By forming a relatively low step at the center of the lower surface, the impression material is discharged to the open central side of the lower surface in the process of ejecting the impression material while the dental impression material nozzle tip moves in a certain direction. Induces the discharge. On the other hand, by forming high steps on both side portions, it is possible to prevent a phenomenon in which unnecessary impression material is excessively ejected on the side surface portion other than the upper surface of the tooth.

According to one embodiment of the present invention, the central portion of the lower surface formed so as to have the step may include a straight section.

By forming the central portion of the lower surface so as to include the straight section, the impression material having a uniform thickness spreads from the impression material ejection portion to the rear portion in the moving direction, and the effect of forming a layer on the teeth uniformly is obtained. is there.

According to one embodiment of the present invention, the impression material ejection portion may have a structure including an upper surface, a lower surface, and both side surfaces connecting the upper surface and the lower surface, and the width on the left and right is longer than the height.

The impression material discharge portion in the present invention has a structure designed according to the width of the teeth and the required amount of the impression material applied. When the left and right widths are formed in a structure longer than the height and the left and right widths correspond to the tooth width, the impression material is flatter and evenly discharged onto the teeth compared to the conventional circular discharge part. Can achieve the effect.

According to one embodiment of the present invention, the width of the dilated opening is formed to a size corresponding to the width of the tooth, giving the impression that at least the entire width of the upper surface of the tooth is covered by one ejection on the tooth. Material can be discharged.

Conventionally, since the impression material ejection part is not formed in a size corresponding to the width of the tooth, the impression material is often ejected by applying it twice or three times on the tooth. There was a problem that led to material loss as well as time and effort. In addition, this has a problem that a skillful framework cannot be formed by forming a non-uniform coating layer.

However, in the case of the present invention, by forming the width of the dilated opening corresponding to the width of the tooth, it is possible to form a flat and uniform coating layer of impression material with only one discharge.

According to one embodiment of the present invention, the cross section of the dilated opening may have a width at the end of the dilated opening larger than the height.

As an example, the cross section of the dilated opening can be realized as an ellipse or rectangle whose horizontal axis length is longer than its vertical axis length.

According to one embodiment of the present invention, the width (W) of the end of the dilated opening may be 5 mm to 13 mm. As an example, the width of the end of the dilated opening may be 7 mm to 13 mm, or 5 mm to 10 mm. The width is preferably slightly larger than the width of the teeth, especially the molars. However, since the tooth size varies depending on the age, a preferable range can be determined within the above range according to the width of the applied tooth.

According to one embodiment of the present invention, the height (H) of the end of the dilated opening may be 4.0 mm to 5.5 mm. As an example, the height of the end of the dilated opening may be 4.2 mm to 5.5 mm, 4.0 mm to 5.2 mm. The height of the end of the dilated opening takes into consideration the height of the teeth, has the height of the end of the dilated opening in the above range, and the impression material flows to the left and right when the impression material is discharged, making it unnecessary. It has the effect of preventing the capacity used from increasing. The vertical and horizontal lengths of the dilated opening are closely related to the size of the tooth to which the impression material is applied. The impression material discharged from the dilated opening can be applied to the tooth, fixed so as to form a tooth mold, and cured to form a tooth mold.

Here, when the lengths of the vertical and horizontal longest axes of the cross section of the dilated opening are separated from the numerical range, too much or too little impression material is discharged at one time to obtain a uniform coating. There is a problem that is not formed.

In particular, the length of the left and right longest axes of the dilated opening is formed to be the same as or larger than the width of a general tooth. In this case, the practitioner who applies the impression material to the teeth has an effect that the impression material can be uniformly applied to the width of the teeth with only one ejection operation without repetitive work.

According to one embodiment of the present invention, the step (D) between the high step and the low step on the lower surface of the impression material discharge portion may be 1 mm to 2.5 mm.

The step between the high step and the low step is an important factor for determining the optimum discharge amount. Here, in the present invention, the step can be designed to have a slightly short length or a slightly long length in consideration of the angle at which the discharge portion is bent at the impression material introduction portion. As an example, the step may be 1 mm to 1.5 mm. As another example, the step may be from 1 mm to 2.0 mm. As a further example, the step may be 1.5 mm to 2.5 mm.
