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 .
Facial gingival tissue stability following immediate placement and provisionalization of maxillary anterior single implants: a 2- to 8-year follow-up.
PURPOSE This is a follow-up of an earlier 1-year prospect i ve study on implant success rates and the peri-implant response after immediate placement and provisionalization of single implants in the esthetic zone . The effects of gingival biotype on the peri-implant tissues were also evaluated . MATERIAL S AND METHODS Thirty-five patients were evaluated clinical ly and radiographically at presurgical examination ( T0 ) , immediately after  immediate implant placement and provisionalization  ( T1 ) , 1 year after implant surgery  ( T2 ) , and the latest follow-up appointment ( T3 ) . Data were analyzed using t tests and repeated- measures analysis of variance at the significance level of alpha = .05 . RESULTS After a mean follow-up time of 4 years ( range , 2 to 8.2 years ) , all implants remained in function . At T3 , the mean mesial and distal marginal bone level changes were significantly greater than those observed at T2 . At T3 , the mean mesial and distal papilla level changes were significantly smaller than those observed at T2 , whereas the mean facial gingival level change was significantly greater than that observed at T2 . Sites with a thick gingival biotype exhibited significantly smaller changes in facial gingival levels than sites with a thin gingival biotype at both T2 and T3 . CONCLUSIONS Favorable implant success rates and peri-implant tissue responses can be achieved with this procedure . While the results suggest the possibility of spontaneous papilla regeneration over time following this procedure , continuing recession of the facial gingival tissue was also observed . The effect of gingival biotype on peri-implant tissue response seemed to be limited only to facial gingival recession and did not influence interproximal papilla or proximal marginal bone levels
