Shape: Cylindrical paste
Main ingredients: Urethane dimethacrylate,Silica powder & Organic
and inorganic composite filler
Principle: By photopolymerization, the monomers in the paste
polymerize to improve the viscosity and achieve polymerization and
curing.
Product performance:
The hardness of the lower surface is not less than 70% of the
hardness of the upper surface.
Flexural strength ≥50MPa.
Water absorption value ≤ 40μg/mm3.
Solution value ≤7.5 g /mm3.
Applicable Scope:
The product is suitable for making temporary patches that can be
kept in the mouth for 1-2 weeks.
usage method:
Remove the plug of the syringe, push the syringe push rod, and
intercept appropriate amount of paste with the knife. After
intercepting the paste, cover the syringe head with the plug in
time to avoid the product being irradiated by light.
After wearing gloves, knead the paste repeatedly with your fingers
to make it soft.
Make a shape between the abutment and the adjacent teeth that can
be easily inserted, or insert the paste first between the
abutments.
Apply separation agent on the surface of abutments and adjacent
teeth, press the paste on abutments, and use a knife to shape the
crown contour.
Let the patient gently bite, leave the mark of the occlusal
surface, and then make the occlusal adjustment. Meanwhile, make the
edge adjustment and shape of the buccal tongue side. Use
appropriate equipment to remove excess material as needed. If the
forming operation time is too long, the separation agent can be
applied to fingers and instruments to avoid paste adhesion. Please
discard the rest of the paste.
Temporarily solidify the material in the patient's mouth to prevent
deformation when removed from the mouth. According to the order of
buccal face, adjacent face, maxillofacial and lingual side, the
material was exposed to light, and the temporary crowns were taken
out after temporary polymerization. When taking out, keep the
direction perpendicular to the abutment to avoid temporary crown
deformation.
The temporary crowns were irradiated externally with a light curing
machine (wavelength: 480nm), and each side was irradiated for about
20 seconds for final curing.
Use appropriate equipment for grinding and shaping, and use this
product to add and stack the missing parts.
It is suggested that the temporary crown should be bonded with
temporary crown cement.
