Once the temperature is raised, this alloy becomes stiff and regains its original shape Shape memory. This phenomenon is due to the reverting of the alloy to its original austenitic phase. The temperature at which there is change from one phase to the other is know as the transition temperature.
A locking indentation in the sheath fastens the appliance through stainless steel tab to the maxillary molar band. An E-chainlsteel ligature can also be additionally utilized for preventing accidental dislodging.
This appliance comes in sizes ranging from 26 mm to 44 mm in 2 mm increments. The appliance is packed in sterile packets separately. There is inbuilt pre-programmed force application of g in 3 mm increments and is therefore self limiting. However slight adjustments can still be made by the operator to either constrict or add further expansion into the appliance. The transition temperature of NPE is at 94Op. Department of Dental Surgery. Armed Forces Medical College. Pune Ice cold spray containing tetraflouroethane is utilized onto the NPE to further dead soften the appliance just prior to placement inside mouth.
This ensures ease in seating of the bands by the operator. One might require another NPE if more than 8 mms of expansion is needed. The difference between the two measurements is the amount of expansion required. Measure the distance between right and left maxillary first molars from the lingual surfaces where the sheaths will be placed. Add this value to the required expansion.
The total will indicate the size of the NPE to use allowing for the prescribed expansion plus 1.
This will facilitate fit and placement of the bands with lingual sheaths on these teeth. The bands are removed. The bands and the NPE are now assembled outside the mouth as a single passive unit. To be extra careful- a trial fit can be done. Any adjustment required can then be done with the help of special 3-jaw NPE plier.
A good quality glass ionomer cement normalllight cure is used. It is mixed and applied onto the bands which are supported by a piece of the wax on the occlusal side to prevent flow of the cement. Ingervall B, Thilander B.
