Zimmer Dental’s Internal Friction-Fit Connection: The Original Platform Force Shield

Many implantmanufacturers have tried to copy, but have never duplicated, Zimmer’s
internal friction-fit interface. With over 18 years of clinical success in the hands of thousands
of dentists worldwide, Zimmer’s Platform Plus™ Technology was the first to introduce an
indented platform interface that also shields both the abutment screw and crestal bone
region from concentrated occlusal forces. (...please click here to read more)

Tapered Screw-Vent, a connection you can depend on

Abutments for the Tapered Screw-Vent have a male hex that tapers one degree from the base of the abutment body to the Bottom of the hex. As the abutment is seated into the implant under applied torque, the abutment hex frictionally engages the walls of the implants internal hex. The result is a friction-fit that virtually eliminates rotation between components. Friction-fit technology far surpasses that of standard internal and external hex connections. Only when you combine friction-fit and internal hex, do you reach the most advanced evolution in implant connections.

Tapered Screw-Vent packaging includes a patented Fixture Mount/Transfer that functions as an impression post and a temporary abutment. Tapered Screw-Vent triple-lead threads increases primary stability, making it ideal for immediate implant techniques - another versatile implant system available from Implant support Services.

 

Technical Information - Implant properties and Dimensions

Implant Diameter:

Tapered Screw-Vent Implants are available in three body diameters: 3.7mmD, 4.7mmD and 6.0mmD

Implant material:

Tapered Screw-Vent and Screw-Vent implants are all manufactured from a medical grade titanium alloy with an Ultimate Tensile Strength of 130 ksi (896 MPa) and can withstand between 346-639 lbs (1539-2842N) of compression at 30°.

Implant platform:

The diameter is measured across the most coronal part of the implant. The Screw-Vent systems have three types of implant platform diameters and designs:

• 3.5mmD platform - (Fig. 1a & b). A 44° internal lead-in bevel extends from the outer most diameter (3.5mmD) of the implant platform into the internal hex of the implant. The internal hex configuration is 2.5mmD flat-to-flat with a depth of 1.5mm. Below the hexagon is a continuation of the inner chamber, which leads into the threaded area where the fixation screw is received.
  This platform is on all lengths of the TSV series of implants.
• 4.5mmD platform - (Fig. 2a & b). A 44° internal lead-in bevel extends from the outer most diameter (4.5mmD) of the implant platform into a flattened area or ledge. This ledge extends from the base of the lead in bevel to the internal hex of the implant. The internal hex configuration is 2.5mmD flat-to-flat with a depth of 1.5mm. Below the hexagon is a continuation of the inner chamber, which leads into the threaded area where the fixation screw is received.
  This platform is on all lengths of the TSVW series of implants.
• 5.7mmD platform - (Fig. 3a & b). A 44° internal lead-in bevel extends from the outer most diameter (5.7mmD) of the implant platform into a flattened area or ledge. This ledge extends from the base of the lead in bevel to the internal hex of the implant. The internal hex configuration is 3.0mmD flat-to-flat with a depth of 1.5mm. Below the hexagon is a continuation of the inner chamber, which leads into the threaded area where the fixation screw is received.
  This platform is on all lengths of the TSV6 series of implants.

Implant surface:

Medium-rough surface (MTX) created by blasting the surface with HA particulate. The MTX texturing process produces a surface which has uniform micropits in the critical 1-to-2 micron size range deemed optimum for bone apposition. The blasting and cleaning process preserves thread sharpness necessary for self-tapping.

The HA surface, referred to as MP-1 is applied to the mid section of all three implant designs in varying configurations. The pressurized hydrothermal post-plasma spray process (MP-1) was developed to convert the amorphous components of plasma sprayed HA coatings back into a high quality crystalline HA. The rate of calcium dissolution for the MP-1 coating was significantly lower than other commercially available HA coatings.
