Hanau’s Quint

Hanau, contemporary American dentist] The five determinants or variables that affect occlusal contacts. They are the orientation of the occlusal plane, the mandibular condylar guidance, the incisal guidance, the cuspal angle, and the compensating curve. From: Hanau’s quint in A Dictionary of Dentistry »

What is Christensen phenomenon?

Quick Reference. [C. Christensen, Danish dentist and educator] A gap occurring in the natural dentition or between the opposing posterior flat occlusal rims when the mandible is protruded (posterior open bite). It can lead to instability in full dentures unless compensating curves are incorporated into the dentures.

What is Lingualized occlusion?

Lingualized occlusion is developed to maintain the food-penetration advantages of the anatomic form while maintaining the mechanical freedom of the nonanatomic form. The lingualized concept utilizes anatomic teeth for the maxillary denture and modified nonanatomic or semi anatomic teeth for the mandibular denture.[3]

What is monoplane occlusion?

Monoplane occlusion involves having non-anatomic denture teeth with a 0˚ incisal guidance angle, arranged on a flat occlusal plane. As a consequence, when patients with monoplane occlusion occlude anteriorly, an interocclusal gap appears posteriorly.

Why is curve of Spee important?

The Curve of Spee is, essentially, a series of sloped contact points. It is of importance to orthodontists as it may contribute to an increased overbite. A flat or mild curve of Spee was essential to an ideal occlusion.

What is denture granuloma?

Epulis fissuratum, also known as denture-induced granuloma, is a benign lesion that forms in response to denture use. If you wear dentures, especially dentures that don’t fit well, you may be at risk of this condition.

What is the buccal shelf?

buc·cal shelf

(bŭkăl shelf) Broad flat surface of the posterior mandible buccal to the teeth or alveolar ridge that provides denture support.

What is combination syndrome?

Combination syndrome (CS) is a dental condition that is commonly seen in patients with a completely edentulous maxilla and partially edentulous mandible with preserved anterior teeth.

What is Bennett shift?

The Bennett movement is defined as “The bodily lateral movement or lateral shift of the mandible resulting from the movements of the condyles along the lateral inclines of the mandibular fossae in lateral jaw movements. “’ McCollum’ considered the Ben- nett movement the most important determinant of occlusion.

What is Lingualized occlusion in complete denture?

Lingualized occlusion (LO), advocated in the 1940s as an alternative to FBBA [4], is defined as denture occlusion that articulates only the maxillary lingual cusps with the mandibular occlusal surfaces in centric working and non-working mandibular positions [5].

Who gave Lingualized occlusion?

This concept was first introduced by Gysi in 1927. His arrangement showed linear cusps of maxillary artificial teeth entering in contact with shallow mandibular teeth depressions. Later on, Payne in 1941 used a 30-degree maxillary tooth to attain a Lingualized occlusion on shallow mandibular depressions.

What is pound triangle?

He recommended that the lingual surfaces of mandibular posterior denture teeth should occupy an area bounded by two lines originating from the mesial surface of the mandibular canine and extending posteriorly to the lingual and buccal aspect of the retromolarpad. This area has been called Pound triangle (5, 8, 9).

Is monoplane occlusion balanced?

Monoplane posterior teeth are generally used in bruxers, and patients with arch discrepancies, poor neuromuscular control and with poor residual ridges. This program describes the arrangement of monoplane posterior teeth to achieve bilateral balanced occlusion.

What is Neurocentric occlusion?

Neurocentric occlusion [11,14,15] That concept has been established by DE VAN in 1954. It is characterized by posterior teeth presenting flat planes in all directions with no medial or lateral inclination.

What is occlusion in prosthodontics?

From Wikipedia, the free encyclopedia. Occlusion, in a dental context, means simply the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest.

What is the normal curve of Spee?

Results: In the deciduous dentition, the curve of Spee is minimal. At mean ages of 4.05 and 5.27 years, the average curve of Spee depths are 0.24 and 0.25 mm, respectively.

Can braces fix curve of Spee?

Exaggerated curve of Spee is frequently observed in dental malocclusions with deep overbites. [1] Such excessive curve of Spee alters the muscle imbalance, ultimately leading to improper functional occlusion. Orthodontists eventually deal with the curve of Spee in virtually every patient they treat.

What is the difference between curve of Spee and curve of Wilson?

[1] The curve of Spee is designed to permit protrusive disocclusion of the posterior teeth by the combination of anterior guidance and condylar guidance, and the curve of Wilson also permits lateral mandibular excursions free from posterior interferences.
