Expect nothing else than doing your best to provide a good treatment plan presentation. Do not expect acceptance. Do not expect the return. Focus on the process. The goal is just a result.
It means that initially you need to present ten comprehensive full mouth treatment plans to have only one patient to accept it. Regular dentists give up in the process and feel it is useless to present these kind of cases and they just keep doing basic dentistry. Successful dentists keep presenting them, unattached to the acceptance outcome and, eventually, the practice becomes the local reference for comprehensive treatments.
