      Lost a client over this once. Endo doc broke a new crown that the GP seated on a hot tooth. Wanted me to remake the crown for free, I said to send the bill to the Endodontist. Last case I got from that p.i.t.a.

      Understood. Whoever chooses to crown a "hot tooth" should bear the cost of replacing the crown if needed. If an informed patient says to do it anyway, they should bear the cost. If the GP chooses to do it, they should. My new warranty on the back of my Rx is probably going to cost me work, but I'm tired of bearing the cost of poor planning, poor impressions, poor shade taking, unrealistic patient expectations, etc. Most of my doc's are wonderful, but these problems do crop up.

      Any lab that is redoing a restoration that has had endo access for free is just bad business.

      I might do it as a favor for a good client but there is no warranty on that.

      Ironically , I made myself a LU crown a few years ago. Little did I know but I required an endo a year later.

      A restoration that has had endo access a loses its strength by 30 % according to the prosthetic literature, therefore a new crown is a must with the new build up, a new lab fee.

      That might be true of e.max and maybe even zirconia, but it sure as hell isnt true of gold crowns and probably not of PFM's as long as the porcelain doesn't fracture in the process of cutting the accesss hole. To make a blanket statement about all restorations is BS.

      I recently was asked to design a bicuspid PFZ with an access hole designed in it at the patients request. This guy had already been around the block with this issue. 3 months later he needed endo. It worked out great.

      If they are bonded there is no way to use an old file to make a 2nd replacement crown from an old file. The e.max needs to be prepped off and the preparation will be very different than the original. We have had docs asking about this for years.

      Well the prosthetic literature is a positive and reliable way to know what works and what does not, and most of the time the Endo guys make the access hole to big weakening the tooth if it is crowned , so a new restoration is a most especially in cases of bridges with multiple abutments. Therefore as the saying goes ¨you break it you pay it¨.
