ABSTRACT
Background: Modified Socket shield technique, is an approach used to help maintain buccal bone level after implant insertion. However, the significance of bone grafting of the gap between the labial shield and the implant, in improving bone regeneration and prevention of the soft tissue ingrowth, has been described.
Aim of the study: Evaluation of clinical and radiographic outcomes of using xenogenic bone graft on outcome of immediate dental implant placement using the modified socket shield technique.
Material and method: 16 patients were divided into two study groups. Control group received an immediate implant with modified socket shield technique. Test group received immediate implant with modified socket shield and bone graft put in the buccal gap. Outcome measurement was primary and secondary implant stability measurement and radiographic evaluation.
Results: Peri-implant BMD after 6 months for the test group showed to increase with a % change median of 39.4 % and this was found to be significantly higher than the control group. Implant secondary stability was found to be significantly higher in the test group with a median of 78 ISQ compared to 73 ISQ for the control group.
Conclusion: DBBM is effective in healing of peri-implant defect and provides an appropriate stability and enhanced BMD. However, this technique requires proper case selection and is considered highly sensitive.
