6. New Injection Dynamics with the STA System
Timing the exact moment that a drop of anesthetic is going to be expressed from
the STA Wand™ handpiece takes some practice. It is recommended that a
cotton tip applicator be placed close to the site of injection to absorb any
anesthetic solution which is expressed from the needle prior to penetration into
the tissue and when the needle is removed from the tissue.
The ControlFlo™ (slow) rate is used during the initial stage of all injections.
Maintaining the slow anesthetic drip during careful, slow penetration of the
needle helps to create an anesthetic path within the tissue. This should be done
even if penetration is only a few millimeters. In denser tissues such as the palate
or periodontal ligament space, the slow rate of injection should be maintained
through the entire injection process. Other injections such as the inferior alveolar
nerve block or maxillary mucobuccal fold infiltration are initiated with a slow
penetration and slow rate. Once the needle reaches the target landmark,
aspiration is initiated and if negative, the faster RapidFlo™ or TurboFlo™ rate of
injection can be employed. Aspiration can be repeated at any time during the
injection by releasing pressure from the foot control.
