ABSTRACT
BACKGROUND:
To maintain the long-term effect of ful crown largely depends on the health of periodontal tissues.OBJECTIVE:
To explore the effect of CAD/CAM zirconia al-ceramic crown restoration on the state of periodontal health.METHODS:
Sixty-four abutments of 55 patients were randomly divided into two groupsthe experimental group included 32 abutments of 29 patients which would be restored by CAD/CAM zirconia al-ceramic crowns;the control ed group included 32 abutments of 26 patients which would be restored by Ni-Cr al oy porcelain-fused-to-metal restorations. The volume of gingival crevicular fluid and the levels of interleukin-6 and tumor necrosis factor-αin the two groups were examined at the pre-restoration and post-restoration stages. Meanwhile, periodontal clinical indicators, including sulcus bleeding index, probing depth, plaque index and attachment loss were recorded. RESULTS ANDCONCLUSION:
No difference in various indexes was found in the experimental group before and after restoration (P>0.05). At 12 months after restoration, in the control group, the volume of gingival crevicular fluid, the levels of interleukin-6 and tumor necrosis factor-α, sulcus bleeding index, probing depth, and plaque index were al increased (P>0.05);meanwhile, these indexes in the experimental group were significantly lower than those in the control group (P<0.05). Experimental findings suggest that the CAD/CAM zirconia al-ceramic crown restoration is more favorable to the health of periodontal tissues.
