Management of an old margin located in the furcation
There is ever growing issue as we replace old restorations located on molars. Years ago we were taught to place a margin subgingival and many times these margins approximated the furcations. Cl in the furcation is next to impossible as the more you CL the more coronal bone moves in the furcation. Below we see on #3 the old margin of the crown in fact separating the mesio-buccal and disto-buccal roots. By simply removing the old margin and blending the adjacent roots we can correct the issue without basically affecting the furcation stability. As noted in the fourth photo you can see after removing the old margin how the bone presents itself in the furcation. It has moved coronally. The last 2 photos are at 1 year and 10 years. Perfect Restorative by Dr. Howard Chasolen has created a long term stable environment. Notice how perfect the furcations have been barreled in to the occlusal surfaces allowing for patient and Hygienist management for home care.
