  • Patent number: 5904482
    Abstract: The tooth extraction device includes a pair of handle members with opposing jaws and a force limiting spring or biasing member interconnecting the handle members to provide an adjustable and selective force to be applied to a targeted tooth. A pin is mounted between the handle members and may be positioned so that more or less clamping force is exerted upon the tooth. The jaws of the handle members have contacting surfaces which surround a concave or recessed area, and the jaws have a curved shape enabling the jaws to effectively grasp teeth of different sizes and at different locations in the mouth. The method of the invention includes the steps of preselecting a desired amount of clamping force to be applied to the targeted tooth by choosing a first set point, engaging the tooth with the extraction device and, if desired, adjusting the amount of force applied to the tooth by selecting a different set point reflective of a different amount of clamping force.
