研究目的:

通过与已上市产品骨填充材料 Geistlich Bio-Oss?进行非劣效对比,评价立心(深圳)医疗器械有限公司研制的可吸收人工骨用于牙槽骨缺损修复的有效性和安全性。  

Objectives of Study:

With the bone filling material Geistlich bio-OSS ? To evaluate the effectiveness and safety of absorbable artificial bone developed by Lixin (Shenzhen) Medical Instrument Co., Ltd. in the repair of alveolar bone defects.

药物成份或治疗方案详述:

(1)试验组:依据受试者存在骨缺损的拔牙牙槽窝情况,植入可吸收人工骨,牙槽窝两侧牙龈黏骨膜软组织袋型翻瓣,翻瓣深度不超过 5mm,依据患者牙槽窝创口形态与大小,选用可吸收生物膜 Geistlich Bio-Gide 进行覆盖,将可吸收生物膜边缘置于龈缘下 3mm,严密缝合牙龈黏骨膜软组织瓣,以固定生物膜和可吸收人工骨;并按要求记录在研究病历中。 (2)对照组:依据受试者存在骨缺损的拔牙牙槽窝情况,植入骨填充材料 Geistlich Bio-Oss?,牙槽窝两侧牙龈黏骨膜软组织袋型翻瓣,翻瓣深度不超过 5mm,依据患者牙槽窝创口形态与大小,选用可吸收生物膜 Geistlich Bio-Gide 进行覆盖,将可吸收生物膜边缘置于龈缘下 3mm,严密缝合牙龈黏骨膜软组织瓣,以固定生物膜和骨填充材料;并按要求记录在研究病历中。 

Description for medicine or protocol of treatment in detail:

(1) Test group: according to the situation of the extracted alveolar fossa with bone defect, the absorbable artificial bone was implanted, and the bag flap of gingival mucoperiosteal soft tissue on both sides of the alveolar fossa, with the flap depth not exceeding 5mm. According to the shape and size of the patient's alveolar fossa wound, the absorbable biofilm Geistlich Bio-Gide was selected for coverage, and the edge of the absorbable biofilm was placed 3mm below the gingival edge, The gingiva and periosteum can be tightly sutured, and the artificial bone flap can be absorbed; And recorded in the study medical record as required. (2) Control group: according to the extraction alveolar fossa with bone defect, the bone filling material geistlich bio OSS was implanted ? The gingival mucoperiosteal soft tissue bag flap on both sides of the alveolar fossa, with a flap depth of no more than 5mm. According to the shape and size of the patient's alveolar fossa wound, the absorbable biofilm Geistlich Bio-Gide is selected for coverage, the edge of the absorbable biofilm is placed 3mm below the gingival margin, and the gingival mucoperiosteal soft tissue flap is tightly sutured to fix the biofilm and bone filling material; And recorded in the study medical record as required
