What is the classification of occlusion when the Mesiobuccal cusp of the maxillary first molar is mesial to the buccal groove of the mandibular first molar?

What is the classification of occlusion when the Mesiobuccal cusp of the maxillary first molar is mesial to the buccal groove of the mandibular first molar?

Class II malocclusion: The mesiobuccal cusp of the maxillary first molar occludes anterior to the buccal groove of the mandibular first molar.

What is a talon cusp tooth?

Talon cusp is a dental anomaly also known as an eagle’s talon. It is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. The exact etiology is unknown. The inci-dence of talon cusp is less than 6%.

What is the most distinct characteristic of a maxillary central incisors?

The mesial aspect of the maxillary central incisors is triangular. The base is located at the cervix and the apex at the incisal ridge. A characteristic feature of these specific incisors is that the incisal ridge of the crown and the center of the tooth are perfectly aligned.

What is mulberry molar?

Mulberry molars are a dental condition typically linked with congenital syphilis, characterized by multiple rounded rudimentary enamel cusps on the permanent first molars. Mulberry molars are actually defective permanent molars.

What is incisal ridge?

The incisal ridge is that portion of the crown which makes up the complete incisal portion. When an incisor is newly erupted, the incisal portion is rounded and merges with the mesioincisal and distoincisal angles and the labial and lingual surfaces. This ridge portion of the crown is called the incisal ridge.

How do you identify molars?

Molars have an occlusal (chewing) surface with three to five cusps, and their occlusal surfaces are larger than the other teeth in their respective arches. They have broader occlusal surfaces than premolars, both facio- lingually and mesiodistally.

How do you identify maxillary right and left central incisors?

The right deciduous maxillary central incisor is known as “E”, and the left one is known as “F”. The permanent maxillary central incisors are designated by a number. The right permanent maxillary central incisor is known as “8”, and the left one is known as “9”.

What is mentalis strain?

Lip incompetence, also known as mentalis strain, refers to a condition characterized by an inability to easily hold the lips together while at rest. Other common features of lip incompetence include protruding lips, and strain in the lower facial region when you try to seal your lips.

What is RCP and ICP?

RCP = Retruded contact position. ICP = Intercuspal position. Pr = Maximum protrusion. R = Maximal mandibular opening with the condylar heads in the reproducible retruded position but no antero-inferior condylar translation.

What is the difference between incisal edge and ridge?

An incisal edge is sometimes confused with an incisal ridge. While an incisal ridge is the bottom portion of the tooth farthest from the gum, the incisal ridge refers to the angle on the tooth that occurs where two flat surfaces meet. This is the area between the teeth, farthest from the gum line.
