according to : Dr. Leon Chen DMD, MS. Dental Implant Institute Las Vegas
Many doctors are reluctant to use trephines to remove osseointegrated implants because the wide blades cause them to often remove more bone than is needed, and they also create large amounts of heat which can often destroy too much bone and tissue.


Dr. Chen Invented these modified trephines for the sole purpose of removing implants. Dr. Chen's Explant kit features trephines which are minimally damaging, they have thinner blades and many different sizes, which fit many different sizes of implant, which allow for less trauma. Ventilation holes help reduce the heat caused by friction.


This makes Dr. Chen's Explant Kit a clearly better choice for implant removal than a regular trephine.
