Immediate implant placement and delay implement placements

[Freefrompain]

My lower right first molar needed to be extracted due to the fracture.
I am thinking to replace it with the implant after extraction.
The surrounded bone of the tooth has melted due to the infection.
I had visited few dentists.
One of them suggested to extract it, replace it with temporary tooth and wait 3 months to allow healing then do the implant placement.

Another dentist suggested to do the immediate implant placement after the extraction and if it doesn't hold then leave it 3-4 months to heal with bone grafting.

Is it possible to do the immediate implant placement (with bone grafting) after extraction with my tooth since the surrounded bone has melted?

Extract, allow healing for 3 months, assess for grafting. If necessary then graft, wait further 3 months and reassess.
Immediate implant into a fresh extraction wound rarely has the right bone contours.
