The Twin Block with Herbst & Lip Bumpers combines separate upper and lower acrylic plates in a custom-made, removable set. The complete construction is made to your existing bite and includes a front wire bow and stainless-steel wire components.
Two Herbst telescopic assemblies connect the upper and lower plates, one on each side. Each assembly consists of a metal tube, a sliding rod, and attachment screws, creating the distinctive side connections of this design.
The built-in lip bumpers have acrylic pads positioned in front of the upper and lower teeth, behind the lips. Both pads are included as standard. Each plate also contains one genuine orthodontic expansion screw positioned across the acrylic base.
The upper plate is available with full palatal coverage or a reduced-coverage horseshoe design. The horseshoe version leaves more of the central palate area open while retaining acrylic around the screw.
The product photographs show optional headgear tubes on the upper plate. These are not included in the standard set and are supplied only when selected with your order.

Ich trage diese Spange nun schon seit einem Jahr und sie passt perfekt.
Sie füllt den Mund ziemlich aus und sprechen ist nur bedingt möglich.
Die Teleskopstangen halten den Unterkiefer gut in Position, fühlt sich wirklich gut an.
