The curvature of the occlusal plane of dentures, created to permit balanced occlusion, to
compensate for the paths of the mandibular condyles as the mandible moves from centric to eccentric positions
. See also curve of Spee. From: compensating curve in A Dictionary of Dentistry »
What are the curves of occlusion?
n.
A curved surface that makes simultaneous contact with the major portion of the incisal and occlusal prominences of the existing teeth
. The curve of a dentition on which the occlusal surfaces lie.
Are compensating curves present in natural dentition?
these curves are present is
natural dentition
. in complete denture occlusion we called then compensating curves. they are required when we make balance occlusion in complete dentures which improves the stability of dentures and also mastication.
What is Christensen phenomenon?
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 dental balanced occlusion?
Background/aim: Balanced occlusal arrangement of artificial teeth and balanced occlusion is
a specific type of occlusion that preserves the stability of complete dentures
. Balanced occlusion comprises realization of tooth contacts at the working side as well as at the balancing side, at the same time.
Where is the curve of Wilson seen?
The curve of Wilson is the
across arch curvature or posterior occlusal plane
. Arc of the curve, which is concave for mandibular teeth and convex for maxillary teeth are defined by a line drawn from left mandibular first molar to right mandibular first molar.
Why is the compensating curve important?
The compensating curve
enables one to increase the effective height of the cusps without changing the form of the teeth
.
Who gave curve of Spee?
The curve of Spee was described by
F. Graf von Spee
[2] in 1890. Spee was a German anatomist (1855–1937) who wrote an original article in 1890 and it has been recently represented in 1980.
What are the types of occlusion?
-
Underbite. One of the types of occlusion is the underbite. ...
-
Overbite. This is the complete opposite of underbite. ...
-
Crossbite. Another type of teeth occlusion is the crossbite. ...
-
Crowding. ...
-
Overjet. ...
-
Open Bite.
Who gave the concept of Lingualized occlusion?
The concept of lingualized occlusion was developed by
Dr. Alfred Gysi
of the University of Zurich. Gysi was granted a U.S. patent for his Cross-bite Posterior Teeth which were manufactured by the Dentist’s Supply Company of New York.
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.
How can Christensen phenomenon be prevented?
The space that occurred between the upper and lower posterior teeth is called Christensen phenomenon. In order to avoid this phenomenon
the curves Spee and Wilson must be constructed.
What is Realeff effect?
This characteristic feature of mucosa is due to its resilient nature which Hanau has described as “Realeff” or
resiliency like effect
. Mechanical or pathological reasons cause fibrous changes in residual ridge, making it resilient it is more commonly seen in mandibular resorbed ridges and maxillary anterior ridges.
What is the working side in occlusion?
The term working side is still most commonly used to describe
the side to which the mandible is moving during a lateral excursion
. A working side interference is a posterior contact on the working side, which interferes with the ideal anterior guidance.
How do you achieve a bilateral balanced occlusion?
Bilateral Balanced Denture Occlusionn Traditionally bilateral balance was achieved with
anatomic posterior denture teeth
. However, it can be achieved with nonanatomic teeth using balancing ramps or by manipulating the compensating curve.
What is non balanced occlusion?
Occlusion according to The Glossary of Prosthodontic Terms Ninth Edition is defined as ‘the static relationship between the incising or masticating surfaces of the maxillary or mandibular teeth or tooth analogues’. ... Non-balanced occlusion is
seen when teeth do not occlude in simultaneous contacts.
