Overhangs can lead to significantly increased accumulation of bacterial plaque, decay, and even potential bone loss.
In my office, I have experienced that about 50% of crowns are too tight, and the Black Diamond Strips cannot get into the interproximal space to adjust the proximal contacts. Occasionally, the crowns are even too wide to fit into the space between two adjacent teeth, which can be very frustrating to dentists.
In natural dentition, there is microscopic clearance or passive contact between teeth when they are in rest position, which is called Interproximal Relief (IR)*, and when a crown is fabricated, it is necessary to adjust the crown on the proximal contact surfaces to restore IR, and to achieve complete marginal seating for patient comfort and functionality.
