Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of tooth impression taking, and in particular relates to a tooth impression taking device. Background Art
[0002] Before teeth are manufactured, it is necessary to take impressions of the teeth. Currently, when taking impressions of teeth, the staff mix the paste mold and fill it on the impression tray, then insert the impression tray together with the paste mold into the patient's mouth, embed the teeth into the paste mold, and form an impression after the paste mold solidifies. However, when taking impressions of the upper teeth, the incisors of the upper teeth protrude outward at an inclined angle instead of being arranged vertically downward. When the paste mold is moved up to embed the teeth into the paste mold, the trajectory of the bottom end of the incisors is in front of the trajectory of the tail end of the teeth when the inclined outward teeth move relative to the paste mold. A certain amount of gap will be formed on the outside of the incisors, making it difficult for the paste mold to accurately impression the sides and details of the incisors, affecting the impression effect of the teeth. Utility Model Content
[0003] The utility model provides a tooth manufacturing and taking impression device, which has the characteristics of being able to improve the impression taking effect on the front teeth and the gaps between the teeth.

[0005] Wherein, the top end of the holding handle is fixedly connected to a limiting guide roller, and the traction and extrusion flat strip is clamped between the main body of the tooth print taking tray and the limiting guide roller.
[0006] Among them, one side of the sliding adjustment buckle plate is fixedly connected with an external connection sleeve, and the inner wall of the external connection sleeve is slidably connected with an internal limit rod.

DETAILED DESCRIPTION
[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a tooth printing device, comprising a tooth printing tray body 1 and a gripping handle 11, the inner wall of the tooth printing tray body 1 is fixedly connected with an elastic extrusion sleeve 2, the inner wall of the elastic extrusion sleeve 2 is slidably connected with a traction extrusion flat bar 3, one side of the traction extrusion flat bar 3 is fixedly connected with a traction connecting rope 31, the other end of the traction connecting rope 31 is fixedly connected with a sliding adjustment buckle plate 32, and the sliding adjustment buckle plate 32 is slidably connected to the top of the gripping handle 11.
[0017] In this embodiment: the staff fills the tooth impression tray body 1 with the mixed paste mold, then inserts the tooth impression tray body 1 together with the paste mold into the patient's oral cavity upwards, and lifts the tooth impression tray body 1 to embed the teeth into the paste mold. After the paste mold in the tooth impression tray body 1 is pressed onto the patient's upper teeth, the staff presses the sliding adjustment buckle plate 32 with their fingers to drive the traction connecting rope 31 to move, and the sliding adjustment buckle plate 32 slides on the holding handle 11. The sliding adjustment buckle plate 32 is connected to the holding handle 11 through the sliding rail groove, and the traction extrusion flat bar 3 is pulled by the sliding adjustment buckle plate 32 to move. The inward contraction of the traction extrusion flat bar 3 can drive the elastic extrusion sleeve 2 to deform and move inward, thereby squeezing the paste mold in the tooth impression tray body 1, so that the paste mold located on the outside of the front teeth can be tightly pressed. The tooth impression tray body 1 is a dental impression tray body 1 having a plurality of teeth, and the plurality of teeth are provided with a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are provided with a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are a dental impression tray body 1 having a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are a dental impression tray body 1 having a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are a dental impression tray body 1 having a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are provided with a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are provided with a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are provided with a plurality of teeth impressions. The plurality of teeth impressions tray bodies 1 are provided with a plurality of teeth impressions.
[0018] The top end of the holding handle 11 is fixedly connected to a limiting guide roller 12, and the traction and extrusion flat strip 3 is clamped between the tooth print tray body 1 and the limiting guide roller 12; by setting the limiting guide roller 12, the traction and extrusion flat strip 3 can be limited, so that the traction and extrusion flat strip 3 can slide in contact with the side wall of the tooth print tray body 1, avoiding the traction and extrusion flat strip 3 from expanding outward and occupying too much space, so that the device can be more conveniently inserted into the patient's oral cavity, and the limiting guide roller 12 is connected to a roller sleeve for rotation on the outside of the limiting column. When the traction and extrusion flat strip 3 is pulled, the traction and extrusion flat strip 3 rubs against the roller sleeve on the outside of the limiting guide roller 12 to rotate, thereby reducing the resistance of the traction and extrusion flat strip 3 during movement.
