Selection of Artificial Teeth

Vocabulary flashcards for artificial teeth selection, covering anterior and posterior teeth selection criteria.

Bizygomatic Width

The width of the face measured between the zygomatic arches. The width of the six maxillary anteriors is slightly less than one third of this measurement.

Canine Eminences

Landmarks that indicate the corners of the mouth and are used to measure the width of the upper six anterior teeth.

Smile Line

The line representing the highest point of the upper lip when smiling, used to determine the appropriate length and mould of anterior teeth.

Overbite

The vertical overlap of the upper incisors over the lower incisors. A deep overbite results in less lower teeth being shown.

Square Tooth Mould

Characterized by a dominant central incisor, moderate gingival-incisal curvature, and a square residual ridge, indicating a normal bite.

Triangular Tooth Mould

Features a crown that tapers towards the cervical ridge, moderate gingival-incisal curvature, and a triangular residual ridge, often indicating a cross bite.

Ovoid Tooth Mould

Defined by pronounced gingivo-incisal curvature and an oval residual ridge, suggesting an overbite.

Anatomic Form (Posterior Teeth)

Posterior teeth with cusp angles ranging from 20-45 degrees, indicated for patients with normal ridge relationships and well-developed ridges.

Non-Anatomic Form (Posterior Teeth)

Posterior teeth with flat occlusal surfaces (cuspless or monoplane teeth), suitable for cross-bite ridge relationships or TMJ disturbances.

Acrylic Resin (Artificial Teeth)

A material used for artificial teeth, known for being easy to adjust and resilient but less resistant to wear.

Porcelain (Artificial Teeth)

A material used for artificial teeth, characterized by high resistance to wear and abrasion but is brittle and more difficult to adjust.

Waxing Up

The contouring of trial denture bases to reproduce the original form of tissues and conform with the function of lips, cheeks, and tongue for a pleasing facial appearance.

Hue

A specific color resulting from light of a particular wavelength acting on the retina; used in selecting the shade of artificial teeth to harmonize with the patient’s face and hair.

Saturation (Chroma)

The amount of color per unit area; refers to the intensity or purity of the tooth color.

Brilliance (Value)

Equates to the lightness or darkness of a tooth, affected by the dilution of color with black or white.

Translucency

The ability of light to pass through a body without giving any distinguishing image.
