Abstract
Purpose: This study evaluated the clinical applications of implant placement and guided bone regeneration using a mineralized bone allograft and a barrier membrane derived from ox pericardium.
Methods: From January 2007 to June 2009, among the patients who received an implant at Chosun University Dental Hospital, patients were selected if they were treated with guided bone regeneration (GBR) with simultaneous implant placement or GBR prior to implant placement. The selected patients were sorted according to the materials and membranes used in GBR, and the implant survival rate was recorded by clinical examination and reviewing the medical records and the radiographs. Each study list was analyzed by SPSS (version 12.0, SPSS Inc., USA) software and the survival rate was verified by Chi-square tests. P values less than 0.05% were deemed significant.
Results: 278 implants were placed on a total of 101 patients and 8 implants resulted in failure. Three implants failed among 15 implants with only a mineralized bone allograft. No failure was shown among the 74 implants placed with mineralized bone allograft and a barrier membrane derived from ox pericardium. One group of 4 implant placements showed failure among the 102 implants placed with a mineralized bone allograft and another bone graft material. The group that had a barrier membrane derived from ox pericardium with a mineralized bone allograft or other bone materials showed no implant failure. Three failures were shown among the 21 implants placed with only bone graft and not using a membrane. The group with membranes other than a barrier membrane derived from ox pericardium showed 5 failures among 170 implants.
Conclusion: The implant survival rate of the group with GBR using a mineralized bone allograft was 96.3%, which meant there was little difference compared to the groups of another bone graft materials (98.9%). The implant survival rate of the group without a membrane-was 85.7% and it showed a significant difference compared to the group using a barrier membrane derived from ox pericardium (100%) and the group using another membrane (97.1%).
