification, Labelling and Packaging
Regulation. The classification as a
carcinogen by inhalation applies to
mixtures in powder form containing 1% or more of titanium dioxide
which is in the form of, or incorporated in, particles with an aerodynamic diameter ≤ 10 µm. This criterion is met by many of the sprays
used for scanning containing titanium dioxide. Based on this drastic
change, I expect that many dental
laboratories will be looking for less
harmful spray alternatives.
Is the product globally available, and how can technicians
order it?
We are currently building our
global reseller network and are
therefore very happy about dealer
inquiries. Dental technicians can
contact their usual sources and
dental retailers and make them
aware of SCANTIST 3D
Dental 3D scan sprays form a matt, white and homogeneous coating when applied. This reduces reflections and other inhomogeneities and thus creates excellent scanning conditions. (Image: SCANTIST 3D)
