space MAINTENANCE
FIVE MAJOR
- band - crown and loop
- distal shoe
- removable - partial denture type
- lingual holding arch
- nance appliance
pendulum-pendx is what type
fixed appliance
pendulum-pendx is what type
fixed appliance
pendex aka pendulum pendex can expand palate + ___?
yes expand then distilize to gain space
distal jet use what arch
maxilla - regain space
hyrex is
hygenic rapid expander – so rapid palatal expander WITHOUT ACRYLIC
KD appliance used for
correction of anterior crossbite
goal in treating skeletal imbalances
- try to redirect jaw growth
- correct molar and skeletal relatioships
- allow growth to continue in balance
when early tx?
primary or mixed – as soon as patient can tolerate impressions
why early treatment - broad
to correct disharmonies and allow balanced growth and development of CFACIAL AND DENTO ALVEOLAR STRUCTURES
SPACE MANAGMENT
TRANSVERSE PROBLEMS
SKELETAL IMBALANCES (sp class III)
HABITS
quad helix vs TPA
wuad helix can do some rotation to the molars as well
both can do the dental expansion with transverse
bonded expander use
PREVENTS MOLAR EXTRUSION / OPEN BITE– BONDED OVER OCCLUSAL SURFACES WITH THICK LAYER OF ACRYLIC
patients with long face – already vertical dimensino increased - we have to be careful not to increase vertical
ones that are not bonded can tend to have an extrusive movement on the molars
Age limitation on palatal expansion
suture fusion – mid to late teens
high pull head gear for
maximum vertical control
open bite tendency
mandibular plan angle high
striaght pull
more horiixontal force
