    Connect foot control hose to front outlet on drive unit. Hand-tighten snugly. Position drive unit on a flat, level surface within 3’ of patient. (The STA Wand™ hand-piece micro tubing is 5’ long from the drive unit to the handpiece.) Plug the drive unit electrical cord into the back of the unit and then to a power outlet.
  • Page 8 It is critical that the needle is firmly secured to the handpiece. Note: The STA handpiece is also available with a selection of needles that are pre-attached and bonded to the handpiece. The handpiece equipped with the 30 gauge ½...
  • Page 9 When the procedure is completed, firmly press the needle into the cap on the side of STA unit, locking the cap back on the needle. When locked in place and keeping your hands behind needle point, remove the cap with the attached needle from the unit and discard in an approved manner.
  • Page 10 BASIC OPERATION SafetyWand™ Product Description The SafetyWand™ (Fig. 3) handpiece is designed with safety engineered sharps protection to aid in the prevention of needlesticks. Fig. 3 OPERATION: The operation of the SafetyWand™ control tab requires only a gentle and gradual motion to engage or release the control tab which protracts and retracts the needle.
  • Page 11 Load the anesthetic into the SafetyWand™ and attach the cartridge holder to the drive unit by twisting the holder counter-clockwise approximately ¼ turn in the STA drive unit. The STA will automatically purge the air from the tubing and needle. The handpiece is now primed and ready for use.
  • Page 12 BASIC OPERATION Directions for SafetyWand™ Use: Remove the handpiece (with attached needle) from the cap on side of the drive unit. Protract the needle by depressing the back portion of the control tab, gently sliding it forward all the way (Fig. 7), and depressing the forward portion of control tab to lock into the protracted position (Fig.
  • Page 13 BASIC OPERATION Auto-retraction: The needle will automatically retract when released from the protracted position. Place the handpiece on the side of the drive unit when not in use. While still in the retracted state and using the needle cap as a guide, slide the handpiece into the cap on the side of the drive unit.

  • Page 15 BASIC OPERATION Basic Modes of Operation The STA System is equipped with three basic modes of operation. They are: 1. STA mode, which has a single anesthetic injection flow rate. This mode is activated when the unit is turned on.
  • Page 16 BASIC OPERATION Foot Control Operation The foot control supplied with the STA System is an air activated switch. Slight ™ ™ pressure = ControlFlo (1 cc per 207 seconds). Modest pressure = RapidFlo cc per 35 seconds). When selected, additional pressure engages TurboFlo™.
  • Page 17 Cruise Control Function This feature allows the operator to engage the ControlFlo™ without continuously depressing the foot control. This feature is available in the Normal, Turbo and the STA settings. To use Cruise Control: Begin ControlFlo™. Listen to beeps. After 4 beeps a voice will say CRUISE. This opens a 5 second window during which you can activate the cruise control.
  • Page 18 AutoPurge™ Operation The STA System can automatically purge with the AutoPurge™ feature. When enabled, each time a new cartridge is attached to the drive unit the plunger automatically advances, moving the anesthetic through the tubing to purge the air from the system.
  • Page 19 This function is useful when a second or third cartridge is required during a single procedure using the same disposable STA Wand™ and there is no need to purge air from the handpiece and tubing as it was previously purged. This operation will save unnecessary loss of anesthetic solution when using more than one cartridge.
  • Page 20 BASIC OPERATION Plunger Operation When the STA System is first turned on, the plunger retracts and parks in the retracted position. Inserting the cartridge automatically engages the plunger and purges the tubing. The system is ready when the indicator is illuminated, showing a FULL volume.
  • Page 21 “Aspirate” button on the front of the control panel. TO ASPIRATE: Be sure aspiration mode is activated (light on). Aspiration is initiated by lifting your foot from the foot control in STA, Normal or Turbo mode. When the aspiration function occurs, the plunger is retracted a preset distance, then automatically returns to its original position.
  • Page 22 Cartridge Volume Gauge and Audible Cartridge Tone Indicator The STA drive unit monitors the amount of anesthetic used by visual and audible indicators. The front panel of the drive unit has LED indicators which light up showing the amount of anesthetic solution remaining.
  • Page 23 STA-Intraligamentary Injection. Developed by Dr. Mark Hochman, the STA-Intraligamentary Injection represents a new concept in local dental anesthesia techniques. The STA System is the only anesthesia system that provides clinicians with the 3 critical elements of information when performing a STA-Intraligamentary Injection: 1.
  • Page 24 OPERATION Performing the STA-Intraligamentary Injection Turn the STA drive unit to “On”. The system will default to the STA mode. Load and attach the STA bonded handpiece with the pre-attached bonded 30 gauge ½ inch needle and the appropriate anesthetic. The unit will automatically purge the air from the system.
  • Page 25 “clogged”. If the needle is clogged it will need to be replaced prior to reuse. Note: The operator may test for an over-pressure condition by occluding a needle and using the STA mode. The pressure will build in the STA mode and the alarm will sound.
  • Page 26 Therefore, the operator is advised to remove the needle during aspiration, i.e. when the STA drive unit is retracting during aspiration. Based on the auditory and visual pressure sensing feed-back, it is not unusual for the operator to have to reposition the needle several times before locating the proper position of the needle within the periodontal ligament.
  • Page 27 6. The correct injection pressure is indicated when the device repeats ”PDL” and provides the PDL slow tone. The Training Mode is useful for all injections as the STA System is equipped with an audible voice that will explain the various audible indicators. This will assist the user in quickly learning the proper operation of the STA System.
  • Page 28 BASIC OPERATION Global Default Setting The STA unit may be set to a global default by pressing the volume button during power-up. This sets the device to the following: STA Mode is “ON” and set to tones. AutoPurge/Retract is set to “ON”.

