Tapered Screw-Vent® Implants

TSV™ Implant Overview

Approaching 20 years of clinical use and over 5-million implants sold, the Tapered Screw-Vent (TSV) Implant has gained the trust of thousands of surgeons worldwide to deliver successful patient outcomes. This success is well documented with 130 peer-reviewed papers1 and a 98.7% cumulative survival rate.1-14
 

Primary Stability

Primary stability achieved by using Tapered Screw-Vent Implants enables immediate placement and/or immediate loading in appropriately selected patients.2, 7, 15

• The triple-lead threads are designed to achieve intimate bone contact at implant placement.15
• The soft-bone surgical protocol enables bone compression and provides additional stability in poor quality sites.15
• In dense bone, the stepped finishing drill enables apical bone engagement for initial stability.15

 

Secondary Stability

Documented MTX Surface Advantages

• Tapered Screw-Vent Implants are made of grade 5 titanium alloy chosen for its biocompatibility32 and strength.33-35
• Minimum tensile and yield strength requirements for this material, set by the American Society for Testing and Materials (ASTM) and the International Organization for Standardization (ISO), are 32% and 59% higher respectively than those of the strongest CP titanium available.33-35
• Zimmer Biomet Dental specifications require that the grade 5 titanium alloy used in Tapered Screw-Vent Implants meet or exceed the combined standards of ASTM and ISO.1

 

Documented MTX Surface Advantages

• High degree of bone-to-implant contact (BIC) and osteoconductive capacity.16, 17
• Successful clinical results under conditions of immediate loading.2, 5, 7, 9-11
• Greater than 90% BIC as compared to 42-77% BIC achieved by TPS coated, sandblasted and acid-etched, oxidized and HA-coated surfaces placed in grafted human sinuses.17
