Final answer:
The modified sanitary pontic provides advantages in improving oral hygiene, reducing food impaction, and enhancing esthetic outcomes for dental bridge patients.
Step-by-step explanation:
The modified sanitary pontic is a design aspect in dental prostheses, specifically for bridges. The advantage of a modified sanitary pontic is that it improves oral hygiene, reduces the risk of food impaction, and provides better esthetics comparing to previous pontic designs. This design allows for easier cleaning by the patient and minimizes the accumulation of bacteria, which can contribute to both dental and gum diseases. The shape of a modified sanitary pontic is such that it does not contact the underlying gum tissue directly, which helps in maintaining the health of the tissue and providing comfort to the patient. Furthermore, since it is designed to resemble a natural tooth, it enhances the esthetic outcome of the dental prosthesis.
