Posterior Tooth Selection<br />
Indications<br />
Posterior Tooth Selection<br />
Indications<br />
Anatomic<br />
Non-anatomic<br />
Anatomic<br />
Non-anatomic<br />
Well coordinated patient<br />
Poor neuromuscular control<br />
(Bruxers, CP, etc.)<br />
Previously successful with<br />
anatomic dentures<br />
Previously successful with<br />
monoplane dentures or<br />
severely worn occlusion on<br />
previous denture<br />
Posterior Tooth Selection<br />
Indications<br />
Posterior Tooth Selection<br />
Indications<br />
Anatomic<br />
Non-anatomic<br />
Anatomic<br />
Non-anatomic<br />
Class I ridge relationship<br />
Arch discrepancies<br />
› Class <strong>II</strong> or <strong>II</strong>I or cross-bite<br />
Denture opposes natural<br />
dentition<br />
Immediate dentures<br />
› Except when opposing natural<br />
dentition<br />
Anatomic Occlusion<br />
Lingualized Occlusion<br />
Advantages<br />
Definite point of positive<br />
intercuspation may be<br />
developed<br />
Esthetically similar to natural<br />
dentition<br />
Tooth-to-tooth and cusp-tocusp<br />
balanced occlusion can<br />
be achieved<br />
Maintains some shearing<br />
ability after moderate wear<br />
Disadvantages<br />
Difficult to set<br />
Less adaptable to arch<br />
relation discrepancies<br />
Horizontal force<br />
development due to cusp<br />
inclinations<br />
Harmonious balanced<br />
occlusion is lost with denture<br />
base settling<br />
Requires frequent follow-up<br />
and may require more<br />
frequent relines to maintain<br />
proper occlusion<br />
Indications<br />
High esthetic demands<br />
Severe mandibular ridge<br />
atrophy<br />
Displaceable supporting<br />
tissues<br />
Malocclusion<br />
Previous successful denture<br />
with lingualized occlusion<br />
Advantages<br />
Good esthetics<br />
Freedom of non-anatomic<br />
teeth<br />
Potential for bilateral balance<br />
Centralizes vertical forces<br />
Minimizes tipping forces<br />
Facilitates bolus penetration<br />
(mortar and pestle effect)
