00:00:00.500 --> 00:00:04.000
Welcome to the Schwenningen Campus of Furtwangen
University.

3
00:00:04.500 --> 00:00:07.500
The TriMaBone Interreg project aims to create

4
00:00:08.000 --> 00:00:10.000
new 3D-printable bone substitute materials

5
00:00:10.500 --> 00:00:13.000
which allow customised applications for the
patient.

6
00:00:13.500 --> 00:00:16.000
To do so, a bone replacement material

7
00:00:16.500 --> 00:00:19.500
based on chitosan is being developed by a work
group consisting of

8
00:00:20.000 --> 00:00:22.500
the University of Haute-Alsace, the University
of Koblenz,

9
00:00:23.000 --> 00:00:25.500
the University of Applied Sciences Northwestern
Switzerland

10
00:00:26.000 --> 00:00:28.000
and Furtwangen University.

11
00:00:29.000 --> 00:00:36.000
A frequent problem with bone defects is, especially
in the dental field,

12
00:00:37.000 --> 00:00:41.000
that the body cannot fill defects or gaps beyond
a certain size by itself.

13
00:00:42.000 --> 00:00:45.000
In these cases the defect must be filled with
a bone substitute material

14
00:00:46.000 --> 00:00:48.000
which stimulates the body to form new bone.

15
00:00:49.000 --> 00:00:51.000
Ideally, this material degrades over time

16
00:00:52.000 --> 00:00:54.000
and is replaced by the body's own bone.

17
00:00:55.000 --> 00:00:58.000
These are called bioresorbable materials.

18
00:00:59.000 --> 00:01:02.000
However, the shape depends on the cause of
the defect,

19
00:01:03.000 --> 00:01:07.000
for example, due to an accident or a surgical
intervention.

20
00:01:08.000 --> 00:01:10.000
Commonly used prefabricated implants are quite
uniform and

21
00:01:11.000 --> 00:01:16.000
must first be adapted to the defect in question,

22
00:01:17.000 --> 00:01:21.000
which is inconvenient for the patient.

23
00:01:21.000 --> 00:01:23.000
This is where 3D printing comes in,

24
00:01:24.000 --> 00:01:28.000
as it allows the implant to be customised precisely

25
00:01:29.000 --> 00:01:32.000
making it easier for the patient.

26
00:01:32.000 --> 00:01:35.000
The focus of our project is on modifying chitosan

27
00:01:36.000 --> 00:01:38.000
to make it suitable for 3D printing,

28
00:01:39.000 --> 00:01:42.000
since it is not yet possible to 3D-print chitosan.

29
00:01:42.000 --> 00:01:43.000
Why chitosan?

30
00:01:44.000 --> 00:01:46.000
On the one hand, because of its properties:

31
00:01:47.000 --> 00:01:48.000
it is antibacterial,

32
00:01:48.000 --> 00:01:52.000
biocompatible (well accepted by the body) and,

33
00:01:52.000 --> 00:01:56.000
as mentioned at the beginning, is bioresorbable.

34
00:01:57.000 --> 00:02:01.000
On the other hand, because it can also be produced
in the quantities needed

35
00:02:02.000 --> 00:02:05.000
to meet the annual demand for bone substitute
materials.
