Extraction  simple, predictable and non-surgical


We have all experienced the “snapping” sound of a fractured root tip or having to remove bone to access a compromised tooth. These events can make extractions unprofitable, disruptive to the treatment schedule, stressful for our patients and challenging us .


PHYSICS FORCEPS is new trend in teeth extraction with different method  biochemically and bio-mechanically.


Biochemistry of tooth extraction :

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 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 hyaluronic acid, which is the cement substance of all human tissue.  Once this chemical breakdown of the periodontal ligament by hyaluronic acid 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 elevator 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.


Biomechanical differences between conventional extraction and PHYSICS FORCEPS :

Conventional Forceps  require two equal forces placed on the crown of a tooth, with a 3rd force (pulling with your arm) being necessary to extract the tooth.




The Physics Forceps require a stabilized class I lever rotating force which eliminates the need for the 3rd force (pulling with your



The Principles of Bio-mechanics is the basis for the development of the Physics Forceps.

Through the implementation of:

  • A Class 1 lever .
  • Creep – a phenomenon whereby a material  (in this case bone & PDL) continues to change shape over time under a constant load.
  • Stress    is the internal distribution of force per unit area that balances and reacts to external loads applied to a body.


How to use the physics forceps ?

One force is applied with the beak on the lingual aspect of the tooth or root. The second force is applied via the “bumper” which is placed on the alveolar ridge at the approximate location of the mucogingival junction (Figure 7). When it is critical to preserve the five walls of the socket, such as in immediate implant placement, special precautions can be taken such as reducing the buccal aspect of the tooth to be extracted a couple of mm with a diamond bur subgingivally and consider using a periotome prior to placing the forceps.

The handles of the Physics Forceps are not squeezed, just held, and a gentle but steady rotational force is applied through a small amount of wrist movement only. Then  apply a steady pressure in this position for about 1.5 – 2 minutes. As the instrument is allowed to do what it is intended to do, an element of “creep” allows the bone to slowly expand and the PDL to release. Once this occurs, the tooth will disengage and rise approximately 1 – 2 mm occlusally. The tooth is now hanging in the socket and can be delivered with a hemostat, rongeur or conventional forcep.


The benefits includes the following:

– achieving atraumatic extractions quickly and easily using the one-minute extraction technique.

– dramatically reduced operator and patient stress.

– applicable to almost all teeth and in any condition.

– almost elimination of the need for surgical flaps and the resultant bone loss.

– increases your confidence in dealing with difficult extractions.

– helps facilitate immediate placement of implants.

Once dentistry understands and experiences the PHYSICS FORCEPS technique of quietly and effortlessly waiting for this biochemical reaction to take place, the traditionally taught extraction methods will no longer be used in dentistry.
