Ar-Go measurement describes the linear distance between articulare and gonion
providing the mandibular ramal length.
It has been found that the gonion
, orbitale, porion, menton and lower incisor apex were the most inconsistent and unreliable points (7,15) this might have contributed to the difference in FMA and L1 to MP.
Lower gonial angle: N-GO-ME###Measured at the angle between Gonion
The Condylon Gonion
Displacement Index (CGDI) was calculated by using the formula as detailed below.
PAS: measured between the posterior pharyngeal wall and the dorsum of the tongue on a line joining the gonion
to the B point
Ar, Articulare; Pog, Pogonion; Go, Gonion
; Gn, Gnathion; Co, Condylion; SMIs, skeletal maturation indicators (according to Fishman ).
* Mandibular angle left/right (MAL/MAR) (angle between gnathion, gonion
, lateral condyle).
These landmarks were the comissural abiorum, tragus, lateral canthus and gonion
. The study was designed as a split-mouth, single-blinded study in which the patient was blinded but the surgeon was not, and the left and right mandibular impacted third molars of each patient were allocated into the study and control groups through a coin-based randomisation and random numbers randomisation technique.
Gwylltiodd Nans yn gonion
ac atebodd "Meindia dy fusnas, wnes i ddim gofyn iti ddod yma i roi dy farn," a chanlynodd gyda'r fath iaith nes roeddwn i, ond plentyn, wedi dychryn braidd, a phenderfynais nad oedd Nans yn perthyn i Ysgol Sul tra bu'n byw yn Llundain.
Por otro lado, los puntos de referencia mandibulares fueron: menton (Me), e infradental (Id) y los puntos de referencia derechos e izquierdos de condilion (Cdd, Cdi) y gonion
(God, Goi) (figura 3).
