Hi, I have a plenty of extracted lower incisors, I want to separate them as lower central and lower lateral incisors. They look very identical; please advise me some tips to separate them. In addition, easy tips for right or left side. It will be of great help.
Thanks in advance.
mesioincisal and distoincisal angles
In central both are sharp in lateral distal is comparatively rounded
Size
Lateral is larger as compare to central
From incisal aspect
Lateral incisal is more curved and central is straight
and a lot more
for lateral incisor - crown is bilaterally asymmetrical, as distal half is stretched to make contact with canine
when viewed incisally, lateral incisor the distal portion of the crowns tends to be shifted lingually
Dear friends, the difference in size is very little and still there will be an element of doubt.
in lateral distal is comparatively rounded can be helpful. I must be focusing disto-
incisal angles, many thanks
You have to measure the width of the tooth at incisal area as well as the length of the roots will be definitely guiding areas
there is also difference from lingual aspect lingual is more smooth in central which is not the case in lateral
`Dear zafar,
width and length of the root varies from both the teeth
Incisivo lateral presenta concavidad en tercio cervical de su cara proximal distal debido a su mayor longitud incisal. En borde incisal debe presentar dos desgastes, por oclusión con dos dientes (central y lateral superior).
Espero sea de ayuda
