Detailed Description

The utility model is described in further detail below with reference to the figures and the detailed description.

As shown in fig. 1 to 4, a disposable digital denture tray comprises a tray main body 1 and a tray handle 2, wherein the tray handle 2 is connected to the tray main body 1; the end part of the tray handle 2 close to the tray main body 1 is provided with a through hole 3 or a gap 5, and the two sides of the through hole 3 form a connecting rib 4 which is easy to break. When the handles of the upper and lower jaws are removed, the tray handle 2 can be broken off from the connecting rib 4 or the gap 5 by only holding the tray main body 1 with one hand and holding the tray handle 2 with the other hand and applying pressure perpendicular to the tray handle 2, so that the tray handle 2 is separated from the tray main body 1.

Tray main part 1 and tray handle 2 are by plastics integrated into one piece, through moulding plastics alright with tray main part 1 and tray handle 2 integrated into one piece. The through holes 3 that the tray handle 2 is close to the tip setting of tray main part 1 are two, as shown in fig. 1 and fig. 2, the splice bar 4 that the both sides of two through holes 3 formed is three, and through hole 3 is semi-circular through-hole, and the opening of semi-circular through-hole is close to tray main part 1. Stress concentration area is preset at the junction of tray handle 2 and tray main part 1 (be connecting rib 4) for tray handle 2 is broken easily in connecting rib 4 department.

The two sides of the end part of the tray handle 2 close to the tray main body 1 are respectively provided with a notch 5, as shown in fig. 3 and fig. 4, a stress concentration area is preset at the connecting part of the tray handle 2 and the tray main body 1 (namely, the part between the notches 5 at the two sides), so that the tray handle 2 is easy to break at the notch 5.

After the tray handle 2 is broken off from the tray main body 1, the broken area forms a certain concave edge on the outer side wall of the tray main body 1, a small amount of flanges can be formed on the outer side wall of the tray main body 1, the edges of the small amount of flanges are easy to trim, and the trimming time is greatly reduced.

The tray body 1 is provided with a plurality of overflow holes 6, and the impression material can overflow from the overflow holes 6, thereby being beneficial to retention. When the tray main body 1 is an upper jaw tray main body, one end of the tray handle 2 far away from the tray main body 1 faces downwards when in use; when the tray main body 1 is a mandible tray main body, one end of the tray handle 2 far away from the tray main body 1 is upward when in use. The tray handle 2 forms an L-shaped handle, the L-shaped handle is downward when the upper jaw is used, the L-shaped handle is upward when the lower jaw is used, and the influence on the lip muscle is avoided when the mold is taken. The lip side flange of the tray main body 1 is short and has a width of 3-5 mm. When the tray main body 1 is a lower jaw tray main body, the lower jaw tray main body is extended outwards (extended towards the lower jaw hyoid muscle) towards the back lower direction close to the back edge of the lingual side, as shown in an extended part 8 of fig. 2 and 4, and the obtained model is well extended, so that the retention is facilitated. The tray shape of the tray body 1 matches the jaw form from the sagittal direction and the lateral direction. Finger supports similar to the tooth arrangement wax dike are arranged on the surface of the tray main body 1, so that the lip, cheek and tongue muscles are in natural and comfortable positions during mold taking. The upper and lower jaw female molds are prepared, and the female molds are fully extended by pressing fingers on the finger supports 9, so that the female molds can be conveniently occluded vertically.
