The Posterior Physics Forceps set will allow you to extract erupted third molars (wisdom teeth) and what we call “hard to reach” second molars that you may not be able to access with the Standard Physics Forceps set of instruments. You will generally be able to access second molars with our Standard set of instruments, but with some patients the access can be difficult. As a result, the Posterior Physics Forceps set is designed specifically for the posterior regions of the mouth.
The Physics Forceps are a unique type of extraction system that provides:
Predictable and efficient extractions in less than four minutes
Atraumatic extractions where you preserve the bone
Elimination of root tip fractures
No need for elevating or laying a flap
Very little operator movement (or strength) necessary
The unique design of the Physics Forceps allows for light but constant pressure to be applied to the tooth which leads to chemical changes in the PDL and subsequent release of the Sharpey’s fibers. Once the tooth releases, it can be removed simply with a rongeur or even just your fingers.
Posterior Physics Forceps Set Includes
Four (4) Physics Forceps Instruments, plus a Distal Elevator
Upper Right – Teeth #1-2
Upper Left – Teeth #15-16
Lower Right – Teeth #31-32
Lower Left– Teeth #17-18>
About the Physics Forceps
The Physics Forceps are an innovative design that provides a simple mechanical advantage by employing first-class lever mechanics. Utilizing the patented “beak and bumper” technique, you can simply and predictably extract virtually any tooth in any condition, while preserving the buccal bone and socket. The beak of the Physics Forceps is designed to apply controlled pressure parallel to the long axis of the root. The bumper acts as a simple fulcrum or pivot point. While traditional instruments grasp, squeeze and twist, the Physics Forceps employs a slow, steady force that releases the tooth from the alveolar bone.
Why the Physics Forceps Are So Effective
By combining the biomechanical advantages of a first-class lever with the biochemical reaction that is occurring, extracting teeth has never been easier than with the Physics Forceps. When the periodontal ligament is traumatized with forceps or elevators, hyaluronidase is released. 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. This is what makes the Physics Forceps more efficient, faster, and less traumatic to the alveolar bone.
Preserving the Bone
By utilizing the Physics Forceps Technique (no squeezing, applying constant steady pressure with the wrist only and using the bumper as a pivot/fulcrum), it is uncommon to break the buccal bone or cortical plate. Think of the Physics Forceps as an elevator – all you want the instrument to do is move the tooth 1-3mm through constant steady pressure allowing the PDL to separate from the tooth. Once this chemical breakdown of the periodontal ligament by hyaluronic acid is sufficient, the tooth elevates coronally. You are now finished with the Physics Forceps. You can deliver the loose tooth with a traditional instrument. Also, the bumper is a compressive force that is holding the bone in place. Even though you are not squeezing, it is supporting the bone.
(For Upper Molars Only) - use the Distal Elevator (included in your kit) to separate the distal bone (including the tuberosity) for the tooth.
Use a flame-shaped diamond bur (GMX Flame Shaped Diamond G701 or G702 from Golden Dental Solutions) to drill a trench on the lingual side of the tooth (at the expense of the tooth) just below the gumline to secure a solid purchase point with the beak.
Upper Molars - with the handles opened wide place the bumper on the buccal surface at or about the mucogingival junction. Lower Molars - Place the beak first, then the bumper.
Set the beak into the depth of the lingual sulcus as far as possible on solid root surface. A secure purchase point on solid root surface is critical.
Using wrist movements only, apply constant steady pressure towards the buccal. Once you see the tooth move 1-3mm, you are finished with the Physics Forceps. Now deliver the tooth with a traditional instrument.
