[QUOTE="sizzur82, post: 176341, member: 10362"] Hello all, i have been lurking around for a while and find the information on this forum quite informative. Thank you all for contributing and letting folks like me learn! I want to ask how you all go about fitting your acrylic partial dentures back onto the model. In the past, I just went straight to insertion and found it very cumbersome to trim and adjust using the patients mouth. I have since started duplicating my models. My alginate states that i can double pour my impressions with little distortion and have been doing so thus far. For the most part its okay, but I know there is a slight distortion or less detail captured when pouring out twice with the same impression. It is difficult to make it still due to path of insertion issues or undercuts. I'm using an articulating ribbon to mark any pre-mature contacts. Another question i would like to ask is how you all flask acrylic partials? All stone/plaster or do you use lab putty around the abutments? I use all stone/plaster but i find a lot of the time they break off during boil out, especially when the abutment tooth that is clasped is surrounded with adjacent denture teeth, and it's always worrisome putting it back together. Clearly, I am not very experienced yet, but would love to learn new and more efficient techniques. [/QUOTE]
