Have you ever been 4 minutes setting time into your PVS Impression for a crown prep on #14 only to remember that the patient has a Maryland Bridge spanning #8-X-10 that you didn’t block out? Us neither. Oh and to make matters better #8 has some gnarly external root resoprtion…Not to mention the patient isn’t exactly easy going and you’re running 10 minutes behind in clinic at the end of the day. Yea, talk about never being so fearful in your life as you *carefully* try to dislodge that impression tray from their mouth tugging with all your might. Long story short, ALWAYS double check the patinet doesn’t have a pontic, bridge, implant, etc. that needs to be blocked out with wax before taking a PVS impression.
