The minor connector should cross the gingival tissue abruptly to prevent plaque accumulation and facilitate proper hygiene. An abrupt crossing creates a clear boundary that minimizes tissue impingement and reduces irritation or inflammation of the gingiva. Gradual or angled crossings can trap food debris and increase the risk of periodontal issues. Additionally, an abrupt design supports the rigidity and stability required for the prosthesis while maintaining healthy soft tissue contours. Ensuring this precise design is crucial for long-term oral health and prosthesis success.
