Adding to a Pontic - Troubleshooting
Have you ever returned a case to the laboratory with these instructions “The bridge looks and fits great and fits the model, but please add porcelain under the pontic”? This phenomenon may be due to the pontic site deforming during the impression taking process. Anesthesia and packing cord often causes inflammation in the pontic site which can lead to an inaccurate representation of the tissue site in the final impression. When developing pontic sites with provisional restorations, it is suggested that an additional impression of the pontic site be captured immediately following provisional removal, but prior to packing cord for the final impression. Please indicate this is a “pontic impression”.
