Good absorption of vertical-lateral- frontal stresses

a. Stabilisation planes: the nose and tooth suffer less, the risk of breakage is reduced.

b. Casing in ears and adapter: provides stabilisation of the fit. The ears stay in place.

Pin immobilised

The pin housing is wedge-shaped, thus forcing a maximum adjustment
and guaranteeing correct pin insertion. Moreover, it prevents the
tooth from losing its position with regard to the adapter.
