Can dentist bill me for bad crown on my implant which was not delivered into my mouth, if insurance will not cover?

Crown did not fit properly, dentist did a lot of grinding, after crown did not look natural (shapeless, shapeless). I asked her to send it back to lab. She argued. I told I am going to another dentist, they were angry. They unhappily told that they can correct it and if I am going to another dentist they are going to charge me directly $1300 for their job (time in office and improper crown). Insurance will not pay if the crown is not delivered into my mouth. Can they charge me directly?
