Posterior Teeth Selection and Occlusal Form Quiz

What controls the length of upper anterior teeth?

In a patient with a Short lip, how much of the upper central incisor can be seen?

What dictates the width of upper central incisor?

How should the length of lower anterior teeth be aligned?

Which type of posterior teeth is generally considered more esthetic in appearance?

For patients with esthetic concerns, which type of occlusal form teeth should be used to create balanced occlusion?

What does the term 'Cuspal Angulation' refer to in the context of posterior artificial teeth?

Which type of posterior teeth should be selected for patients with weak ridges?

Why should the bucco-lingual width of posterior artificial teeth be narrower than natural teeth?

How should the length of the maxillary first premolar compare to the maxillary canine for proper esthetic effect?

What must be avoided to prevent dislodgment of dentures according to the text?

How is the occluso-gingival height or length of posterior teeth controlled?

Upper Anterior Teeth Length

The length of upper anterior teeth is controlled by the vertical dimension of occlusion (VDO).
Short lips result in only the incisal edge of the upper central incisor being visible.

Width of Upper Central Incisors

The width of the upper central incisors is determined by the width of the inter-canine space.

Lower Anterior Teeth Alignment

The length of the lower anterior teeth should be aligned such that they do not protrude beyond the upper incisal edges when the teeth are in occlusion.

Posterior Teeth Esthetics

Posterior teeth with a cusp height of 2-3mm are generally considered more esthetic due to their natural appearance.

Esthetic Occlusion

For patients with esthetic concerns, balanced occlusion can be achieved using posterior teeth with a cusp height of 2-3mm.

Cuspal Angulation

Cuspal angulation refers to the angle of the cusp slopes on posterior artificial teeth. This angle affects the path of occlusion and can impact function and wear.

Posterior Teeth for Weak Ridges

Posterior teeth with a lower cusp height (less than 2mm) should be selected for patients with weak ridges to prevent excessive pressure and denture dislodgment.

Bucco-Lingual Width

The bucco-lingual width of posterior artificial teeth should be narrower than natural teeth to avoid impinging on the cheeks and tongue.

Maxillary Premolar and Canine Length

The length of the maxillary first premolar should be slightly shorter than the maxillary canine to maintain proper esthetic effect and a balanced appearance.

Denture Dislodgement

To prevent denture dislodgement, it's crucial to avoid excessive horizontal and vertical forces during occlusion, which can be achieved by using balanced occlusion principles and appropriate cusp heights.

Occluso-Gingival Height of Posterior Teeth

The occluso-gingival height or length of posterior teeth is primarily controlled by the vertical dimension of occlusion (VDO).

Test your knowledge on the selection of posterior teeth based on their height and occlusal form. Learn about the esthetic considerations and functional aspects when choosing long, short, or medium posterior teeth. Explore the differences between anatomical and non-anatomical cusp forms.
