作者用氧化铝陶瓷根管锥形尖结合根尖切除术行根管倒充填治疗牙齿。牙再植条件是:1.再植牙有保留价值;2.仅有很小牙周骨破坏,3.再植牙的牙周组织及根关部无炎症表现.牙移植时除具备上述条件外还必须;1.牙齿应不大于移植部位的间隙,2.移植床的骨应能保留,3.口腔内无急性炎症表现。作者所采用的再植和移植方法是:只选择上下颌磨牙区个别牙进行观察。移植或再植牙齿拔除或用切骨术拔除后,注意勿损伤所附着的牙周膜。牙齿在口腔外不应超过20分钟,以防止牙周膜坏死。切除根尖部1/4牙根,同时要用生理盐水冷却。用氧化铝陶瓷钉作根管倒充填。将再植牙重新植回到牙槽窝内,用小夹板
The author uses alumina ceramic root canal conical tip combined with apical resection canal root filling treatment of teeth. Replantation conditions are: 1. Replantation of teeth have retained the value; 2. Only a small periodontal bone destruction, 3. Replantation of periodontal tissue and root of the Department of inflammation showed no performance except during dental transplantation with the above conditions Outside must also; 1. Teeth should not be greater than the gap of the transplant site, 2. The bone graft bed should be retained, 3. Oral no acute inflammation. The method of replantation and transplantation used by the author is as follows: Only the individual teeth in the maxillary mandibular molars area are selected for observation. Implantation or replantation tooth removal or removal with osteotomy, taking care not to damage the attached periodontal ligament. Teeth outside the mouth should not exceed 20 minutes to prevent necrosis of the periodontal ligament. Apex root excision 1/4 root, while using saline cooling. Using alumina ceramic nail for root canal filling. The replantation replantation to the alveolar nest, with a small splint
