A prospective clinical study of a multipurpose adhesive used for the cementation of resin-bonded bridges.
A clinical trial was conducted to assess comparatively the clinical performance of anterior resin-bonded bridges (RBBs) cemented with Panavia 21 Opaque (PO) or Scotchbond Multi-Purpose Plus (SBMP) used in conjunction with Scotchbond Resin Cement (SRC). Thirty-three bridges were cemented with PO and 31 bridges with SRC. The bridges were assessed six months after placement via a postal questionnaire. Two bridges (one in each group) failed at that stage. Clinical assessments at one year revealed that one PO bridge and five SRC bridges had failed. Chi-squared analysis, however, showed no significant difference (p > 0.05) in the retention rate of the two groups. At the end of two years, eight bridges had failed (three PO and five SRC). Chi-squared analysis again revealed no significant difference in the retention rate provided by the two adhesives. Greyness of the abutment teeth of bridges cemented with SRC was a drawback in using this material. Many operators who participated in the trial felt the use of SRC/SBMP was time-consuming and rather complicated.
