Prior to attachment, the posts adapted for the purpose were sand-blasted at 110µm/2 bar
and then degreased. After polishing and steam-cleaning, the internal walls of the crowns of
the resin bridges only required thorough cleaning with acetone.
The bridges 1-5 were connected using „„AMBARINO Hard Flow“/clear # 2008005192
Bridges 1-5
The bridges 6-10 were attached using „PANAVIA F 2.0/TC“ A+B paste (# 00312A – 00171B)
Bridges 6-10
The following defect on bridge 5 and the cracks in the bridge unit (bridge 10) were
documented here photographically prior to the start of the test:

Embedding of the 3-unit bridges in resin in the sample containers. However, in the case of
PEM-I, a hole (Ø 12 mm + Ø 10 mm) was first milled in the resin Blancs.
The samples are installed in the mastication simulator and appropriately oriented towards the
antagonist spheres.

Figure legends for the REM images:
1) Bridge no.: 4
Bridge 7 Bridge 8
Bridge 9 Bridge 10
The cover sheet shows an overview of bridge no. 4 (Fig. 1) and an REM image of the bridge
(Fig. 2) for improved orientation.
We have documented a total of four contact points in this case (Figs. 3 – 6). This bridge was
also the only one in which hairline cracks were found along the length of its larger
components (Figs. 7 – 9). These were located in the left fissure next to the marginal ridge of
tooth number 6 and close to the dominant contact point on number 5. In contrast, no such
further hairline cracks were detected on tooth 4 and on the distal region of the molar. It is not,
however, possible to judge in retrospect whether these hairline cracks occurred due to the
stresses in the mastication simulator or whether they had occurred beforehand during
mechanical processing. It is also of note that this tooth had the smoothest surface.
2) Bridge no.: 6
The overview is designed in the same way (Figs. 1 + 2). The three contact points that were
present were documented in the REM images Figs. 3 – 6 and there were no abnormalities
apart from an overall rougher surface.

3) Bridge no.: 10
Once more, the overview (Figs. 1 + 2). The four contact points that were present were
documented in the REM images Figs. 4 – 7. The abnormal abrasion (Fig. 3) on the palatine
cusp of the bridge unit is not due to the antagonist sphere in the mastication simulator. The
palatine cracks in this bridge that had been noted at the start have not widened and are once
more documented in a REM image in Fig. 8. This bridge also exhibits a rough surface.

Summary:
The load on the ten bridges made from the nanocomposite produced by the company
"creamed" caused no incidents.
Following the removal of all sample bridges, no cracks or other serious damage were
determined either with the naked eye or under magnification. Even the extended microscopic
assessment after 24 hours revealed no changes to the previous, positive result.
A requested examination and analysis of the contact points created by the antagonist sphere
revealed no significant wear or any cracks due to such wear on the three samples selected
especially for this purpose (exception: microscopic cracks on bridge 4). Please refer to the
separate REM documentation with the associated figure legend provided above.
Likewise, the defects documented on bridges no. 5 and no. 10 at the start during
thermocycling had not deteriorated or expanded.
Both composites used in this test were equal in quality to the naked eye.

The huge challenge to a new material in prothetic dentistry
AMBARINO high-class
The load test in the mastication simulator:
1.2m load cycles at 70N / thermocycles corresponds to the natural oral load due to mastication
exerted over more than five years.
Documentation on 10 three-unit bridges (14 crown – 15 bridge unit – 16 crown), fully anatomically
milled from an AMBARINO high-class round blank of 18mm in thickness and of the colour A2,
produced by the company "creamed", in the mastication simulator.
The thinnest portions, at 0.2 – 0.3 mm, were located in the centre of the fissure and also occasionally
in the cervical margins of the crowns.
The milled bridges were extracted from the round blank, briefly processed, polished and numbered
from 1-10.
During extraction of bridge no. 5, a defect occurred cervically in the mesio-buccal area on crown 14
(photo, page 2, bottom left).
Cracks can be seen on bridge no. 10, bridge unit 15, which were probably caused by the lack of
cooling during extraction using the diamond Blanc.
The defective bridges no. 5 and no. 10 were consciously included in the test.
The ten individual bridges were each attached to a custom-made post in a mastication simulator.
The bridges nos. 1-5 were connected using the dual-hardening composite flow resin, AMBARINO
Hard Flow, bridges nos. 6 – 10, by contrast, using Panavia F.
Thermocycling was conducted simultaneously, in addition to the load cycles using an antagonist
sphere.
The summary on AMBARINO high-class, produced by the company "creamed", is extremely positive
based on the completed test (1.2m load cycles at 70N / thermocycles).
Of particular note is that the defective crown 14 in bridge no. 5 and the bridge unit 15 in bridge no. 10
exhibited no further changes even after the load test – not even the thermal stresses were sufficient to
change the defects that were present.
A comparison of the attachment materials AMBARINO Hard Flow and Panavia F revealed absolute
equality, whereby it must be noted that AMBARINO Hard Flow, with its broad spectrum of applications
and its excellent physical properties, provided crown 14 in bridge no. 5 with additional strength. This
bridge also survived the load cycles with no problems at all.
Due to the high strength of AMBARINO high-class, produced by the company "creamed", the material
can only be polished after appropriate pre-processing and the use of a special diamond paste. In turn,
this means an exceptionally good polish is achieved, therefore providing a surface highly resistant to
plaque (see the company "creamed" instructions for use).

AMBARINO high-class nanotechnology for CAD/CAM systems
The indication spectrum ranges from crowns, bridges, veneers, inlays, onlays, telescopic
prostheses, tertiary structures, fully anatomically milled, partially anatomically milled
(optimize with nanocomposite veneers, paint) to milled emergence profiles, implant
superstructures and abutments.
The alternative to full ceramics and veneer ceramics
General:
- Dyed using Vita colours, which results in an exceptionally natural colour integration
(chamaeleon effect).
- The nanoparticles, composition of the filler and distribution of particle size conform to
particular specifications, such that milling is possible in marginal areas (0.2mm) without
avulsion occurring or any reduction in stability.
- It can be exceptionally well polished, allowing additional sealing of the nanostructure and
thus outstanding, long-lasting shine.
- With appropriate oral hygiene, the deposition of plaque or Blancoloration is hardly to be
expected for tooth replacements.
- The use of tooth replacements made from nano composites has been employed for
years
- in
dental practice (AMBARINO Nanocomposite, produced by the company "creamed" –
paste-like mass) for the restoration of teeth and the indirect production of inlays and
veneers.
