SUG2005 – The Conduction Anesthesia model has (7) contact points on the maxillae and (4) on the mandibular. The model is to be dry injected and once the needle is placed inside the sensor you will hear a noise with a light on the remote indicating the correct injection has been made. The urethane tissue is durable allowing for roughly 200 to 250 injections into the same area before you can see the injection point. The replacement tissue is available to purchase in both pink and semi-translucent colors. The teeth are held in with ortho wax and you can place additional ortho wax on the tooth root and place back in the socket if need be.
***Nissin recommends a 25 gauge needle as anything more narrow (such as a 27 or 30 gauge) will be too thin and prone to bending.***
