  Abstract 


The main objective of this innovation was to ease, minimise the working time at chair side by loading the crimpable hook for retraction/protraction/any other clinical situation demanding placement of the crimpable hook when the archwire is in position. For the same reason a plier routinely used which can be modified to suit the above purpose was thought off. This innovative plier serves dual purpose. As it is a modified distal end cutter, there is an added feature of crimping the hook to the arch wire apart from serving the basic purpose of cutting the distal end. Thus saves time at chairside. The innovative FAS *twin function plier has a high efficiency, ease of use, is economic, for distal end cutting of the arch wire.

Keywords: Crimpable hook and stainless steel arch wire, FAS twin function plier (crimpable hook plier, distal end cutter)

  Introduction Top


Clinicians often find it difficult and time-consuming to make hooks in the stainless steel archwire for enmass retraction of anterior teeth in clinical scenario.

Crimpable hooks present itself to this challenge by getting attached to the archwire with the help of a crimpable hook plier that can be used intraorally or with the help of other pliers used extraorally.

Removing the archwire from the bracket slot intraorally and placing marks to precisely locate the crimpable hooks are often time-consuming though not very tedious.

This bond is not very satisfactory and also leaves an indentation on the wire thus distorting it to some extent. Moreover, an extra plier is needed in the armamentarium at an added cost.

Thus, the aim of this innovation was to design a plier that combines the function of these crimping hooks on to the archwire and also serve other functions such as cutting distal ends of archwire intraorally.


  Materials Used Top


The various materials used in the study were:

  • Distal end cutter
  • 0.019″ × 0.025″ stainless steel archwire
  • Crimpable hooks
  • Carborundum discs.


The currently used distal end cutter was modified, and a slot was made in the contra-angled beak of the plier as shown in [Figure1]a and [Figure 1]b.

The slot made in the plier was used to carry the hook intraorally to the archwire, and the part of beaks above and below the slot was used to apply a firm pressure to crimp the hook onto the arch wire [Figure1]c. The blades of the distal end cutter were not tampered during the fabrication of the modification and hence, the functionality of the plier remained unaltered.

The slot was made in the head of the plier to hold the crimpable hook and carry it to the oral cavity as demonstrated in [Figure1]d. The hook was crimped onto the wire without any difficulty and they remained stable.


  Results Top


The net result was the addition of an extra function to the already existing distal end cutter, i.e.,the function of crimping hook onto the archwire giving birth to a new plier called the FAS twin function plier(named after the authors, Dr. Fakkirsab, Dr. Anup, Dr. Shivaprakash).

This plier has the dual function of crimping hooks efficiently onto the steel archwire as well as cutting distal ends of wire, during the course of active orthodontic treatment when the wire is in position.


  Discussion Top


The distal end cutter is an integral part of armamentarium for every orthodontist. It is used for cutting the distal ends of wire that projects out from the molar tube during orthodontic treatment process. These wires may hurt the buccal mucosa and hence must be cut. Distal end cutter has a contra-angled head enabling it to reach distal to the second molar with relative ease as compared with other pliers and cutters.

Incorporating the functions of the crimpable hook plier in the distal end cutter was done. In this process, the efficiency and effectiveness of the distal end cutter were not compromised as the cutting blades of the plier remain unaltered and only the part of the head above the blades was used. The pliers safety mechanism of holding the cut end of wire also remained untampered.

The design of conventional crimpable hook plier is such that it just crimps the hook base to archwire at a single point. The FAS twin function plier is superior in this aspect as it crimps the mesial and distal ends of the hook base firmly on to the wire thus providing better stability and more promising results.

This innovation serves dual purpose of distal end cutter with crimping of hook. Thus, the objective of this innovation was served. It minimizes to working time at chairside by loading the crimpable hook for retraction / protraction / any other clinical situation demanding placement of the crimpable hook when the archwire is in position.

The distinct advantages of this plier are:

  • Dual purpose served at no compromise in any functioning
  • No additional cost
  • Decreased chairside time of making hooks in the archwire
  • No need of any additional plier for crimping hooks
  • Distal end cutter being a necessary plier in the kit is invariably used by all orthodontists, so the new innovative plier replaces the old distal end cutter and crimpable hook plier as it provides functions of both.


The only factor that has to be considered is that the beak of the plier must be of tungsten carbide to withstand the pressure that is generated in the beaks of the plier during the crimping of the hook.


  Conclusion Top


Thus, the FAS twin function plier might be a viable and efficient substitute to the currently used pliers as it provides the functions of both pliers efficiently and effectively with a resultant decrease in chairside time and is cost-effective. *Patent pending.
