Selecting & Setting Teeth - 41<br />
B. Mandible<br />
In the mandible, reference marks should include:<br />
Half way up the retromolar pad - the posterior aspect of the occlusal plane should<br />
intersect the midpoint of the pear shaped pad, to ensure the occlusal plane is not set<br />
too low (can cause tongue biting) or too high (can cause strain as tongue struggles to<br />
place the food bolus back on occlusal table)<br />
Center of the posterior mandibular ridge - Draw this line with a pencil and a<br />
straight edge, on the cast, extending out to the land area. The lingual cusp of the<br />
maxillary posterior teeth should be centered over this line to ensure denture stability,<br />
by reducing fulcruming forces during function<br />
Center of the anterior mandibular ridge - Draw this line with a pencil and a<br />
straight edge, on the cast, extending out to the land area. If the anterior teeth are set<br />
too far anterior to this line, heavy fulcruming forces can cause tilting and dislodging<br />
of the mandibular denture, particularly when the mandibular ridge is severely<br />
resorbed.
