“…Regarding the maxillomandibular relationship, there was a statistically significant (P ≤ 0.05) decrease of ANB angle that accounted for the minimal improvement of the sagittal intermaxillary jaw relationship. This was agreed with the results of studies (11,14,16,17,19,23,24,28) using PowerScope appliance and studies (20,21,22) using MARA, FFRD, and TFBC appliances. While a study (29) using Eureka Spring found no statistically significant change in the ANB angle.…”

“…There was a statistically significant (P ≤ 0.05) decrease in SNA angle which indicated the effect of Powerscope appliance on the restriction of the maxillary base that was agreed with the results reported by other Powerscope studies (23,24,16) in addition to studies (25,26,27) using Churro Jumper, Forsus Nitinol Flat Spring (FNFS), Jasper Jumper (JJ) and Sabbagh Universal Spring 2 (SUS 2) appliances. On the contrary, studies (11,14,18,19,17) using Powerscope appliance and other studies (20,21,22) using Mandibular Anterior Repositioning Appliance (MARA), Forsus Fatigue Resistant Device (FFRD) and Twin Force Bite Corrector (TFBC) appliances showed no statistically significant changes happened to SNA angle and consequently to the maxilla.…”

“…There was proclination of the lower incisor with a statistically significant increase of IMPA by 8.65˚ ±5.38˚, this agreed with the results of studies (11,23,14,16,17) using Powerscope appliance in addition to studies (20,25,29,21,27,22) using MARA, Churro Jumper, Eureka Spring, FFRD, SUS 2 and TFBC appliances. The findings were against the results of studies (28,24) using the Powerscope appliance, which showed no change in the lower incisor inclination.…”

“…There was a statistically significant (P ≤ 0.05) retroclination of the upper incisor with the decrease in U1-SN, which agreed with the results of Powerscope studies (14,23,24,28) in addition to studies (25,26,21) using Churro Jumper, FNFS, JJ, and FFRD appliances. On the contrary, studies (11,19,16,17) using Powerscope˚ appliance and a study (22) using TFBC showed no change in the upper incisor inclination.…”

“…The forward positioning of the chin takes place as a result of the action of the Powerscope appliance, which is explained by a statistically significant (P ≤ 0.05) increase in the Facial angle. This was also found in Powerscope appliance studies (18,19,23) and a Churro Jumper study (25) which showed a statistically significant anterior or forward position of Pog point indicating forward positioning of the mandible.…”

Objectives: This study was conducted to evaluate the efficacy of Powerscope appliance in the treatment of skeletal Class II patients by three-dimensional image. Subjects and methods: This study was conducted on 14 orthodontic patients with a mean age of 15.39 ± 1.25 years old. The study included post-pubertal female patients with skeletal Class 2 of ANB angle greater than 4° due to the retruded mandible. Cone-beam computed tomography was made before (T1) and after (T2) installation of the Powerscope appliance. The images were imported into Invivo dental software version 5.2 for the measurements. The collected data were tabulated and statically analyzed using Statistical Package for the Social Sciences (SPSS) version 23. Paired t-test was used to study the changes after treatment. The significance level was set at ≤ 0.05. Results: Results showed statistically significant changes regarding skeletal and dental parameters. Conclusions: (1) Powerscope appliance provides an effective tool for the treatment of skeletal Class II adolescent patients. (2) Effects of Powerscope appliance were mainly dental with lesser skeletal effects. (3) The skeletal changes were seen in the mandibular base with minimal maxillary skeletal effects.

Background: Fixed functional appliances are used for correcting Skeletal Class II due to retrognathic mandible. Objectives: The current study's goal was to assess and contrast the skeletal, dental, and soft tissue changes produced by PowerScope and AdvanSync2. The null hypothesis was that there were no significant differences in the treatment effects of both the appliances. Material and methods: A retrospective study was conducted on growing 75 female subjects with skeletal class II malocclusion, divided into 3 groups: Group 1: 25 Subjects of AdvanSync2 (Mean age- 12.61±1.52years); Group 2: 25 subjects of PowerScope (Mean age- 12.23±1.32years) and Group 3: untreated class II control sample of 25 subjects (Mean age- 12.91±0.92years). Lateral cephalograms were traced at T0 (pretreatment) and T1 (post functional) for measuring various skeletal, dental, and soft tissue parameters. ANOVA and Post Hoc Tukey test was used for comparison between the groups. Results: Statistically significant changes were seen in skeletal, dental, and soft tissue parameters with both appliances compared with the control group. AdvanSync2 had statistically significant restrictive effects on the maxilla (p<0.05), produced greater mandibular advancement, retraction and extrusion of the upper incisors, proclination of the lower incisors, overjet reduction, and distalization of the upper molars, whereas PowerScope had non-significant effects on the maxilla and mainly produced dentoalveolar changes with good overbite reduction. Both appliances greatly improved the soft tissue profile of the patients compared with that of the control group. Clinical implications: AdvanSync 2 is recommended for treating Skeletal Class II for better skeletal effects. Conclusions: The null hypothesis was rejected in this study. AdvanSync 2 produced better skeletal effects than PowerScope, which displayed better dentoalveolar changes.
