What is sphere of Monson?
What is sphere of Monson?
[G. S. Monson (1869–1933), American dentist] The curve of occlusion of natural teeth in which each cusp and incisal edge touches or conforms to a segment of the surface of a sphere 20.3cm (8in.) in diameter, with its centre in the region of the glabella. See also compensating curve.
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.
What is Pound’s 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).
What is anti Monson curve?
anti-Monson curve – in dentistry, a curve of occlusion which is convex upward. Synonym(s): reverse curve. Monson curve – the curve of occlusion in which each cusp and incisal edge touches or conforms to a segment of the surface of a sphere 8 inches in diameter, with its center in the region of the glabella.
What is dental MIP?
Centric Relation vs. Centric occlusion describes your lower jaw’s position when all your teeth come together when you take a bite. Spear Education explains that it’s the complete intercuspation (meshing together of the cusps) of the opposing teeth, also known as maximum intercuspation (MIP).
What is Christensen phenomenon?
[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 the 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.
How is the curve of Wilson formed?
Aligning both maxillary and mandibular posterior teeth with the principal direction of muscle contraction produces the greatest resistance to masticatory forces and creates the inclinations that form the curve of Wilson.
What is a Lingualized occlusion?
Lingualized occlusion is a set‐up technique developed to enhance denture stability in such patients. In a lingualized occlusion scheme, buccal cusp contacts are eliminated to alleviate lateral stresses or lateral dislodging forces.
What is the Bonwill triangle?
Bonwill (1833–99), American dentist] A 4-inch equilateral triangle formed by lines joining the medial contact point of the mandibular central incisors and the centres of the mandibular condyles.
What is ICP and RCP?
The first tooth contact when the mandible is in the THA position is called the retruded contact position (RCP). In most dentate patients (>90%) there is an anterior and upward slide into intercuspal position (ICP). On protrusion the anterior teeth guide the mandibular movement – so called anterior guidance (A).
