This 1-year prospective study evaluated horizontal and vertical facial gingival tissue changes following immediate implant placement and provisionalization (IIPP) with and without bone graft in the implant-socket gap (ISG). During IIPP, 10 patients received bone graft material in the ISG (G group), while the other 10 patients did not (NG group). The implants were evaluated for implant stability quotient (ISQ), modified plaque index (mPI), modified bleeding index (mBI), marginal bone level (MBL), facial gingival level (FGL) and facial gingival profile (FGP) changes. The mean ISQ value at 9-month follow upwas statistically significantly greater than on the day of implant surgery ( p <.05). The mPI and mBI scores demonstrated that patients were able to maintain a good level of hygiene. There were no statistically significant differences in the mean MBL changes between the G and NG groups ( p >.05). There were statistically significant differences in FGL changes between the G (-0.77 mm) and NG (-1.35 mm) groups ( p =.035). There were no statistically significant differences in FGP changes between the G and NG groups (p>.05). However, statistically significant differences were noted in FGP change between the 3-12 and 0-12 month intervals in both groups (p<.05). Within the limitations of this study, although no significant differences were noted in FGP changes between groups, G group experienced significantly less FGL changes than NG group. Bone graft material placement into ISG seems to be advantageous for tissue preservation during IIPP. However, future long-term studies, with larger sample size, are needed to validate the efficacy of such procedure.
