The whole process of preparing the Comfort-in™ injection system for use in a dental clinic is simple and easy. It should take a few minutes to set up the first time. It will get faster as you become better with each practice.
Open the wings of the pressure lever so that 3 parts of the lever are clearly visible:
Insert the injector head into Injector holder as shown in the pictures above and the video below. Insert the pressure stick into the hole of the injector’s head (as shown in the picture above). With the help of “push bar,” press the “pressure stick” into the injector’s head. You should hear a “click” sound when the injector’s spring is fully loaded.
The Comfort-in injection system has many advantages such as:
- Needle-free injection
- Virtually painless
- Reduces tissue damage and scar tissue
- Reduces psychological inhibitions and fears
- Minimises injection-induced stress
- Elimination of injury to patient and physician caused by needle
- Safe and easy use
- Most economical on the market, being good for up to 10,000 injections
Always have the patient in the supine position for maximum access and comfort. Never inject while the patient is sitting upright as it limits the dentist’s view and access to properly inject.
The initial injection should be a low dose of the anaesthetic drug, between 0.15ml and 0.20ml, as a sensitivity test.
Wait a few minutes and then check the patient for any signs of hypersensitivity. If any are observed stop your dental treatment immediately and create a record of the type of anaesthetic drug as a precaution in the future.
Before injecting, make sure to pull the cheek away from the area at the injection site. After pulling the cheek away, the vestibule will be visible.
Place the tip of the syringe in contact with the vestibule (see image, as well as videos).
While pulling the cheek away from the injection site, adjust the injector to an angle away from the bone so that the injected local anaesthetic solution will be injected directly into the vestibule.
Avoid increasing the injector’s angle because this may cause injury to the bone as the anaesthetic exits the injector at high speed.
