BioHorizons® IMPRESSION COPINGS
1. External Hex
Fig. 1
Although the 3 inOne abutment (Fig.1) supplied with each implant can be
used as a indirect
(closed tray) impression coping, a ball top screw (Fig.1, right) should be
used instead of the included abutment screw at the time of impression
taking. The ball top screw is available for 3.7mm platform diameter
(catalog # 213-235) and 4.2mm, 5.2mm, 6.2mm platform diameters (catalog #
214-235). A dedicated indexed impression coping (Fig.2) for the
direct (open tray) fixture
level impression technique is also offered for all platform diameters.
Fig. 2
BioHorizons® carries non hexed direct impression copings in their portfolio, these impression coping should only be
used after careful deliberation because if the proposed prosthetic design needs
to be changed after impression taking a time consuming second impression with
hexed impression copings may need to be taken. The 3 inOne impression coping
and all other impression copings are color coded according to platform diameter
(yellow 3.7mm, green 4.2mm, blue 5.2mm and purple 6.2mm).
Fig. 3
Abutment for Screw abutments may be impressed direct or indirectly. The
direct impression coping (Fig.3 right) is machined as a two component set,
impression coping body and fixation screw while the indirect impression
coping (Fig.3, left) is rendered as a unibody component incorporating the
impression coping body and scew in to a single entity. Either impression
coping may be utilized for any installed Abutment for Screw regardless of
the implant platform diameter or connection type (external hex, internal,
Single-stage) implant.
2. Internal, Tapered Internal Implant
Fig. 4
Although the 3 inOne abutment (Fig.4) supplied with most implants can be
used as a indirect
(closed tray) impression coping, a ball top screw (Fig.4, right) should be
used instead of the included abutment screw at the time of impression
taking. A universal ball top screw (Fig.4, right, catalog # PXBT) is
available for all platform diameters.
Fig. 5
Dedicated impression copings with different emergence profiles for
the indirect (Fig.4, closed tray) and direct (Fig.6, open tray)
fixture level impression technique are also offered for all platform diameters.
BioHorizons® carries non hexed impression copings in their portfolio,
these impression coping should only be used after careful deliberation because if the proposed
prosthetic design needs to be changed after impression taking a time consuming
second impression with hexed impression copings may need to be taken.
Fig. 6
The 3 inOne impression coping and all other impression copings are color coded according
to platform diameter (yellow 3.5mm, green 4.5mm and blue 5.7mm).
Dedicated impression copings are offered in three emergence profile diameters
for each platform diameter, congruent with available transmucosal healing
abutment emergence profiles.
Abutment for Screw impression copings see external hex Abutment for
Screw section above.
3. Single-stage Implants
Fig. 7
Fixture level impression copings (Fig.7) for Single-stage implants are
only available for the
direct
(open tray) impression technique and no choice in emergence
profile diameters. This shortcoming could be overcome by using indirect
(closed tray) or direct (open tray) fixture level impression copings from BioHorizons® Internal
and Tapered internal implant systems in compliance with appropriate platform
diameters. If this work around is employed the laboratory needs to be alerted
on the Rx that the implants are actually Single-stage and not Internal or
Tapered internal system implants. Single-stage implants were primarily
designed for Simple solution, abutment level impression techniques. Please
see section four below for Simple-solution abutment level impression copings and
technique.
Abutment for Screw impression copings see external hex Abutment for
Screw section above.
4. Simple Solution Abutment
Fig. 8
Simple-solution abutment level
impression copings are made of plastic and
are color coded (yellow 4.5mm, green 4.5mm and blue 5.7mm) in accordance
to the implant platform diameter. Six different configurations are available,
two for each platform diameter. Simple-solution abutments are machined in
two heights of 4mm and 5.5mm. Impression copings are chosen in regards
to the abutment height (Fig.8) within the platform diameter group.
Fig. 9
Each Simple-solution abutment is machined with two opposing flat sides in the long
axis of the abutment and corresponding flat sides in the impression coping.
The impression coping is snapped over the installed abutment, lining up
the flat sides of the abutment with the impression copings flat sides.
Impression copings have indicator notches (Fig.9) on the outside of the coping
along the long axis corresponding to the flat side inside the impression
copings to ease proper orientation of the coping over the abutment.
5. Laser-Lok 3.0 Implant
Fig. 10
The only impression copings available for the Laser-Lok 3.0 implant system
are indexed and non indexed direct
(Fig.10, open tray) copings. Caution should be
used when utilizing non hexed impression copings because these should only
be utilized when a splinted substructure with a minimum of two implants as
part of the final restoration is the treatment goal. It is best to always
use hexed impression copings in case the restoration design needs to be
modified from the original planned design due to unfavorable or unforeseen
conditions.
