An Innovative Light Curing Unit With Multiple Portable Power Sources

Abstract

The process of attaching brackets to the tooth surface has evolved from brackets being welded to bands to attaching them using light cure composite resin materials. Similarly, the curing lights have advanced from bulky Quartz-Tungsten-Halogen lights to light-emitting diode (LED) curing units. The LED curing units available now have advanced features like high intensity light, reduced curing time, and are very expensive and rely upon prior charging of the unit. The present article describes a curing light which is powered by an external power source like, laptop, smartphone, and power bank and is very compact compared to the present curing lights and is also less expensive.

The effect of different orthodontic mini-implant brands and geometry on primary stability (an in vitro study)

“…60° was the drilling angle, according to previous studies assuming the highest primary stability was measured when the insertion angle was between 60° and 70° [ 16 , 17 ]. The primary stability was measured by measuring the pullout force (POF) of each mini-implant while they are withdrawn by Universal Testing Machine device [ 18 , 19 ]. These results show that the primary stability in each brand increases while their sizes are increasing, having the highest (POF) in the largest size (diameter and length), which is (1.8 × 10) for GNI and OSTEONIC, and (1.5 × 10) for MORELLI.…”