  • Page 34 This promotes the accurate placement of the needle and deposition of anesthetic to achieve profound anesthesia. The psychological advantage of the STA Wand™ handpiece is that it does not resemble a syringe and is not threatening in appearance. If anticipatory anxiety is reduced and patient confidence is increased, the entire injection experience is likely to be a more positive one for the practitioner and the patient.

    4. Hand Control and Rotational Needle Insertion Methods The most obvious difference between a syringe and the STA Wand™ handpiece is the delicate manner in which the STA Wand™ can be held and manipulated. Weighing only a few grams, the ultra-light handpiece promotes precise movements and unsurpassed tactile feedback.
  • Page 36 (Diagram A). New Bidirectional Rotational Insertion Since the STA Wand™ disposable handpiece is held in a pen-like grasp, it can be rotated continuously during insertion. A recent investigation has demonstrated that a bidirectional rotational insertion technique (Diagram B) will alter the vector forces responsible for needle deflection, regardless of the needle gauge .
  • Page 37 It relies on the torque of the STA motor to generate a high fluid pressure at low volume. This literally forces the anesthetic into the tissue prior to the actual needle penetration. The technique is as follows: Hochman M, Friedman M.
  • Page 38  Place a sterile cotton tip applicator on the back of the bevel and apply and apply pressure (a).  Activate the STA unit on slow for 6 - 8 beeps to force anesthetic into the tissue  Continue to apply pressure from the applicator and slowly start bi-axial rotation ...
  • Page 39 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.
  • Page 40 TRADITIONAL Traditional Infiltration Technique The STA drive unit and the STA Wand™ handpiece are ideally suited for the administration of traditional injections. A Maxillary Mucobuccal Fold infiltration is initiated with the ControlFlo™ rate – first position on the foot control. The needle is advanced slowly until it reaches the intended target site.
  • Page 41 However, it may not be required to achieve a comfortable penetration. ControlFlo™ is initiated prior to needle penetration of the mucosa. Rotate the STA Wand™ handpiece slightly at the commencement of the injection to reduce pressure required for needle penetration.
  • Page 42 All traditional injections in the maxilla and the mandible are performed following the steps outlined above. When not required, the aspiration mode can be disabled by briefly depressing the aspirate mode button. Light will turn off. CLINICAL TECHNIQUES AMSA Anterior Middle Superior Alveolar (AMSA) Injection Technique The AMSA is an exciting addition to local anesthesia techniques.
  • Page 43 completely within the tissue. The needle movements are extremely slow and gentle during penetration while the slow flow rate is maintained. The needle is reoriented to a 45º angle as it is advanced until it contacts the bone. CLINICAL TECHNIQUES AMSA Perform aspiration.
  • Page 44 CLINICAL TECHNIQUES AMSA REVIEW OF THE AMSA INJECTION TECHNIQUE Prepare the patient for a slow injection experience. Place topical anesthetic on the palatal tissue if desired. Orient a 30 gauge extra-short needle, bevel parallel to the palatal tissue at the landmark which bisects the premolars and is midway between the free gingival margin and the mid palatine suture.
  • Page 45 CLINICAL TECHNIQUES P-ASA The Palatal Anterior Superior Alveolar (P-ASA) The P-ASA is another modified injection for the anterior maxilla. It will allow the operator to achieve bilateral anesthesia of the maxillary incisors and usually the canines from a single needle penetration. In addition to pulpal anesthesia, profound palatal anesthesia of the gingiva and mucoperiosteum as well as moderate anesthesia of the facial gingiva associated with the teeth is achieved.
  • Page 46 be observed (with anesthetics containing vasopressor). Care should be taken upon needle removal to reduce anesthetic solution dripping down the palate. Do not advance the needle beyond 1/2” (1 cm) since the floor of the nose can be penetrated which may lead to an infection. CLINICAL TECHNIQUES P-ASA Note: It is critical that only the slow rate be used for this injection.
  • Page 47 The traditional PDL technique, utilizing 4 injection sites with approximately 0.3 ml of anesthetic delivered at each site, can be administered with the STA System. However, due to the STA System’s innovative DPS™ technology, a modified technique has been advocated to increase success with the PDL Injection.

  • Page 48: Clinical Techniques

    The needle bevel should face the tooth surface and be orientated parallel with its long axis. The STA Wand handpiece can also be broken off to create a very short, easy to control needle holder. The injection is initiated by activating the STA mode followed by a slow penetration of the needle into the periodontal ligament space.
  • Page 49 STA-Intraligamentary Injection Technique REVIEW STA-INTRALIGAMENTARY TECHNIQUE Activate the STA mode to indicate pressure of the anesthetic as it is being injected. Place a gauze pad or cotton roll at the site of injection. Prepare the patient for a slow injection.
  • Page 50 Continue building pressure until the pressure indicator is in the GREEN zone and/or the audio tones are ascending and the STA says “PDL”. CLINICAL TECHNIQUES STA Intraligamentary Continue the slow flow rate until approx. 0.9 ml is deposited (per site) for a molar tooth.
