Zimmer® Implants

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)

Fig. 1

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)

Fig. 3

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.

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®

Fig. 7

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.
