An Indirect Method to Measure Abutment Screw Preload: A Pilot Study Based on Micro-CT Scanning.

This study aimed to measure the preload in different implant platform geometries based on micro-CT images. External hexagon (EH) implants and Morse Tapered (MT) implants (n=5) were used for the preload measurement. The abutment screws were scanned in micro-CT to obtain their virtual models, which were used to record their initial length.
