A method to study the relationship between the mobility of human teeth and their supracrestal fiber support was developed. The results of this study would indicate that: (1) The supracrestal fibers do not contribute significantly to the support of a normal premolar tooth. (2) As a human premolar tooth develops moderate to severe loss of osseous support, the relative contribution of the supracrestal fibers to the support of the tooth increases significantly.
一种研究人类牙齿动度与其龈嵴上纤维支持之间关系的方法被开发出来。该研究结果表明：（1）龈嵴上纤维对正常前磨牙的支持作用不显著。（2）当人类前磨牙出现中度至重度骨支持丧失时，龈嵴上纤维对牙齿支持的相对贡献显著增加。
