说明书全文 | The present patent application for utility model concerns the constructive disposition applied to self-ligating brackets for orthodontic treatment, which comprises a housing for a sliding lock, which prevents the slipping of the orthodontic wire, mainly the slipping of the said bracket lock at the time of unlocking, serving as an opening limiter, whose sliding movement of the bracket can or cannot be assisted by a key, which enables the displacement of the lid to the opening position. As well known, the self-ligating orthodontic brackets do not need tying the steel wire to the bracket, as these brackets are built with a sliding lock system, which prevents the slip out of steel wire housed in the slot. However, the constructive disposition of the self-ligating orthodontic brackets enhance s the accumulation of food, and consequently the proliferation of bacteria. Another inconvenience of the self-ligating brackets is their non-ergonomic shape, which frequently hurts the buccal mucosa, causing small wounds in the patient's mouth. The lock mechanism of self-ligating orthodontic brackets presents another inconvenience, considering that its locking system requires a specific key by the orthodontist to open the lock. In this respect, the following patent documents can be mentioned: The claimed invention is intended to solve such problems, in addition to providing better esthetics in using devices for orthodontic treatment. The main advantage of constructive disposition of the orthodontic brackets is in the closed housing for the lock, which reduced the accumulation of food, and consequently the proliferation of bacteria, as well as in the fixing system of the said lock on the bracket, which is provided with a groove, which enables its movement by means of fixation of a rotating key, or by means of a straight line movement with no need of a specific key. The object of the patent application is a constructive disposition for a self-ligatingbracket, provided with a closed housing for a sliding lock, which reduced the accumulation of food, and consequently, the proliferation of bacteria, mainly the exit of the said lock from the bracket at the time of unlocking, whose lock fixation system on the bracket is presented by means of a straight groove, which does not require the use of a specific key for the opening of the said lock, or, an arc-shaped groove, which enables the lock movement turning the key to open the lock.
The constructive disposition comprises a closed housing (2) in the bracket body (1) for a sliding lock (3), which reduces the possibility of accumulation of food, and consequently, the proliferation of bacteria, mainly the exit of the said lock from the bracket at the time of unlocking, performing the function of the lock forward movement limiter when unlocking, preventing it from slipping totally from the bracket body. The lock fixation (3) on the bracket (1) is provided by means of a straight groove (4) located on the bracket body (1), which does not require the use of a specific key for the opening of the said lock (3), or, an arc-shaped groove (5), which enables the movement of the said lock (3) by turning a specific key (6), providing the opening. The lock (3) is also provided with side cams (7), which fit in the groove walls (8) for the steel wire, assisting the said lock (3) locking on the bracket body (1). This locking is also assisted by a slight inclination (10) existing on the lock sides (3), as well as a groove (9) on the face of the said lock. By means of As an example of the lock opening and closing by means of a specific key, The exposition of the present invention is only illustrative and changes might be done in the details, especially to what refers to size, shape, dimension, production, industrial and visual disposition, but always within the principle of creation, to the extent indicated by the knowledge of the claim presented with this patent application. |
