目的评价牙周植骨术联合夹板式金属烤瓷联冠修复牙周骨缺损的临床疗效。方法2008—2009年在新疆医科大学第一附属医院口腔修复科门诊选择患慢性牙周炎伴牙列缺损拟行固定义齿修复的患者15例。应用牙周植骨术联合夹板式金属烤瓷联冠修复基牙牙周骨缺损,随访观察疗效。结果随访观察6个月,治疗总有效率为93.4%。治疗后6个月的各项牙周指标(PD、CAL、BI)均较治疗前有所改善,治疗前后差异均有统计学意义(P<0.05)。结论对于慢性牙周炎伴牙列缺损患者,牙周植骨术联合夹板式金属烤瓷联冠修复基牙牙周骨缺损的近期疗效较佳。
Objective To evaluate the clinical effect of periodontal bone graft combined with splint metal porcelain crown in the treatment of periodontal bone defects. Methods From 2008 to 2009, 15 cases of patients with chronic periodontitis and dentition defect who were scheduled to undergo prosthetic denture restoration were selected in the Department of Oral Rehabilitation, the First Affiliated Hospital of Xinjiang Medical University. Periodontal bone graft combined with splint metal porcelain crown was used to repair the periodontal defects of the abutments. The curative effect was followed up. Results Follow up for 6 months, the total effective rate was 93.4%. All periodontal indexes (PD, CAL, BI) at 6 months after treatment were improved compared with those before treatment, and the difference was statistically significant before and after treatment (P <0.05). Conclusion For the patients with chronic periodontitis and dentition defect, the short-term effect of periodontal bone graft combined with splint metal porcelain crown to repair the periodontal bone defect of abutment is better.
