A

type IV

19
Q

When is immediate implant placement indicated?

A
  • adequate presence of the buccal plate
  • soft tissue may/may not be intact
  • adequate alveolar bone in the palatal aspect of extraction socket for primary stability of the implant
  • esthetic considerations
  • reduced treatment time
