Description

Gingival retraction coil with groove structure

Technical Field

The utility model relates to a preparation field that oral cavity dentistry was used, in particular to groove structure's gingival retraction coil.

Background

In the process of manufacturing the dental prosthesis, sometimes in order to obtain a better aesthetic effect, a dental crown is required to be prepared below a gum, and a gum retraction and retraction technology using a gum retraction and retraction line can avoid that a grinding head of a high-speed turbine damages gum tissues in the process of preparing the dental prosthesis, and the gum margin is exposed, the visual field is clear, and finally a good impression is obtained.

The gingival retraction line that uses in present oral cavity dental treatment is mostly woven for the cotton thread and forms, and adsorbs on the cotton thread has the liquid medicine, can reduce the oozing of blood in the gingival sulcus, gingival sulcus liquid when polishing the dental crown, but the not enough of existence is: when the grinding head arranged on the high-speed turbine is used for grinding, the turbine can spray a large amount of water mist to dilute the concentration of the liquid medicine absorbed in the gingival retraction line, and the gingival retraction line cannot have a clear view; to the novel special-shaped dental grinding mechanism of patent number CN204698711U, the pilot pin of the head of polishing that proposes in this specification can provide accurate location work, but this pilot pin point is too sharp, and the assembly carries out the easy damage patient's gum tissue when the tooth prepares on high-speed turbine, and easy and the winding of gum line of row when using this grinding mechanism, destroys the structure of row gum line. Aiming at an elastic gingival retraction coil with a patent number CN201642381U, the elastic closed coil provided in the specification can solve the problems of gingival retraction line bounce, material waste and cross infection in the operation process, but the material of the elastic closed coil is composed of cotton and spandex, so that water mist sprayed by a high-speed turbine cannot be isolated, and certain influence is brought to the use process of people.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide a gingival retraction coil with a recessed structure, which can effectively solve the problems of the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a gingival retraction coil of groove structure, includes the coil inner wall, the fixed surface of coil inner wall is connected with the recess, the fixed surface of recess is connected with the coil outer wall.

Preferably, the cross-sectional profile of the groove is a semicircular groove shape.

Preferably, the shape of the inner wall of the coil is a pattern structure.

Preferably, the material of recess is latex, and the appearance of recess is the ring shape.

Preferably, the cross-sectional view of the outer wall of the coil is semicircular.

Compared with the prior art, the utility model discloses following beneficial effect has: the gingival retraction coil with the groove structure has the following characteristics: the tip of the polishing head can not contact with the gingival retraction line, so that the gingival retraction line is prevented from being wound with the tip of the polishing head; the water mist and the air flow of the high-speed turbine directly overflow from the groove and are not in direct contact with gum tissues, so that the tissue damage and subcutaneous emphysema are reduced; the doctor can use the tips of the dental appliances such as a resin mixing knife, a glass ion mixing knife, a pressurizer, a probing and the like to be placed at the bottom of the groove, different positions at the gingival retraction coil add pressure slightly and can lay and target in place, latex gingival retraction coil longitudinal section is semi-circular structure, elasticity is big, convex structure is conveniently worn into, shorten the time of seeing a doctor, it is painful to reduce patient, the coil outer wall that sets up can also avoid fish tail gum soft tissue in the installation, the coil inner wall of design can increase the roughness of inner wall, this groove structure's gingival retraction coil has does not destroy gingival retraction coil structure, effectively keep apart the water smoke of high speed turbine injection, provide clear field of vision, reduce the gingival tissue damage, reduce the effect that patient damaged and reduce the infection, be favorable to people's use, whole gingival retraction coil of groove structure simple structure, and the operation is convenient, the effect of use is better for traditional mode.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a gingival retraction coil with a groove structure comprises an inner coil wall 1, a groove 3 fixedly connected to the outer surface of the inner coil wall 1, and an outer coil wall 2 fixedly connected to the outer surface of the groove 3.

Further, the cross-sectional view of the groove 3 is a semicircular groove shape, and the structure of the groove has the following characteristics: the tip of the polishing head can not contact with the gingival retraction line, so that the gingival retraction line is prevented from being wound with the tip of the polishing head; the water mist and the air flow of the high-speed turbine directly overflow from the groove and are not in direct contact with gum tissues, so that the tissue damage and subcutaneous emphysema are reduced; the doctor can use the tips of the dental appliances such as a resin mixing knife, a glass ion mixing knife, a pressurizer, a probing and the like to be placed at the bottom of the groove, and the dental appliances can be placed in place by slightly pressurizing different parts of the gingival retraction coil.

Furthermore, the shape of the coil inner wall 1 is a pattern structure, the pattern is not limited, and the roughness of the inner wall can be increased.

Further, the material of recess 3 is latex, and the appearance of recess 3 is the ring shape, can design disposable or through the used repeatedly of disinfecting according to different needs.

Furthermore, the cross section of the outer wall 2 of the coil is semicircular, so that the possibility of scratching soft tissues of gums in the installation process is avoided.

The utility model discloses theory of operation and use flow: when the gingival retraction coil with the groove structure is used by a doctor, the doctor can clean and insulate wet an affected tooth firstly, then select the latex retraction coil matched with the depth of an affected gingival sulcus, the doctor uses the resin mixing knife, the glass ion mixing knife, the pressurizer, the probing and the like to place the tips of dental appliances at the bottom of the groove, slightly pressurize to the free ends of the inner wall 1 of the coil and the outer wall 2 of the coil to be flush with the gingival margin in the direction of the tooth root around different parts of the neck of the tooth body, so as to smoothly protect the retraction coil, finally, the retraction coil needs to be stored for 5 to 10 minutes before obtaining impression materials, the form stability of the gum is maintained, when the retraction coil is temporarily separated from the tooth surface, the operation of taking the retraction coil of the latex retraction coil can be taken out, the effects of not damaging the structure of a retraction cord, effectively isolating water mist sprayed by a high-speed turbine, providing a clear visual field, reducing damage of gum tissues, reducing the damage, is beneficial to the use of people.
