in a good seal and keeps the dam from being bunched up on the lingual and prevents the dam from sliding the wedge back out. Then I prep away and don't worry if I chew up the wedge as it protects the rubber dam. ■ 4/1/2017 The clamp needs to sit with all four tines giving decent pressure on the tooth. If the clamp is not doing this, chances are the clamp will pop off or rotate with a mesial inclination of the bow. Sometimes this mesial incline or the Curve of Spee will not allow you to re-engage the RD clamp holes, so you can get the clamp off or reposition it with your RD forceps. If this happens you can use your XR ring forcep in a reverse position and engage the bow. Apply outward pressure to the bow to release the clamp tines. At this point inspect your clamp for fatigue and use the 110s to tighten them again or toss and get a new clamp. I use the third largest punch hole for the molars, the next smaller for premolars and the next smaller for anteriors. I never use the largest or smallest punches. ■ Tyler11 Member Since: 05/24/04 Post: 41 of 98 4/2/2017 Join the discussion online at Dentaltown Search: "Dam Frustrations" Do you have any dam troubles?
