Abstract
A dental forceps for removal of rear molars having first and second handles which are pivotally connected. Forward distal ends of the handles terminate, respectively, in a first handle support with an end most pad exhibiting a three dimensional and rounded surface profile extending laterally to one side, as well as a second handle terminating in a correspondingly angled beak. The arrangement of the pad and beak are such that, upon setting in position at the desired molar by placing the rounded and width extending pad support upon the gum of the patient between the molar and the cheek and concurrently placing the pointed beak on the lingual side of the molar, an outward rotating force is then exerted on the handles to roll (or rotate) the pad and beak such that the molar is forcibly extracted.
Claims
1. A dental forceps for dislodging of teeth, comprising: first and second handles which are pivotally connected and extend along a first linear axis; said first handle exhibiting an angled support at a distal end thereof extending in a second linear axis at angle relative to the first linear axis, a width extending pad at an end location of said angled support, said pad exhibiting a rectangular profile with a gum support surface, a centerline extending through a largest width dimension of said pad extending at a further angle relative to each of the first and second linear axes of said first handle; and said second handle exhibiting a beak extending outwardly from a distal end thereof and having an arcuate portion, said beak extending in a curved fashion relative to each of the first and second linear axes and terminating at a narrowed edge opposing and overlaying an intermediate location of said pad support surface when said handles are in a closed position; said pad adapted to being placed on one side of a tooth and, upon concurrently placing said terminating edge of said beak against an opposite side of the tooth, a rotating force exerted on said handles results in said pad acting as a fulcrum point around which said beak and terminating edge will move to forcibly dislodge the tooth.
2. The dental forceps as described in claim 1, said forceps being constructed of a medical grade steel.
3. The dental forceps as described in claim 1, each of said first and second handles having a generally elongated profile and further comprising a plurality of enhanced gripping portions.
4. The dental forceps as described in claim 1, said forceps being configured for removal of one of lower left, lower right, upper left and upper right located molars.
5. The dental forceps as described in claim 1, said first and second handles further comprising overlapping locations at a pivotal connection.

DETAILED DESCRIPTION OF THE INVENTION
(18) Referring to the Figures, wherein like numerals indicate like parts throughout the several views, four embodiments of a molar extraction forceps 20A-D are shown. The first, second, third, and fourth embodiments are used to extract a lower left molar, a lower right molar, an upper left molar, and an upper right molar, respectively.
(19) The first embodiment, shown in
(20) Each of the four embodiments include numerous common features and, for simplicity, those features set forth in each of the four embodiments will (unless otherwise specified) be commonly numbered and collectively referred to herein. Likewise, it should be appreciated that the lower left molar extraction forceps 20A and the lower right molar extraction forceps 20B are mirror images of each other, with the upper left molar extraction forceps 20C and the upper right molar extraction forceps 20D likewise being mirror images of each other.
(21) It should also be appreciated that each related variant of forceps 20A-20D is typically used to extract a second or third molar; however can be used to remove any tooth without departing from the nature of the present invention. The use and application of each variant of forceps to remove such as a molar or associated root tip is set forth further below. For purposes of this description, the term molar is further interpreted to include remaining root tip fragments with which the present invention is equally applicable in the removal of.
(22) Referring again to each of the related variants of
(23) Each of the handle shaped portions corresponding to the first and second members 26 and 28 further exhibit any desired surface profile which can include, but is not limited to, a scalloped or contoured portions 30 and 32 and which, in combination with the overall elongated but usually non-linear configuration of the handles, facilitates gripping and manipulation by the dentist or oral surgeon. Each of the elongate handles/members 30 and 32 is further bent such that a portion thereof extends along a first linear axis A (see selected variants of
(24) The first member 26 exhibits an integrally formed support 38 at a location forward of its hinged pivot point and approximate the distal end 24, whereas the second member 28 terminates in a pointed and multi-axial arcuate beak 40 extending in generally spaced apart and opposing fashion relative to the first handle support 38. The support 38 terminates at an end most three dimensional arcuate extending pad 34, which further exhibits an arcuate (or rounded/non-linear) surface profile and which extends laterally to one side of the handle 26 and integral support 38. By design, the pad 34 is intended to be complementary in configuration to the gum of a patient when inserted and manipulated by the user.
(25) The shaping of the pad 34 is further specifically illustrated at 34A, 34B, 34C and 34D in each of the enlarged distal end views of
(26) This configuration is best depicted in selected variants
(27) In use, the forceps 20 are set in position at the desired molar (not shown) by placing the rounded and width extending pad support 34 upon the gum of the patient between the molar and the cheek, i.e., the outside of the jaw and by concurrently placing the pointed beak 40 on the lingual side of the molar, i.e., on the inside of the jaw. An outward rotating force is then exerted on the handles 26 and 28 to roll (or rotate) the pad 34 and beak 40 such that the molar is forcibly extracted. The handles are further rotated about the offset and integrally extending support 38 to assist in extracting the molar.
(28) The configuration of the forceps 20, e.g., angles X, Y, Y1, and Z, advantageously provides a mechanical advantage to extract the molar in one piece by moving the forceps 20 in a simple rotational movement about the support 38. In addition to the rotational movement about the support 38, the forceps 20 can also be slightly twisted to aid in removal of the molar. Notably, and once the forceps 20 are set in position on the molar, the handles are not squeezed together to tighten the forceps 20 on the molar but rather are rolled to rotate (or in some instances to rock back and forth) the molar. In particular, it is desirous not to squeeze together the handles in order to avoid pinching gum/bone between the molar and the pad 30, as such pinching could limit or prevent the molar from rocking back and forth.
(29) As is shown in the various figures, the support 38 and the pointed jaw 40 extend in a generally offset angular direction than the first handle 26 and second handle 28. That said, it is also appreciated that the support 38 and the pointed jaw 40 can extend in any direction relative to the handles within the scope of the invention.
(30) By design, the selected angles X, Y, and Z incorporated into the design of the forceps are of a magnitude to provide a mechanical advantage when extracting the molar and to properly fit in the mouth of a patient. As is also shown, the magnitude of the angles X, Y, and Z of the lower molar extraction forceps 20A, 20B can be different than the magnitude of the angles X, Y, and Z of the upper molar extraction forceps 20C, 20D. This difference in magnitude can accommodate for different angles and locations of the upper and lower molars. It should also be appreciated that the angles X, Y, and Z can have a magnitude different than that shown in the various figures without departing from the nature of the present invention.
(31) The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. Obviously, many modifications and variations of the present invention are possible in light of the above teachings, and the invention may be practiced otherwise than as specifically described.
(32) Having described my invention, other and additional preferred embodiments are envisioned and without departing from the scope of the appended claims.
