shoring
several methods can be used to shore up a trench. hydraulic shoring is the use of hydraulic pistons that can be pumped outward until they press up against the trench walls. they are typically combined with steel plate or a special heavy plywood called finform. another method is called beam and plate, in which steel i-beams are driven into the ground and steel plates are slid in amongst them. a similar method that uses wood planks is called soldier boarding. hydraulics tend to be faster and easier; the other methods tend to be used for longer term applications or larger excavations.

bullet::::- "traditional metal wired braces" are stainless-steel and are sometimes used in combination with titanium. traditional metal braces are the most common type of braces. these braces have a metal bracket with elastic (rubber band) ties holding the wire onto the metal brackets. the second-most common type of braces are self-ligating braces that do not require elastic ties. instead, the wire goes through the bracket. often with this type of braces, treatment time is reduced, there is less pain on the teeth, and fewer adjustments are required than with traditional braces.
