A comparative finite element analysis of titanium, poly-ether-etherketone, and zirconia abutment on stress distribution around maxillary anterior implants.

Background: The aim of this study was to investigate the influence of abutment material, alveolar bone density, and occlusal forces on stress distribution around maxillary anterior implants.

Materials And Methods: An study was conducted. The maxillary anterior implant was modeled using a three-dimensional finite element model in D2 and D3 bones with three different abutment materials: titanium, zirconia, and poly-ether-ether ketone (PEEK).

Influence of dental magnets on human brain activity: A quantitative EEG analysis.

Purpose: The magnetic field is known to attenuate mental depression, but it is not clear on the effect of dental magnets on human brain activity. Therefore, this study was to determine the influence of magnetic field from intraoral magnets on the human brain activity by analyzing the changes in alpha waves.

Materials And Methods: Twenty complete denture male patients aged between 50 and 60 years were included after their consent.
