Adjustable dental assembly with rotatable mirror

Abstract

A stable dental mirror assembly that is used by dentists during the treatment of patients is described. The mirror is fixed on a rubber dam frame that is placed in the patient's mouth during treatment. The dental mirror includes a handle on which the mirror slides. The handle includes an elbow curve. In further aspects, a method for using a dental mirror assembly and a dental mirror assembly kit are described. The dental mirror may be moved through 360 degrees and does not need to be held, thus freeing the dentist's hands. Additionally, the dental mirror assembly provides a stable visual field and allows easy movement and adjustment of the mirror.

Further, as used herein, the words a, an and the like generally carry a meaning of one or more, unless stated otherwise. The drawings are generally drawn to scale unless specified otherwise or illustrating schematic structures or flowcharts.

(9) Furthermore, the terms approximately, approximate, about, and similar terms generally refer to ranges that include the identified value within a margin of 20%, 10%, or preferably 5%, and any values therebetween.

(10) Aspects of this disclosure are directed to a dental mirror assembly, a method for using a dental mirror assembly and a method for assembling a dental mirror kit.

(11) An overview of the dental mirror assembly of the present disclosure is given below. The present disclosure relates to a stable dental mirror which fixes to a rubber dam frame 102 (RDF) as shown in FIG. 1A-1E and FIG. 2-4.

(12) A holder 105 connects handle 103 to the RDF 102, wherein the holder 105 is configured to allow the handle to be moved laterally (proximally or distally) along the rubber dam frame 102 to adjust the mirror position within a patient's mouth. As shown in FIG. 2, the holder 205 includes a ball 207, which fits within a socket 210 of a corresponding sleeve 204 which holds the handle. The combination of ball 207 and socket 210 allow a dentist to adjust the position of the distal end of the handle by rotating and/or swivelling the ball within the socket. The sleeve 204 is configured to allow movement of the handle along the longitudinal axis of the sleeve, in order to adjust the depth that the distal end of the handle is inserted into the patient's mouth.

(13) The dental mirror assembly has a handle 103 with a 60-90 degree (elbow) curve 111 in the middle, where the handle is connected to a support structure (RDF) 102. The handle is inserted into a second holder (106, 406) having a ball 408 which is inserted in a socket 409 on the back of mirror (101, 401), as shown in FIGS. 1A and 4. The ball and socket combination allows 360 degree rotation of the mirror with respect to the handle and allows the mirror to swivel or tilt about the holder. The sleeve 106 is configured to move along a straight section of the handle 103 between the distal end of the handle 103 and the angle 111.

(14) The dental mirror assembly consists of one piece separate from RDF. After the application of the RDF, the mirror is attached to any side of the RDF by a holder. The RDF (see FIG. 1B-1D) is used to hold the mirror and a rubber dam sheet. The dental mirror would be attached to the rubber dam frame at a position which gives a good visual image of a tooth exposed through a hole in the rubber dam sheet. FIG. 1E illustrates the rubber dam frame and rubber dam sheet inserted in a patient's mouth to isolate the tooth from the mouth.

(15) The ball/socket attachments allow 360 degree movement of the mirror and 180 degrees movement of the handle.

(16) In a non-limiting example, the handle may be about 12 cm long with a curve at the middle. The curve is 60-90 degrees, preferably 70-80 degrees, even more preferably 75 degrees.

(34) The handle may constructed of flexible material such that the angle of the curve is adjustable. For example, the handle may be made of nickel titanium, which has the property of shape memory. Alternatively, the handle may be non-adjustable.

(35) The second embodiment is shown in FIGS. 1A-1E and 2-4. The second embodiment is drawn to a method for using a dental mirror assembly comprising clipping, by a clip configured to at least partially surround a rubber dam frame 102, a first holder 105 to the rubber dam frame and connecting the first holder to a proximal end 120 of a handle 103, wherein the handle has a bend 111 between the proximal end 120 and a distal end 122; attaching a mirror 101 to the distal end of the handle by a second holder 106; adjusting the position of the mirror by moving the handle within the first holder and moving the mirror within the second holder.

(36) As shown in FIG. 2, the method further comprises connecting the first holder to the handle by inserting the proximal end 120 of the handle into a first sleeve 204 of the first holder, the first sleeve including a first socket 210 radially located at the center of the sleeve 204; inserting a first ball 207 radially located at the center of the clip into the first socket 210. The method includes adjusting the position of the mirror by at least one of sliding the handle within the first sleeve, rotating the handle within the first sleeve, swiveling the ball within the socket, and rotating the socket with respect to the rubber dam frame.
