After a single tooth extraction remodelling processes are initiated and morphological changes occur in the alveolar bone Immediate implant placement associated with the use of bone substitutes and connective tissue grafts seems to reduce the amount of resorption at peri implant areas Despite the advantages with the use of these techniques it is difficult to predict with precision what is going to happen after immediate implant placement since it involves hard and soft tissue volume changes.

Correlation between alveolar bone features and dimensional changes at immediate implant sites.
