I had surgery for 4 connected missing teeth. They put in 3 implants and the teeth are to be replaced by a single unit of 3 implant abutments and a bridge for the 4th tooth. When the unit came back from the lab it did not fit (go more than half way down) on the implant posts. Even after an hour of drilling it still didn't fit. So the dentist made another mold and over a couple of days modified the abutment unit to fit. I have no idea how much drilling or what he did to make it fit. I am suspicious that all the extra drilling has damaged the integrity of the mold and the dentist is trying to save $$ by not ordering a new unit (3 abutments + bridge) made. Are my fears justified? If so can I demand that he order a new mold?
