基于软组织间接显影CBCT测量上颌前牙唇侧中央CEJ与骨嵴顶之间的距离、CEJ处牙龈厚度及SOG高度

Measurements of gingival thickness, the distance between CEJ and bone crest, supraosseous gingival height in the maxillary anterior teeth by indirect soft tissue imaging CBCT

Teeth	CEJ-BC/mm, x±s	SOG/mm, x±s	GT/mm, x±s	BT/mm, x±s
* P < 0.05, compared with the other two groups. CBCT, cone-beam computed tomography; CEJ, cemento-enamel junction; BC, bone crest; CEJ-BC, the distance between CEJ and BC; SOG, supraosseous gingiva; GT, gingival thickness; BT, thickness of bone.
