Does using a rotary instrument to remove excess resin cement or composite ever make you nervous? Personally I find it particularly troubling around a margin of a porcelain restoration Especially when I have excess material that needs to be removed from a location not easily or safely accessed by a rotary instrument.
If youâve ever found yourself in this same predicament I would like to recommend an instrument Iâve found helpful.
A #12 surgical blade can often reach into areas, particularly interproximal areas, that a bur safely can't. As you can imagine you must be careful when using a #12 blade around soft tissue, as it is very sharp. However, as long as you pay attention, itâs a safe instrument to use.
If this sounds like something you would like to try, keep in mind that while all #12 blades are similar in shape, there are small differences, such as a #12b is sharp on both sides. The particular one of choice for me is a regular 12b from Miltex.
