message board of surface contact you can get here while using and curing, the broader your contact will be. You will be left with a small void where your instrument was, but the frame of cured composite will hold your contact so you can just restore the remainder of the filling. If you have small or intricate voids that can be hard to fill with composite, you can use a bit of flowable and follow up with paste composite to push it out, à la Bioclear injection molding technique. You will get a good floss snap every time. This is an easier technique with larger preparations but can be completed with moderate-sized ones as well. I hope this helps! n 17/2/2018 the67project Member Since: 25/10/17 Post: 23 of 61 I pull out a 12 blade and use that to remove excess flash quickly and precisely, rather than trying to use a flame bur. It also gives you precise control to round corners. I love it on the anteriors and even interproximal on premolars. n 17/2/2018 TuttleNumbNow Member Since: 02/11/15 Post: 24 of 61 Think of filling a multisurface prep as filling three one-surface preps. Instead of bulk-filling, then having to recover from a mess of bulk to reduce, voids with tough access and hard-to-contour line angles and insufficient contacts, manipulate the matrix if needed between increments. Seems like it would take too much time, but it saves time due to less redos and hassles. n 17/2/2018 mooredge Member Since: 22/04/08 Post: 27 of 61 owensdent Member Since: 27/06/02 Post: 28 of 61 OptraGate and Greater Curve band. n 17/2/2018 #12 blade works well. Below is a Class IV case: Prep Greater Curve set up. Contact window made. Distal contour burnished in. Now just a matter of placing composite against a solid surface. Composite layered and ready for contouring. Refinements accomplished with #12 blade. 32 JUNE 2018 // dentaltownuk.comhttp://www.dentaltown.com http://www.dentaltownuk.com
