  • Advice to Prevent Zirconia Bridge Warpage?

    Anyone have any advice on zirconia bridge frameworks "warping"? Hardly ever happens with frameworks with no curve, but seems to be more frequent with 4 unit and larger frames that curve (anterior). Individual units fit terrific internally and marginally, but 2-3 out of 10 times the frames will rock slightly....

    The most common cause of that for me would be weak or improperly positioned connectors. The zirconia likes to be uniform and shrink as a whole. Thin areas tend to shrink faster (for obvious reasons). Connectors that are too far lingual or facial also seem to "bend" the frame slightly due to the thicker, less evenly distributed portions on either side.
