异体冻干皮片(freeze d r i ed allogen i(?)skin grafts简称FDSG)应用于口腔已为不少学者研究,Yukna报告FDSG在治疗龈粘膜缺损的患者,可以与新鲜自体粘膜植入媲美。但是未见使用FDSG于前庭成形来保持前庭沟深度的报告。本研究的目的是在动物身上评价FDSG维持前庭沟深度的能力。本研究共用6只成年狗进行实验。首先在气管内插管全麻下拔牙,保留两侧切牙和后磨牙,维持术后正常咬(牙合)关系,拔牙后作齿槽骨修整。拔牙和齿槽骨修整三月后,全麻下检查伤口已愈,制作下颌丙烯酸酯固定模。拔牙和齿槽骨修整后16周,全麻下作前庭成形术,按随机选择在5只动物身上一侧用冻干异体断层皮,0.012～0.015时厚移植,另一侧用自体新鲜断层皮,厚0.012～0.015时移
The application of freeze-dried skin grafts (FDSG) to the oral cavity has been studied by many researchers. Yukna reports that FDSG is comparable to fresh autologous mucosal implants in patients with gingival-mucosal defects. However, there is no report of the use of FDSG in the shape of the vestibular vestibule to maintain the depth of the vestibule. The purpose of this study was to evaluate the ability of FDSG to maintain the depth of vestibular furrows in animals. In this study, 6 adult dogs were used for experiments. First of all, in the endotracheal intubation under general anesthesia, retaining both sides of the incisors and post-molar, to maintain the normal bite (occlusal) relationship, tooth extraction for alveolar bone repair. Tooth extraction and alveolar bone trimming After three months, under general anesthesia to check the wound has been cured, the production of mandibular acrylic stent. Tooth extraction and alveolar bone 16 weeks after dressing, under general anesthesia for vestibular angioplasty, randomly selected on one side of the five animals with lyophilized allogeneic cutaneous, 0.012 ~ 0.015 when the thickness of the transplant, the other side with fresh cutaneous autologous , Thick 0.012 ~ 0.015 time-shift
