“…this percent ratio should be from 62% to 65% and then the face grows without rotation. if the percentage is higher, the face grows with anterior and if the percentage is lower it grows with posterior rotation (3,15).…”

The viscerocranium to neurocranium ratio is 1:8 in infants, while in adults, when growth has been completed, it reduces to 1:3. For orthodontists, it is important to determine the way the face or each jaw grows and thus predict further growth so that the right therapy can be chosen or an anomaly corrected. Therefore, it is necessary to make a head profile radiograph i.e. cephalometric radiograph of the patient's head. The aim of this study is to present the most frequently used methods for analysis of the cephalograms in order to determine the type of facial growth. Today, it is known that growth persists throughout adulthood, although at a slow rate.

“…The large variation in interindividual response to functional appliances may be due to several factors including compliance, appliance choice, growth potential, facial type, treatment timing, and skeletal maturity (Barton & Cook, 1997 ; Bishara & Ziaja, 1989 ; Carels & van der Linden, 1987 ; Celli et al, 2010 ; Tulloch et al, 1990 ; Woodside, 1998 ). Various cephalometric characteristics have been proposed to correlate to a favorable response to functional appliance treatment such as a low mandibular plane angle, low basal‐plane angle, high Jarabak ratio, short mandibular corpus and ramus height, short cranial base, and small anterior and posterior lower face heights (Kumar et al, 2013 ; Patel et al, 2002 ).…”

Background: Masseter muscle thickness and its relationship with vertical craniofacial morphology have been extensively studied in adults, but data on children are lacking.Objective: To examine the association between masseter muscle thickness and vertical cephalometric parameters in a group of Class II malocclusion growing children. Methods:The current study design was retrospective and cross-sectional, looking at a sample of 211 growing children with Class II malocclusion between the ages of 6 and 15 derived from two centers. Ultrasonographic masseter muscle thickness measurements and vertical cephalometric variables, including the gonial angle, were evaluated before any orthodontic treatment had been carried out. Multiple linear regression analysis was used to examine the association between masseter muscle thickness and vertical cephalometric measurements, including age and patient origin as independent variables in the analysis.Results: In the present sample, masseter muscle thickness was found to be independent of sex, but correlated with age, with older children presenting thicker masseter muscles. In the total patient sample, using multiple regression analyses, children with thicker masseter muscles had significantly smaller intermaxillary and gonial angles. No other cephalometric vertical characteristics showed associations with masseter muscle thickness. Conclusion:In growing children with Class II malocclusion, those with thicker masseter muscles are more likely to display smaller intermaxillary and gonial angles respectively.

“…However, many diseases are associated with the abnormality of circadian clocks in human rhythm [ 2 ]. Clinically, patients using orthodontic functional appliances at night demonstrate better treatment results than those using such appliances during the day [ 3 , 4 ]. Therefore, greater attention should be focused on the effects of circadian rhythm on muscle function.…”
