Purpose:
This study compares success rates and hard and periimplant soft tissue responses, between placement and nonplacement of the following five different types of grafts: autogenous bone (A); deproteinized bovine bone mineral (H); demineralized freeze-dried bone allograft (D); A + H; A + D in horizontal gaps between implant surfaces and the buccal bone wall, in immediate placed and immediate nonfunctional loaded implants in maxillary arch.
Material And Methods:
Forty-one patients with a mean age of 42.5 years were enrolled in this retrospective comparative study. Outcome assessments included clinical and radiographic evaluation.
Results:
Patients were followed up on average for 32 months with a 100% implant survival rate. No significant difference was found between the two groups.
Conclusion:
Results of this study suggest that immediate placed and immediate restored single implants are valuable therapeutic options in the maxillary arch. The types of grafts placement: A, H, D, A + H, and A + D in horizontal gaps have no additional benefit in promoting better clinical outcomes given that a thick gingival biotype is present.
