The unique short bevel is especially designed for the use in intraligamentary anaesthesia (SeleKt+ needle 30G / 0.3 x 12mm)
Cannulas with an extra short bevel can help reduce the risk of forming hooks and corresponding injuries of the soft tissue.
In vitro laboratory tests showed a significantly lower distortion of the needle tip of our short bevel needles.
F0 – Maximum of the piercing phase
F1 – Maximum of the cutting phase
F2 – Maximum of the dilatation phase
FR – Mean value of the friction phase (55% to 95% of the testing length).
The colour coding of SeleKt+ is based on the wavelength of light and its colour range. The greater the wavelength of the coding colour, the longer the injection cannula. You can therefore select the right needle at a glance.
Intraligamentary anaesthesia (ILA) or periodontal ligament injection (PDL) is a patient-friendly single tooth anaesthetic technique.
The term intraligamentary anaesthesia does not refer to the pathway of anaesthetic agent spread but to the site of needle injection. Therefore the injection needle is inserted about 1-2 mm into the 0.15 to 0.38 mm wide periodontal gap until a slight resistance can be felt.
For best results, extra short bevel needles are recommended (1,2).
