DE102008057226B3 - Orthodontic device for treating defective positions of teeth and the jaw comprises soft elastic cushions arranged between the row of teeth to absorb occlusal forces during biting - Google Patents

Abstract

Orthodontic device comprises soft elastic cushions (1) arranged between the row of teeth to absorb occlusal forces during biting. A liquid is moved via communicating connections (2) to force-releasing cushions (3) which are connected to a shape-stable adjustable base (4) on one side and lie on the teeth and/or jaw sections to be treated so that a therapeutic force is exerted on biting whose direction is determined by the geometric arrangement of the base and the force-releasing cushion. Preferred Features: A gaseous medium can be used instead of the liquid. The surface of the soft elastic cushions has retentive structures on the side of the jaw to be treated.

Description

The The invention relates to an orthodontic treatment device of dental and / or Kieferfehlstellungen by occlusally generated personnel according to the preamble of claim 1.

at the well-known orthodontic Apparatuses, the active forces use, become quasi-static forces by activation of spring elements, screws, elastic plastics or elastic wires for the Tooth movement used, with too much activation, the blood circulation of periodontal tissue over a longer one Period interrupts, which leads to pain and root resorptions on the teeth can cause. The new device aims to increase the force on a physiological Limit size and accelerate the tooth movement by using intermittent Forces.

Forbital forces generated are used to correct dental and / or jaw malpositions by exposing the fluid (F) via communicating connections ( 2 ) of one or more liquid-filled force-absorbing pads ( 1 ) made of soft elastic material, which lie between the rows of teeth and absorb the forces generated occlusally, to one or more soft elastic material consisting of fluid-filled force delivery cushion ( 3 ) is moved in the starting position force and in a wide range of positive fit with one side of the orthodontic to be moved teeth (Z) and / or reshaping jaw sections (K) and with the other side on a dimensionally stable, readjustable base ( 4 ), so that during biting, an orthodontically effective pressure force is exerted on the teeth and / or jaw sections in the desired therapeutic direction (A), which results from the geometric arrangement of the base (FIG. 4 ) and the power delivery pad ( 3 ).

The device is suitable for the orthodontic treatment of tooth and / or jaw malpositions using the body's own, intermittently generated forces, the force height is physiologically limited by the fact that the patient in any pain sensations less firmly on the or the force-absorbing pad ( 1 ) bites.

Orthodontic appliances for the correction of dental and / or jaw malpositions are divided in functional orthodontic Equipment, the body's own personnel use such. As activators, and treatment devices that generate active forces by activation of elastic wires, springs, screws, elastic Plastics. Be among the group of actively exercising treatment equipment quasi-static forces for shifting teeth used. It is known that over a longer one Period intermittent forces in the orthodontically induced Tooth movement are particularly effective (see parafunction of the thumb sucking).

A device for the treatment of the temporomandibular joint with fluid-filled, lying between the rows of teeth pillow, or attached to a row of teeth cushion is in the patent US 4,211,008 A or the published patent application DE 102 39 464 A1 described. The fluid-filled cushions serve solely to distribute the force generated between the rows of teeth evenly over the corresponding portions of the rows of teeth by means of a hose connection between the cushions to treat temporomandibular joint discomfort.

Of the liquid-filled teething ring, on The children can bite at the breakthrough of the first baby teeth, the pain relief when teething and the faster break of the teeth.

task

task It is the invention for the orthodontic Tooth movement is known to be cheap dynamic forces, as they do at random and involuntary bite, especially during the empty-heartbeat, occur intermittently, for the correction of dental and / or Kieferfehlstellungen to use.

there It is crucial that forces in physiological size and force duration for the intended to be used to repair damage to the contaminated tissues, especially to avoid mucous membrane and periodontal disease. The blood circulation The loaded tissue should not be interrupted over a longer period of time be to tissue damage to prevent.

The Apparatus should over a long treatment period can be useable to cost by multiple Reduce new production.

These Tasks are solved by the features of claim 1. Advantageous embodiments emerge from the features of claims 2 to 15.

embodiment

One embodiment The invention is illustrated in the drawings and will be described in more detail below.

It demonstrate

1 a perspective view of the orthodontic appliance with dashed lines force receiving pads, connecting channels, power delivery pads and adjusting screw,

2 a partial perspective view, cut in the transverse plane at the level of the lower right first molar,

3 the pressure curve in the area of the fluid-filled pillows in arbitrary biting a and in the empty-cycle b.

When biting on the or between the chewing surfaces lying force bearing pad ( 1 ) exerted a force, whereby it leads to an increase in pressure in the force-absorbing pad filled with a non-toxic liquid (F) ( 1 ) and the power delivery pad ( 3 ), because both cushions communicate via communicating connection channels ( 2 ) are connected.

On the Kraftabgabekissen first force and in many areas positively fitting teeth (Z) and jaw sections (K) is given in the therapeutic direction transversely widening force acting in the direction (A) because the opposing force of the dimensionally stable base ( 4 ), which extends to the contralateral side.

The transversally expanding force in the exemplary embodiment leads in the long term to a change in the position of teeth and / or jaw sections due to conversion processes in the tissues involved, so that after a certain treatment time the force delivery pads ( 3 ) with unloaded force-absorbing pads ( 1 ) no longer or no longer fit positively in all areas of the row of teeth or jaw sections.

In order to be able to use the orthodontic appliance over a long period, the basis ( 4 ) in the exemplary embodiment in the therapeutic direction via an adjusting screw ( 5 ) adapt to the new anatomical situation in such a way that again a substantial positive connection between power delivery ( 3 ) and teeth (Z) and / or Kierferabschnitten (K) is achieved as at the beginning of treatment.
