Immediate Pontic Fabrication Using Flowable Resin
Volume 50 : Number 3 : Page 0 : Mar 2016
In 2006, I described a technique for creating a chairside pontic by taking a bite-registration impression of the patient's adjacent or contralateral tooth. The method was presented as an alternative to reshaping a prefabricated denture tooth, which might not be readily available in an orthodontic office. This article describes another option for immediate chairside pontic fabrication, using flowable resin and a mixing pad.
