Posterior Extrusion
Type I & type II Posterior Extrusion
Type I is used commonly in lower arch with rotation of buccal segments
using 3piece extrusion arch or continuous extrusion arch.
Type II extrusive mechanics is commonly used in the upper arch when
parallel extrusion of posterior segments, using both an extrusion arch
& a cervical headgear with a high outer bow.
Class II elastics cause extrusion of lower molars and upper incisors.
Class II bow causes extrusion of lower posteriors only.

Distalization & Bite opening
Using Class II Bow & Rikanator
Class II bow is a 0.045 steel archwire with hooks for elastic traction.
This is inserted in 0.045 gingival headgear tube with stops welded
mesial to the tubes.

www.indiandentalacademy.com
Rikanator is a type of
fixed bite plane. It is
welded lingual to molars
with a acrylic ram in the
anteriors to open the bite.
It is used only when
anteriors
are
having
correct inclination and
angulation.
