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](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/41.jpg)
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](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/42.jpg)
You need a slight bend to the needle to allow proper access.
![Page 43: China PPT 2](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/43.jpg)

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](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/45.jpg)
• 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](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/46.jpg)

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

Easy Learn: Bi-rotation
Insertion
Bi-rotation Insertion technique: This technique allows you to minimize needle
deflection during insertion.
How to perform: Rotate needle in a back-n-forth fashion

Easy Learn: 2-Speed Operation
Step - 1
1
2
Using “Normal” mode 2-
speed operation: You can more effectively and efficiently
perform the IA Block using the 2-speeds
How to use:1. Depressing the foot control lightly
allows you to start the injection using
the ControFlo (slower) flow rate –
Use for the first ¼ cartridge of IA
Block
2. Depressing the foot control all the
way down allows the second, more
rapid rate to administer the remaining
volume of anesthetic
![Page 67: China PPT 2](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/67.jpg)
Easy Learn: Aspiration
Step - 2
1
2
3
Using Aspiration to prevent
intravascular needle
placement: You can prevent needle placement into a
vessel by use of aspiration
How to use: After completion of needle
placement:
1. Press and then release foot-control
pedal to activate aspiration, which is
six beeps for the complete cycle
2. If you see blood in the needle
hub, re-position needle and re-
aspirate until negative observation

Easy Learn: Anesthetic
Pathway Anesthetic Pathway
technique: This technique allows you to
penetrate and advance the needle
through the mucosa and soft-tissues
with minimal discomfort to the patient.
How to perform:1. Penetrate mucosa
2. Advancement Pace: 1- 2 mm
then wait 4 seconds to allow
anesthetic to proceed needle
3. Advance needle until contact
against surface of bone

STA-Intraligamentary Injection
Technique: DPS - Dynamic Pressure
Sensing Hold needle steadily in place with minimal
pressure for approximately 15 seconds
Ascending tones and lights will indicate the needle is in the correct injection site, the periodontal ligament space
If ascending tones and lights are not initiated after 15 seconds, move needle slightly until the correct position is attained and lights and tones are seen and heard

pediatric population leading to less disruptive
behavior.

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](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/106.jpg)
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
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](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/108.jpg)
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](https://reader034.fdocuments.us/reader034/viewer/2022042514/559bbe201a28aba81a8b477c/html5/thumbnails/109.jpg)
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
