Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
As shown in fig. 1, the present invention provides an oral adhesive taking-out apparatus 100 for assisting a medical staff in taking out an oral adhesive when a dental crown 101 of a dental prosthesis is inoculated to an implant or a dental prosthesis 200 (i.e., teeth) using the adhesive. Preferably, a recess 101a is provided on the dental crown 101 of the dental prosthesis, and the implant or dental prosthesis 200 is fixed in the recess 101 a.
Specifically, with continued reference to fig. 2 and 3, the oral cement removal device 100 includes a membrane 10, the membrane 10 having a first surface 11 and a second surface 12 opposite to each other, the first surface 11 being smooth for adhering to the outer surface of the dental crown 101. Preferably, the first surface 11 may be attached to the outer surface of the dental crown 101 by chemical bonding or nano-adsorption techniques. The second surface 12 is a rough surface, an adsorption unit 20 is arranged on the second surface 12, and the adsorption unit 20 is used for adsorbing redundant oral cavity binders. It can be understood that, by providing the adsorption unit 20, the film 10 is adhered to the dental crown 101 of the dental prosthesis, and after the dental crown 101 of the dental prosthesis is adhered to the tooth or the implant with the oral cement, the overflowed oral cement is directly adsorbed by the adsorption unit 20; then, the oral cavity adhesive is directly taken out through the membrane 10, so that the oral cavity adhesive is prevented from being adhered to the dental crown or the gum of a patient, the oral cavity adhesive is very convenient to take out, and the operation is simpler.
It should be noted that, in the present embodiment, the words "first end 13", "second end 14", etc. are used for a plurality of times, only for more clearly and completely describing the structure and technical solution of the diaphragm 10, and are not intended to limit the present invention.
The diaphragm 10 is substantially rectangular, although in other embodiments the diaphragm 10 may have other shapes, such as oval, etc.
The dental implant 200 has a neck 201 and a crown 202 opposite each other, and the membrane 10 has a first end 13 and a second end 14 opposite each other, the first end 13 being disposed adjacent to the neck 201 and the second end 14 being disposed adjacent to the crown 202. The adsorption unit 20 is disposed adjacent to the first end 13.
Further, the membrane 10 may be made of a fiber material. Of course, the material of construction of the membrane 10 may be selected according to clinical needs and patient conditions.
Specifically, the fiber material may be any one of a polyethylene material, a polyester material, a nylon material, or a silicone material. Of course, the above-exemplified materials are characterized by, for example, polyethylene film: the product has the characteristics of low tensile strength, large tensile elongation, good surface gloss, transparency, heat sealability and the like; polyester film sheet: the composite film is a high-molecular plastic film which has excellent comprehensive performance, is colorless and transparent, and has luster, rigidity, hardness and toughness; nylon membrane: the coating has the characteristics of toughness, good transparency, good luster, high tensile strength, high heat resistance, high cold resistance, high oil resistance, high organic solvent resistance, high wear resistance, high puncture resistance and the like, and is relatively soft and high in oxygen resistance; porous silica gel membrane: has a series of excellent characteristics of higher softness, hydrophobicity, oxidation resistance, physiological inertia, no adhesion with human tissues and blood, good biocompatibility, no toxicity, no odor, no carcinogenesis and the like.
The size of the membrane 10 may be set according to the size of the dental crown 101. In the present embodiment, since the height of the dental crown 101 is generally not more than 10mm, the height of the membrane 10 (i.e., the width of the membrane 10) may be set to 10 mm; since the edge of the dental crown 101 of the artificial tooth is generally located within 2mm under the gum, the width of the roughened surface is set to 2 mm. Of course, in actual use, the excess film 10 in height and width can be cut free to match the size of the corresponding dental crown 101.
As shown in fig. 3 and 4, the adsorption unit 20 includes a plurality of protrusions 21, and the plurality of protrusions 21 are distributed along a direction from the first end 13 to the second end 14.
Further, along the direction from the first end 13 to the second end 14, the heights of the plurality of protrusions 21 are gradually arranged. Namely: the heights of the plurality of protrusions 21 are sequentially arranged in an increasing or decreasing manner along the direction from the first end 13 to the second end 14.
In this embodiment, the heights of the plurality of protrusions 21 are sequentially and incrementally arranged along the direction from the first end 13 to the second end 14. I.e. the lower the height of the protrusions 21 near the first end 13, the higher the height of the protrusions 21 near the second end 14. Here, this is provided to facilitate the attachment of the oral cement (i.e. to facilitate the absorption of the oral cement by the bulge 21) and also to avoid that said bulge 21 invaginates into the inner side of the dental prosthesis crown 101, i.e. into said recess 101, thereby hindering the dental prosthesis crown 101 from seating, adhering to a tooth or abutment.
Preferably, the height of the protrusion 21 is set in proportion to the distance from the first end 13 along the direction from the first end 13 to the second end 14.
Further, the material of the protrusion 21 is the same as that of the diaphragm 10, and the protrusion 21 and the diaphragm 10 are provided with an integrated structure, so that the processing and manufacturing of the diaphragm 10 can be facilitated, and the production cost of the diaphragm 10 can be reduced.
In the present embodiment, the protrusions 21 are fiber protrusions. Preferably, the protrusions 21 are soft fibrous protrusions.
As shown in fig. 5, the present invention further provides a method 300 for removing oral cavity adhesive, wherein the method 300 for removing oral cavity adhesive is implemented based on the oral cavity adhesive removing device 100 described in the present invention; the method 300 for removing the oral adhesive comprises the following steps:
step S1, adhering the first surface 11 of the film 10 on the dental crown 101, the second surface 12 of the film 10 having the adsorption unit 20 being disposed away from the dental crown 200;
step S2, the dental crown 101 of the artificial tooth is mounted on the tooth or the implant by the oral cavity adhesive, and the oral cavity adhesive overflowing after the tooth or the implant is in place is absorbed by the absorption unit 20; and
in step S3, after the oral cavity adhesive is hardened, the film 10 is removed and the excess oral cavity adhesive is removed, thereby completing the removal of the oral cavity adhesive.
It can be understood that, compared with the mechanical scraping method, the method for taking out the oral cavity adhesive is convenient to operate, the oral cavity adhesive can be integrally stripped, and the taking-out efficiency is high; meanwhile, the oral cavity adhesive is prevented from stimulating and damaging periodontal tissues, the pain of a patient is effectively reduced, and the oral cavity adhesive has a wide application prospect.
Further, in the step S1, the first surface 11 of the film 10 may be adhered to the outer surface of the dental crown 101 by a chemical adhesive or a nano-adsorption technique.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
