Industry News DENTAL TRIBUNE | Nov./Dec. 201037A (Photos/ Provided by VOCO) Curvy: 3-D shaped anatomical wedges The Curvy Anatomical Den- tal Wedge is three-dimensionally shaped to follow the contour of the tooth. Other wedges bend only two- dimensionally. The synthetic Curvy wedge fol- lows the anatomy of the tooth and will create significantly less tissue irritation and postoperative discom- fort. It will help to adapt the matrix band more precisely for a faster finish of the restoration by achiev- ing more accurate interproximal contacts and less chances for over- hangs. It is easy to insert and remove with cotton pliers. Curvy comes in three different sizes — small, medium and large — in clockwise and counter-clock- wise wedges. For critical marginal adaptation, the clockwise and the counter-clockwise wedges should be used simultaneously from oppo- site sides of the tooth. Curvy wedges are supplied in blue, and the two colors are shaded differently for each size of wedge.

The different colors facilitate quick selection of the required wedges. The wedges with clockwise cur- vature are orange and those with counter-clockwise curvature are By Eugene R. Casagrande, DDS, FACD, FICD, Milestone Scientific The STA intraligamentary injection replaces the PDL and mandibular block There are major differences that should be considered between the traditional PDL injection, delivered with the dental syringe, the Ligma- ject or the Peri-press, and the STA (single tooth anesthesia) (Fig.1) administered intraligamentary injec- tion (STA-II); some of them are as follows: • The PDL is usually the injection of last resort when the mandibular block fails. The STA-II (Fig.2) should be the primary injection for any maxillary or mandibular tooth and can replace mandibular blocks and supraperiosteal infiltrations, which cause collateral numbness to the patient’s lip, face and tongue. • With the PDL, a small amount of anesthetic is injected under exces- sive pressure, which produces a short duration of anesthesia. The STA-II delivers a larger volume of anesthetic under minimal pressure resulting in longer duration (40 min- utes). • The PDL is difficult to admin- ister and the flow rate depends on manual pressure. The STA-II is easy to administer and the flow rate is computer-controlled, consistent and below the patient’s pain threshold. • The PDL is painful on deliv- ery, results in tissue damage and bone resorption and can cause post- operative discomfort. The STA-II is a comfortable injection, and a clini- cal study shows it causes no tissue damage or bone resorption and little or no postoperative discomfort. The STA, using Dynamic Pressure Sensing, allows you to know when you have arrived at the correct site (the periodontal ligament space) for a successful intraligamentary injec- tion. It also indicates if you have left the site and if the needle has been blocked by obstruction or pressure. Check out the simple injection technique for the STA-II below and more on the STA-II on the STAis4U. com website. It’s easy to do. Try it you’ll like it! And so will your patients.

With ShortCut, the cutter is built-in so there is no need for sterile scis- sors to be handy. In addition, the same amount of cord dispenses each time with a simple “click,” easing communication between the dentist and assistant when the need for cord unexpectedly arises during a proce- dure. Many of the dentists and assistants polled on their use of cord in a bottle related issues with communication during a procedure over the length of the cord and having to re-cut or toss out pre-cut cord. With ShortCut, the dentist and assistant have the ability to use the “clicks” to ease communi- cation. Three to four clicks would provide the perfect length for most anterior Using retraction cord in a bottle comes with some notorious hassles that include cord slipping back into the bottle, cord getting tangled, inac- curate lengths and infection control issues. These are just some of the concerns dentists and assistants men- tioned during recent research on their use of retraction cord. While retraction cord in a bottle has been available for more than 50 years, there hasn’t been any revolu- tionary improvement on the system, unlike other areas of dentistry where automix syringes and cartridges have replaced tedious delivery and dis- pensing methods. Enter a simple yet innovative new product from DUX Dental. Introduced during the recent ADA meeting in Orlando, ShortCut is a solution to the problems and concerns dentists and assistants face when using retraction cord in a bottle. ShortCut offers a con- restorations, and four to five clicks would work for posteriors. Further- more, because the cord is encased and the end is unexposed, infection control issues are avoided. Available in cord sizes 0, 1 or 2, ShortCut is pre-loaded with DUX Dental’s GingiBRAID+ retraction cord. The cord can be ordered impregnated with either epinephrine/alum 87 or aluminum potassium sulfate medica- ments. It’s also available as a non- impregnated cord. GingiBRAID is a popular braided cord that has less memory than tra- ditional braided cords and is eas- ily placed into the gingival sulcus without causing gingival bleeding and soft-tissue damage. GingiBRAID works best when it is wet or soaked in a hemostatic agent. Because the bottom line, which depends on efficiency and value, is more important than ever, ShortCut will increase procedural efficiency on many levels.
