目的:评价引导骨再生(GBR)技术联合高压氧(HBO)治疗重建种植体周围炎所导致周围骨缺损的临床效果。方法:经过X线和临床检查确诊的7颗种植体因为种植体周围炎导致牙槽骨明显吸收但种植体稳固病例,拆除上部结构重新安装覆盖螺丝,通过牙周手术清除炎性组织,同期在骨缺损处充填骨移植材料,覆盖生物膜,术后配合HBO治疗1周,常规抗炎治疗及口腔护理。6个月后评估骨缺损的再生情况,考虑二期手术及后期冠修复,定期随访1年,评估骨再生的稳定情况。结果:7颗种植体周围骨再生的高度和宽度术后6个月都得到了明显恢复,而且术后1年仍维持稳定。结论:临床上采用GBR联合HBO治疗用于重建种植体周围炎所导致的种植体周围骨缺损的效果理想。
Objective:To evaluate the clinical effect of guided bone regeneration (GBR) technique and Hyperbaric Oxygen (HBO) treatment for remodeling the bone defects induced by peri-implantitis. Method:After the X-ray and clini-cally diagnosed,there 7 solid implants have significant absorption of alveolar bone around the implants by peri-implantitis , complete demolition of the upper structure reinstall cover screws,remove inflamed tissue all through periodontal surgery,and the same period in the site of bone defect was filled with bone graft material and subsequently covered with biofilm ,after all patients receive conventional antibiotic treatment and oral care. The bone regeneration surrounding the implant was assessed 6 months later,a phaseⅡprocedu and porcelain crowns repair were performed,regular follow-up a year to assess the stabili-ty of regenerated bone. Result:After 6 months,the height and width of regenerated bone around the 7 peri-implants have significantly recovered,and remained stable after one year. Conclusion:The clinical effect of GBR and HBO for remodeling the bone defects induced by peri-implantitis is ideal.
