Dental fulcrum wrench

A dental wrench device to loosen and extract teeth, comprising:

• a handle shaped to fit substantially inside a hand;
• one end of said handle terminating in a fixed tapered jaw with a sharpened edge configured to position along the tooth roots of a selected tooth below the gum line;
• a moveable jaw coupled to said handle;
• said moveable jaw having a contoured surface configured to grasp supporting gum and bone in which said tooth roots are embedded at a level below the crown of said selected tooth;
• wherein said jaws are configured with a dog leg bend in either or both of said fixed or adjustable jaws configured to prevent trauma to the lips of a patient when said device is positioned for the extraction of molar teeth;
• a jaw movement interface mounted in said handle, wherein operating said jaw movement interface moves said moveable jaw relative to said fixed tapered jaw;
• wherein when said fixed tapered jaw is positioned along the surface of a selected tooth, and said moveable jaw is positioned with said contoured surface grasping said supporting gum and bone in which said tooth roots are embedded, said moveable jaw may be locked into position;
• said device configured so that when said fixed tapered jaw is positioned along the surface of a selected tooth, and said moveable jaw is positioned with said contoured surface grasping said supporting gum and bone in which said tooth roots are embedded, then application of force to said handle will cause said device to act as a fulcrum applying force to said tooth to dislodge said tooth from the supporting gum and bone in which the tooth roots of said tooth are embedded;
• further comprising a back cap and a deformable lever made from a deformable material which deforms against said handle when excessive force is being used.

A method to loosen and extract teeth, comprising;

• applying a dental wrench device to a tooth to be extracted;
• said device comprising a handle shaped to fit substantially inside a hand;
• one end of said handle terminating in a fixed tapered jaw with a sharpened edge configured to position along the tooth roots of a selected tooth below the gum line;
• a moveable jaw coupled to said handle;
• said moveable jaw having a contoured surface configured to grasp supporting gum and bone in which said tooth roots are embedded at a level below the crown of said selected tooth;
• a jaw movement interface mounted in said handle, wherein operating said jaw movement interface moves said moveable jaw relative to said fixed tapered jaw;
• operating said jaw movement interface so as to position said fixed tapered jaw tightly along
• the tooth surface of a selected tooth, and so as to position the contoured surface of said moveable jaw so as to tightly grasp said supporting gum and bone in which said tooth roots are embedded;
• applying force to said handle in a direction to cause said device to act as a fulcrum which in turn applies force to said tooth to dislodge said tooth from the supporting gum and bone in which the tooth roots of said tooth are embedded;
• and extracting said tooth.
