History of Ceramic Materials

• Widespread use in Europe and Japan in the 70s, 80s and 90s
• In 1985, sales of ceramic on ceramic couples were halted
– Poor clinical results
• Ceramic femoral heads on polyethylene available since 1989
• In Feb. 2003, alumina ceramic on ceramic was cleared by the FDA

What is BIOLOX® delta Ceramic?
• The fourth generation ceramic material for orthopaedics
• Alumina/zirconia composite matrix
– Current ceramic products are high purity alumina ceramic
• Improved wear characteristicsand fracture toughness vs.alumina ceramic

Material Properties of Ceramics
Strength
fracture toughness
hardness
stability
Material properties of ceramics
• Strength refers to a material’s ability to withstand applied loads
• Fracture toughness is a measure of a material’s resistance to crack propagation under stress

History of Ceramic Materials
陶瓷材料（即硅酸盐材料）的历史

• Widespread use in Europe and Japan in the 70s, 80s and 90s
于七十年代、八十年代以及九十年代，在欧洲和日本广泛应用（普及）。
• In 1985, sales of ceramic on ceramic couples were halted
在1985年，陶瓷制品的销路止步不前。
– Poor clinical results
初步（拙劣的）分析结果
• Ceramic femoral heads on polyethylene available since 1989
自从1989年，陶瓷材料迎合聚乙烯。（陶瓷迎面聚乙烯）
• In Feb. 2003, alumina ceramic on ceramic was cleared by the FDA
在2003年2月，陶瓷制品中的矾土陶瓷被食品药品管理局通过（澄清）。
——注：“FDA”指的是“FOOD AND DRUG ADMINISTRATION”

What is BIOLOX® delta Ceramic?
……这个不清楚……（delta是好象是第“4”的意思）
• The fourth generation ceramic material for orthopaedics
用于整形外科的第四代陶瓷
• Alumina/zirconia composite matrix
矾土/氧化锆合成（复合）机制
– Current ceramic products are high purity alumina ceramic
现今的陶瓷产品是高纯度陶瓷制品。
• Improved wear characteristicsand fracture toughness vs.alumina cer
