During setting of lower molar in complete denture lower 6:
- A. 2/3 distance to retro molar pad.
- B. 1/3 distance away of retro molar pad.
During the setting of a lower molar (lower 6) in a complete denture, the ideal position is: A. 2/3 distance to the retro molar pad.
Here's why this placement is preferred:
- Stability:
Placing the tooth too close (option B) to the retromolar pad can interfere with the tongue and cause instability of the denture.
- Function:
The retromolar pad plays a role in speech and swallowing. Having the teeth too far back (further than 2/3 distance) can reduce chewing efficiency.
- Support:
The bony ridge provides the main support for the denture. Positioning the molar at 2/3 distance ensures optimal use of the available ridge for stability.
