1. Clean denture by brushing with soap and water. Using a sand paper disc, trim down high spots and rough surface around periphery. |
 |
2. To insure a completely uniform bond of the reline plastic to the denture surface, coat denture surface with Lang's Acrylic Primer. If primer is not available, any acrylic monomer painted over denture surface will improve bond. |
 |
3. To protect surfaces not to be bonded, such as acrylic teeth, interproximal areas, outer ridge of denture, opposing denture, any acrylic fillings, jackets, or bridges, coat all surfaces with mineral oil. This prevents the acrylic reline from curing to these surfaces. |
 |
4. Pour a measuring vial of liquid into a mixing cup and then add a measured vial of powder and stir thoroughly with a steel spatula. (The liquid vial measures 6 cc, and the powder vial 10 cc.) |
 |
5. Allow mix to gel for about 2 minutes, or until it reaches the consistency at which you wish to work. |
| |
6. Spread the mix into the ridge area, covering from crest of ridge to periphery. Also spread mix across post dam area. |
| |
7. Place denture into patient's mouth and have patient close jaws slowly to a biting position, bringing teeth into occlusion. Have patient suck in cheeks to muscle trim. |
| |
8. After three additional minutes in patient's mouth, remove the denture and check coverage and muscle trim. Material can be added or trimmed away at this time. |
| |
9. Re-enter denture into patient's mouth for another three minutes, keeping teeth in relaxed occlusion. Remove denture from patient's mouth and allow to bench cure for 20 minutes. |
| |
10. WARNING: DO NOT leave reline plastic to completely self-cure in patient's mouth. The exothermic heat of self-curing can be uncomfortable and can burn tender tissue. Once the plastic reaches a stiff rubberlike state, additional time in the patient's mouth is of no further value. |
 |
11. Let bench cure 1-2 minutes, then place in Lang Aquapres at 30 PSI for 20 minutes. Curing under pressure eliminates porosity, thus making a strong, dense, esthetically superior repair. |
| |
12. After acrylic is cured, wash plastic in cold water. Trim and polish on a lathe at slow speeds. When relining a lower denture, all tissue bearing surfaces of the denture should be covered with acrylic. |
| |
13. Paint Jet Seal over the finished reline. Jet Seal is a surface sealant used to seal hard and soft relines. Jet Seal seals in porosity and increases color stability. |
