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. 

Dr. Angle’s Headgear from 1894

Need U6 for molar Band placement  Girls = 6.22 years  Boys = 6.40 years 



Other Teeth come in From 6-13 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”

  

Headgear is the “outside” part Facebow goes into patient’s mouth Facebow connects to buccal tube’s “headgear tube”



Buccal tube’s headgear tube accepts facebow wire

Pictured here is the Nitom Locking Facebow

  

Kloehn - Regular - Cushion Loop J-Hook 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 Patented “luggage buckle” style

Patient Needs: • • • • •

Comfortable Easy to Use Attractive Easy to Clean Safe to use

Orthodontist Needs: • • • • •

Patient Cooperation Right force level Safe to use Comfortable Minimal Inventory



NewGear Emphasizes: ◦ Ease of Use ◦ Attractive – color options ◦ Comfort options –  Regular foam cushion  Gel cushion  Visco cushion
