Robert,

Any chance you could have the dental office email you a post op xray of the bridge and post it here???

Unless you have a compromised dentition meaning you are missing other teeth and that has affected your bite or you have periodontal disease or some other issue to warrant a three unit bridge.... it is not always ideal to bridge all three implants together as cleaning them can be a bit tedious. So I'm wondering why the dentist chose to do it this way.

The abutment is suppose to be screwed into the implant or perhaps in some systems cemented into the implant. The crown portion is cemented over the abutment. Nothing is suppose to be just resting on the implant. Yes, the proper size screws need to be used and they usually have to be torqued a certain amount for stability. Do you know if he did any of those things??

Here is a cute little animation and explanation of an impalnt...
