The cusp was lost when the technician bumped the tooth during induction. Crown amputation and intentional root retention can only be done in cases like this were the tooth root bears no surrounding periodontal ligament, there is no endodontic disease and the root is being replaced by bone grossly and radiographically.

This is the same patient from the prior post.  This is an example of Type I tooth resorption on the mesial root and Type II resorption on the distal root.

Tooth Resorption Cat 1 Additional Images of the Previous Patient with Canine Tooth Resorption

Radiographically you can see the periodontal ligament space on the mesial root classifying this as type I tooth resorption. This requires full root extraction. In the distal root the space is not present and bone is replacing the rooth. In this case crown reduction of more specifically here partial tooth extraction may be performed to remove tooth to the point where only bone is present. This requires extensive experience and a very high powered head surgical magnifyer to perform properly.
