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 effects of guided bone regeneration (GBR) combined with hyperbaric oxygen (HBO) in the treatment of peri-implantitis caused by peri-implantitis. Methods: Seven implants diagnosed by X-ray and clinical examinations showed obvious alveolar bone absorption due to peri-implantitis, but the implants were stable. The superstructure was disassembled and the screws were removed. The inflammatory tissues were removed by periodontal surgery. During the same period, Bone defects were filled with bone graft material, covered with biofilm, postoperative with HBO for 1 week, routine anti-inflammatory treatment and oral care. Six months after the assessment of bone defect regeneration, consider the second surgery and post crown restoration, regular follow-up of 1 year, to assess the stability of bone regeneration. Results: The height and width of bone regeneration around 7 implants all recovered obviously 6 months after operation, and remained stable at 1 year after operation. Conclusion: The clinical effect of using GBR combined with HBO in the treatment of peri-implant bone defects caused by peri-implantitis is ideal.
