Comparison of short-term effects between face mask and skeletal anchorage therapy with intermaxillary elastics in patients with maxillary retrognathia

Abstract

The undesired dentoalveolar effects of the FM treatment were eliminated with SA treatment, except with regard to lower incisor inclination. Favourable skeletal outcomes can be achieved by SA therapies, which could be an alternative to the extraoral appliances frequently applied to treat skeletal Class III patients with maxillary deficiency.

Class III Treatment with Skeletal and Dental Anchorage: A Review of Comparative Effects

“…A total of 9 studies [ 20 – 28 ] were judged eligible for inclusion and are listed in Table 2 . Publications years are included between 2010 [ 21 ] and 2016 [ 20 , 28 ].…”

“…A total of 9 studies [ 20 – 28 ] were judged eligible for inclusion and are listed in Table 2 . Publications years are included between 2010 [ 21 ] and 2016 [ 20 , 28 ]. Only four studies were prospective [ 20 , 21 , 23 , 27 ], other four were retrospective [ 24 – 26 , 28 ], and, finally, only one was a randomized clinical trial [ 22 ].…”

“…Publications years are included between 2010 [ 21 ] and 2016 [ 20 , 28 ]. Only four studies were prospective [ 20 , 21 , 23 , 27 ], other four were retrospective [ 24 – 26 , 28 ], and, finally, only one was a randomized clinical trial [ 22 ]. The sample sizes ranged from a minimum of 20 subjects [ 25 , 28 ] to a maximum of 60 ones [ 26 ] with an average of 44.5 and, overall, there is not a clear difference between sex, even if there is a prevalence of treated female subjects; only one study [ 28 ] did not specify the gender of the treated group.…”

“…The age of patients at the beginning of therapy was between 8.1 ± 1.5 years and 11.9 ± 1.8 years [ 23 ]. Regarding the diagnosis of Class III malocclusion, the parameters used were the angle ANB [ 20 , 22 , 25 – 28 ], Wits [ 20 – 23 , 26 , 27 ], anterior cross-bite or a head-to-head relationship, used in almost all studies, and, finally, a Class III molar relationship [ 21 , 23 , 26 , 27 ]. One study [ 24 ] did not use skeletal parameters but they adopted negative overjet as the only parameter.…”

“…One study [ 24 ] did not use skeletal parameters but they adopted negative overjet as the only parameter. In two studies skeletal maturation was assessed at the first stage of treatment by hand and wrist radiography [ 20 , 27 ]. In the first study [ 20 ], all the patients were in a prepubertal growth phase, while in the second one [ 27 ] the subjects were in a phase ranging from prepubertal to peak pubertal growth.…”
