Conclusion It can be concluded that bone remodeling occurs after tooth extraction and immediate implant installation
Purpose The objective of this systematic review was to assess the three-dimensional changes in bone tissue after immediate installation of a single implant in a fresh extraction socket in the anterior maxilla .
Esthetic outcomes of immediate implant placements.
BACKGROUND Single-rooted teeth deemed not restorable via conventional means may be c and i date s for implant placement at the time of tooth extraction .  Immediate implant placements are believed to preserve soft and hard tissue form and contours , reduce the need for augmentation procedures , minimize surgical exposure of the patient , reduce treatment time and improve esthetic outcomes . METHOD This retrospective review analyzed the  esthetic outcomes of 42 non-adjacent single-unit implant restorations completed using an immediate implant surgical placement protocol .  RESULTS The mean time in function was 18.9 months ( range 6 - 50 months ) and the majority of implants placed had a restorative platform diameter of 4.1 and 4.8 mm . A highly significant change in crown height due to marginal tissue recession of 0.9 + /- 0.78 mm ( P=0.000 ) was recorded for all sites , with no difference seen between implant systems ( P=0.837 ) . Thin tissue biotype showed slightly greater recession than thick tissue biotype ( 1 + /- 0.9 vs. 0.7 + /- 0.57 mm , respectively ) ; however , this difference was not statistically significant ( P=0.187 ) . Implants with a buccal shoulder position showed three times more recession than implants with a lingual shoulder position ( 1.8 + /- 0.83 vs. 0.6 + /- 0.55 mm , respectively ) with the difference being highly statistically significant ( P=0.000 ) . CONCLUSIONS Immediate implant placement requires very careful case selection and high surgical skill levels if esthetic outcomes are to be achieved . Long-term prospect i ve studies on tissue stability and esthetic outcomes are needed
