Superior sealing Applying ParaBond Adhesive prior to cementation with ParaCore effectively seals and protects the restoration against marginal microleakage to minimize the risk of postoperative complications. An independent In-Vitro study 1 compared the amount of microleakage present following cementation of

all-ceramic crowns using different composite luting cements. Cross-sectioned human molars demonstrated significant differ- ences in the amount of dye penetration (marginal microleakage) after thermal cycling.

Cementation with ParaBond

The total score between 0 (no leakage) and 8 (total leakage across preparation) was generated by adding scores from the left & right sides together. The Mann- Whitney non-parametric test showed ParaCore with statistically significant better scores (e.g. less dye leakage) than: „ seT (P < 0.001) „ Maxcem Elite (P = 0.002)

no leakage leakage from crown margin reaching axial wall leakage on axial wall, but not occlusal surface leakage as far as occlusal surface leakage to mid point of occlusal surface

Composition

Optimal bond interface

■ ParaCore complies with ISO 4049 ■ Layer thickness 5 | 25 ml 15 µm ■ Shrinkage 5 | 25 ml 3.5 % ■ Water absorption 5 | 25 ml 18 | 16 µg/mm³ ■ Solubility in water 5 | 25 ml 0.7 | 0.6 µg/mm³

■ Methacrylates ■ Dental glass ■ Amorphous silicic acid

Applying ParaBond inside the root canal before post cementa- tion creates an optimal bond interface between the dentin- cement-post to enhance the retention of the post inside the root canal.
