The sanitary pontic is ideal for the mandibular posterior region because it provides adequate tissue clearance without contacting the ridge, facilitating easier cleaning and maintenance. This design minimizes the risk of food impaction and plaque accumulation, which are common challenges in lower posterior areas due to limited access. Additionally, it avoids excessive pressure on the soft tissue, reducing the potential for irritation or soreness. The sanitary pontic’s hygienic design is crucial for maintaining periodontal health in this region where the ridge is often broad and flat, and esthetics are less critical. This approach promotes long-term success of the prosthesis with minimal complications.
