I am shocked to read this. It is however possible that the doctor in question attempted to place an immediate implant for you (at the same time as the extraction) but for some reason decided not to do it and place it at a later time. In any case you were suppose to be informed of this.
I am very keen to see the notes the dentist wrote for you before saying anything else.
PS: I have never heard of sensors in the chair handles/and the fact that you were told not to get a x ray done for a week sounds ridiculous.
