Implant Supported Upper Dentures Not Passive: What Can I Do?

Obviously this case has some fatal flaws. CT planning is not mandatory but very useful. The vast majority of oral surgeons are not trained in prosthetics and therfore are not going to comprhensively plan an implant case. Its like building a house, the contractor needs to have developed a comprhensive plan otherwise the sink (although very well plumbed) may end up in the hall. You have a serious problem when you start loosing implants and you need to see a credentialed dental implantologist to get this case corrected. My advice is to Visit ADIA.com, ICOI.com or AAID.com to find a dental implantologist who is experienced and knowladgable in implant surgery as well as prosthetics.Michael E. Corsello DMD

You say that the bar retained dentures are not passive, but there is the possibility that the bar itself is not passive. This is a common reason why screws loosen with bar cases. If the bar or bars are passive, then there could be some problem with the way the attachments are held in the denture that causes it not to fit passively. Replacing the offending attachment should correct the problem. If you have had an implant break, I would be concerned about whether the denture or bar were designed with the propper engineering principles such as long cantilevers because these forces are usually greater. Talk to your dentist about these concerns and try to determine the reason why these things are happening. Only then will you be able to do something to correct them. Good luck! Dr. Carlos Boudet
