The "7 11 hinge rule" is a guideline in dentistry used to locate the position of the mental foramen, an important anatomical landmark in the mandible. According to this rule, the mental foramen is usually found between the apices of the lower premolar teeth, specifically at a point approximately 7 mm above the lower border of the mandible and 11 mm from the midline. This helps clinicians avoid nerve injury during dental procedures.
