Description

Dental Grinder {Grinder for Dental Clinic}

The present invention relates to a dental polishing machine, and more particularly, a dental polishing machine for polishing a predetermined portion of the tooth surface during a dental procedure, a horizontal frame and a pair of vertical frames each extending vertically from both ends thereof. A frame body comprising, a polishing member made of a metal sheet coated with a polishing material on a portion of the outer circumferential surface, support holders coupled to the outer circumferential surface of the vertical frame, and a handle connected to the horizontal frame or the support holder. It relates to a dental polishing machine that is configured to include.

In general, in the dentist orthodontic treatment when grinding the tooth surface between the teeth, orthodontic stripper having a sharp saw blade shape is mainly used.

As a conventional method using the orthodontic stripper, a method of marking a suitable thickness between the tooth and the restoring part with carbon paper and grinding the excess part is used. However, this method is inefficient and inaccurate because it has to continue to grind until the desired fitting (fit) surface comes out, and there is a problem that the procedure cost is increased because frequent rework occurs.

In addition, the conventional stripper has a problem that is very likely to hurt the lips, or hurt the tongue.

Thus, metal filing strippers have been used to solve these problems. However, since the metal filing stripper has a very thin thickness of the strip, the user has to hold both ends of the strip with both fingers, and when the crown treatment site is a posterior part, there is a problem that both fingers are not easily inserted deeply into the oral cavity. In addition, the patient has to open his mouth wide, which is followed by pain.

Therefore, there is a high need for a dental instrument of a specific structure that can solve the above problems and is easy to use.

The present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

That is, the purpose of the present invention is a dental polishing machine for polishing a predetermined portion of the tooth surface during the dental procedure, it is easy to use and reduce the discomfort of the patient and the operator, while having a specific structure of the dental can reduce the cost of dental treatment It is to provide a polishing machine for.

Dental grinder according to the present invention for achieving this object, as a dental grinder for polishing a predetermined portion of the tooth surface during the dental procedure,

A frame body including a horizontal frame and a pair of vertical frames each extending vertically from both ends thereof, the frame body having a planar '-' shape;

An abrasive member comprising a metal sheet coated with a portion of an outer circumferential surface of the abrasive material and mounted between the vertical frames;

Support holders fixedly supporting both ends of the polishing member, each of which is coupled to an outer circumferential surface of the vertical frame; And

A handle connected to the horizontal frame or support holder for handholding or engagement with another dental tool;

It is configured to include.

Therefore, the dental polishing machine according to the present invention is because the abrasive material is thinly coated on a part of the outer peripheral surface of the polishing member made of a metal sheet, it is possible to easily polish the tooth between the narrow tooth and the tooth.

In addition, since the polishing member is made of a metal sheet, it is easy to handle in the oral cavity, and the frame body consisting of a horizontal frame and a vertical frame fixes the polishing member in a stable structure through a support holder, thereby preventing shaking of the polishing machine during use. The tooth surface can be polished more stably.

The part where the polishing material is coated on the outer circumferential surface of the metal sheet may be selectively changed as necessary, for example, may be formed in whole or in part on the outer circumferential surface of the metal sheet.

The handle may be selectively connected to the frame body or the holder for support as a position that is easily held and used by the operator during the polishing operation of the tooth surface. For example, the handle may be integrally formed in the holder for one side support in parallel to the horizontal frame so as to be convenient to polish the tooth surface moving in the left and right directions when grinding between the posterior teeth located deep inside the oral cavity. have.

As another example, the handle wraps around the central portion of the horizontal frame perpendicular to the horizontal frame so that when the tooth surface of the anterior tooth located in the oral cavity is polished, it may be convenient to move the teeth in the vertical direction. Can be combined.

In addition, the structure of the dental grinder in which the connection of the handle to the horizontal frame is horizontally coupled may be used for the polishing operation. The structure of the dental grinder in which the connection of the handle to the horizontal frame is vertically coupled is a grinding type. It can be preferably used for holding.

