Interference from the Gingiva in Overdenture Treatment: Recommendations?
Dr. LT asks:
I have an edentulous patient who has been treatment planned for an implant bar-retained, tissue supported overdenture. The implant fixtures are well placed, stable and have no pathological signs or symptoms. I have not been able to try in the abutments and bar because of interference from the gingiva. After removing the healing abutments which were supposed to form ideal gingival contours, the gingival tissue rebounded and partially covered the implant platforms so that I could not completely seat the abutments or try in the bar. I tried to use mechanical retraction with cord, cotton and epinephrine but the gingival tissue kept interfering with the seating. At this point, I can do some surgical gingival recontouring to free up the implant platforms, but I would like to avoid surgery and I would like to preserve as much keratinized gingival tissue as possible. I could also try to insert wider transmucosal gingival healing abutments to try and mold the tissue off the platforms and create more space. What do you recommend?
