Definitions
- the invention relates to a dental grinding body for treating a constriction of teeth, which can be inserted into the interdental spaces and is provided on both sides with opposing work surfaces and which has a shaft for attachment to a linear actuator.
- One method of treating a crowding of teeth is to remove the rotations using a fixed or removable appliance.
- the recurrence rate is relatively high.
- a dental grinding body which is horizontal, ie. H. is introduced transversely to the longitudinal direction of the teeth by means of a horizontal abrasion movement to remove tooth substance in the interdental contact area. This creates space between the teeth.
- a disadvantage of the use of these known dental abrasive bodies is that the horizontal abrasion movement is uncomfortable or painful for the patient and that these methods only create flat abrasion surfaces.
- the invention has for its object to provide a dental abrasive body for the treatment of a constriction of teeth with which a contact and positional stability of the teeth can be generated prophylactically.
- the tooth grinding body according to the invention is vertical between the teeth, i. H. Insertable in the longitudinal direction and designed for an abrasion movement in this direction, the one work surface being convex in cross section and the opposite work surface being concave in cross section.
- the radius of the convexly curved work surface is larger than the radius of the concavely curved work surface.
- the teeth lie side by side with convex surfaces.
- the interdental contact can thus be mapped onto a dimeric chain of joints. It is disadvantageous that such a stretched dimeric link chain is unstable, which leads to a rotation of the teeth against one another if there is too little space in the dental arch.
- a concave contact surface is formed by the convex working surface of the dental grinding body in the contact area of the one tooth. Due to the concave working surface of the dental grinding body, the radius of the convex contact surface of the adjacent contact tooth which is already present is generally adapted to the concave contact surface, the concave contact surface having a larger radius than the convex contact surface.
- the concave working surface of the dental grinding body Due to a non-abrasive design of the concave working surface of the dental grinding body, it is also possible to use it only as a guide surface, so that the convex contact surface of the tooth, as it already exists naturally, is maintained if suitable.
- the overturned dimeric dental arch chain created by the incorporation of the concave and convex contact areas in the interdental area is characterized by a very high pressure stability due to the interlocking connection of the contact areas, which increases the contact and positional stability of the adjacent teeth. This stability provides protection against recurrence after a correction of the tooth positions and prevents or reduces tertiary crowding.
- Another advantage of the treatment with the dental grinding tool according to the invention is that only a minimal removal of the approximal enamel is required on the contact surfaces of the teeth in order to achieve physical stability in each contact and thus z. B. in the anterior arch.
- the resulting space gain is 0.25 to 0.35 mm per contact area.
- the resulting artificial concave-convex abrasions transform the contacts into a stable, dimeric articulated chain.
- a vertical abrasion movement is less painful than a horizontal abrasion movement.
- Both working surfaces of the dental grinding body are preferably diamond-coated in order to enable simultaneous precise incorporation of the corresponding concave and convex contact surfaces on the teeth in the interdental area.
- both working surfaces of the dental grinding body are preferably diamond-coated in order to enable simultaneous precise incorporation of the corresponding concave and convex contact surfaces on the teeth in the interdental area.
- only the convex working surface of the dental grinding body is diamond-coated to form the concave contact surface of a tooth.
- the front edge of the dental abrasive body is not diamond-coated in order to facilitate insertion of the dental abrasive body between the teeth. For the same reason, it can be advantageous if the front edge of the tooth grinding body is pointed.
- Figure 1 a plan view of a dental grinding body
- Figure 2 the dental grinding body acc. Figure 1, in side view
- Figure 3 a plan view from above of the dental grinding body, acc. Figure 1;
- Figure 4 a cross section, acc. A-B, through the dental grinding wheel, acc. Figure 1;
- Figure 6 a side view of the dental grinding body, acc. Figure 5;
- Figure 7 a cross section, acc. line A-B of Figure 6;
- Figure 8 a stabilized row of teeth in plan view.
- 1 denotes a dental grinding body, which is provided on both sides with opposing work surfaces 2 and 3.
- the working surface 2 is concave and the working surface 3 is convex, the curvature of the working surface 3 having a radius R3 which is larger than a radius R2 of the curvature of the working surface 2.
- the work surfaces 2 and 3 are coated with an abrasive 4, which is preferably a diamond coating.
- the dental grinding body 1 is in the area of a front edge 5 pointed, which facilitates the insertion of the work surfaces 2 and 3 in the interdental spaces 10.
- the toothed grinding body 1 has a shaft 6, on the latching recess 7 of which a lifting drive 8, preferably an angular lifting drive, is shown schematically in the drawing.
- the toothed grinding body 1 can be set into an abrasion movement in its longitudinal direction by means of the lifting drive 8.
- the dental grinding body 1 is used to treat a constriction between teeth 9 vertically, i. H. introduced in the longitudinal direction.
- a linear abrasion movement is then introduced into the dental grinding body 1 in the longitudinal direction thereof via the lifting drive 8. Due to the abrasion movement, a concave contact surface 11 and a convex contact surface 12 are formed by the working surfaces 1 and 2 in the contact area of two teeth 9, which engage after the treatment has ended.
- a dental grinding body 1 is shown with reduced working surfaces 2 and 3.
- the work surfaces 2 and 3 also have smaller radii R2 and R3 than the exemplary embodiment according to FIG. 1. Only the convex work surface 3 is covered with an abrasive 4.
- the concave working surface 2 acts here only as a guide surface on the natural convex contact surface 12 of the tooth 9 coming into contact during the treatment. The natural convex curvature of this contact surface 12 is retained.
- a concave contact surface 11 with the radius R3 of the convex working surface 3 of the dental grinding body 1 is only worked into the opposite tooth in the contact area.
- the toothed grinding body 1 is driven linearly by means of a lifting drive 8 fastened to the latching recess 7 of the shaft 6.
