Description
Technical Field
The invention belongs to the technical field of dental instruments, and particularly relates to a dental space packer.
Background
The impression of the mouth (impression) is a negative mold of the tissues related to the mouth, reflecting the condition of soft and hard tissues of the mouth related to the repair. The model material is poured into the prepared impression to obtain a model completely consistent with the shape of the inner face of the mouth. The making of various oral cavity restorations generally needs to prepare an impression, fill a model and then make on the model, so that the quality of the impression model is closely related to the accuracy of making an excellent restoration, and the quality of the impression and the model is the first prerequisite of making an excellent restoration. Impression technique (impression technique) is an operation technique for making a negative mold of the relevant tissue of the oral cavity by impression material (impression material) and impression tray (impression tray) in a clinical restoration operation.
In the oral clinical operation, when taking the female die in a patient's mouth, the impression material can enter undercut areas such as interdental spaces, and after the impression material is hardened, the tray and the impression material are required to be completely taken out, but the impression material which enters the undercut areas such as interdental spaces is also hardened, so that the female die and the tray are difficult to take out.
In the past, doctors put cotton into the dental spaces to prevent the impression material from entering, but the problems such as softness, inelasticity, easy carrying-out, rough surface and the like are not solved due to the limitation of the cotton material.
The problems appear in clinic, firstly, the tension of the patient is aggravated, and the discomfort is increased; secondly, in order to take out the female die, the force is increased, the die is easily released, namely the die material is separated from the tray, at the moment, although the model is taken down, the model is invalid, the die needs to be taken again, and the female die is often unacceptable to patients. More serious, the patient's gum will be torn due to violent demoulding, which causes other medical problems.
In clinic, because the impression material is not taken out quickly, a plurality of problems occur, and the life of a patient is even threatened. One hospital in Zhejiang province appears: when a female die is made in the mouth of an obese patient, the impression material can not be taken down for a long time because the impression material enters undercut areas such as tooth gaps, and the patient can fall back to the tongue and have asphyxia reaction for rescue; one example appears in a hospital in Yunnan province: for the same reason, the impression material enters the trachea, causing the death of the patient.
Disclosure of Invention
The invention aims to solve the problems and provides a dental space packer which solves the technical problems of the prior art that the impression material enters the dental space to cause that the model is difficult to take out in time, and other medical problems are caused. In order to achieve the purpose, the invention adopts the following technical scheme:
the dental space obturator is characterized in that the obturator is made of an elastic material and is in a shape similar to a straight triangular prism, namely the obturator comprises an upper surface, a lower surface and three side surfaces, wherein the upper surface and the lower surface are parallel and congruent, the three side surfaces are perpendicular to the upper surface and the lower surface, the side edges of the three side surfaces are equal, parallel and perpendicular to the upper surface and the lower surface, the three side surfaces are cylindrical surfaces recessed towards the inside of the obturator, the three sides of the upper surface and the lower surface are circular arc-shaped, the two side surfaces are symmetrically arranged relative to the side edges intersected with the two side surfaces, the circular arc-shaped arc lengths of the two side surfaces are equal and are 3-8 mm, the circular arc length of the other side surface is 2-8 mm, and the height of the side edges is 6-12 mm.
Further, the elastic material is butyl rubber.
Further, the elastic material is nitrile rubber.
Furthermore, the included angle between the vertex of the upper surface and the connecting line of the other two points of the upper surface is less than 90 degrees.
Further, the intersection of the three side surfaces is rounded.
Compared with the prior art, the invention has the following beneficial effects:
the dental space packer can prevent an impression material from entering dental spaces when the impression material enters an oral cavity, so that the part of the impression material entering a concave inverted area is reduced, the impression material is convenient to take out after being hardened, and other medical problems are reduced; because materials such as rubber and the like can be trimmed, doctors can use tools such as ophthalmic scissors and the like to do personalized modification according to the size and the shape of the patient tooth space, and can also be used as auxiliary fixing tools of rubber barriers, forming sheets and the like, thereby improving the universality of the invention and simultaneously reducing the sensitivity of clinical operation.
Drawings
FIG. 1 is a schematic view showing the construction of an interproximal packer of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments, and the objects and effects of the present invention will become more apparent, and the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the interdental obturator of the present invention is made of an elastic material such as nitrile rubber or butyl rubber, and the shape thereof is like a straight triangular prism, that is, the obturator includes an upper surface, a lower surface and three side surfaces, wherein the upper surface and the lower surface are parallel and congruent, the three side surfaces are perpendicular to the upper surface and the lower surface, the side edges of the three side surfaces are equal, parallel to each other and perpendicular to the upper surface and the lower surface, the three side surfaces are all cylindrical surfaces recessed towards the inside of the obturator, the three edges of the upper surface and the lower surface are all circular arc-shaped, and wherein the two side surfaces are symmetrically arranged relative to the side edges where the two side surfaces intersect, the included angle between the vertex of the upper surface and the connecting line of the other two points of the upper surface is less than 90 degrees, and the intersection of the three side surfaces; the arc lengths of the two side surfaces are equal and are both 3-8 mm, the arc length of the other side surface is 2-8 mm, and the height of the side edge is 6-12 mm.
Clinical operation physicians can estimate the specific condition of the patient's interdental space by means of clinical direct observation, referring to oral cavity x-ray films, hand feeling when dental floss passes through the interdental space and the like, thereby selecting the interdental space obturator with corresponding shape and size.
Then, the doctor selects a corresponding shape according to the interdental condition of the patient, and uses tools such as an ophthalmic scissors to cut, and finally obtains a finished product with a proper shape and size.
The physician can use forceps to hold the device, gently place the device in the patient's interdental space, take care of the gentle movement to avoid damaging the adjacent periodontal tissues, examine the device with an oral mirror after the device is in place, and ask whether the patient is in place on the buccal (labial) and lingual sides, and ask whether the patient has pain, and slight distending pain is a normal phenomenon, and if the degree is heavier, the device should be taken out in time for adjustment.
Because of the high accuracy requirements on the shoulder in dental restorations, physicians generally do not place the obturators in the posterior mesial and distal spaces of the teeth to avoid affecting model accuracy.
After the physician takes the impression material together with the tray out of the patient's mouth, the interdental obturating apparatus is taken out by using forceps, a probe, dental floss and other tools in time.
The tooth space stuffer of the present invention may also be used as a wedge, i.e., an auxiliary fixture for the rubber dam and the shaping sheet, and may be used as a conventional wedge, in which the excess part is cut off after the wedge is in place.
In conclusion, the invention can prevent the impression material from entering into the dental clearance when the oral cavity female die is manufactured, thereby reducing the part of the impression material entering into the inverted concave area, facilitating the impression material to be taken out from the mouth of a patient and avoiding other medical problems; in addition, the invention can be used as a wedge and has the advantages of convenient operation, low cost and the like.
It will be understood by those skilled in the art that the foregoing is only a preferred embodiment of the present invention, and is not intended to limit the invention, and although the invention has been described in detail with reference to the foregoing examples, it will be apparent to those skilled in the art that various changes in the form and details of the embodiments may be made and equivalents may be substituted for elements thereof. All modifications, equivalents and the like which come within the spirit and principle of the invention are intended to be included within the scope of the invention.
