To explain the strength using technical terms, the SK5 frame, with tension of hardness 57 and the least burden to blood circulation and skeleton, was designed to apply a tension of 9.6N to the face based on inter-jaw size of 140mm.

To put it easier, it was produced to ensure correctional effect providing pressure which does not interrupt the blood circulation.

In addition, the intensity of the pressure can be easily adjusted using the auxiliary product, chin band. using the auxiliary product, chin band.

Therefore, the strength to push the cheek and jaw is very optimal to minimize the interruption of blood circulation. The intensity of the applied force was studied and implemented to maximize the stability and effectiveness.

For a faster correction, adjust the chin band to increase the pressing force. However, too strong pressing force interrupts with blood circulation and causes pain, preventing persistence-the core of facial correction.
