Abstract

An Offset Tip Dental Elevator comprising a handle, an active elevating component (with a tip end and a rear end), a rigid connecting element interconnecting the handle and the elevating component, with a bend (having an inner curve and an outer curve) incorporated at the elevating component rear-end/rigid connection component junction point, wherein the handle and rigid connection element share the same longitudinal axis, the rear-end of the elevating component, the bend, connection element and handle all exist in the same plane, the longitudinal axis of the elevating component is different from the longitudinal axis of the handle-connection arrangement, and where the plane of the active elevating edge/surface(s) exist at an angle (preferably but not exclusively of 90 degrees) to the plane in which the bend-connection-handle arrangement exists. The elevating edge can be of current or future style, or may be provided as a luxating component.

Description

OFFSET TIP E EVATQR/LUXATOR

(RUSSELL SULLMAN- 10/02/04)

BACKGROUND

Dental elevators and luxators are dental tools used to loosen and displace teeth and tooth debris in the course of dental extractions. They are structurally similar, but differ according to the positioning of the active tip in operation.

Elevator function involves the insertion of the active elevating tip, carrying the active elevating surface and edge, into the inter-dental spaces between the mesial (front- facing) surface of the tooth to be extracted and the distal (rear-facing) surface of the adjacent tooth in front.

Luxator function involves the insertion of the active luxating tip, carrying the active luxating surface and edge, into the periodontal ligament space (i.e. the space containing the ligament between the tooth root surface and the bone to which the tooth attaches).

Current styles of elevators and luxators are comprised of an active tip and a handle, and a rigid connection between the tip end and the handle, characterised in that both the component parts (active tip, rigid connection and handle) and the plane of the active elevating or luxating surfaces exist in the same plane.

Current styles are difficult to use where there is a limitation of space, e.g. at the back of the mouth, so there is the need for a dental elevator/dental luxator that is designed for use where there is limited access.

DESCRIPTION AND TECHNICAL FEATURES

An Offset Tip Elevator comprising a handle, an active elevating edge having a tip end and a rear end, and a rigid connection between the handle and the rear end of the of the elevating edge, where there exists a bend between the elevating edge and the rigid connection.

The device is characterised by the following features: - 1. The elevating edge, bend, rigid connection and handle all exist in the same plane; 2. The rigid connection and the handle exist in-line with each other (i.e. they share the same longitudinal axis); 3. The longitudinal axis of the elevating edge component (i.e. from tip end to rear end) is different from the longitudinal axis of the connection-handle arrangement; 4. As the plane of the active elevating edge/surfaces exists at an angle, preferably of 90 degrees, to the plane in which the bend-connection-handle arrangement exists; 5. The plane of the active elevating surface is bisected by the plane in which the bend-connection-handle arrangement exists; The active elevator component may incorporate the features, parts and surfaces found in current or future styles of dental elevator. Dental luxators are special types of dental elevator, so they are substantially the same as elevators in general structure, with the difference being in the active functional tip. It is possible then, by the incorporation of the dental luxator elevating components, to make a Luxator form of the Offset Tip Elevator. The Offset Tip Elevator/Luxator will be hereinafter referred to as the 'invention'. The invention may incorporate more than one bend along its length, and be also thickened for strength and/or handling along part or all of the bend and or connection- handle. ♦ The rigid connection and/or handle may be rectilinear if desired. The arc of the concavity of the active el^'evatmg/luxating surface may exist in the tip end to rear end axis, or may exist in the side-to-side axis. The active elevating surface (i.e. that surface on the elevating tip that is placed against the mesial or front surface of the tooth to be extracted during operation) on the elevating tip of the invention exists on the opposite side of the plane of the active elevating surface to the connection-handle arrangement. This means that when in function the active elevating surface faces away from the teeth anterior to the tooth to be extracted, and faces away from the clinician.

The cutting edge of the active luxating tip may also be located on either side of the tip end to rear end axis (i.e. on the longitudinal sides of the luxating component/tip).

Detailed Description of examples of the Invention Figure 1 shows at (A) a Sullman Offset Tip Elevator 1 embodying the invention, with an active elevating tip 2, a bend 3, rigid connection 4 and handle 5. Figures 1(B), 1(C) and 1(D) provide views of the embodiment from each of the three mutually orthogonal directions X, Y and Z that are marked in 1(A). Figure 2 shows at (A) an embodiment of the invention when employed as a luxator, with an active luxator tip 6, a bend 3, rigid connection 4 and handle 5. Figures 2(B), 2(C) and 2(D) provide views of the embodiment from each of the three mutually orthogonal directions X, Y and Z that are marked in 1(A).

Figures 3, 4 and 5 show perspective views of a variety of different examples of the luxator manifestation of the invention. Figures 4 and 5 shows that the bend and rigid connection is thicker than the active tip for the purposes of structural strength.

Figure 6 shows a perspective view of another embodiment of the elevator form.

Figure 7 shows at (A) the characteristic and innovative features of the invention, wherein the common axis KL of the rigid connection 4 and handle 5 shares the same plane EFGH as the axis MN of the active elevating tip 2.

The axis of the tip MN is different from the connection-handle axis KL, and the plane ABDC of the active elevating tip surfaces is bisected by the plane EFGH containing the connection-handle axis.

The Figure 7(B) shows an enlarged view of the tip-bend-connection part of -the elevator shown in 7(A), illustrating the innovative active surface to connection-handle axis relationship being claimed for ( e. the plane of the active surfaces ABDC existing at an angle of more than 30 degrees to the plane EFGH containing the connection-handle axis).
