Common mistakes
The dentist recommended a crown.The dentist recommended a jacket crown.
错误：使用泛称"crown"代替特指"jacket crown"。"crown"可指多种牙冠，而"jacket crown"特指覆盖整个牙体的甲冠，在医学语境中应使用精确术语。
He got a jacket crown for his tooth.He got a jacket crown on his tooth.
错误：介词使用不当。表示牙冠安装在牙齿上应用"on"而非"for"，这是受中文"为牙齿做牙冠"的影响，但英语中固定用"on"表示放置部位。
