  Abstract 

Torque is the force which gives the operator control over the movements of roots of teeth in bilateral direction. There are various pliers available to apply torque in individual tooth, but none of the pliers are capable of measuring accurately the degrees of torque incorporated, so we have attempted to make a modified torquing plier to incorporate and measure the degrees of incorporated torque precisely.

  Introduction Top


Torque is the force that enables the orthodontist to control the axial inclinations of teeth in labial and lingual direction and to place them in the harmonizing positions that are desirable for finished case. When an orthodontist does not have an understanding of torque or is unable to provide the accurate torque, many adverse tooth movements will result in relapse and thus making orthodontic treatment more difficult.[1] The treatment outcome may became undesirable and less stable. To incorporate accurate torque to enhance proper root positioning, thereby increasing the stability of result, a new concept of modifying the plier was thought off. This paper presents a plier to incorporate and measure the degrees of torque accurately for aligning individual tooth roots.


  Methodology Top


A protractor was attached to the plier with accuracy and clearly visible markings [Figure 1]. To incorporate the torque, the wire was held as shown in [Figure 2]. The wire was held at the slot [Figure 3] on the beak of the plier on inner edge, which corresponds to the zero degree marking for more accurate and precise measurement. The archwire was engaged, and with the corresponding metallic key of corresponding slot dimension, the necessary torque was delivered in the archwire by moving the key across the protractor [Figure 4] and [Figure 5]. Thus, the plier enabled us not only to incorporate but also measure the incorporated torque. The current method enables us to incorporate torque with more precision.

  Discussion Top


A common problem in orthodontics is the repositioning of a root having crown which is generally properly located, but where the root of the tooth is angled labially or lingually out of the ideal dental arch position. Correction of these problems is important not only for cosmetic reasons but also, more importantly, to ensure proper occlusion and chewing function of the teeth.[2]

With the advent of preadjusted edgewise technique, the incorporation of the third order bends has become obsolete, but in cases of transposed canine or palatally placed canine, there is a requirement to place a precise degree of torque to place the canine root in the cancellous bone, these guidelines are also true in cases of palatally placed upper lateral incisor or any other condition. It is particularly difficult to measure the labial/lingual root torque that is incorporated in the wire.[2] This, thus, demands a plier assembly which is not only able to incorporate the required degrees of torque but also has a provision to measure it. This invention enables the rapid and accurate formation of twisted portions of an archwire to be used in applying torque to one or more teeth.

Advantages of modified plier

  • Measure the torque at the same time of incorporation
  • Highly accurate
  • Extra grid not required to measure the torque
  • Clearly visible metal engraving markings on protractor for easy visibility
  • Save clinical chair-side time.


Disadvantages

  • Increased bulk of the plier.


Although bulky, this drawback is acceptable at the cost of torque accuracy delivered and less time consumed, “after all precision is all that matters.”


  Conclusion Top


The innovative torquing plier with key is highly accurate, reliable, and consumes less time to not only incorporate but also measure the degrees of incorporated torque in the wire. It promises an armamentarium that would be self-sufficient and provide all the necessary functions and enable an orthodontist to deliver a quality care to the patient.
