Extractions can be stressful for the patient and practitioner. This becomes especially true when the tooth being extracted has significant coronal breakdown, making it more difficult to grasp with traditional forceps. Traditional forceps also require significant hand force to extract the tooth and there is potential for fracture of the surrounding socket walls.

The Physics Forceps consist of a set of 4 forceps or 2 forceps. Both sets of instruments comprise forceps with a beak on one of the terminal ends of the instrument and a wide round tip on the other terminal end. A soft bumper guard is placed on the bumper to cushion the soft tissue it will contact.

The instruments were designed to use fulcrum mechanics to decrease the force needed to extract a tooth. This takes advantage of the fact that the palatal/lingual bone is denser than the buccal/facial and its crest is more coronal. The forceps beak is positioned on the lingual as apically as possible, with the bumper guard positioned on the buccal soft tissue on the lateral aspect of the ridge to create a first-class lever.

A rotational motion is used to expand the socket around the tooth atraumatically, which then continues to displace the tooth in a buccal direction while preserving the buccal bone. The rotational motion with the fulcrum magnifies force placed in the tooth, decreasing the force needed by the practitioner. The process is gentler on the delicate buccal crestal bone with less potential for osseous fracture that can complicate subsequent treatment in that area.