The combination of the polishing member and the support holder is not particularly limited as long as it is a structure capable of solidifying the mutual bonding force while maintaining each shape, and is preferably polished so that deformation of the thinner polishing member can be minimized. The member and the support holders can be joined by welding.

On the other hand, the handle may be used manually by the operator's hand, but may be formed into a structure that can be automatically coupled to the dental handpiece to operate the polishing member for polishing the tooth surface. For example, the handle may be formed of a hollow fastening structure in which an opening is formed at one side to mount the handpiece.

Preferably, the polishing member is appropriately adjusted in thickness so as not to apply excessive force to the teeth while polishing a predetermined portion of the tooth surface between the teeth. If the thickness of the abrasive member is too thick, the tooth surface may be over-grinded, and the force may be excessively applied to the tooth, thereby damaging the tooth. On the contrary, if the thickness is too thin, it is difficult to expect a desired polishing effect. Since the abrasive member may be broken, the thickness of the abrasive member is preferably selected within the range of 0.1 to 0.2 mm.

In one preferred embodiment, the polishing member is composed of a first portion of the polishing material is applied to a predetermined thickness, a second portion that is thicker than this, and an uncoated portion of the polishing material is not applied, The first portion is formed below the second portion, and may have a structure in which the uncoated portion may be preferentially introduced into the polishing portion and positioned on an opposite side of the horizontal frame.

In general, the space between the teeth into which the abrasive member is introduced is formed in a structure in which the space becomes narrower from the gum part toward the outside, so that the abrasive member for polishing the tooth surface between the teeth from the tooth surface to the external tooth surface of the gum part. It is desirable to have a thicker thickness. Therefore, when the abrasive member is introduced into the tooth surface between the teeth, the non-coated material, the first portion and the second portion of the polishing material are sequentially arranged in the direction from the tooth surface of the gum region to the external tooth surface. By forming the structure, the desired tooth surface can be easily polished corresponding to the space of the tooth surface.

In some cases, the lower end surface of the polishing member has an indentation structure of an elliptical shape in a vertical cross section, so that tooth surface polishing of a portion adjacent to the gum that requires little polishing of the tooth surface can be omitted, and the polishing process of the tooth surface is performed. The member may contact the gums to reduce the likelihood of damage to the gums.

As another preferred example, the abrasive member may be composed of three or more abrasive material application sites in which the abrasive material is spaced apart from each other at a predetermined interval.

Therefore, since the abrasive member is coated with the abrasive material is spaced at predetermined intervals, it is possible to selectively polish the tooth surface portion, if necessary, it is possible to minimize the over grinding of the tooth surface.

In addition, the abrasive material coating parts may be made of three or more, if necessary, for example, the abrasive material has a height of 1 mm to be formed in a strip shape applied to three parts of the metal sheet at 0.5 mm intervals. Can be.

The polishing material is not particularly limited as long as the material is coated on a portion of the outer circumferential surface of the metal sheet to easily polish the tooth surface, and preferably, may be made of diamond powder, and more preferably, 10 to 120. It may be made of diamond powder having a particle diameter.

Since the frame body has a vertical frame extending at both ends of the horizontal frame, and a polishing member is coupled between the vertical frames, the frame body is inserted into the oral cavity, so that the tooth surface polishing operation can be easily performed. The vertical frame may be shorter than the frame, and the ratio of the length of the horizontal frame to the length of the vertical frame may be 3: 2, which is a more structurally stable ratio.

In addition, a predetermined space is formed between the horizontal frame and the opposing surface of the polishing member, so that the polishing member mounted between the vertical frames has a predetermined rigidity and a predetermined flexibility. The flexibility of the polishing member may allow the tooth surface to be naturally and easily polished without excessive force being applied to the tooth when the tooth surface is polished. Therefore, the length of the vertical frames and the height of the polishing member may be, for example, a ratio of 5: 2 so that a predetermined space is formed between the horizontal frame and the polishing member.

On the other hand, the frame body is fixed so that the support holder and the polishing member stably, so that it can be easily handled in the oral cavity, so as not to hurt such areas even when touching the skin tissue and tongue in the oral cavity, for example For example, the corner portion of the frame body may have a rounded structure.
