Immediate Implant placement into fresh extraction mandibular molars sockets with or without bone grafting. Clinical cases report.

Abstract

Objectives:  The aim of this series of cases was to evaluate the differences and reactions of tissues around immediate implants placed in infected or noninfected sockets in mandibular molars, with or without bone graft placement. Methods: Four immediate implants were placed in infected or non-infected mandibular molar sockets in four patients. The patients were divided into 2 groups (n=2). In Group 1 a bone graft was placed and in Group 2 no bone graft was placed. Clinical and radiographic evaluations were performed 8 days and 4 months after implant placement in all patients. Results: At 4 months follow-up, both groups showed favorable bone-implant integration, and the survival rate of both groups was 100%. No greater difference was observed between the 2 groups to the radiographic evaluation at 8 days and 4 months related to changes in the level of the bone crest in the vertical and horizontal direction. No major differences were found in bone and soft tissue regeneration between cases where bone graft was placed, and in the cases where bone grafting was not used.

Conclusions: Within the limitations of this study, we can conclude that immediate implant placement in infected or noninfected sockets in mandibular molars, with bone graft or without grafting does not present differences.
