The mandibular alveolar ridge is narrower than the maxillary ridge in denture fabrication, with various anatomical landmarks crucial for support and retention, such as the labial and buccal frenum, lingual frenum, and retro molar pad. Specific regions like the labial and buccal vestibules and the alveolar lingual sulcus are essential for denture design, utilizing muscles like the mentalis and buccinator for stability.
Insights
- The mandibular alveolar ridge, while narrower than the maxillary ridge, plays a critical role in denture construction.
- The lingual frenum, unique to the mandibular arch, is associated with the tongue and genial glossus muscle, highlighting the distinct anatomical features between maxillary and mandibular structures.

Recent questions
What is the difference between the mandibular and maxillary alveolar ridges?
The mandibular alveolar ridge is narrower than the maxillary ridge, which is essential for denture fabrication due to the anatomical variations in the oral cavity.
Where is the labial frenum located in the oral cavity?
The labial frenum is present in both the maxillary and mandibular arches, with the orbicularis Oris muscle attaching to the labial frenum in the mandibular arch.
What is the function of the lingual frenum in the mandibular anatomy?
The lingual frenum, unique to the mandibular anatomy, is associated with the tongue and genial glassess muscle, playing a role in tongue movement and oral function.
What muscles attach to the buccal frenum in the patient's cheeks?
The orbicularis Oris and Buxton Eider muscles attach to the buccal frenum present on both sides of the patient's cheeks, aiding in oral muscle function and movement.
Why is the retro molar pad important for denture support and retention?
The retro molar pad, located at the posterior boundary of the buccal vestibule, provides support and retention for dentures, with attachments from various muscles like the temporalis muscle and superior pharyngeal constrictor muscle.
