脱细胞真皮基质在上前牙GBR种植术中的临床研究

Guide bone regeneration with acellular dermal matrix in the maxillary anterior region

目的研究采用脱细胞真皮基质进行引导骨组织再生技术（GBR）并同期种植体植入的短期临床效果。方法 29例上前牙脱细胞真皮基质进行GBR并同期植入种植体,经软组织塑形后,完成最终上部结构。随访3-9个月,对种植体周围软硬组织进行评价。结果 29例均获得良好骨整合,种植体无松动脱落。种植体周围软硬组织状态良好,美学效果满意。结论采用脱细胞真皮基质进行上前牙GBR并同期植入种植体,短期内可获得较满意的临床效果。

Objective To evaluate the clinical and aesthetic results of guide bone regeneration（GBR）with acellular dermal matrix and implant placement in the maxillary anterior region.Methods 29 cases in the maxillary anterior region were selected carefully, GBR with acellular dermal matrix were processed and the implants were placed immediately.Impressions were taken after soft tis-sue development with provisional implant restorations and the definitive restorations were finished.The follow-up time was 3 to 9 months.The evaluated indexes involved marginal bone level at mesial and distal aspects of the implants,the interproximal papilla in-dex score of Jemt′s classification and the level of the labial soft-tissue margin.Results 29 cases were good bone integration,implant without mobility.Hard and soft tissue around implants in good condition,aesthetic effect was satisfied.Conclusion Using acellular dermal matrix to come forward to tooth GBR and implanted implant during this period,can obtain satisfactory clinical effect in the short term.
