Summary

A post-market, multi-centre, prospective, open, randomized-controlled, non-inferiority clinical study to compare short-term performance and safety of the Straumann PURE 2-piece Ceramic Implant with Straumann Bone Level Implant using a fully digital workflow.

Conditions

  • Dental Implants, Single-Tooth

Interventions

DEVICE

Ceramic Dental Implant

The ceramic implant will be placed in healed extraction sockets in the premolar-to-premolar area in the mandible and maxilla for single tooth replacement followed by prosthetic loading after 4 months healing time. Type 4 surgery will be performed as defined by the ITI Consensus Statements for Implant Placement in Extraction Sockets: healed sites, typically around 16 weeks after tooth was extracted or after tooth was lost to allow complete healing of the ridge as well as soft- and hard tissue maturation. Both SG and CG receive routine treatment, only the choice of the implant material is defined by the study protocol.
