As a conclusion we have FH, MP, Li angle , correct position of lower incisor related to MP is a good indicator for stability, periodontal health (gingival recession)and aesthetics. so any proclination or retroclination should be within limit .
I have question pls , in cases usually the Li-FH is interchangeable from case to case not fixed 65-70 so what shall I do ? It maybe increased or decreased . Do I disregard it and focus on FMPA Aand Li-Mp ?
As you know, the angles of any triangle have to be 180 degrees, change of one angle will affect the others,so when we have a range from 22_32 (27+/_5) as FMPA or MMPA so the 10 degree difference will affect the other two angles ,then a rule of 120 - MMPA a raised... That rule means ( sum of li to MP+MMPA/ FMPA =120°

عندي سؤال ماهو سبب تثبيث قيمةزاوية FMIA?
