Minor connector for a mandibular distal extension base should extend posteriorly about?

Half of the length of edentulous ridge
2/3 of the length of edentulous ridge
3/4 of the length of edentulous ridge
The full length of edentulous ridge

The correct answer is: 2/3 of the length of edentulous ridge

The minor connector for a mandibular distal extension base should extend posteriorly about 2/3 of the length of the edentulous ridge. This is because extending the minor connector too far can cause irritation to the soft tissues in the area, while not extending it enough can compromise the stability of the denture. Option A, which states that it should extend half of the length of the ridge, may not provide enough stability for the denture and can lead to movement while eating. Option C, extending 3/4 of the length of the ridge, may be excessive and result in unnecessary discomfort for the patient. Option D, extending the full length of the ridge, can also cause irritation and discomfort for the patient. Therefore, option B is the recommended length for the minor connector as it provides a balance between stability and comfort.
