interdental space packer

Abstract

The invention discloses a diastema packer. The diastema packer is prepared from an elastic material, is in a shape of like straight triangular prism and comprises an upper surface, a lower surface andthree side faces, wherein the upper surface and the lower surface are parallel to each other and are congruent; the three side faces are perpendicular to the upper surface and the lower surface; lateral edges of the three side faces are identical, are parallel to one another and are perpendicular to the upper surface and the lower surface; the three side faces are cylindrical surfaces depressed towards the inner part of the packer; three sides of the upper surface and three sides of the lower surface are in circular arc shapes; in addition, side edges, crossed relative to two side faces, of two side faces are symmetrically distributed; besides, circular arc lengths of the two side faces are identical and are both 3 to 8mm, the circular arc length of another side face is 2 to 8mm and the heights of the lateral edges are 6 to 12mm. The diastema packer disclosed by the invention can prevent an impression material from entering diastema when the impression material enters an oral cavity,so that the hardened impression material is conveniently taken out; the diastema packer also can be used as an auxiliary fixing tool for coffer dam, a matrix band and the like; the generality of the diastema packer is improved and the sensitivity of clinical operation is reduced.

Description

technical field [0001] The invention belongs to the technical field of dental instruments, and in particular relates to an interdental space packing device. Background technique [0002] Oral impression (impression) refers to the negative model of the relevant oral tissues, reflecting the soft and hard tissues of the oral cavity related to restoration. Pour the model material into the prepared impression to obtain a model that is completely consistent with the shape of the inner surface of the oral cavity. The production of all kinds of oral restorations generally needs to prepare the impression, pour the model, and then make it on the model. Therefore, the quality of the impression model is closely related to the accuracy of making a good restoration. It can be said that the impression The quality of cast and model is the first prerequisite for making good restorations. Impression technique refers to the operation technique of making a negative mold of oral cavity tissues...
