Why use Headgear?
Headgear Basic Info
Types of Headgear
Patient needs vs. Orthodontist’s needs



1. Increasing Anchorage
2. Distalizing the Maxillary (or mandibular
arch
3. Precautionary Use
Headgear can create either an orthodontic
change or orthopedic change.



Used to hold or move teeth or entire arch
e.g hold upper (maxillary) arch while child
grows
e.g move back (distalize) upper molars in
relation to child’s head.




Action Desired
Recommended Wear Time
- Distalizing
24 hours per day
- Holding anchorage
14 hours per day
- Precautionary
night time wear
Headgear has been used
Successfully for 150+ years.

Facebows
Release Modules
Straps or cushions
Other items



Headgear is the “outside” part
Facebow goes into patient’s mouth
Facebow connects to buccal tube’s
“headgear tube”

Asher
Bite Plate


Kloehn style facebow
- .045” diameter inner bow
- .072” outer bow
- 6 sizes inner bow
- 2 sizes outer bow
Rigid Feel


Kloehn Loop style
- invented by Dr. Andrews
- .067 outer bow
with cushion loop
Softer springy Feel

J-Hook Facebow
- Two “J” shaped hooks
connect to posted archwires

Asher Facebow
- Used by Dr. Ron Roth
- Intrudes anterior teeth
- Short or regular outerbow
- Pushes on Archwire

Bite Plate Facebow
- Intrudes anterior teeth
- Short or regular outerbow
- Pushes on anterior teeth
- two main styles:
cushion loop style or
regular style

Four Types of Headgear Injuries In Europe
(23 countries studied)




Accidental disengagement while playing (17%)
Incorrect handling during fitting or removal (8%)
Bully Pulls headgear (4%)
Unintentional nighttime disengagement (71%)
Your Actions can reduce Potential Injuries:



Proper patient instructions
Proper fitting by orthodontic office
Proper equipment – Ortho Kinetics Headgear
& Facebows
Injury Cause & Prevention Strategy:
1. Accidental disengagement while playing (17%)
Proper patient instructions and education
2. Incorrect handling during fitting or removal (8%)
Proper patient instruction and education
3. Bully pulls headgear (4%)
Releasable headgear modules
4. Unintentional nighttime disengagement (71%)
Nitom™ Locking Facebow



Our releasable force module’s latches are
designed to release at higher force levels
than competitive modules when pulled slowly
We try to minimize accidental nighttime
headgear module release. (Type 4 injury)
Our design philosophy applies to:
◦ Nitro™ Modules
◦ NewGear™ Headgear

Releasable headgear for modules
◦ Aka. Safety modules or safety breaks, etc.
Fit onto Cervical and high pull
Straps and connect to facebow


When you pull strap; a force
is applied by the module
When strap is fully extended;
module “breaks away”

The Further you pull strap
(strap extension)= more force
applied


Marks on strap show how
far strap is extended
(pulled)
Use OKC Force Tool to see relationship
between force & extension


OKC offers plastic release clips on “Nitro”
Brand Modules
plastic clips are easier to put together



NewGear features plastic
clips with higher breakaway force
It is easy to put together
