1. Abstract
1.1. Background: An overhanging dental restoration extends beyond the boundaries of the cavity preparation. The most frequent causes of gingival irritation and periodontal damage are overhanging and improper dental restorations and prostheses, overhanging margins create the perfect conditions for the buildup of plaque and alter the ecological balance of the gingival sulcus region, which increases the number of disease-associated organisms. According to studies, teeth with overhangs have higher periodontal attachment loss and inflammation than teeth without overhangs.
