Influence of Screw Access Channel on All Ceramic Cement-Retained Implant Supported Posterior Crowns

  title={Influence of Screw Access Channel on All Ceramic Cement-Retained Implant Supported Posterior Crowns},
  author={A. Khalifa and Dawlat Mostafa and Mohamed Moataz Khamis},
Statement of the problem: The presence of a screw access channel on the occlusal surface of implant-supported all ceramic crowns may reduce the fracture resistance of the restoration. Purpose: Evaluate the effect of screw access channel on the fracture resistance, fracture pattern and defects at the fracture origin after subjecting to vertical compression load on cement retained implant posterior crowns. Material and methods: Four parallel groups, eight specimens each, were examined in this… Expand
