Curve represented for each specimen under compression: (a) artifact when the compressive force is absorbed for the final seating of the stem into the palatal indentation, (b) increased compressive force to the point of breakage of the root or initial failure, (p) initial failure or fracture root, (c) decompression after initial failure, (d) detachment pieces, (e) slight increasing compression due to friction of post on root walls, and (f) horizontal line represents a full decompression when post is completely removed.
