How far (in mm) should major connectors be from the free gingival margin for the mandible?

2 mm
4 mm
6 mm
8 mm

The correct answer is: 4 mm

The correct distance for major connectors in the mandible is 4 mm from the free gingival margin. This positioning is crucial for several reasons. It allows for adequate space for proper oral hygiene by minimizing the risk of plaque accumulation and inflammation along the gingival margins. By maintaining this distance, the major connectors can help prevent tissue irritation or damage, which is particularly important in patients who may already have compromised gingival health. Moreover, positioning the connector too close to the gingiva could obstruct blood flow and lead to discomfort or ulceration of the tissue. The recommended measurement also ensures adequate framework stability while allowing for optimal retention and support of the prosthesis. Understanding the anatomy and biology of the oral tissues is essential in prosthetic design. Therefore, adhering to the 4 mm distance is important for both the longevity of the prosthesis and the overall health of the patient's oral environment.
