Origin ProActive

Dr. Paul Feuerstein, DMD


When we create single crowns our focus is on the tooth being restored. Many times the adjacent teeth are virgin or have small restorations. Using a clever crown design we can create a preventive restoration for the adjacent teeth. The Proactive crown is designed and manufactured with the contacts constructed of Resin Modified Glass Ionomer (RMGI). The concept is that the contacted teeth will be constantly be bathed in Fluoride as it is released. Also the nature of RMGI is that it can be recharged when fluoride is applied to it. That can be achieved in small increments with over the counter fluoride toothpastes or higher level prescribed gels and rinses. Since the contacts are not in an occlusal bearing area, there is virtually no wear. Speaking of contacts, if the crown should come in from the lab either too tight or not tight enough, this is a very simple in-office adjustment. Details are in the accompanying video.
