The document discusses several newer techniques for local anesthesia delivery systems including vibrotactile devices, computer-controlled delivery systems, jet injectors, and devices for intraosseous anesthesia. It describes technologies like the Dental Vibe device that stimulates sensory receptors to reduce pain, as well as computer-controlled systems like the Wand/Compudent system that allow consistent flow rates. Jet injectors like the Syrijet and Med-Jet H III use high pressure liquid to pierce tissue rather than needles. Devices for intraosseous anesthesia discussed are the Stabident, X-Tip, and Intra Flow, with the Intra Flow allowing one-step entry, injection, and withdrawal. The document concludes by mentioning potential

1. Newer techniques in local
anesthesia delivery systems

BDS II nd year

2. VIBROTACTILE DEVICES

3. Vibra Ject
• Small battery operated
attachment.
• Delivers high frequency
vibration.
• No significant pain
reduction.

4. Dental Vibe
• Cordless, rechargeable,
hand held device
• Stimulates sensory
receptors at injection
site
• Closes the neural pain
gate
• Lights up the area
• Attachment to retract
the lip or cheek

5. Accupal
• Vibration and pressure
• 360 degree proximal to
the needle penetration
• Needle is placed
through a hole in the
head of the disposable
tip.

6. COMPUTER CONTROLLED LOCAL
ANESTHETIC DELIVERY SYSTEMS

7. Wand / Compudent system
• Pen-like grasp
• Foot activated control
• Flow rates controlled by
a computer – thus
consistent
• Demonstrate
measurable benefits

8. Comfort Control Syringe
• No foot pedal
• Five programmed
speeds
• Syringe is bulky and
more cumbersome
• No meaningful
difference in ease of
administration

9. JET INJECTORS

10. Syrijet
• Accepts standard
cartridges
• Permits variable volume
of solution from 0 to 0.2
ml
• Completely
autoclavable.

11. MED – JET H III
• 7 times smaller orifice
than the needle
• Liquid under pressure
pierces the desired
layer
• Accuracy, convenience,
and ease to use

12. DEVICES FOR INTRAOSSEOUS
ANESTHESIA

13. Stabident
• Inexpensive
• Slow speed handpiece
with latch contra angle
and standard syringe
• Perforation to be made
in a reasonably
accessible and visible
location
• Difficult to locate the
perforation site

14. X - Tip
• Initial drill stays in place
– solves the problem
with stabident
• More post operative
pain in males
• No more manufactured

15. Intra Flow
• Single step method –
biggest advantage
• Allows entry into
penetration zone,
injection and
withdrawal
• Start up and
maintenance cost
• Leak anesthesia if not
fitted properly

16. FUTURE TRENDS
NASAL SPRAY SYRINGE MICRO VIBRATOR
