“SELFY ORTHODONTIC BRACKET SYSTEM”

in the name of JJ ORTHODONTICS PVT LTD an Indian nationals having address at JJ ORTHODONTICS PVT LTD, VII/202E, KANJIRAPILLY PO, CHALAKUDY, ATHIRAPPILLY RD, MUNIPARA – 680721, KERALA, INDIA.

The following specification particularly describes the invention and the manner in which it is to be performed.

FIELD OF THE INVENTION:

The present invention relates to the field of orthodontics. More particularly the present invention relates to Orthodontic Bracket System for orthodontic treatment to transfer force to move teeth from labial and lingual side.

BACKGROUND OF THE INVENTION AND PRIOR ART:

Orthodontics is the department concerned with correction of mal-aligned teeth into a proper alignment. For making these corrections, force is required which need to be transferred to those particular teeth to be moved. For that force generation wires, springs or elastics are commonly used, and brackets are used as medium to transfer that force. For achieving proper tooth movement ligation (engagement of wire in bracket) plays very important role. There are different types of ligation techniques to secure wire inside the bracket like elastomeric ligation using elastomeric rings, metallic ligation using metallic ligature wires, or self-ligation using an inherited door which engages wire inside the slot. Main drawbacks with previous ligation techniques like elastomeric ligation is force decay within 24 hours, hygiene maintenance problem. With metallic ligation laceration to the oral mucosa is there if not tucked properly and more chairside time. Especially from lingual side to do the treatment for the patients who wants invisible orthodontic treatment ligation is very difficult and it is so much time consuming. With Self ligation it is very easy for clinician with reducing chair side time, for patient ligature wire trauma can be reduced. In Self ligating brackets a gross division as Active self-ligating and Passive self-ligating is there. In Active self-ligating brackets, the door is flexible which exerts force on to the wire and in passive self-ligating brackets door is rigid which won’t exerts force on to the wire. Each design is having its own merits and demerits. Disadvantage with active self-ligating bracket is increased friction which exerts force on wire making it difficult for sliding mechanics in extraction cases. To overcome this problem interactive version of active brackets were introduced. Main disadvantage with passive self-ligating bracket was inefficiency in transferring values which were there in the bracket to the teeth.

Thus there are different self-ligating brackets were available.

Classified like Active Self-ligating and Passive Self-ligating Brackets available from various companies. In Active self-ligating brackets door is flexible which exerts force on to the wire. In Passive self-ligating Brackets door is rigid which won’t exerts force on to the wire.

With Active self-ligating brackets the doors are flexible and wont give that much comfort in opening and closing. For patient for maintenance also not that much comfortable. This flexible door creates friction which makes difficulty to slide wire in the slot.

With Passive self- ligating brackets till now available they are not transferring the values properly which were there in the brackets to the teeth because of its slot depth of .028 inch. Further lack of rotational control because of less mesiodistal dimension. Furthermore added bulk because of additional auxiliary slots. Moreover they are without inherent hooks. Further door also not that much secure because of only one pin used for the support. They were made as two-piece technique so errors in brazing process may arise. Variable torque prescription with multiple brackets makes it difficult to use clinically. Previous self-ligating brackets have one pin to support door opening and closing because of which door don’t have that much stability. In Lingual side a proper self-ligation is till date not available which provides 3 dimensional control. Thus in the evolution lot of brackets came but not fulfilled in all aspects up to the mark. Therefore there exist a need in the state of art to fabricate an Orthodontic Bracket System which is devoid of above said drawbacks.