[0019] The outer limit rod 34 is inserted into the limit hole 4, and the outer limit rod 34 and the limit hole 4 are used to limit the outer limit rod 34, thereby limiting the position of the sliding adjustment buckle plate 32.
[0020] A limit hole 4 is provided at the top of the gripping handle 11, and an inner limit rod 34 is inserted into the limit hole 4; by setting the limit hole 4, the sliding adjustment buckle plate 32 can be limited in cooperation with the inner limit rod 34, the limit hole 4 passes through the gripping handle 11, and the diameter of the limit hole 4 is larger than the diameter of the inner limit rod 34, so that when the inner limit rod 34 is located above the limit hole 4, the inner limit rod 34 can smoothly fall downward under the action of gravity to be inserted into the limit hole 4.
[0021] A lubricating gasket 5 is fixedly connected to the inner wall of the elastic extrusion sleeve 2, and the width of the traction and extrusion flat strip 3 is smaller than the width of the elastic extrusion sleeve 2; by arranging the lubricating gasket 5, the friction between the elastic extrusion sleeve 2 and the traction and extrusion flat strip 3 can be reduced, so that the movement of the traction and extrusion flat strip 3 is smoother, and the width of the elastic extrusion sleeve 2 is larger than the width of the traction and extrusion flat strip 3, so that when the traction and extrusion flat strip 3 extrudes the middle part of the elastic extrusion sleeve 2, the middle part of the elastic extrusion sleeve 2 moves toward the inside of the tooth impression tray body 1, and the positions on both sides can be directly deformed, providing a margin for the movement of the elastic extrusion sleeve 2. When the movement distance of the elastic extrusion sleeve 2 is small, the resistance to the deformation of the elastic extrusion sleeve 2 itself is small, thereby reducing the resistance to the extrusion of the elastic extrusion sleeve 2 by the traction and extrusion flat strip 3.
[0022] The working principle and use process of the utility model are as follows: the staff fills the tooth impression tray body 1 with the mixed paste mold, then inserts the tooth impression tray body 1 together with the paste mold upward into the patient's oral cavity, and lifts the tooth impression tray body 1 to embed the teeth into the paste mold. After the paste mold in the tooth impression tray body 1 is pressed onto the patient's upper teeth, the staff presses the sliding adjustment buckle plate 32 with their fingers to drive the traction connecting rope 31 to move, and the sliding adjustment buckle plate 32 slides on the gripping handle 11 until the position of the inner limit plug rod 34 corresponds to the position of the limit plug hole 4, and the inner limit plug rod 34 falls and is inserted into the limit plug hole 4 under the action of gravity, and the inner limit plug rod 34 is adjusted by sliding The buckle plate 32 pulls the traction and extrusion flat bar 3 to move. The inward contraction of the traction and extrusion flat bar 3 can drive the elastic extrusion sleeve 2 to deform and move inward, thereby squeezing the paste mold in the tooth impression tray main body 1, so that the paste mold located on the outside of the incisors can fit closely with the patient's teeth, fill the gap between the teeth and the paste mold, and fill part of the paste mold in the tooth gap, thereby improving the effect of taking impressions of the incisors and the tooth gap. After the traction and extrusion flat bar 3 and the elastic extrusion sleeve 2 complete the position adjustment of the paste mold, the staff manually stabilizes the position of the tooth impression tray main body 1 and the paste mold until the paste mold solidifies, and then the staff takes the tooth impression tray main body 1 out of the patient's mouth.
