刚玉陶瓷是一种来自铝氧化物的陶瓷,具有生物反应慢、生物相容性、耐腐蚀、坚硬、稳定、绝缘、耐放射等优点。作者用以修复上颌窦和额窦手术中的面部骨孔,重建鼻额管。首先在不同年龄的狗身上作试验。用刚玉陶瓷材料澈成0.5～1mm厚的大小不等的圆形平片和凹片状赝复体。全片各处打一些孔眼,以便结缔组织穿过生长而将其固定。全麻后,按传统方法行上颌窦和额窦手术,然后切除前壁环钻孔边缘处的骨膜,将陶瓷片盖在骨孔上,以表
Corundum ceramic is a ceramic from aluminum oxide with the advantages of slow biological reaction, biocompatibility, corrosion resistance, hardness, stability, insulation and radiation resistance. The author used to repair facial maxillary sinus and frontal sinus surgery in the reconstruction of the nasal tube. First, test dogs of different ages. With corundum ceramic material Che into a 0.5 ~ 1mm thick round flat and concave-shaped prosthesis. Punch holes around the entire piece so that the connective tissue will pass through it and fix it. General anesthesia, according to the traditional method of maxillary sinus and frontal sinus surgery, and then excision of the anterior wall ring perforation at the edge of the periosteum, the ceramic cover the hole in the table
