Zimmer® IMPLANTS
Zimmer® implants are available with two surface texture options, a
hydroxylapatite (HA) particle blasted and acid washed surface (MTX)
or a dual HA coated (MP-1®), MTX surface. The acid wash of the
MTX surface roughening process is designed to remove embedded HA
particle and does not etch the titanium surface. Zimmer's MP-1® Ha
coating procedure increases the HA crystal density to around 90 percent on
the surface of the implant.
Tapered Screw-Vent® (TSV)

Tapered Screw-Vent®
titanium grade 5 implants are machined with a
slightly tapered body geometry and triple lead thread design. The triple
lead threads will force the implant at a faster rate in to the osteotomy
site as compared to a single lead thread design implant. Four implant
diameters (Fig.1) of 3.7, 4.1, 4.7 and 6mm in five lengths of 8, 10, 11.5, 13 and
16mm are available from Zimmer® for this implant system. 3.7 and
4.1mm diameter implants share the same implant/abutment interface
(platform) of 3.5mm. 4.7mm diameter implants are machined with a 4.5mm
implant/abutment interface and 6.0mm diameter implants are produced with a
5.7mm platform. The implant/abutment interface consist of a internal
hexagon which is dimensioned according to the platform diameter.
Fig. 2
Each of the implants is packaged with a cover screw and color coded
fixture mount. The color coding scheme is carried throughout the complete
implant system for easy platform identification. Green signals the 3.5mm
platform, purple signifies a 4.5mm platform and yellow corresponds
to the 5.7mm platform. The fixture mount may serve as a delivery device,
impression coping and temporary abutment. A oblong lacuna at the apex of the
implant creates cutting surfaces and serves as a reservoir for bone chips.
Two options are available in regards to the extent of the surface treatment
at the coronal aspect (Fig.2) of the implat. Option one is a 1mm machined collar
separating the textured area from the implant/abutment interface and option
two extendes the textured area to the edge of the implant/abutment
interface with added micro groves at the coronal aspect.
Screw-Vent® (SV)

Screw-Vent® titanium
grade 5 implants have a parallel wall body
geometry and a triple lead thread design. The triple lead threads will
force the implant at a faster rate in to the osteotomy site as compared to
a single lead thread design implant. Three implant diameters (Fig.3) of 3.3, 3.7
and 4.7mm in four lengths of 8, 10, 13 and 16mm are available from
Zimmer® for this implant system. 3.3 and 3.7mm diameter implants share
the same implant/abutment interface (platform) of 3.5mm while 4.7mm diameter
implants are machined with a 4.5mm implant/abutment interface. The implant/abutment
interface consist of a internal hexagon which is dimensioned according to
the platform diameter.

oblong lacuna at the apex of the implant creates cutting surfaces and
serves as a reservoir for bone chips. The surface treated area of the
implant is separated from the implant/abutment interface by a 2mm machined
collar.
Trabecular Metal
Fig. 4
Trabecular Metal implants are machined out of
grade 5 titanium with a
jacket of Tantalum in the mid body section of the implant. This jacket has a
trabecular bone like structure made of Tantalum (Ta). Producing the trabecular
bone like structure involves
pyrolizing
polyurethane foam and turning it in to
reticulated vitreous carbon. The porous carbon structure is then subjected
to a Tantalum vapor deposition process encasing each individual filament of
the carbon with a few micron thick layer of pure Tantalum (Fig.4). A recess machined
in to the mid section of the implant body is then fitted with the porous Tantalum
jacket. The intent of the trabecular structure jacket is to not only achivve bonne
growth on to the implant surface but also in to the implant.
Fig. 5
Trabecular Metal implants are compatible with Tapered Screw-Vent®
(TSV) implants surgical instrumentation and prosthetic components. Two surface
texture extent options are available. One option carries the MTX surface
to the edge of the implant/abutment interface while the second option leaves a
0.5mm machined collar at the implant/abutment interface. Implants are produced
in three body diameters of 4.1, 4.7 and 6.0mm with respective prosthetic platform
diameters of 3.5, 4.5 and 5.7mm. Each implant body diameter is offerd in three
lengths of 10, 11.5 and 13mm. Shallow micro threads at the coronal portion of
the implant body and deeper threads in the apical area (Fig.5) result in slightly less
bone engaging inital stability due to the non threaded shape of the Trabecular
Metal in the mid section of the implant body. A cover screw and a pre
mounted fixture mount are packaged with each of the implants.
Zimmer® One-Piece
Fig. 6
Zimmer® One-Piece
grade 5 titanium implants are machined with a abutment for cementable
restorations as a mono block, forming a singular entity (Fig.6). The tapered body
geometry has a double (3.7, 4.7mm diameter) or triple (3.0mm diameter) lead
thread design. Increasing the number of lead threads will force the implant
at a faster rate in to the osteotomy site as compared to a single lead
thread design implant. Three implant diameters of 3.0, 3.7 and 4.7mm in
four lengths of 10, 11.5, 13 and 16mm are available from Zimmer® for
this implant system. 3.0mm diameter implants are not offered as a 16mm length
version. The abutment portion of the implant is machined as a straight and
a 17° angled option. A 1.7mm machined collar separates the MTX surface
treated area from the intended margin of the final restoration. One-Piece
implants are not available with a HA coated (MP-1®) surface. These
types of implants require the restorative dentist to take a
abutment level
impression.
AdVent®

AdVent®
titanium grade 5 implants
(Fig.7) have a slightly tapered body geometry
and a triple lead thread design. The triple lead threads will
force the implant at a faster rate in to the osteotomy site as compared to
a single lead thread design implant. Two implant diameters of 3.7 and
4.7mm in four lengths of 8, 10, 13 and 16mm are produced by
Zimmer® for this implant system. 4.7mm diameter implants are machined
with two different platform diameters of 4.5mm and 5.7mm. The implant/abutment
interface consist of a internal hexagon which is dimensioned according to
the platform diameter. Each of the implants is packaged with a cover screw
and cover screw extender. The extender may be utilized to transform the cover
screw in to healing abutment. A oblong lacuna at the apex of the
implant creates cutting surfaces and serves as a reservoir for bone chips.
The surface treated area of the implant is separated from the
implant/abutment interface by a 3mm machined collar.
SwissPlus®
Fig. 8
SwissPlus®
titanium grade 4 implants are machined with a parallel (Fig.8) and tapered
(Fig.7) body
geometry and a outside double lead thread design. The double lead threads
will force the implant at a faster rate in to the osteotomy site as
compared to a single lead thread design implant. Parallel geometry
SwissPlus® implants are produced in two implant diameters of 4.1
and 4.8mm in four lengths of 8, 10, 12 and 14mm. Both implant diameters
share the same internal octagon abutment/implant platform diameter of 4.8mm.
The MTX surface treated area of SwissPlus® parallel geometry
implants is separated from the implant/abutment interface by a 2.5mm
machined collar.
Fig. 9
Tapered geometry SwissPlus® implants (Fig.9) are produced in two implant
diameters of 3.7 and 4.8mm in four lengths of 8, 10, 12 and 14mm. Both
implant diameters share the same internal octagon platform diameter of
4.8mm. A 3.8mm platform, internal hexagon abutment/implant interface
completes the tapered SwissPlus® product group offering. The MTX
surface treated area of SwissPlus® parallel geometry implants is
separated from the implant/abutment interface by a 2mm machined collar.
Each of the implants is packaged with a fixture mount/abutment and a 2mm
height cover screw/healing abutment. A oblong lacuna at the apex of the
implant creates cutting surfaces and serves as a reservoir for bone chips.
