Industry News DENTAL TRIBUNE | September 201034A AD The P-ASA is a single-site pala- tal injection into the nasopalatine canal (Fig. 2), which can produce bilateral anesthesia to six anterior teeth and the related facial and palatal gingival tissues (Fig. 3) with- out causing collateral numbness to the patient’s upper lip, face and muscles of facial expression (Fig. The STA Injection System, a computer-controlled local anes- thetic delivery or C-CLAD (Fig. 1), is not only great for single-tooth anesthesia but is also very use- ful for administering multiple-tooth anesthesia injections such as the palatal-approach anterior superior alveolar nerve block (P-ASA). STA: essential for cosmetic dentistry System works well for P-ASA injections Fig. 1: STA System Fig. 2: Nasal-palatine canal site composites, veneers and crowns because you can immediately assess the patient’s smile line when the lip is used as a reference point. The P-ASA is also useful for end- odontic, periodontal and implant procedures. In fact, it is recom- mended as the primary injection for any or all of the six maxillary anterior teeth. During administration and post- operatively, the P-ASA is a very com- fortable injection for your patients because of the STA computer-con- trolled flow rate below the patient’s pain threshold, the use of minimal pressure and the ability to easily control the needle using the wand handpiece. Check out the simple injection technique for the P-ASA on the STAis4U.com website. Milestone Sci- entific asserts it’s easy to do, you’ll like it and so will your patients.

Using significantly less anesthet- ic, this easy-to-administer injection can take the place of at least four supraperiosteal buccal infiltrations and a palatal injection. It is valuable for cosmetic restor- ative dentistry procedures such as ADA BooTH No. 4131
