Blal K, et al. - The purpose of this study was to investigate the relation between irretrievable abutment healing caps (AHCs), temperature, and the torque required to remove the AHCs from implants. It was possible to conclude that cooling the AHC reduced the torque required for its release from the implant within the limitations of this study. Moreover, this finding could be relevant to the removal of prosthetic abutments with irretrievable screws.
