摘　　要：传统分类法根据卡环与一、二、三类观测线的关系将卡环分成三型。即圆环形卡环、杆型卡环和锻丝卡坏。该理论不仅有探讨之处,而且在卡环的设计原则以及临床应用上还存在矛盾。笔者提出一种新的分类法,即根据卡臂的走向和放置位置与观测线的关系将卡环的卡臂分成三型,根据卡环的固位臂类型将卡环分成二型。此分类法概念清楚,有利指导临床卡环的设计和应用及指导初学者在技术室制作卡环。Clasps were classified traditionally into the following three types: cricumferentialclasp, bar clasp and wrought clasp. The criteria chosen in this classification were therelation between class 1, 2, 3 and the surveying line. This dogma is open to discussion.The author put forth a new method for classification. The design was introduced indetail.
