Aim：The ultimate goal of periodontal treatment is regeneration of periodontium that have been lost due to inflammatory periodontal disease. Recently, Silicon contained Coralline Hydroxyapatite and Beta Tricalcium Phosphate bone substitute have been introduced to achieve periodontal regeneration. The purpose of this study is to evaluate the effect of the Silicon contained Coralline Hydroxyapatite and Beta Tricalcium Phosphate(BoneMedik-DM??, Meta Biomed Co., Ltd. Oksan, Korea) on periodontal intrabony defects.
Methods and materials： Clinical effects of Silicon contained Coralline Hydroxyapatite and Beta Tricalcium Phosphate implantation in intrabony defects were evaluated 6 months after surgery in Sixty-one intrabony defects from Fourty-six patients with chronic periodontitis. Twenty-nine experimental defects in twenty-five patients received the Silicon contained Coralline Hydroxyapatite and Beta Tricalcium Phosphate(test group), while Thirty-Three defects in twenty-one patients were treated with flap procedure only(control group). Comparative observation were done for preoperative and postoperative differences between control and experimental clinical parameters,-clinical attachment loss(CAL), probing depth(PD), bone probing depth(BPD), gingival recession.
Results： Postoperative improvements in CAL, PD, BPD were observed in both test and control groups(P<0.01). However, the improvements in CAL, PD, BPD of the test group were significantly greater than control group.
Conclusion： Healing of the both groups were uneventful during experimental periods. Use of Silicon contained Coralline Hydroxyapatite and Beta Tricalcium Phosphate in a flap operation resulted in significantly greater improvements in CAL, PD, and BPD over flap operation alone. Silicon contained Coralline Hydroxyapatite and Beta Tricalcium Phosphate will be good bone substitute materials for treatment of intrabony defects.
