In addition to the conventional spindle, FORESTADENT memory screws also have an integrated spring which ensures a consistent expansion reserve and even transfer of forces. The elastic spring guarantees a higher patient comfort and quicker expansion, even at low patient cooperation. Readjustment of the screws is only required once the spring deflection is fully exploited.
The Memory Mid-line Expansion Screw, which is available in the second generation, is suited for use in the maxilla and mandible. It allows for a total expansion of 5 mm at a spring force of 500g. The spring deflection is 0.8 mm
- Better patient comfort and quicker expansion due to the elasticity of the spring
- Gentler, as the elastic spring has a constant expansion reserve and provides continuous forces
- Unique, as readjustment of the screws is only required once the spring deflection is fully exploited
