Tapered Screw-Vent Features & Benefits

Tapered Screw-Vent^® prosthetics offer a platform designed for success.

Zimmer’s proprietary friction-fit internal hex connection is a unique combination of designs that has been shown to reduce stress on crestal bone and to resist abutment screw loosening, thus creating favorable conditions for bone level maintenance.^1-3

Advantages of the friction-fit internal hex connection

A lead-in bevel and 1.5mm deep internal hex reduce horizontal bone stresses and distribute forces deep within the implant, thereby shielding the retention screw from excessive loading.^1-3
The proprietary friction-fit component of the connection virtually eliminates abutment micromovement (a primary cause of screw loosening) when tightened to the recommended 30 Ncm of applied torque.¹ This means fewer return patient visits, less chair time, and increased patient satisfaction.
