This laser technique (troughing) all but eliminates one of the most frustrating, unpredictable and time-consuming procedures in the dental office – packing retraction cord. Getting a perfect impression the first time is not luck; it is a matter of using proper technique.
Advantages
By using the Styla, StylaOrtho, SoftLase Pro® or OrthoLase® you are able to obtain bloodless impressions with clearly exposed margins within seconds. There is no worry about the instrument inadvertently coming in contact with adjacent metal restorations and shocking the patient, as occurs with the use of electro surgery. Lasing improves visualization of prepared crown margins and aids in hemostasis so crowns and bridges are sure to fit properly every time. Another advantage is that tissues look great at the cementation appointment without recession.
Technique and Laser Settings
After crown and bridge tooth preparation, employ the use of an initiated tip in a continuous mode of operation utilizing 1.0-1.4 Watts. Place the fiber approximately 1-2 mm below the crown margin and gently circumscribe the margin 360 degrees, always keeping the working angle parallel to the long axis of the tooth. Hemostasis and delineation of the crown margin will happen at the same time. If there is slight residual bleeding or any tissue tags, utilize a hemostatic agent such as Superoxol or Astringedent with a disposable fuzzy infusion tip. Wash and dry the preparation and take your final impressions immediately. You do not have to wait.
