Performing

STA-Intra-ligamentary

Injection

Page 40: China PPT 2

Easy Learn: Cruise Control

What is the Cruise Control feature: The feature allows you to deliver

anesthetic solution without the need of continuously depressing the foot pedal, it’s analogous to cruise-control in your car in which you release the accelerator and continue to drive.

How do you activate:1. Start injection by depressing

pedal

2. After 3 seconds voice prompt will say “Cruise”

3. Immediately release foot off pedal to remain in cruise mode

How do you de-activate: Tap foot-control pedal to stop

Step - 1

Page 41: China PPT 2

Easy Learn: STA-IL Insertion

Site Area effected:

Single Tooth Anesthesia

Injection site:1. Start on distal

2. Bend needle, if necessary, to

gain access

3. It is best to maintain a direct

view of the needle and it’s

entrance to the sulcus at all

times

4. It is important for the shaft of

the needle to be parallel with

the surface of the root

Step - 2

Page 42: China PPT 2

You need a slight bend to the needle to allow proper access.

Page 43: China PPT 2
Page 44: China PPT 2

NOTE: You cannot access the distal of the lower

molars properly without bending the needle slightly.

Incorrect Correct

Unbent needle Bent needle

(allows proper angle and access to PDL)

Page 45: China PPT 2

• Important to maintain direct vision of proper needle

angle and needle entrance into the sulcus when using

either approach

• Distal-buccal requires needle to be bent as well

Buccal Approach

Page 46: China PPT 2

Mesial Approach

Incorrect needle

angle and entrance

Correct

• Proper angle and entrance can be achieved with bent or straight needle

Incorrect

Page 47: China PPT 2

Objective of Insertion:1. Needle tip to entrance of PDL

Angle of Insertion:1. 30 to 45 degrees

2. Bend needle, if necessary

3. Direct vision of needle

4. Needle shaft parallel to root

Movement of Insertion:1. Very SLOWLY advance needle

producing Anesthetic Pathway

2. Needle is inserted like a

“Periodontal Probe”, gently

Easy Learn: Dynamic Pressure

Sensing

What is the DPS feature: This feature provides real-time audible and

visual feedback to indicate when the needle is properly positioned when performing the STA-Intra-ligamentary (PDL) injection.

How to use:1. In STA-Mode only

2. Start injection

3. Insert needle into “assumed” correct PDL injection location

4. Wait approximately 10-15 seconds in “assumed” correct location

5. Listen & Watch, “ascending tone” & Increase of Pressure Scale through “orange” LED zone

6. Maintaining the High “orange” or the “green” LED zone throughout confirms proper needle location

Step - 4

Easy Learn: DPS® technology

Trouble Shooting:

Problem:Pressure not building:

1. Insufficient hand pressure on

STA/Wand handpiece

2. Did not wait 10 -15 seconds to

allow pressure to build

3. Incorrect needle position

Over-Pressure Alert:

1. Excessive hand pressure on

STA/Wand handpiece

hand pressure into PDL tissue

3. Incorrect needle position

Dr. Bill’s Helpful Tips

Needle choice o 30 gauge for all

o 1” for older children mandibular blocks

o ¾” for infiltration and blocks in younger

children

o ½” for STA (periodontal ligament injection)

Page 106: China PPT 2

Break the Wand for any injection to better

“cup” the needle

Mark the bevel with a permanent marker

Bend the needle with caution, as

needed, for a better angle

Dr. Bill’s Helpful Tips

Page 107: China PPT 2

Dr. Bill’s Helpful Tips

Instrument location - LED’s should be

clearly visible to operator & within reach

Start instrument prior to injection to avoid

startling the patient

Use cruise control- NEVER turbo w/

pediatric patient

Page 108: China PPT 2

Dr. Bill’s Helpful Tips

Avoid dripping the anesthetic in the mouth -

the bitter taste is the easiest way to lose a

compliant patient

Develop a consistent pattern of injection

site (distolingual is best due to anatomy if

manageable)

Page 109: China PPT 2

Rule of 2’s for STA: o 20 seconds MAXIMUM time to be in one

location

o 2 minute window to begin procedure

o 20 minutes to complete treatment

Summary

Audible & visible assurance of pulpal anesthesia

Painless- minimizes disruptive behavior

Immediate onset of anesthesia

o no delay is important for a child’s short attention span

o saves chair time

Multiple quadrants at the same visit

No soft tissue numbness - no risk of lip biting
