1. Measure the length of the retention
2. Ensure a dry working field (Rubber dam)




3. Apply etching gel


4. Apply adhesive system




5. Apply a thin layer of flow composite

6. Adapt Dentapreg™ SFU strip to required position





7. Light cure Dentapreg™ SFU strip

8. Cover the light cured strip with a thin layer of flow composite





9. Light cure flow composite

10. Clean space between the teeth and polish the splint





11. Post-orthodontic retainer reinforced with Dentapreg™ SFU strip

1. Clean the root canal
 2. Measure the length of the required Dentapreg™ SFU
3. Apply adhesive system
4. Cut the Dentapreg™ SFU  to required length
 5. Insert Dentapreg™ SFU  in the root canal
 6. Light pre-cure the Dentapreg™
SFU
7. Remove Dentapreg™ SFU  from the root canal and light cure it
 8. Apply dual curing cement on cured Dentapreg™ SFU
9. Insert Dentapreg™ SFU in the the root canal
10. Clean the overflowing cement in the flaring area
 11. Light cure the cement
 12. Final solution of Dentapreg™
SFU

General Remarks for Working with Dentapreg™ SFU


  • Before forming Dentapreg™ SFU strip on a model, always apply separation liquid or wax
  • Always use the widest clinically acceptable Dentapreg™ SFU strip
  • During forming and adaptation of the Dentapreg™ SFU strip advance slowly from one end to the other to allow for a good adaptation of the fibrous reinforcement and small flow of the resin to avoid defects and shape memory effect
  • In order to minimize potential damage to the fibers, it is recommended to use plastic instruments for dental composites
  • When preparing the strip (measuring, trimming), keep the strip in its original transparent protection foil to avoid contamination
  • Avoid sharp edges and extremely small interproximal curvatures when forming Dentapreg™ SFU strips to prevent fiber breakage
  • Most commercially available light or dual curing dental adhesives can be used to bond Dentapreg™ SFU
  • Adhere according to the acid etching and adhesive  procedures recommended by the manufacturer of etching agent and adhesive
