Biochemistry Of Tooth Extractions
Thomas C. Abrahamsen, DDS, MS FACP
It is generally thought that the physical change of expanding the dental alveolar bone (socket) along with the severing of the periodontal ligament is the basis of a tooth extraction. Albeit that this does happen, an understanding of what is occurring biochemically is even more important. When the periodontal ligament is traumatized with forceps or elevators, hyaluronidase (hyluronate glycanohydrolase) is released. This is an enzyme that catalyzes the hydrolysis of the interstitial barrier, hyaluronan (hyaluronic acid), which is the cement substance (extracellular matrix) of all human tissue. Once this chemical breakdown of the periodontal ligament by hyaluronidase is sufficient, the tooth is released from its attachment to the alveolus and can be removed.
This explains why the PHYSICS FORCEPS, with its steady unrelenting trauma to the periodontal ligament, quantitatively creates a greater release of hyaluronidase in a shorter period of time than traditional forceps or elevators extractions because the trauma from those techniques is intermittent. Hence the use of PHYSICS FORCEPS is more efficient, faster and less traumatic to the alveolar bone.

Physics Forceps are innovative instruments useful for achieving atraumatic extractions. Its unique design delivers a powerful mechanical advantage by employing an efficient first-class lever.
The Physics Extraction Technique significantly reduces time and stress for your patients and for yourself. Additionally, you dramatically improve your patients economics.
With Physics Forceps you can:
-
Achieve atraumatic extractions in seconds, not minutes.
-
Extract most teeth (except lower third molars), in generally any condition.
-
Offer patients a breakthrough in the standard-of-care for exodontia
-
Reduce post-operative discomfort and patient healing time
-
Convert a refer-out procedure to a highly efficient in-house procedure.
-
Retain more patients, and eliminate surgical extractions
-
Effectively preserves the avelor ridge in preparation for immediate-load implants
-
Improve patient care
-
Improve patient acceptance
