Abstract
BackgroundThis study aimed to verify the efficacy of two elastodontic devices in overjet (OJ) and overbite (OB) reduction during treatment with the Equilibrator Series II (Eptamed) and Occlus-o-Guide (Sweden & Martina) devices.MethodSixty patients aged 7–15 years were enrolled in the study, and were divided into test and control groups. The test group included 30 patients (14 males, 16 females; mean age, 10.66 ± 2.12 years) treated with the EQ (Equilibrator) Series II. The control group included 30 patients (15 males, 15 females; mean age, 10.76 ± 2.52 years) treated with the Occlus-o-Guide. The two groups exhibited the same orthodontic features. The orthodontic criteria were: skeletal and dental class II malocclusion (divisions 1 and 2); and the presence of OJ and OB. Evaluation of OJ and OB was performed at two timepoints: T0 (before starting therapy) and T1 (after 1 year).ResultsAt T0, OJ and OB were similar for the two groups; however, at T1, both OJ and OB were significantly lower with the Eptamed device compared to the Occlus-o-Guide device (p = 0.0019).ConclusionsElastodontic devices improve orthodontic outcomes by aiding orthodontic patient management, diagnosis, and treatment planning, reducing the risk relapse acting on the whole organism and the rehabilitation of the tongue.

Dental overjet (OJ) and dental overbite (OB) are two defects that frequently occur in Caucasian patients
NANHES III (National Health and Nutrition Survey III) showed that OJ is common in the patients affected by second and third skeletal class malocclusion
Summary
Dental overjet (OJ) and dental overbite (OB) are two defects that frequently occur in Caucasian patients. OJ is the extent of horizontal (anterior–posterior) overlap of maxillary central incisors over mandibular central incisors [1]. OB is the extent of vertical (superior-inferior) overlap of maxillary central incisors over mandibular central incisors. An OJ greater than or equal to 5 mm is associated to Class II malocclusion. According to Angle, it is evident in 23% of children, 15% of adolescents, and in 13% of adults. Negative OJ is often associated with Class III malocclusion, but is much less frequent. It occurs in about 3% of American children and 5% of adolescents and adults (https://www.cdc.gov/nchs/nhanes/nhanes_products.htm). This study aimed to verify the efficacy of two elastodontic devices in overjet (OJ) and overbite (OB) reduction during treatment with the Equilibrator Series II (Eptamed) and Occlus-o-Guide (Sweden & Martina) devices
