Maxillary Incisors Flashcards
What’s the narrowest and widest areas of incisors ?
Cervical narrow
Incisal wide
Which more symmetrical laterals or centrals ?
Centrals
What’s disguinsh lateral from centrals labial view ?
Laterals , more convex less flat M-D , mammelons , labial depressions less prominent than centrals.
What’s the difference between incisal angles of centrals and laterals ?
Laterals there distoincisal angle more round and shifted cervically
While in central it’s more horizontal
What’s the difference between line angles in both centrals and laterals ?
Mesial crown outline flatter, distal more rounded
What’s the difference between line angles in both centrals and laterals ?
Mesial crown outline flatter, distal more rounded
Where does mesial contact area of incisors located ?
Incisal 3rd
Centrals near incisal edge
Laterals same but more cervically
Where does distal contact area ?
Centrals near junction of incisal and middle 3rd
Lateral more cervical in middle 3rd
How does crown concavity appear in centrals and laterals ?
Centrals , deeper lingual crown concavity
Lateral , slightly shallower lingual crown concavity
How does roots concavity appears from proximal ?
Central More curved in lingual than labial
Lateral Root more taper fascially and lingually
Here more cervical curvature found in incisors ?
On mesial than distal
What’s the mesiodistal and F-L dimensions from incisal view ?
Mesial-distal more wider than fasciolingual in central
Laterals crown minimally wider M-D
How does crown outline appear from incisal view ?
Centrals , triangle
Laterals , oval or round
What’s the difference between incisal edge ?
Centrals curved mesiodistally
Laterals straight
Difference between cinglum location ?
Central more distally
Laterals centered
