摘　　要：种植体周围炎是发生在种植体周围组织中与牙菌斑相关的病理状况,其特征是种植体周围黏膜组织发生炎症性改变,随后支持骨组织逐渐丧失。本文报道1例基于菌斑控制的种植体周围炎引导骨再生治疗病例。患者35牙种植术后4年因“左下后牙肿胀不适2年余”就诊。X线根尖片显示35牙种植体远中骨密度降低,临床诊断为35牙种植体周围炎。35牙种植体经引导骨再生治疗,并进行定期牙周维护,术后3.5、11、18个月和7年复查显示牙槽骨高度及骨密度稳定,牙周探诊深度变浅,但牙龈轻度退缩。本病例7年的随访结果提示,种植体周围炎经过完善的牙周治疗后,临床牙周指标可以获得明显改善,牙槽骨得到良好的修复再生。Peri-implantitis is a pathologic condition associated with dental plaque that occurs in the implant tissue and is characterized by inflammation of the mucous membrane surrounding the implant,followed by the progressive loss of supporting bone.In this study,a case of guided bone regeneration therapy based on plaque control of peri-implant inflammation was reported.Four years after surgery for the left second premolar implant,the patient presented with“left lower posterior tooth swelling and discomfort for more than 2 years”.The X-ray periapical film showed a decrease in distal bone mineral density of implant,and the clinical diagnosis was peri-implantitis of the left second premolar.Implants underwent guided bone regeneration and regular periodontal maintenance treatment.Re-examination at 3.5 months,11 months,18 months,and 7 years showed that the alveolar bone height and bone mineral density were stable,and the periodontal depth became shallow.However,the gingival recession was mild.In the present case,follow-up at 7 years demonstrated that the clinical periodontal indexes could be remarkably improved after complete periodontal treatment for peri-implantitis,and the alveolar bone could be well restored and regenerated.
