Yes, there is a big contrast between dental filling and dental implant. Dental fillings are majorly done to fill up a cavity caused by decay. The entire tooth is not removed in a dental filling. The decayed area is merely scrapped off and filled with another material. Dental implants on the other hand are the replacement of lost teeth as they are fixed into the jaw bone, to function like a natural tooth. The procedures are quite different, so are the precautions after these procedures.
